Capabilities

Tools 11

check_receipt_allocation

Checks how bank receipts are allocated to export invoices: arithmetic, duplicate allocations, missing row references, overallocated receipts and invoice balances. Takes anonymous row numbers and integer INR paise only; names, GSTINs and certificate numbers are not needed. Up to 200 invoices, 200 receipts and 1000 allocations.

Discovered
explain_upload_error

Returns the documented checks and correction steps for one known problem with a Statement 3 or Annexure B file. Statement 3 issues: json_generation, receipt_allocation, corrected_retry, return_mismatch. Annexure B issues: duplicate_document, gstr2b_mismatch, reversals, json_generation.

Discovered
generate_annexure_b

Creates the Annexure B JSON (statement of inward-supply invoices) for a GST refund of accumulated ITC (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, from records that pass validate_annexure_b. Returns openUrl, a link the user opens in a browser to sign in by email, pay once per GSTIN and refund period, and download; the checked records are stored behind the link for 24 hours. With a connected account that has paid, it returns the file. The tool takes no GST portal password or OTP. ITC eligibility, reversal amounts and GSTR-2B periods come from the taxpayer's reviewed records; the tool does not infer them.

Discovered
generate_statement3

Creates the Statement 3 JSON for a GST refund of accumulated ITC on exports without payment of tax (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, from records that pass validate_statement3. Returns openUrl, a link the user opens in a browser to sign in by email, pay once per GSTIN and refund period, and download; the checked records are stored behind the link for 24 hours. With a connected account that has paid, it returns the file. The tool takes no GST portal password or OTP.

Discovered
get_annexure_b_requirements

Returns the fields of the Annexure B JSON (statement of inward-supply invoices) for a GST refund of accumulated ITC (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, and where each value comes from: purchase documents, tax amounts, the GSTR-2B period, reviewed ITC eligibility and the eight GSTR-3B reversal totals, with the fields each supply type leaves empty. Takes no input. Use it before validate_annexure_b to learn which fields to collect.

Discovered
get_refund_checklist

Returns the records to gather, the checks to make, the next step and the relevant guides for one stage of a service-export GST refund claim and one preparation topic. Use it when someone asks what to prepare or check.

Discovered
get_statement3_requirements

Returns the fields of the Statement 3 JSON for a GST refund of accumulated ITC on exports without payment of tax (RFD-01), the file the GST portal otherwise requires from its Excel offline utility, and where each value comes from: export invoices and notes, bank BRC/FIRC rows, and shipping details for goods. Takes no input. Use it before validate_statement3 to learn which fields to collect.

Discovered
read_refund_guide

Returns one public guide as Markdown, with its source links and the date its sources were checked. Takes a slug from search_refund_guides.

Discovered
search_refund_guides

Finds Fast GST Refund's public guides by preparation topic and returns their slugs, titles and descriptions. Takes general keywords; it does not need taxpayer identifiers or document contents.

Discovered
validate_annexure_b

Checks records for the Annexure B JSON (statement of inward-supply invoices) for a GST refund of accumulated ITC (RFD-01), the file the GST portal otherwise requires from its Excel offline utility. Applies the offline utility's own checks and returns every error and warning at once, with its row and field. Free; needs no sign-in; stores nothing. A file made by the official utility can be passed as data unchanged. ITC eligibility, reversal amounts and GSTR-2B periods come from the taxpayer's reviewed records; the tool does not infer them.

Discovered
