GST Billing Software for Indian Businesses

Getting GST right is not really about the tax rate. It is about everything that has to line up around it — the correct HSN on every line, CGST and SGST splitting properly for a local sale and IGST for an interstate one, an invoice number series that does not break, and returns that reconcile with what you actually billed. QuickBillBook handles that chain from the moment you create a bill to the moment you file.

Where GST billing usually goes wrong

Tax calculated by hand

One mistyped rate on one line, and the invoice total, the GSTR1 summary and your books all disagree.

Interstate confusion

Knowing when to apply IGST instead of CGST plus SGST depends on place of supply, and getting it wrong means a revised return.

Return time is a scramble

Data lives in a billing book, a spreadsheet and the accountant's file, and none of them quite match.

Missing HSN codes

Invoices go out incomplete, and the problem only surfaces weeks later when the buyer's ITC does not match.

How QuickBillBook handles it

Tax applied from the item

Set the GST rate and HSN on a product once. Every invoice that includes it calculates correctly, every time.

Place of supply decides the split

Pick the party, and CGST/SGST or IGST follows from their state. You do not have to remember the rule.

Returns come from your billing

GSTR1, GSTR2 and GST3B are generated from the invoices you already raised. There is no second round of data entry.

Export to Excel

Every GST report exports cleanly, so your accountant works from your figures rather than rebuilding them.

What is included

Frequently asked questions

Is QuickBillBook GST compliant?

Yes. Invoices carry the tax breakup, HSN or SAC codes and party GSTIN required under GST, and the GST reports are produced from the same data.

Does it handle interstate sales?

Yes. Place of supply is taken from the party's state, so IGST is applied on interstate sales and CGST plus SGST on local ones.

Can I generate e-invoices?

Yes, on plans that include e-invoicing. IRN and the signed QR code are generated from the invoice screen.

Do I need separate accounting software?

No. Ledgers, outstanding, purchase and sales registers and GST reports are all part of QuickBillBook.

Can my accountant get the data?

Yes. Every report exports to Excel.
