GST invoicing software
Everything a GST tax invoice needs
GST mode turns Simple Billing into a compliant tax-invoice generator for goods and services — intra-state or inter-state, it applies the right tax the moment you pick a place of supply.
Correct tax split, automatically
Enter a rate once and the invoice splits it into CGST + SGST for intra-state sales, or IGST for inter-state — based on the customer's place of supply. Round-off is handled to the paisa.
HSN, SAC and GSTIN on every bill
Store your GSTIN and each customer's, add HSN or SAC codes per line item, and the tax invoice prints them exactly where a GST invoice is expected to show them.
Compliant tax-invoice PDF
The boxed 'TAX INVOICE' format shows the CGST/SGST/IGST columns, taxable value, place of supply, amount in words, and an authorised-signatory block your customers and CA recognise.
Tax summary your CA will thank you for
Export a period-wise summary of taxable value and tax by rate — this month, last month, or a custom range — as a CSV that drops straight into your filing workflow.
UPI QR to get paid faster
Add your UPI ID and every invoice carries a scan-to-pay QR, so customers settle a GST bill from GPay, PhonePe, or Paytm in seconds.
Narrow scope, always fast
No inventory, no ledger, no ERP bloat. It does GST invoicing and payments — which is exactly why it stays quick to use at month-end.
GST invoicing without the accounting-suite overhead
Most GST software in India is really an accounting suite with invoicing bolted on — heavy, slow, and priced for a finance team. If all you need is to raise correct tax invoices and know what you're owed, that's a lot of software to fight every day.
Simple Billing takes the opposite approach. Turn on GST mode and you get compliant CGST/SGST/IGST invoices, HSN/SAC codes, place-of-supply logic, and a tax summary for your accountant — and nothing you'd have to switch off. The result is a tool a shop owner, trader, or service business can actually run without training.
Because tax is calculated the same way every time, the number on screen matches the PDF your customer receives and the total your CA reconciles. That consistency — not a longer feature list — is what keeps GST billing painless.

FAQ
GST invoicing software — FAQ
- Does it split tax into CGST, SGST and IGST automatically?
- Yes. You enter a single GST rate on the line item, and the invoice applies CGST + SGST for intra-state supplies or IGST for inter-state supplies based on the customer's place of supply. The split, totals, and round-off are calculated for you.
- Can I add HSN / SAC codes and GSTIN?
- Yes. Store your business GSTIN and each customer's GSTIN, and add an HSN or SAC code to every catalog item. They appear on the tax-invoice PDF in the standard GST layout.
- Is the invoice a valid GST tax invoice?
- The PDF uses the boxed 'TAX INVOICE' format with taxable value, CGST/SGST/IGST columns, place of supply, GSTINs, amount in words, and an authorised-signatory block — the elements a GST tax invoice is expected to carry.
- Does it file GST returns for me?
- No — Simple Billing is invoicing software, not a return-filing or accounting suite. It gives you a clean period-wise tax summary (CSV) that you or your CA use to file. Keeping that scope narrow is what keeps it fast.
- Is there a free plan?
- Yes. The free plan covers one business and 50 invoices a year with GST invoices, PDF export, and payment tracking — no credit card required to start.
