Make GST invoices, bills of supply, quotations, delivery challans and credit notes in your browser. Every invoice gets a UPI QR code and can be shared on WhatsApp, and GSTR-1 files are ready at month end. No signup, no download, no invoice limits, no watermark and no paid plan waiting later.
Everything a GST invoice needs is on it: your GSTIN and state, a running invoice number for the financial year, the buyer's GSTIN and place of supply, HSN or SAC codes, taxable value, CGST and SGST or IGST at the right rate, round off, the amount in words and your bank details.

If most of your sales come through a website, Instagram or WhatsApp, you shouldn't be typing invoices at all. D2 Commerce OS runs your online store and raises a GST invoice for every order automatically, with credit notes when orders are cancelled, plus UPI and COD checkout, delivery and WhatsApp updates. It's free forever up to 100 orders a month.

No. It runs in your web browser on a computer, tablet or phone. Open the app link and start billing. You can add it to your phone's home screen for quick access.

Yes. Enter the customer's GSTIN or state and the app works out the place of supply. Same state as yours gets CGST and SGST; a different state gets IGST. Rates of 0%, 0.25%, 3%, 5%, 12%, 18%, 28% and 40% are available.

It exports GSTR-1 data as CSV files in the GST offline tool layout: B2B, B2CL, B2CS, credit and debit notes, HSN summary and documents issued. You or your CA can review them and upload through the offline tool.
Not yet. E-invoicing with IRN is required only above the notified turnover limit, and both e-invoices and e-way bills are generated on the government portals. The app covers regular GST invoicing, which is what most small businesses need.
Yes. Add your UPI ID once and every invoice shows a UPI QR code with the amount filled in. You can also share the invoice summary on WhatsApp.
