The problem

Manual invoice reconciliation is slow and error-prone

Accounts payable teams compare invoices with purchase orders and receipts line by line. Vendors describe the same item differently, prices drift, and duplicates slip through.

Three-way match

Invoice quantities are checked against the order and the receipts, and prices against the order, with your tolerances.

Line matching

Lines are paired by SKU or line ID first, then by description when wording differs, such as "Gloves, nitrile, L" and "Nitrile gloves, large".

Arithmetic and duplicates

Line amounts, subtotals, and totals are recomputed exactly. Duplicates are flagged against invoices you supply.

Use cases

Where teams use it

Accounts payable
Three-way match
Procure-to-pay platforms
Duplicate invoice detection
Spend management

Limitations

One purchase order per request, and no currency conversion.
Duplicates are detected only against invoices you supply.
Advisory: it recommends a next step and never pays or approves.
