Invoicing software that gets paid, not just prints.

What is invoicing software?

Invoicing software replaces the Word template or the printed bill book with a tool that creates, sends and tracks your invoices for you. In India, "invoicing" and "GST" can't really be separated — a bill has to carry the right tax, the right HSN/SAC code and the right place of supply, because those numbers are what your GST returns are built from later.

TatvaBooks gets this right at the moment you raise the invoice, not as a clean-up job before filing. It's built by Chartered Accountants specifically for Indian GST — not a generic template adapted for India after the fact.

GST-correct invoices at source

Every invoice you raise on TatvaBooks works out:

• CGST / SGST / IGST — decided automatically from your state and your customer's, not left for you to pick.
• HSN / SAC codes — captured at the item level so every line carries the correct code.
• Place of supply — validated when you save the bill, so a wrong-state invoice gets caught at entry, not at filing.

The result: your GSTR-1 and GSTR-3B workings roll up ready to review, because they're built from invoices that were correct from the start. See the full mechanics on our GST billing software page, and the layout rules on our invoice format guide.

Get paid faster

An invoice only matters if it gets paid. TatvaBooks lets you share a bill as a PDF or a shareable link, and shows you at a glance which invoices are paid, part-paid or overdue — so chasing receivables doesn't depend on a memory or a side spreadsheet. You always know who owes you what, and since which.

Credit & debit notes

Returns, price corrections and cancellations happen — TatvaBooks lets you raise a credit or debit note directly against the original invoice, so the GST reverses exactly the way the law expects and the adjustment flows into your GSTR-1 workings automatically, with no manual journal entry required.
