Invoice Software for India: The 2026 Buyer's Guide
How to choose GST-ready invoice software in India — CGST/SGST/IGST handling, PDF sharing, Razorpay collection, and what to avoid.
The right invoice software pays for itself in the first month, usually through faster collections. The wrong one adds a compliance risk and a monthly bill for nothing. Here is what actually matters when you're picking one in India.
Non-negotiable features
- Correct CGST/SGST vs IGST split by buyer's state.
- HSN / SAC codes per line item.
- Sequential invoice numbers unique per financial year.
- PDF export that looks good on WhatsApp.
- Razorpay UPI/card link on every invoice.
- CA-friendly monthly export.
Nice-to-haves that quietly change your business
- Auto-decrement inventory when marked paid.
- WhatsApp share with one tap.
- Automatic reminder cadence for overdue invoices.
- Multi-channel order → invoice (Amazon, Flipkart, Shopify).
How much should you pay?
₹0–₹1,000/month is the honest range for Indian SMBs. Anything over ₹5,000/month should include real automation and a human onboarding — not just PDF generation.
