GSTR-1 is simply the statement of your outward supplies — everything you sold in the period. If your sales are recorded cleanly through the month, filing is a download. If they aren't, month-end becomes a reconciliation marathon.
What GSTR-1 actually reports
- B2B invoices, with the buyer's GSTIN
- B2C sales, summarised
- Credit and debit notes
- HSN-wise summary of goods sold
Why mismatches happen
Almost every GSTR-1 headache traces back to messy source data: wrong GSTINs, missing HSN codes, invoices edited after the fact, or a tax split done by hand. Fix the invoice and you fix the return.
File from your sales data, not a separate spreadsheet
The cleanest workflow is to export GSTR-1 directly in the government format from the same system that raised the invoices. No re-typing into a template, no copy-paste, no version confusion.
