WHAT'S INCLUDED

Complete Features of ERP Group's Accounting Software

A complete cloud accounting platform — GST-ready, CA-friendly, and built for the unique needs of Indian businesses across retail, manufacturing, services, and distribution.

GST Tax Invoice

Generate GST-compliant B2B and B2C tax invoices in seconds. CGST, SGST, and IGST auto-calculated based on the buyer's state — zero manual tax entry.

E-Invoice (IRN) Generation

Auto-generate IRN (Invoice Reference Number) and embed QR code in every applicable B2B invoice — mandatory for businesses above ₹5 crore turnover. No IRP portal login needed.

Delivery Challan

Generate delivery challans for goods dispatched without a tax invoice — fully compliant with GST transit requirements. Linked to E-Way Bill generation automatically.

Credit Note & Debit Note

Issue GST-compliant credit notes for sales returns and price adjustments. Debit notes for additional charges — both linked to original invoices with automatic GST liability correction.

GST Reports (GSTR-1 Ready)

Generate GSTR-1 data directly from invoices — pre-formatted and ready to upload to the GST portal on the 11th. Save hours of manual compilation every month.

E-Way Bill Generation

Generate e-way bills directly from invoices for goods worth over ₹50,000 in transit — without logging into the GST portal separately. E-Way Bill data auto-pulled from the invoice.

Multi-GSTIN Support

Manage multiple GST registrations across states from a single ERP account. Each GSTIN maintains a separate invoice series, GST ledger, and filing-ready data set.

Recurring Invoice Automation

Automatically generate and send monthly or periodic invoices for subscription customers and retainers — with GST applied correctly every time, no manual re-entry.

WhatsApp Invoice Delivery

Send GST invoices directly to customers on WhatsApp with one click — PDF attached automatically with a UPI payment link. No manual downloads or forwarding.

Automated Payment Reminders

Schedule WhatsApp and email reminders automatically — 3 days before due date, on due date, and after. Reduce overdue invoices without manual follow-up calls.

Payment Tracking & Dashboard

See invoice status in real time — paid, partially paid, overdue, or pending. Know exactly who owes money, how much, and since when — from one dashboard.

Bank Payment Link Integration

Add a UPI or NEFT payment link to every invoice so customers can pay directly from the invoice — via PhonePe, Google Pay, Paytm, or net banking. No separate follow-up needed.

⚡ E-Invoicing Mandate — Government of India

Turnover above ₹5 crore? E-Invoicing (IRN) is now mandatory for every B2B invoice.

Non-compliance attracts a penalty of ₹10,000 per invoice or 100% of tax due — whichever is higher. ERP Group auto-generates IRN and embeds the QR code in your invoice PDF. No separate IRP portal login. No extra steps.
