Your invoices,
already sorted
into GSTR-1.
Every invoice lands in the right return table — B2B, B2CS, B2CL, exports, credit notes — and GSTR-3B summarises itself. Export what the portal (or your CA) needs, on time.
A month of invoices,
filed on time.
Your sent invoices stack up over the month, sort themselves into the five GSTR-1 tables, summarise into GSTR-3B, and export as a portal-ready file — days before the 11th.

Every invoice,
into its right table.
Your invoices already carry their GST treatment. HourSlip reads each one and routes it to the correct GSTR-1 table — registered, small, large, export or credit note — with the count and value tallied per table.
No spreadsheet, no manual sorting. The table classification a CA does by hand at filing is already done — ready to export as portal JSON.
GSTR-3B,
summarised.
The summary return fills itself from your GSTR-1 figures and your input credits. Outward tax, reverse-charge, eligible ITC and net payable — all computed, all reconcilable before you submit.
3.1(d) reverse charge — GST you owe on certain inward supplies (a lawyer's fee, an import of services). We surface it explicitly so it never gets left off.
| § | Nature | Taxable | Tax |
|---|---|---|---|
| 3.1(a) | Outward taxable supplies | ₹15,28,000 | ₹2,75,040 |
| 3.1(d) | Inward supplies · reverse charge (RCM) | ₹1,00,000 | ₹18,000 |
| 4(A) | Eligible input tax credit (ITC) | — | − ₹74,200 |
Monthly or quarterly —
your filing calendar.
Most freelancers under ₹5 crore pick QRMP — quarterly returns, monthly tax. HourSlip knows your scheme, marks every due date, and reminds you days before each one so you never pay a late fee.
Composition scheme?
GSTR-4 instead.
On the composition scheme you don't file GSTR-1 or 3B — you pay a flat rate and file once a year. HourSlip detects your scheme and switches the whole flow automatically: Bill of Supply, no tax line, annual GSTR-4.
GSTIN validation +
e-invoicing awareness.
A wrong GSTIN gets your return rejected at the portal. HourSlip validates the checksum and state code as you type — and tracks your FY turnover so you know the moment e-invoicing becomes mandatory for you.
Free to validate.
Pro to file the lot.
The free GSTIN validator keeps your data clean. Pro assembles GSTR-1, summarises GSTR-3B, handles composition GSTR-4, runs your filing calendar, and tracks your e-invoicing threshold.
An honest
side-by-side.
Refrens, Zoho and ClearTax are genuinely excellent at GST — we won't pretend otherwise. The honest edge here isn't a missing feature; it's that the returns are built from invoice data you already have, in a tool shaped for one freelancer, not an enterprise suite you configure.
Returns, demystified.
What freelancers and their CAs ask about GST filing before they switch.
- HourSlip assembles a filing-ready return — every GSTR-1 table, the GSTR-3B summary, validated GSTINs — and exports it as portal JSON/CSV. You or your CA upload and submit on the GST portal; the final submission stays in your hands.
- By who the buyer is and where they are. Registered buyers go to B2B; small unregistered in-state to B2CS; large inter-state unregistered to B2CL; exports to EXP; credit/debit notes to CDNR. Each invoice already carries its GST treatment, so routing is automatic.
- Under ₹5 crore turnover you can opt into QRMP — file GSTR-1 and 3B quarterly while paying tax monthly via PMT-06. Above that, or by choice, you file monthly. HourSlip knows your scheme and marks the right due dates with reminders.
- Yes. If you're registered under composition, HourSlip switches the entire flow — Bill of Supply with no tax line, flat 1%/6% rate, CMP-08 quarterly and the annual GSTR-4 — automatically, instead of GSTR-1/3B.
- Yes, and we surface it explicitly. Reverse-charge GST on certain inward supplies belongs in GSTR-3B row 3.1(d) — a line freelancers routinely miss. HourSlip flags applicable expenses and fills the row.
- HourSlip tracks your FY aggregate turnover and alerts you as you approach the ₹5 Cr threshold where e-invoicing becomes mandatory. You generate the IRN on the NIC / IRP portal (or via your GSP), then paste it onto the invoice in HourSlip — it stores the IRN, Ack-No and date and prints them on the PDF. Direct IRP API integration is on the roadmap.
Your GSTR-1
is already done.
You sent the invoices. The return assembles itself from them — sorted, summarised, validated. All that's left is to export the file and file it. On time, every month.
