What is 3-way matching?

Checking an invoice against the purchase order and the goods receipt before payment, so you pay only for what was ordered and received, at the agreed price.

Does it handle GST e-invoices?

Yes. It reads GSTIN, HSN or SAC codes and the IRN, and checks them against the supplier master and the purchase order.

Invoices matched, coded and queued for approval, and reconciliations proposed with reasons

Finance operations agents read supplier invoices from email and portals, match them to the purchase order and goods receipt, code the GL account and cost centre with your rules, check tax fields such as GST, and queue clean invoices for approval. Mismatches go to an exception queue with the reason. Reconciliation agents propose bank, ledger and vendor-statement matches with the evidence. People approve every payment.

Who owns the mistake? The approver who holds that authority today. The agent prepares and proposes; it can't release a payment or post an entry.

Fair questions

What people ask before they trust it.

We already have an AP suite.: Keep it. We build the part the suite leaves to people: your exception rules, your ERP's quirks, supplier statements in odd formats and the reconciliations at month end.
Can an agent move money?: No. It prepares and proposes. Payments and postings are approved by the people who hold that authority today, and every step is logged.
