E-invoice & E-way Bill Reconciliation: Match the IRN to the Movement
Dynamite Docs Team — 2026-08-14
Two documents, one transaction
An e-invoice is a GST invoice verified through the e-invoice system and identified by its IRN. An e-way bill is the document for movement of goods, carrying the supplier, buyer, the invoice reference, the goods value, and the transport details. They are not the same document, but they describe the same transaction: one purchase, its electronic record, and the movement that carries it.
Reconciliation means keeping those three aligned. The invoice you hold, the e-invoice IRN, and the e-way bill should agree on supplier GSTIN, buyer GSTIN, document reference, and goods value. When they disagree, the difference usually hides a real problem, a wrong GSTIN, a value that changed, a movement someone cannot account for.
- The IRN ties the invoice to the electronic record
- The e-way bill records how the goods moved
- Both should agree with the invoice on GSTIN, reference, and value
What has to match
The fields that must line up are few and exact: the supplier and buyer GSTINs, the document number and date the movement refers to, the goods value, and, where the goods are transported, the vehicle and transporter. The IRN is captured as a field of its own, not buried in a page corner, and on an e-way bill the Part A and Part B halves come out as one row, references and transport details together.
Extraction reads both documents into the same schema, so the comparison runs on rows. A transposed digit in a GSTIN or a reference that does not match the invoice stands out immediately instead of hiding in a PDF. Digital e-invoice PDFs parse deterministically; QR screenshots, scanned e-way bills, and WhatsApp forwards are read by the vision model you choose.
- Supplier and buyer GSTIN, document reference, goods value, vehicle
- The IRN captured as its own field on e-invoices
- Part A and Part B of the e-way bill in one row
The match runs on rows; the decisions stay with your team
Export the extracted e-invoice and e-way bill rows to Excel, CSV, or JSON, or push them to Google Sheets, and reconcile the month’s movements against the invoices in the same workspace. Corrections are remembered per transporter and per supplier, so repeat documents extract cleanly after the first review.
Validation against portal records, and decisions about what current rules require for a movement, stay with your team and your compliance process. Dynamite Docs is a document-processing and data-preparation layer; consult the GST portal and your tax advisor for the rules that apply to your supplies.
Keep document data off models you didn’t choose
E-invoices and e-way bills carry supplier, buyer, and movement data that is not content for a model you did not approve. Bring your own keys on every plan and pay your provider’s rate with zero markup; on Pro and Ultra that BYOK processing is unlimited and never counts against your monthly allowance. Documents are encrypted at rest, never used to train foundation models, and sensitive processing can be locked to no-training providers or run fully local with Ollama.
