GST Compliance Overview

Hisaabo is designed to make GST compliance as automatic as possible. This page gives you an overview of how GST flows through the system from invoice creation to report generation.

How GST is calculated on invoices

See GST on Invoices for the full explanation. In summary:

1. You set a tax rate (0%, 5%, 12%, 18%, or 28%) on each item.
2. You set your business’s 2-digit state code in Settings.
3. You set each party’s 2-digit state code on their party record.
4. When you create an invoice, Hisaabo compares state codes to determine CGST+SGST (same state) or IGST (different states).

GST report generation

Hisaabo generates two key GST reports: GSTR-1 and GSTR-3B. Both are computed from your invoice and payment data — there is no manual data entry into the reports.

Reports cover outward supplies (sales) for GSTR-1 and both outward (sales) and inward (purchases) supplies for the ITC calculation in GSTR-3B.

Note

GST reports are available for all businesses — both GST-registered and unregistered. For unregistered businesses, the reports show total sales and purchase figures without GST breakdown. For registered businesses, full CGST/SGST/IGST splits are shown.

GSTR-1

GSTR-1 is the monthly return for outward supplies (sales). Hisaabo generates it with the following sections:

Section	What it contains
B2B	Sale invoices to GST-registered parties (parties with a GSTIN)
B2C Large	Inter-state sale invoices to unregistered parties exceeding ₹2.5 lakh
B2C Small	Intra-state and small inter-state sales to unregistered parties, aggregated by tax rate
HSN Summary	Total quantity and value sold, broken down by HSN code
Credit Notes	Credit note documents issued during the period
Debit Notes	Debit note documents issued during the period

See GSTR-1 for detailed instructions.

GSTR-3B

GSTR-3B is the monthly summary return. Hisaabo generates:

Section	What it contains
3.1 Outward Supplies	Total taxable value and tax broken down by IGST, CGST, SGST
3.2 Inter-state to unregistered	State-wise IGST on large inter-state B2C supplies
4 ITC (Input Tax Credit)	GST paid on purchase invoices
Tax Payable	Total output tax (from sales)
Net Tax	Tax payable minus ITC = tax you owe to the government

CSV export

GSTR-1 can be exported as a CSV file formatted for upload to the GST portal. Each section (B2B, B2CS, etc.) is exported as a separate section within the CSV.

To export: open the GSTR-1 report for the desired month and click Export CSV.

Current limitations

• Exports are in a generic CSV format. The official GST portal requires JSON upload or the offline utility. You may need to reformat the CSV before uploading.
• Zero-rated supplies (SEZ, export of goods) are not separately tracked — they appear as regular inter-state supplies.
• Composition scheme dealers do not have GSTR-4 generation. Composition businesses can use Hisaabo for record-keeping but must prepare their GSTR-4 manually.
• The HSN summary uses HSN code 0000 for line items where the item does not have an HSN code set.

Filing workflow (recommended)

1. At the end of each month, open GST in the left navigation.
2. Select the month and year, then view the GSTR-1 report.
3. Verify the totals match your expectation. If an invoice is missing, check that it is not in cancelled status — cancelled invoices are excluded from reports.
4. Export the GSTR-1 CSV.
5. Use the GST Offline Utility or your CA’s software to prepare the final filing from the CSV.
6. File GSTR-1 on the GST portal by the 11th of the following month.
7. Review the GSTR-3B report for your ITC and net tax payable calculation.
8. File GSTR-3B and pay any tax due by the 20th of the following month.

Frequently asked questions

My GSTIN is not showing on the invoice PDF. What is wrong? Go to Settings → Business Profile and confirm that:

1. Your GST Registration Type is set to “Regular” or “Composition” (not “Unregistered”).
2. Your GSTIN is entered correctly in the GSTIN field.

A sale invoice is not appearing in the GSTR-1 report. Why? Cancelled invoices are excluded from all GST reports. Check the invoice status. Also check that the invoice date falls within the reporting period and that the document type is “invoice” (quotations and delivery challans are not included in GSTR-1).

How do I handle invoices for the previous month that I created this month? GSTR-1 uses the invoice date, not the creation date. If you create an invoice today but set the invoice date to last month, it will appear in last month’s GSTR-1 report.
