GST E-Invoicing Software | E-Invoice Reconciliation
IRNs from anywhere, reconciled against your books nightly.
IRNs and e-way bills generated outside OneFinOps (legacy system, customer portal, manual GSTN portal entry) pulled from the GSTN. Reconciled against your invoice book nightly. Mismatches surface; books align with what is on the GSTN.

Compliance + integrations
Books reflect what GSTN sees.
For e-invoicing-eligible taxpayers, the GSTN view of issued invoices is authoritative for B2B. The system keeps your books aligned with that view.
Regulations we work within
-
Rule 48(4), CGST Rules

E-Invoice Reconciliation FAQ
What buyers ask.
Why would IRNs be issued outside OneFinOps?
Common cases: legacy ERP not yet integrated, customer portal that uploads invoices on behalf of supplier, manual GSTN portal entry by a back-office team. The recon catches all of these.
Missing-in-books IRN. Can we auto-post the invoice?
Yes. The system can auto-post the missing invoice from the GSTN data (invoice number, customer, amount, tax components). Posting goes through the standard approval flow.
Missing-in-GSTN. How does the system flag it?
An invoice eligible for e-invoicing (B2B, customer GSTIN present, taxpayer above turnover threshold) without an IRN is flagged. The system suggests generating an IRN at the original invoice date.
