Sales invoices (manual and uploaded)

What it is

Your shop's orders get their tax invoice automatically when you mark them shipped. For a sale made any other way — a B2B order, a counter sale, a WhatsApp deal — raise the invoice here. It is numbered in your own series (prefix in Settings, e.g. INV/2026-27/0001), posted to the books, and printable.

Steps

1. Accounting → Sales invoices → New invoice. Pick the customer (add one under Parties if needed), the date, and the place of supply if it differs from the customer's state.
2. Add lines: description, HSN/SAC, quantity, rate before GST, discount, GST rate. The total rounds to the rupee; the round-off goes to its own account.
3. Issue invoice. Open it to print or save as PDF; record the payment from the same page when it arrives.
4. Credit note / debit note: from the invoice page. A credit note lowers what the customer owes (goods returned, price cut); a debit note raises it. Both are in GSTR-1.
5. Upload an invoice made elsewhere: attach the PDF or photo, type the printed number and the lines. It joins your registers and returns; the file is the document.

Good to know

• A number, once issued, is final. Cancel with a credit note; nothing is deleted.
• A B2B invoice (customer with a GSTIN) prints the buyer's GSTIN and goes to table 4 (B2B) of GSTR-1.
• If your own GSTIN is missing, the document says "unregistered seller": set it under Settings → General → Tax.
