Check every supplier invoice against its PO before you pay.
Add the invoice to its purchase order and Expeni compares the two. An invoice above the PO is held until the approver accepts the difference.

Questions about invoice matching
Is this three-way matching?
Expeni compares the invoice with the purchase order. Goods received are recorded on the same PO, so finance can check them side by side before paying, but the invoice is not compared with the receipts automatically.
What happens when an invoice is higher than the PO?
The invoice is held, and the PO approver is asked to approve the difference. It can only be paid once the difference is approved.
Can one invoice cover several purchase orders?
Yes, when they are from the same vendor. You can also add invoices that have no purchase order.
Does Expeni pay the supplier?
No. You pay as you do today, from your bank or accounting system, and record the payment in Expeni. The PO then shows unpaid, partially paid or paid.
