GSTR-1 software built around how Indian CAs file
GSTR-1 is the outward-supply return every regular GST dealer files monthly or quarterly. Our GSTR-1 software reads every sales invoice, credit note, debit note and advance receipt of the period and groups them into the exact tables the GST portal expects — B2B (4A), B2C-Large (5A), B2C-Small (7), HSN summary (12), Documents (13) and more.
You can review the prepared GSTR-1 line-by-line, fix mismatches with one click, and either upload the JSON to the GST portal or push it via GSP. QRMP quarterly filers get the IFF flow for the first two months and the full GSTR-1 for the quarter.
