What “free GST billing software” should still include
Indian small businesses search for free GST billing software because paid suites feel heavy. Free should not mean broken tax logic. At minimum you need correct CGST + SGST or IGST, clean financial-year invoice numbers, PDF/email, and a customer list with GSTIN.
GST billing, inventory and a free store together
Try Finex Business
One catalog powers invoices, stock and your public store or showcase — without hiring a developer.
Finex Business is built as a GST billing solution you can start without a card — then grow into inventory and a free online store when you are ready.
Must-have GST features in 2026
- Place-of-supply aware tax (intra-state vs inter-state)
- Tax-inclusive and tax-exclusive line pricing
- Bill of supply / export-friendly flows where you need them
- Receivables view: paid, partly paid, overdue
- Sales and tax summaries you can export
If a tool only prints a PDF template and leaves tax math to you, it is not GST billing software — it is a stationery app.
Why billing + inventory + website wins
Most shops also need free inventory management and a simple website. When catalog, stock and invoices share one item list, you stop fixing mismatches every week. Finex publishes that same catalog as a free store or showcase page.
