Use amount-based matching of purchase orders to match supplier invoices for services based on the invoice amount. Purchasing specifies Amount as the match basis.

You can perform amount matching on the following kinds of invoices: Credit Memo, Debit Memo, Expense Report (from Invoice Workbench only), Mixed, Prepayment, Recurring, and Standard.

When matching invoices based on amount, match your billed (invoice) amount to purchase order shipments or receipts to ensure that you pay only for the rate or value of the services. You enter invoices and create invoice distributions similar to quantity matching. However, you provide an amount, rather than quantity and unit price, as the basis to create distributions.

You can further match a distribution to a purchase order by clicking on the Distribute button, selecting each purchase order distribution, and entering the applicable amount. If you have not distributed while selecting a shipment, Payables prorates the appropriate purchase order distribution.

In some instances, you may enter an invoice against a service shipment with different rates for regular and overtime hours. If you want to match to the service shipment and also track the regular and overtime hours differently, you match to the same shipment twice and enter the appropriate amount each time. You can optionally enter the hours worked in the Quantity Invoiced field and the rate in the Unit Price field.

You can also allocate charges during matching by specifying the tax, freight, and miscellaneous charges.

Invoice validation is similar to quantity matching except if the accrue on receipt option is set to No, Payables calculates the amount variance, which is the excess amount invoiced and expensed during accounting. Payables does not have a separate accounting entry for this but records it separately for encumbrance.

In addition to the entries recorded by Payables in encumbrance accounting, Payables creates amount variance encumbrance entries if the PO and Invoice Encumbrance types are different and reverses any amount variance during invoice accounting in accrual basis and during payment accounting in cash basis.

Since quantity-related and price-related validations are not applicable, Payables does not check tolerances related to quantity and price. Invoice tolerances specified for the quantity and price are also not applicable. Instead, Payables validates the invoice only on the following applicable holds when matched to a service order or receipt: Final Matching, Currency Difference between Invoice and PO, PO Approval, Receipt Exception, Shipment Exception, Shipment Amount, Total Amount, and Exchange Rate Amount.
