Receive Short Payment > Create Deductions Claim > Review & Research Claim > Create & Apply Credit Memo or Overpayment This is the correct sequence of steps to create a claim for a short payment.A short payment is a payment that is less than the invoice amount due to various reasons, such as discounts, allowances, or disputes1.To create a claim for a short payment, you need to follow these steps2:
* Receive Short Payment: You receive the payment from the customer and apply it to the invoice partially. This creates an open balance on the invoice.
* Create Deductions Claim: You create a claim for the difference between the invoice amount and the payment amount. You can specify the reason and the justification for the claim, and attach any supporting documents.
* Review & Research Claim: You review the claim and research the cause of the short payment. You can contact the customer or the internal departments to verify the validity of the claim and resolve any issues.
* Create & Apply Credit Memo or Overpayment: You create a credit memo or an overpayment to close the open balance on the invoice and settle the claim. A credit memo is a negative invoice that reduces the amount owed by the customer. An overpayment is a payment that exceeds the invoice amount and can be applied to future invoices.
