File GSTR-1 & GSTR-3B
without the spreadsheet.

Every bill you raise in SoloBooks already carries the GST detail your returns need. Here is how that rolls up into GSTR-1 and GSTR-3B.

GSTR-1 vs GSTR-3B

GST filing in India centres on two returns. GSTR-1 reports your outward supplies — every sales invoice, broken down by GSTIN, taxable value, and tax rate. GSTR-3B is the summary return: total taxable turnover, output tax, input tax credit claimed, and the net GST you pay for the period.

GSTR-1

Invoice-level detail of all outward supplies. Drives your customers' input tax credit, so accuracy matters.

GSTR-3B

Period summary of output tax, input credit, and net liability. This is what determines how much GST you actually pay.

How SoloBooks builds your returns

Because every bill posts a balanced double-entry journal with the right tax ledgers, SoloBooks can aggregate the period for you. Intra-state sales split into CGST + SGST; inter-state sales use IGST. The report rolls taxable value and tax up per rate slab, ready to reconcile against the GST portal.

Good to know

SoloBooks reports follow the Indian financial year (April 1 – March 31). Quarters are Apr–Jun, Jul–Sep, Oct–Dec, and Jan–Mar — matching the periods you select on the GST portal.

At filing time

Open Reports → GST, pick your return period, and review the GSTR-1 and GSTR-3B summaries. Use them to file on the GST portal yourself, or hand them — along with a one-click Tally export — to your Chartered Accountant.

FAQ

GST filing — common questions

What is the difference between GSTR-1 and GSTR-3B?

GSTR-1 is a detailed return of your outward supplies (sales), reported invoice by invoice. GSTR-3B is a summary return where you declare total taxable value, output tax, input tax credit, and the net GST payable for the period. Most businesses file both.

Does SoloBooks file GST returns directly with the GST portal?

SoloBooks prepares GSTR-1 and GSTR-3B summaries from your billing data so you or your CA can file accurately on the GST portal. It organises taxable value and CGST/SGST/IGST totals; the final submission is made on the government portal.

How does SoloBooks decide between CGST/SGST and IGST?

SoloBooks applies CGST and SGST (a 50/50 split) for intra-state supplies, where the customer is in the same state, and IGST (the full rate) for inter-state supplies. This is determined automatically from the place of supply on each bill.

What is the Indian GST filing period?

GST returns are generally filed monthly or quarterly depending on your turnover and scheme. SoloBooks aligns reports to the Indian financial year, which runs from April 1 to March 31, with quarters Apr–Jun, Jul–Sep, Oct–Dec, and Jan–Mar.
