India's vehicles need parts. And India has a lot of vehicles.

Over 320 million registered vehicles on Indian roads — two-wheelers, three-wheelers, passenger cars, SUVs, light commercial vehicles, heavy trucks, buses, tractors — each requiring regular maintenance, periodic replacement parts, and occasional repair components throughout a service life that often spans 10-15 years. The automotive aftermarket — the business of replacement parts, accessories, and maintenance products for vehicles already on the road — is one of India's largest and fastest-growing retail and wholesale sectors.

For the auto parts dealers who serve this enormous market — whether you run a multi-brand spare parts shop in a busy automotive market like Mumbai's Kurla, Delhi's Kashmere Gate, Chennai's Guindy, Pune's Budhwar Peth, or Bengaluru's Chickpet — or you operate as an authorised dealer for a specific automotive brand, or you run an online auto parts business supplying mechanics and workshops across the country — billing in 2026 carries specific requirements that generic business software was never designed to handle.

Auto parts billing is categorically different from general trading billing. Every transaction involves a part number — the specific OEM number or aftermarket catalogue number that identifies the exact component being sold. Part numbers are long, complex, and look deceptively similar (83741-02010 and 83741-02110 are different Toyota parts, not the same with a typo). Customers — mechanics, workshops, fleet operators — query by part number, vehicle application, or functional description. GST on auto parts spans 12%, 18%, and 28% — with specific high-value categories like tyres and batteries at 28%, most parts at 18%, and some categories at 12%. Warranties must be tracked from the date of sale. Return and exchange of defective parts is a regular operational event requiring correct credit note and GST reversal procedures.

This comprehensive guide covers every billing requirement specific to auto parts dealers across India — and how ERP Group's accounting software serves the unique operational and compliance needs of India's automotive parts retail and wholesale community.

Understanding India's Auto Parts Dealer Ecosystem

The Types of Auto Parts Dealers in India

India's automotive parts retail and wholesale sector comprises distinct types of dealers — each with specific billing requirements:

Authorised OEM Spare Parts Dealers

Dealers appointed by vehicle manufacturers — Maruti Genuine Parts dealers, Hyundai Genuine Parts dealers, TVS Genuine Parts dealers — to sell original equipment manufacturer spare parts. These dealers work within manufacturer-prescribed pricing structures, receive parts at designated trade prices, and are expected to maintain inventory of fast-moving parts for their brand's vehicle population.

Multi-Brand Aftermarket Parts Shops

Independent dealers stocking spare parts from multiple aftermarket manufacturers — Bosch, Minda, Valeo, Denso, Gabriel, NGK, Monroe, Wix, Mahle, and dozens of other aftermarket brands — for multiple vehicle makes. These dealers typically serve mechanics and workshops who want quality alternatives to OEM parts at competitive prices.

Two-Wheeler Parts Specialists

Dealers specializing in two-wheeler spare parts — Honda, Hero, TVS, Bajaj, Royal Enfield, Yamaha, Suzuki. Two-wheeler parts have their own part numbering systems, their own pricing structures, and their own high-velocity parts mix (air filters, spark plugs, brake pads, chain sprockets, indicators, mirrors).

Commercial Vehicle Parts Dealers

Dealers specializing in heavy commercial vehicle (HCV) and light commercial vehicle (LCV) parts — Ashok Leyland, Tata, Eicher, Mahindra, Force, BharatBenz. CV parts tend to be high-value, high-weight, and sold in smaller quantities to fleet operators and CV repair workshops.

Agricultural Vehicle Parts Dealers

Dealers for tractors and agricultural equipment — Mahindra Tractors, John Deere, Sonalika, New Holland, Swaraj. Located primarily in agricultural districts and mandis, these dealers serve farming communities.

Online Auto Parts Retailers

Increasingly significant — e-commerce auto parts platforms (CarDekho Parts, GoBumpr, SpareHub, Amazon Autoparts, Flipkart Automotive) and their supplier dealers. Online parts selling requires specific billing integrations with marketplace platforms.

India's Auto Parts Market Geography

The auto parts dealer market exists across every tier of Indian cities — from metro super-markets like Delhi's Kashmere Gate (one of Asia's largest auto parts markets), Mumbai's Kurla Complex, Chennai's Guindy, to district-level automotive markets serving local mechanics and workshops. The market is simultaneously national in scope (same vehicle models, same part numbers across India) and deeply local in character (each city's market has its own trading culture, credit practices, and dominant vehicle models).

GST on Auto Parts — Complete Rate Guide for Dealers

Why Auto Parts GST Requires Specialist Billing Software

Auto parts span three distinct GST rate tiers — 12%, 18%, and 28% — and two of the most high-value categories (tyres and batteries) sit at 28% while most other parts are at 18%. A dealer stocking all categories must correctly apply the right rate to every item — and generic billing software that defaults to one rate cannot handle this correctly.

Complete Auto Parts GST Rate Reference

12% GST — Specific Auto Parts Categories

Electric Vehicle Components (Specifically Notified):
Certain EV-specific components notified at 12% to support electric vehicle adoption — specifically EV charging equipment (HSN 8504) attracts 12% in many cases, and certain EV battery management components.

Retreaded Tyres (HSN 4012):
Retreaded or used pneumatic tyres — 12% GST versus 28% for new tyres. Relevant for dealers in commercial vehicle retreaded tyre segment.

Inner Tubes (HSN 4013):
Pneumatic inner tubes of rubber — 12% GST. An important distinction from the 28% outer tyre.

Bicycle Parts:
Bicycle parts and accessories (not motor vehicle) — 12% GST for dealers who also stock bicycle components.

Certain Automotive Safety Equipment:
Specifically notified safety components at 12%.

18% GST — The Primary Rate for Most Auto Parts

The vast majority of automotive spare parts attract 18% GST — this is the dominant rate for the auto parts dealer:

Engine Components (HSN 8409):
Pistons, piston rings, connecting rods, cylinder head gaskets, valves, valve springs, camshafts, crankshaft bearings, timing chains and belts — 18% GST. The largest volume and value category for most auto parts dealers.

Braking System Parts (HSN 8708):
Brake pads, brake shoes, brake discs, brake drums, brake calipers, master cylinders, wheel cylinders, brake hoses, ABS sensors — 18% GST.

Transmission and Drivetrain (HSN 8708):
Clutch plates, clutch pressure plates, clutch release bearings, gearbox components, CV joints, drive shafts, universal joints — 18% GST.

Suspension and Steering (HSN 8708):
Shock absorbers, struts, coil springs, leaf springs, ball joints, tie rod ends, rack and pinion components, power steering pumps — 18% GST.

Electrical Components (HSN 8511, 8512):
Spark plugs (HSN 8511), glow plugs, distributors, alternators, starters, ignition coils, sensors (oxygen sensors, MAP sensors, MAF sensors, crankshaft position sensors), relays, fuses, wiring harnesses — 18% GST.

Filters (HSN 8421):
Oil filters, air filters, fuel filters, cabin air filters — 18% GST.

Cooling System (HSN 8708, 8418):
Radiators, water pumps, thermostats, radiator caps, cooling fans, hoses — 18% GST.

Body and Exterior Parts (HSN 8708):
Bumpers, bonnet/hood, doors, fenders, trunk/boot lids (panels), door handles, mirrors (manual and power) — 18% GST.

Automotive Lighting (HSN 8512):
Headlight assemblies, tail light assemblies, fog lights, indicator assemblies, bulbs (halogen, LED) — 18% GST.

Automotive Glass (HSN 7007):
Windscreens, door glasses, rear windscreens — 18% GST.

Engine Oils and Lubricants (HSN 2710):
Motor oil, gear oil, brake fluid, power steering fluid, coolant — 18% GST. High-velocity category for auto parts dealers.

Automotive Accessories:
Car covers, seat covers (varies), steering wheel covers, floor mats (varies), dashboard accessories — generally 18% GST.

28% GST — Tyres, Batteries, and Specific Categories

Pneumatic Tyres (HSN 4011):
New pneumatic rubber tyres for all vehicle categories — passenger cars, two-wheelers, commercial vehicles, tractors — 28% GST. One of the highest-value categories for auto parts dealers.

Automotive Batteries (HSN 8507):
Lead-acid automotive batteries (car batteries, two-wheeler batteries, truck batteries) — 28% GST. Another high-value category where the 28% rate creates significant GST amounts on each transaction.

Air Conditioning Refrigerants (HSN 2903):
Automotive AC refrigerants (R-134a, R-1234yf) — 28% GST as chemical refrigerants.

Automotive AC Compressors:
AC compressors may attract 28% depending on specific classification — check current CBIC notifications.

The Critical Rate Distinctions Every Auto Parts Dealer Must Know

The Tyre-Tube Distinction

New tyre (HSN 4011) → 28% GST. Inner tube (HSN 4013) → 12% GST. Retreaded tyre (HSN 4012) → 12% GST. These three products look related but have very different GST rates — a dealer billing an inner tube at 28% overcharges significantly.

The Battery Distinction

Automotive battery (HSN 8507) → 28% GST. Battery charger (HSN 8504) → 18% GST. Two related products at different rates.

The Spark Plug Classification

Spark plugs (HSN 8511 10 00) → 18% GST as automotive electrical components. Often mistakenly billed at 28% by dealers who assume all automotive components follow the tyre/battery rate.

ERP Group's accounting software configures the correct HSN code and GST rate for every auto part in the catalogue — automatically applying the right rate at billing without requiring counter staff to know rates for thousands of parts.

Billing Challenges Unique to Auto Parts Dealers

Challenge 1 — Part Number Precision in High-Speed Counter Billing

Auto parts counter billing is fast-paced — mechanics don't wait. A workshop with a vehicle up on the lift is waiting for the part, the mechanic is time-pressured, and the counter person must find the right part quickly and generate the invoice without error.

Part Number Length and Complexity

OEM part numbers are long and complex — Toyota part numbers can be 10-12 characters, Bosch parts follow a specific numbering format, Mahindra part numbers follow their own structure. A single character difference means a different part (or a non-existent part that wastes time searching).

Similar Part Numbers for Different Applications

83741-02010 and 83741-02110 may look almost identical — but they are different parts for different vehicle models. Billing software must prevent confusion between similar part numbers through clear display and confirmation.

Challenge 2 — Multi-Keyword Part Search

Mechanics search for parts in multiple ways:

  • By OEM part number (if they have the old part or service manual)
  • By aftermarket part number (if they know the equivalent)
  • By vehicle model and year (to find compatible parts)
  • By functional description ("front shock absorber for Honda City 2019")
  • By component category ("all brake parts for Swift")

Billing software must support all these search modes — not just exact part number search.

Challenge 3 — OEM vs Aftermarket Alternatives

When a mechanic requests an OEM part, the dealer may:

  • Stock the OEM part (straightforward billing)
  • Not stock the OEM part but stock the equivalent aftermarket alternative
  • Stock both and want to offer the choice

Billing software must display both OEM and aftermarket alternatives with their respective stock levels and prices — enabling the counter person to offer alternatives when OEM is unavailable or too expensive for the customer's budget.

Challenge 4 — Warranty Tracking and Return Billing

When a mechanic returns a defective part within the warranty period:

Warranty Verification at Return

Has the customer actually purchased this part from this dealer? When was it purchased? Is it within the warranty period? Billing software must quickly verify warranty eligibility — linking the returned part to its original sale invoice.

Credit Note GST Reversal

The credit note for a returned part must carry the same GST as the original invoice — 18% credit note for an 18% original sale, 28% credit note for a 28% battery or tyre sale. Incorrect credit note GST creates ITC mismatches for workshop customers.

Challenge 5 — Battery Core Charge Management

Lead-acid battery returns involve core charges — deposits collected when the new battery is sold, refunded when the old core is returned for recycling.

Core Charge Billing

New battery sold at ₹4,200 + Core Charge ₹300 = Total ₹4,500. The ₹300 is a refundable deposit, not GST-taxable.

Core Return Credit

When the old battery is returned — credit ₹300 to the customer's account. ERP Group handles this two-transaction battery cycle correctly.

Challenge 6 — High-Volume Counter with GST Compliance

A busy auto parts counter generates 200-400 invoices per day. For dealers above the ₹5 crore e-invoicing threshold — all B2B invoices require IRN (Invoice Reference Number). Manual e-invoice generation for 300 daily invoices is impossible — auto parts billing software must generate IRNs automatically at billing speed.

Key Billing Software Features for Auto Parts Dealers

Feature 1 — Fast Part Number Search and Billing

Multi-Mode Part Search

ERP Group's accounting software supports part number search by:

  • OEM part number (exact match and partial match)
  • Aftermarket catalogue number
  • Brand + part description
  • Vehicle make-model-year application
  • Component category browse

Fast search results — displaying part name, brand, stock quantity, selling price, and GST rate — enable counter staff to complete billing in seconds per line item.

Similar Part Number Warning

When a part number is entered that closely resembles another part number in the catalogue, ERP Group alerts the counter person — preventing confusion between look-alike part numbers for different applications.

Feature 2 — Automatic GST Rate From Part Master

HSN-Based Rate Application

Every part in ERP Group's catalogue is configured with its 8-digit HSN code and correct GST rate. When a part is billed, the GST rate is applied automatically from the part master — counter staff never need to know or verify GST rates per part.

For tyres (28%), batteries (28%), most parts (18%), inner tubes (12%) — all applied correctly from the part master configuration without any manual rate selection.

Feature 3 — OEM to Aftermarket Cross-Reference at Billing

Cross-Reference Display

When a counter person searches for OEM part number 83741-02010, ERP Group displays:

  • The OEM part (if stocked) with its price and availability
  • All aftermarket equivalents linked in the cross-reference — Bosch equivalent, Minda equivalent, etc. — with their respective prices and stock

This cross-reference capability enables the dealer to make the sale even when the specific OEM part is out of stock.

Feature 4 — Warranty Verification at Return

Invoice-Linked Warranty Check

At the time of return, the counter person enters the original invoice number or the customer's name. ERP Group retrieves the original purchase — showing what was bought, when, at what price, and whether the part's warranty period (configured per part or brand) has expired.

Warranty-valid returns proceed to credit note generation. Expired warranty returns are handled as standard returns without warranty credit.

Feature 5 — Battery Core Charge Management

Automatic Core Charge Addition

When a battery is billed, ERP Group automatically adds the core charge as a separate line item on the invoice — with the correct treatment (deposit, not GST-taxable). When the core is returned, the credit transaction closes the core charge deposit.

Feature 6 — Counter POS for High-Speed Walk-In Billing

POS-Speed Billing

ERP Group's POS software provides auto parts counter billing at POS speed — fast part search, one-click billing, immediate invoice print or WhatsApp delivery, and e-invoice generation in the background for B2B customers.

Part Number and Catalogue Management

Building the Auto Parts Catalogue in ERP Group

The auto parts catalogue — the master database of every part stocked — is the operational foundation of an auto parts dealer's billing system. A well-configured catalogue enables fast billing; a poorly configured one creates daily billing delays and errors.

Part Master Structure in ERP Group

OEM Part Number

The manufacturer's official part number — printed on OEM packaging, referenced in service manuals and parts catalogues. Entered exactly as it appears on OEM documentation.

Internal Product Code

The dealer's own internal reference code — used for internal labeling and sometimes for shorter search.

Part Description

Clear, searchable description — "Brake Pad Set, Front Axle" or "Oil Filter, 2.0D Engine" — with sufficient detail to distinguish from similar parts.

Brand and Manufacturer

Which brand this part is — Toyota Genuine, Bosch, Minda, Gabriel, etc.

Vehicle Application

Which vehicles this part fits — make, model, year range, engine variant. For multi-application parts, multiple vehicle applications linked.

HSN Code and GST Rate

8-digit HSN code (e.g., 8421 23 00 for oil filters, 8511 10 00 for spark plugs) and correct GST rate derived from HSN classification.

Warranty Period

Standard warranty period for this part — 6 months, 12 months, 24 months — used for warranty eligibility verification at return.

MRP and Trade Price

Maximum Retail Price (if applicable) and current trade selling price.

Supersession Management

When OEM Part Numbers Change

Manufacturers regularly update part numbers — discontinuing old numbers and replacing with updated ones for the same part. ERP Group's supersession management links old part numbers to their current replacements — so when a customer asks for an old number, ERP Group automatically shows the current active part number and its availability.

Vehicle Compatibility and Cross-Reference Billing

Vehicle-Based Parts Lookup

The most natural way for a mechanic to search for parts is by vehicle — "I need the clutch kit for a 2018 Hyundai Creta 1.6 diesel." ERP Group supports vehicle-based parts lookup:

Vehicle Hierarchy

Make (Hyundai) → Model (Creta) → Year (2018) → Engine Variant (1.6 CRDI diesel) → Parts list for this specific vehicle application.

Application-Specific Results

Not all parts that fit a Creta 1.6 fit a Creta 2.0 petrol — the lookup filters to vehicle-specific compatible parts only, preventing the common mistake of selling the wrong part for a slightly different vehicle variant.

Cross-Reference Management

OEM to Aftermarket

The same clutch kit may have:

  • Hyundai OEM number: 41100-32020 (Valeo manufactured)
  • Valeo direct number: 832536
  • LuK equivalent: 624 3316 09
  • AISIN equivalent: CSD-062

ERP Group maintains these cross-references — so a mechanic asking for any of these part numbers finds all available options in the dealer's inventory.

Aftermarket to OEM

When a customer brings an old aftermarket part to find the equivalent — ERP Group's reverse cross-reference identifies the OEM part number and all equivalent aftermarket alternatives stocked.

For a deeper understanding of how a large auto parts distributor manages complex OEM and aftermarket catalogues, read our guide on ERP for Chennai auto parts distributors — the catalogue management principles apply equally to retail dealers across India.

Warranty and Return Management

The Warranty Ecosystem in Auto Parts Retail

Auto parts warranties work through the distribution chain — the part manufacturer warrants the part to the dealer, and the dealer warrants it to the mechanic or end customer. When a part fails within warranty:

Customer Returns Part to Dealer

The mechanic returns the defective part with the original invoice. ERP Group verifies warranty eligibility — invoice date, part number, configured warranty period.

Dealer Issues Credit to Customer

Credit note generated in ERP Group — at the original invoice price with the correct GST rate. The mechanic receives either replacement part or credit.

Dealer Claims from Distributor or Brand

The dealer sends the defective part to their supplier (distributor or OEM brand depot) with a warranty claim — requesting replacement or credit. ERP Group tracks this open claim against the specific supplier.

Supplier Credit Settlement

When the distributor or brand settles the warranty claim — credit note received, entered in ERP Group against the pending claim. The warranty cycle closes.

Defective Returns Without Warranty

For parts returned outside warranty period or without clear warranty defect:

Return to Stock (If Resaleable)

Parts in resaleable condition returned to inventory — credit note to customer at current pricing.

Write-Off for Damaged Returns

Parts damaged beyond use — write-off with ITC reversal as required.

Counter Billing for Mechanics and Walk-In Customers

The Auto Parts Counter Billing Reality

An auto parts counter at a busy shop in Kashmere Gate, Delhi or Chickpet, Bengaluru serves 150-300 customers per day — mechanics on bikes looking for one part, workshop service advisors buying 5-10 items for multiple jobs, fleet operators placing bulk orders, and walk-in vehicle owners buying accessories.

Speed and Accuracy at the Counter

Part Search Speed

The counter person types 3-4 characters of the part number or description — ERP Group returns matching results instantly. No waiting, no page loading.

Stock Availability at Point of Query

When a part is searched, ERP Group immediately shows available quantity in stock — enabling the counter person to confirm availability before the customer is waiting. "Yes, we have 2 units of that oil filter in stock" versus "Let me check in the store" — the difference between a 30-second sale and a 5-minute delay.

Alternative Part Suggestion

If the requested part is out of stock, ERP Group automatically shows available alternatives — equivalent aftermarket brands in stock — so the mechanic leaves with a part rather than empty-handed.

Invoice in Seconds

ERP Group's POS software generates the invoice in seconds — with automatic GST calculation, optional printing to the counter printer, or direct WhatsApp delivery of the digital invoice to the mechanic's phone.

Cash, UPI, and Card Payment Management

Modern auto parts counters accept multiple payment modes:

Cash

Still dominant for many mechanic customers — counted, verified, and recorded against the invoice.

UPI (PhonePe, GPay, Paytm)

QR code scan payments — ERP Group records UPI payment reference against the invoice.

Card Payments

Debit and credit card — ERP Group records card payment reference.

Credit Account

Trusted mechanic and workshop customers buy on credit — payment settled weekly or monthly. ERP Group tracks credit outstanding per customer account.

Workshop and Service Centre Account Management

Workshop Accounts — The B2B Core of Auto Parts Business

Regular workshop customers — multi-brand service centres, two-wheeler service centres, commercial vehicle repair garages — are the core B2B revenue of most auto parts dealers. Managing these accounts well is the key to long-term dealer success.

Workshop Account Features in ERP Group

Credit Account Management

Each workshop has a credit limit and credit terms — "Pay within 15 days, credit limit ₹1 lakh." ERP Group tracks outstanding balance per workshop, flags accounts approaching credit limit, and generates aging reports for collection management.

Workshop Purchase History

Complete purchase history per workshop — what parts they buy most, how frequently, in what value. This purchase history informs the dealer's stock planning (which parts to keep extra stock of) and the sales team's upselling conversations.

Dedicated Billing for Workshop Accounts

Workshop accounts often receive special pricing — trade discounts on selected categories. ERP Group maintains workshop-specific price lists — automatically applying the correct price tier when billing any account.

ERP Group's CRM software manages the complete workshop relationship — contact details, purchase history, credit account, outstanding balance, and collection follow-up records.

Fleet Operator and Corporate Accounts

Fleet operators — transport companies, taxi aggregators, delivery companies — maintain large vehicle fleets requiring regular parts. These accounts tend to be high-value, multi-location buyers:

Fleet-Specific Pricing Agreements

Fleet operators negotiate specific pricing for high-volume purchases of frequently needed parts — tyres, batteries, brake pads, engine oils. ERP Group maintains fleet pricing agreements per account.

Fleet Vehicle Tracking (Optional)

Some dealers track which parts were purchased for which fleet vehicle — enabling service history tracking per vehicle number, useful for both the fleet operator and the dealer's account management.

Battery and Tyre Billing Specifics

Battery — The Core Charge Complexity at 28% GST

Batteries are among the most complex auto parts to bill correctly — high value, 28% GST, and the core charge system.

Battery Sale Invoice Structure

New Exide 35Ah Battery for Maruti:

  • Battery price: ₹3,800
  • GST at 28%: ₹1,064
  • Core charge (deposit): ₹350
  • Total invoice: ₹5,214

The GST applies on ₹3,800 (battery value). The ₹350 core charge is a refundable deposit — not subject to GST. ERP Group calculates this correctly — 28% GST on battery price only, core charge as a separate non-GST line.

Core Return Transaction

When the old battery is returned:

  • Core charge refund: ₹350
  • Credit to customer account or cash refund

ERP Group records the core return and credit — closing the core charge deposit entry and updating the customer's account.

Tyre Billing at 28% GST

Tyre-Tube-Flap Set Billing

Many tyre purchases include inner tube and flap (for tube-type tyre applications):

  • Tyre (HSN 4011): ₹2,400 × 28% GST = ₹672
  • Inner tube (HSN 4013): ₹180 × 12% GST = ₹21.60
  • Flap (HSN 4012): ₹60 × 12% GST = ₹7.20

Three items on the same invoice at three different rates — ERP Group handles each at its correct rate from the part master configuration.

Tyre Installation Service

If the dealer also provides tyre fitting, balancing, and alignment services — these are billed as service at 18% GST (labour/service), separate from the 28% tyre product.

Inventory Management for Auto Parts Shops

Managing High-SKU Auto Parts Inventory

A mid-sized multi-brand auto parts dealer may stock 3,000-8,000 part numbers — from washers costing ₹2 to complete engine assemblies costing ₹50,000+. Effective inventory management is operationally critical — stockouts mean lost sales and frustrated mechanics, overstocking ties up working capital in slow-moving parts.

Fast-Moving vs Slow-Moving Parts Analysis

Velocity Classification

ERP Group classifies parts by sales velocity — fast-moving (A category: sold multiple times daily), medium-moving (B category: sold weekly), and slow-moving (C category: sold infrequently). This velocity classification drives:

  • Stocking quantity: Fast movers need higher safety stock
  • Reorder frequency: Fast movers reorder more frequently
  • Physical placement: Fast movers near the counter, slow movers in deeper storage

Dead Stock Identification

Parts that have not sold in 6-12 months become dead stock — tying up working capital and physical space. ERP Group's slow-moving and dead stock report identifies these parts for clearance action.

For a complete guide to inventory aging and dead stock management, read our guide on stock aging analysis for wholesale business.

Reorder Level Management

Minimum Stock Level by Part

ERP Group allows configuration of minimum stock levels for each part — particularly fast-moving parts where stockout is commercially unacceptable. When stock falls below the minimum, ERP Group generates a reorder alert.

Automatic Purchase Order Generation

For a parts shop with predictable reorder patterns, ERP Group can automatically generate purchase orders when stock falls below reorder level — reducing the manual effort of reorder management for a catalogue of thousands of parts.

ERP Group's warehouse management system manages auto parts inventory at bin-location level — knowing not just how many units of each part are in stock but where in the store they are physically located.

Labour and Payroll for Auto Parts Shop Staff

The Auto Parts Shop Workforce

A mid-sized auto parts shop typically employs:

  • Counter sales staff (2-5 persons)
  • Store and inventory staff (1-3 persons)
  • Delivery staff for workshop deliveries (1-2 persons)
  • Accounts and billing staff (1-2 persons)
  • Manager/proprietor

Many established auto parts shops exceed the ESI (10 employee) threshold and some exceed the PF (20 employee) threshold.

PF and ESI for Auto Parts Shop Staff

ERP Group's HR & Payroll software manages the complete auto parts shop payroll — fixed salaries for counter staff, delivery staff allowances, PF and ESI compliance, and monthly statutory filing.

For the complete guide to PF and ESI rules and compliance for shops and establishments, read our guide on PF ESI deduction rules for traders India — applicable equally to auto parts retail businesses.

Frequently Asked Questions

The majority of automotive spare parts — engine components, brake parts, suspension parts, transmission parts, filters, electrical components, cooling system parts, body parts, and lighting — attract 18% GST under HSN Chapter 8708, 8409, 8421, 8511, 8512, and related chapters. However, two important high-value categories are at 28% GST: pneumatic automotive tyres (HSN 4011) and automotive batteries (HSN 8507). At the lower end, inner tubes (HSN 4013) and retreaded tyres (HSN 4012) attract 12% GST. Engine oils and lubricants (HSN 2710) are at 18% GST. Getting these rates correct matters significantly — a battery worth ₹3,800 creates ₹1,064 in GST at 28%; billing it at 18% would under-charge by ₹380 per battery. ERP Group configures the correct HSN code and GST rate for every part in your catalogue — the rate applies automatically at billing from the part master, without counter staff needing to know or verify rates for thousands of individual parts.

The battery core charge — the deposit collected when a new battery is sold, refundable when the old battery is returned — is not subject to GST because it is a refundable security deposit, not consideration for supply of goods or services. ERP Group handles battery billing with two separate line items: the battery supply (at ₹3,800 with 28% GST = ₹1,064) and the core charge (at ₹350 as a deposit with no GST). The invoice total is ₹5,214 (₹4,864 + ₹350 deposit). The ₹350 is recorded in ERP Group as a liability — amount owed back to the customer when they return the old core. When the old battery core is returned, ERP Group generates the core return transaction — crediting ₹350 to the customer's account or processing a cash refund. The deposit liability account is cleared. This two-transaction structure correctly accounts for the battery economics without incorrectly charging GST on the deposit component.

ERP Group's warranty return workflow starts with the original invoice retrieval. The counter person searches by the customer's name, invoice number, or part number — ERP Group pulls up the original purchase record showing the alternator, purchase date (8 months ago), part number, price paid, and GST charged. ERP Group compares the purchase date against the configured warranty period for alternators (12 months) — confirming the return is within warranty. A credit note is generated at the original invoice price with the same GST rate (18% on the original alternator price). The mechanic receives either a replacement alternator or a credit note for the value. ERP Group creates a warranty claim record for the specific part and batch — which you then submit to your distributor or the alternator brand's service network for reimbursement. The warranty claim tracks as a receivable from the supplier until they settle — either by providing a replacement or issuing a credit note. ERP Group shows all outstanding warranty claims with their aging — so you know which claims are pending and which have been settled.

Yes — this is one of ERP Group's core capabilities for auto parts dealers. Within a single invoice, ERP Group applies different GST rates to different line items based on each part's HSN configuration in the product master. When a mechanic buys a MRF Zapper tyre and a tube on the same bill: the tyre line item automatically attracts 28% GST (HSN 4011) and the inner tube attracts 12% GST (HSN 4013). The invoice correctly shows two separate rate sections — 28% sub-total and 12% sub-total — with correct GST amounts for each. This multi-rate single invoice is what GST law requires for mixed-rate transactions. The invoice also correctly feeds into GSTR-1 — with HSN-wise GST amounts at 28% and 12% reported separately. For a busy tyre shop billing 50-100 such mixed-rate invoices per day, this automatic rate segregation is essential for accurate GST compliance without any manual intervention by counter staff.

ERP Group's receivables management for auto parts dealers handles large numbers of credit accounts systematically. Each workshop is configured with its credit limit and payment terms (15-day, 30-day, etc.). Outstanding invoices for each workshop are tracked individually — not just as an account balance but at the invoice level. The receivables aging dashboard shows every credit account's outstanding by age bracket — current, 15-30 days overdue, 31-60 days overdue, 60+ days overdue. Accounts approaching their credit limit are flagged — enabling the billing counter to alert the customer or hold further credit. For collection follow-up, ERP Group's CRM software records each collection interaction — payment promises, dispute notes, and follow-up schedules — against specific outstanding invoices. Weekly collection reports prioritize which accounts to follow up based on amount outstanding and days overdue.

ERP Group maintains part supersession relationships — linking discontinued OEM part numbers to their current active replacements. When Toyota updates part number 83741-02010 to 83741-02010-A (or a completely different new number), you enter this supersession relationship in ERP Group. From that point: any customer or counter person searching for the old number (83741-02010) is automatically redirected to the new number (83741-02010-A) with a notification that the part has been superseded. Stock of the old number in inventory is shown as the physical product (which may be either the old or new number if Toyota ships interchangeably), and all future ordering uses the new number. For dealers stocking hundreds of frequently updated OEM parts, supersession management prevents the frustrating situation where a part appears to be out of stock because it is searched under the old number while the current number has plenty of stock.

ERP Group's certified IRP API integration handles e-invoicing at any billing volume — generating IRN automatically for every qualifying B2B invoice at the moment of billing. For 250 daily invoices to GST-registered workshop and fleet customers, all 250 IRNs are generated automatically within the normal billing workflow — no separate IRP portal login, no manual IRN generation. The billing counter person creates the invoice in ERP Group (same process as any other invoice). ERP Group submits to the IRP API in the background, receives the IRN within seconds, and the invoice prints with the IRN and QR code embedded. For dealers where the B2B threshold of ₹5 crore has been crossed (which includes most established multi-brand shops in metro automotive markets), this automatic e-invoicing compliance is built into the billing process — ensuring complete compliance without operational overhead.
