GSTR-1 Report

GSTR-1 is the monthly return you file with the GST portal listing all your outward supplies (sales). Hisaabo generates this report automatically from your invoice data.

Generating the report

1. Click GST in the left navigation.
2. Select GSTR-1 from the tabs.
3. Choose the Year and Month.
4. Click Generate.

The report loads immediately — it is computed in real time from your invoice data. There is no caching, so it always reflects the latest state of your invoices.

Your CA will ask for this report every month. Generate it, click Export CSV, and email or WhatsApp the file — they’ll take it from there. You don’t need to understand every section below; skip to Filing workflow if you just want the handover checklist.

Before you file

Two sanity checks before exporting: (1) confirm no invoices are still in draft status for the period — drafts are counted in the report and are the most common source of post-filing amendments, and (2) spot-check a B2B row against the original invoice PDF for GSTIN and taxable value accuracy.

Report sections

B2B — Outward supplies to registered persons

This section lists every sale invoice to a party that has a GSTIN in Hisaabo.

One row per invoice. Intra-state invoices have CGST and SGST values; inter-state invoices have an IGST value.

Exporting as CSV

Click Export CSV to download the report as a comma-separated values file named GSTR1_Apr_2025.csv (month and year in the filename).

The CSV includes all sections (B2B, B2CS, B2CL, HSN summary) separated by blank lines and section headers.

To upload to the GST portal:

1. Download the CSV from Hisaabo.
2. Open the GST Offline Utility (available from the GST portal).
3. Import the CSV (or manually enter the data from the CSV into the utility).
4. Validate and generate the JSON file.
5. Upload the JSON to the GST portal.

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.
