Invoicing as a deterministic action

Every invoice creates correct journal entries, calculates GST from state codes, and generates a PDF — whether triggered by a human or an AI agent.

Tax Invoice / Bill of Supply

Hisaabo automatically selects the correct document type based on your GST registration status. GST registered? Tax Invoice. Not registered or exempt? Bill of Supply.

Line Items with Tax and Discount

Add unlimited line items with quantity, rate, discount (percentage or flat), and tax rate. Each line shows taxable value and tax amount separately.

A4, A5, and Thermal PDF

Generate invoices in A4 portrait, A5 landscape (compact and unique), or thermal receipt format for POS printers. Every format is print-ready.

UPI QR with Amount

Each invoice includes a UPI QR code pre-filled with the invoice amount. Your customer scans, confirms, and pays -- no manual entry of the amount.

Bank Details on Invoice

Add your bank account details once. They appear on every invoice so customers can pay via NEFT/RTGS/IMPS without asking you for details.

Custom Invoice Prefixes

Use prefixes like INV-, SI-, or your own format. Numbers auto-increment atomically. No duplicates, no gaps, no manual tracking.

Multi-Business Support

Run multiple businesses from one account. Each has its own parties, items, invoices, numbering, and GST settings. Switch between them instantly.

Differentiator

The A5 landscape format

Most billing software only offers A4 portrait. Hisaabo's A5 landscape format fits two invoices on a single A4 sheet -- cutting your paper costs in half.

  • Compact format preferred by retail and wholesale businesses
  • Print two per A4 page -- save 50% on paper
  • All mandatory fields included -- fully GST compliant
  • Easy to file and store -- takes less physical space

A5 Landscape -- 210 x 148mm
