GSTR-1 PREPARATION SOFTWARE

GSTR-1 preparation software for Indian businesses

Generate and review GSTR-1 from your sales register, then download GSTN-format JSON plus an Excel review workbook. Complete GST portal validation, payment, and filing manually; record the ARN afterward. Free plan available.

Supported GSTR-1 workflow

Supported GSTR-1 sections are populated from your books for review.

Supported GSTR-1 sections

B2B, B2C-Large, B2C-Small, exports (with and without payment of tax), credit / debit notes, HSN summary, and the document-issued table are populated from your sales register for review.

GSTN-format JSON export

Review the generated return, download GSTN-format JSON plus an Excel review workbook, upload the JSON and complete validation, payment, and filing on the GST portal, then record the ARN in ReadyBooks.

GSTN-format JSON export

Generate JSON in the GST portal schema for manual upload. The same return data is also available in an Excel review workbook.

GSTIN + place-of-supply validation

Every invoice is validated against GSTIN format (check-sum, state code, PAN consistency) and place-of-supply rules before it reaches the return. Catch errors before download and portal upload.

Amendment support (9A, 9B, 9C)

Edit a prior-period invoice and the change routes to the right amendment table automatically. Review the updated return before downloading the next GSTN-format JSON export.

HSN summary with rate-wise breakup

HSN table aggregated from your item master. JSON generation fails closed when a required HSN is missing. A reviewer selects the applicable 4- or 6-digit minimum for the exact period before download.

Why CAs and Indian SMBs use ReadyBooks for GSTR-1

Built for the exact GSTR-1 workflow Indian CAs run.

Sales-register generation

GSTR-1 is assembled from your sales register. Review the generated return, download GSTN-format JSON plus an Excel review workbook, and complete the GST portal steps yourself.

Recipient details stay reviewable

Review GSTIN, place of supply, invoice values, and tax heads before portal upload. Recipient GSTR-2B availability and timing depend on GST portal processing and remain outside ReadyBooks.

QRMP quarterly preparation

Prepare and review the supported quarterly GSTR-1 sections, then download the exact-quarter JSON or Excel artifact. IFF and PMT-06 are not submitted or tracked by this workflow.

CA-firm friendly

Multi-client dashboard for CA firms. Review and export GSTR-1 for each client with a separate audit trail before the manual GST portal steps.

Built for Indian GSTR-1 reality

GSTR-1 reports outward supplies. Data accepted and processed by the GST portal can feed recipient-facing return views, but portal processing and recipient credit eligibility are outside ReadyBooks. Review every buyer and tax detail before upload.

ReadyBooks.ai treats GSTR-1 as a first-class reporting workflow. Supported outward-supply sections are assembled from the books, and portal JSON generation fails closed when a required field such as a valid GSTIN, HSN, date, or place of supply is missing. The GST portal remains the final validation authority.

How GSTR-1 preparation and portal handoff works inside ReadyBooks.ai

The GSTR-1 module reads from your sales register. Sales invoices, debit notes, and credit notes are mapped to the applicable GSTR-1 table based on buyer registration status, invoice value, place of supply, and document type. Review the assembled return before export.

The GSTR-1 dashboard shows the count of invoices in each supported section together with taxable value, CGST, SGST, and IGST. Review those figures before export. JSON generation stops with an error if a required portal field cannot be produced; after correcting the source record, download GSTN-format JSON plus an Excel review workbook. GST portal validation, payment, and filing remain required.

After you file on the GST portal, record the ARN (Acknowledgement Reference Number) and filing timestamp against the return in ReadyBooks. The product keeps the preparation and evidence trail together without claiming to submit the return for you.

GSTR-1 vs IFF vs GSTR-3B — what files when

Monthly GSTR-1 and GSTR-3B figures should be reviewed together before portal filing. ReadyBooks prepares each supported report from the books, but it does not currently claim an automatic GSTR-1-to-GSTR-3B reconciliation. Confirm the applicable cadence, due date, and portal validation results on the GST portal.

For tenants configured for QRMP, ReadyBooks prepares the supported quarterly GSTR-1 and GSTR-3B views and downloads. IFF, PMT-06, payment, validation, and filing remain GST-portal steps outside this workflow.

GSTR-1A is a recent addition (2024) that lets you amend an in-month GSTR-1 before filing GSTR-3B. Use the GST portal's GSTR-1A process for that portal-side amendment after reviewing the source data in ReadyBooks.

Common GSTR-1 mistakes ReadyBooks.ai prevents

Wrong place of supply on a B2B invoice — a common cause of disputes where the buyer's ITC is denied because of intra-state vs inter-state mismatch. ReadyBooks.ai compares your business state, buyer state, and place of supply at entry and rejects the invoice if the combination is invalid.

Large inter-state invoices issued to unregistered buyers (over ₹2.5 lakh before 1 Aug 2024 and over ₹1 lakh from 1 Aug 2024) reported under B2CS instead of B2C-Large. ReadyBooks.ai routes these based on the invoice date and value, buyer registration, and place of supply.

Missing HSN in an outward-supply line. The portal JSON generator rejects a required missing HSN instead of substituting a code; correct the item or line and generate the file again.

Credit notes routed to the wrong table — CDNR is for registered buyers, CDNUR for unregistered. Manual filers often mix them up. ReadyBooks.ai picks the right table from the buyer's GSTIN status at the time the credit note was issued.

GSTR-1 filing scenarios we handle every month

Solo CA, 25 clientsGSTR-1 filing window on the 11th means 25 client returns need review and portal upload in 3 working days.

The CA dashboard shows pending status across clients. Open each client to review the return figures and generate the supported JSON for manual portal upload. GST portal validation, payment, and filing remain required for each client.

Garment exporter, SuratMix of B2B domestic, B2C, and exports with-and-without IGST payment — easy to misroute lines.

Export invoices marked zero-rated flow to the right table. Domestic B2B and B2CS are populated from the same sales register. HSN summary picks up textile codes correctly. Download the reviewed file for one manual portal handoff.

QRMP filer, ₹3.2 crore turnoverBuyers complain their ITC is delayed because of quarterly GSTR-1.

ReadyBooks keeps the quarterly preparation and due-date context together. Review the B2B data, then complete any IFF or quarterly GSTR-1 upload directly on the GST portal.
