GST returns
from your real books.

OneBooks prepares GSTR-1 and GSTR-3B from the invoices and purchases you actually issued — HSN/SAC, place-of-supply splits, reverse charge and readiness checks included — and exports them for filing.

JSON & Excel

How it works

From invoices to a return you can file.

01

Set up GST

Enter your GSTIN, choose inclusive or exclusive pricing, and set item tax rates and HSN/SAC codes.

02

Run the readiness check

OneBooks flags documents missing the data a return needs — before the deadline, not after.

03

Export and file

Download GSTR-1 and GSTR-3B as JSON or Excel and file through your portal or practitioner.

What's prepared

The return is arithmetic when the documents are right.

Every invoice and purchase carries its tax per line, so the return is assembled — not reconstructed.

  • GSTR-1 — outward supplies from your actual invoices, with HSN/SAC and place of supply.
  • GSTR-3B — summary liability and input credit, including reverse-charge treatment.
  • CGST / SGST / IGST — split correctly by place of supply for the reports.
  • Readiness checks — missing GSTINs, HSN codes or rates surfaced before export.
Why it matters

No spreadsheet marathon at month end.

Filing from re-keyed exports is where errors creep in. Filing from the documents themselves removes the step.

  • Tax control accounts tie out — what's reported equals what's booked.
  • POS sales included — output tax from connected tills flows into the same return.
  • Rupee books, Indian rates — 18% GST defaults, ₹ formatting, GSTR-ready from signup.

GST — common questions

Does OneBooks file directly with GSTN?

It prepares GSTR-1 and GSTR-3B and exports them as JSON or Excel for filing through the portal or your practitioner.

Is reverse charge handled?

Yes — reverse-charge purchases post the self-assessed tax and its input credit automatically and are reported correctly.

What are readiness checks?

Automated checks that flag documents missing GSTINs, HSN/SAC codes or rates before you export, so the return isn't rejected.

Are POS sales included?

Yes — output tax from connected point-of-sale systems flows into the same tax reports as manual invoices.
