Dynamite Docs extracts draft fields and line items from Indian GST invoices for source review and spreadsheet preparation. Use it to collect supplier and buyer GSTINs, invoice references, printed HSN/SAC codes, taxable values, and tax amounts. The result is a starting table for a tax professional’s working papers.
Keep sales invoices, purchase invoices, credit notes, and debit notes distinguishable. A source document’s printed tax treatment may need further investigation. Extraction preserves what the document says; it does not decide the correct tax treatment, credit eligibility, or return classification.
Documents to prepare
Sales invoice registers
Capture invoice number, date, buyer identifier, taxable value, currency, and printed tax splits. Preserve adjustment-note references so the reviewer can trace changes to the original invoice.
Purchase invoice working rows
Keep supplier GSTIN, invoice reference, line descriptions, and separate CGST, SGST, IGST, and cess values where printed. Do not create an absent tax amount from an assumption.
Scanned invoice exceptions
Check faint identifiers and decimal points beside the scan. If the source is cropped or unreadable, request a replacement instead of accepting a plausible model answer.
An illustrative Indian GST invoice working row
Fictional arithmetic and masked identifiers. The example demonstrates separate columns and is not advice about an applicable tax rate.
| Invoice | Supplier GSTIN | Taxable value | CGST | SGST | IGST | Total |
|---|---|---|---|---|---|---|
| DEMO-101 | Masked for example | 1000.00 | 90.00 | 90.00 | 1180.00 | |
| DEMO-CN-02 | Masked for example | -100.00 | -9.00 | -9.00 | -118.00 |
Review against the source
- Compare supplier and buyer identifiers character by character and keep their roles separate.
- Preserve the full invoice number, date, note type, currency, and any reference to an earlier invoice.
- Compare printed taxable values and tax amounts with line items and totals; investigate rounding or inconsistent arithmetic.
- Review return classifications and any external matching in your tax workflow after the source extraction is checked.
Prepare a reviewed handoff
Separate the document groups
Choose purchase, sales, or adjustment documents for the first run. Extract printed fields into a consistent schema before adding tax-working classifications.
Check identifiers and amounts
Review GSTINs, HSN/SAC codes, dates, line values, and tax splits beside the original. Keep unresolved exceptions visible for the professional reviewing the records.
Map reviewed data into working papers
Export accepted rows to Excel or JSON. Apply your return-preparation mapping in the receiving system and reconcile record counts and totals before use.
Use the accepted output
Excel provides a reviewed invoice register with separate tax columns and exception notes. JSON provides fields and line items for a controlled mapping. Neither output is a filed GST return or proof that an invoice qualifies for input tax credit.
Processing choices and allowances
Choose hosted AI, your own provider keys, or local Ollama on an eligible plan. Each successfully processed hosted page uses one PE. Free and Hobby BYOK use the same PE allowance; Pro and Ultra BYOK cost zero PE, with provider charges and limits still applying. Failed pages cost zero PE.
Check current plans, page limits, and capabilities and review storage and data-residency policies before processing sensitive records. Local model inference is a separate choice from browser-local file storage.
Workflow boundaries
- Tax professionals determine tax treatment, return classification, and credit eligibility using current rules and supporting records.
- Dynamite Docs does not file returns, validate registrations with the GST portal, or perform portal reconciliation on this page.

Questions about this workflow
Will AI decide the applicable GST rate?
This workflow extracts printed invoice data. A qualified reviewer determines the applicable treatment and investigates any discrepancy using current official sources.
Can these rows be filed directly?
No. Review the source values, apply the receiving system’s mapping, investigate exceptions, and complete your normal return-preparation checks.
