What invoices are included

The GSTR-1 report includes all sale invoices (type = sale, documentType = invoice) where:

• The invoice date is within the selected month and year
• The invoice status is not cancelled

Excluded:

• Cancelled invoices
• Purchase invoices
• Quotations, proformas, delivery challans (non-invoice document types)

Note

Draft invoices are included in the GSTR-1 report if their date falls within the reporting period. If you have draft invoices that should not appear in the report, either change their date or cancel them before generating the report.

Frequently asked questions

I filed GSTR-1 but then found a mistake. Can I amend it? GSTR-1 amendments are handled on the GST portal directly. Correct the invoice in Hisaabo, re-generate the GSTR-1, and use the amended figures when filing your next month’s return or an amendment return on the portal.

Why is my total in Hisaabo’s GSTR-1 different from my GSTR-2A/2B on the portal? GSTR-2A/2B reflects your suppliers’ filings, not your own. The discrepancy is normal if your suppliers are yet to file or if there are timing differences. Hisaabo’s GSTR-1 only covers your outward supplies.

A large B2C invoice is not appearing in B2CL. Why? Check that the party’s state code is different from your business’s state code (it must be inter-state) and that the party has no GSTIN (unregistered). Also confirm the invoice total exceeds ₹2,50,000.
