Check a short payment

Compare one invoice with its allocated cash and applicable posted credits. The result is a difference to explain, not an assessment of what can be recovered.

USD only. Enter digits with a decimal point and up to two decimals, such as 12000.00. No commas, symbols or conversion. Each amount must be from 0 to 999999999.99; enter 0 explicitly when none applies.

The interactive check needs JavaScript. Use the formula below and the deduction evidence worksheet for a manual check.

One invoice, one currency
What does the invoice amount you will enter already include?

Pick the line that matches your figure so nothing is subtracted twice. Changing the basis clears the invoice amount and credits so you can verify them.

Use this invoice’s allocation, not the total remittance for several invoices.

Include only posted credits applicable to this invoice, not proposed, disputed or unapplied credits. Enter 0 if none.

Enter amounts or fill the synthetic example.

The check calculates amounts in your browser and keeps them in page memory. Reset or leave this page to clear the working state. The optional download saves a file on your device. No invoice identifiers or files are needed.

How to read the result

Unexplained difference = entered invoice amount − cash not already applied − applicable posted credits not already included.

A gross amount subtracts both. A balance after credits subtracts cash only. A balance already net of cash and credits subtracts nothing, so a payment is never taken out twice. Cash is subtracted only after you confirm that the entered amount has not already been reduced by it; without that confirmation the check asks for clarification instead of reporting a difference. The confirmation prevents an unconfirmed subtraction; it cannot verify that the basis you chose is true. A positive difference needs an explanation. Zero reconciles only these inputs; it does not prove acceptance or closure. A negative difference flags excess entered cash or credits for an allocation/input check.

Match the records with the short-pay reconciliation guide and deduction evidence worksheet. Agreement applicability, other adjustments and entitlement require separate review.
