No bloated ERP, no spreadsheet gymnastics - just the core tools to bill customers and get paid, built India-first. Every feature below is free during beta with no per-invoice or per-user limit.
Core invoicing & billing
- GST auto-detection - CGST + SGST for intra-state, IGST for inter-state. It's picked up from the customer's state automatically - no manual math, no wrong-state mistakes.
- One-click PDF - Letterhead, logo, signature, HSN/SAC and amount in words (Indian format). Download or print a pixel-perfect, GST-compliant PDF every time, in five professional template styles.
- Draft → Issued flow - Edit drafts as much as you want. Issue to lock the number and make it legally final - atomic FY-aware numbering means no duplicates and no gaps.
- Partial payments & TDS - Record advance and part payments (with TDS), and track the balance at a glance. Status moves Final → Partially paid → Paid, and a receipt PDF is generated automatically.
- Customer book - Save customer details once - GSTIN, address, state - and reuse them across invoices. The GST tax mode auto-fills from the customer state.
- Payment reminders - Automatic email nudges at 0 / 3 / 7 / 15 / 30 days past due, or a one-tap WhatsApp follow-up. Chase payments less, get paid sooner.
- Credit notes (GST Section 34) - Raise credit notes against an issued invoice with reason codes, in the CBIC Section 34 format for returns, adjustments and disputes.
- Quotations that convert - Send a price proposal (proforma) and convert it to a tax invoice in one click when the customer accepts. Quotations use a separate FY-aware series.
- Cash memos - Issue cash memos for over-the-counter sales, with automatic CGST/SGST split and thermal-printer-friendly output.
- Multi-GSTIN / multi-branch - Run multiple companies or state branches from one login - each entity gets its own GSTIN, logo and numbering series, one click to switch.
- Reports for your CA - GSTR-1 CSV, a GSTR-3B summary, receivables aging and a P&L (accrual, cash and GST views) - everything your accountant asks for at month-end.
- One-click backups - Download a full ZIP of your invoices, customers and PDFs anytime, or schedule it to email itself monthly. Your data, your move - never locked in.
Why not just Excel?
Most Indian SMEs still copy-paste an old invoice, fiddle with GST math and email the file. That means manual CGST/SGST/IGST calculations (one wrong state and the invoice is non-compliant), hunting for HSN/SAC codes, writing amounts in words by hand, FY-end numbering that trips up in audit, and invoice_final_v3.xlsx version chaos. Apna Invoice does the GST split automatically, keeps HSN/SAC handy, writes proper Indian amount-in-words, resets numbering on 1 April, and shares a preview-ready PDF straight to WhatsApp.
