Duplicate Vendor Payment Applied to Open Invoices in Acumatica

Hello Community,

We made duplicate payments for two invoices, and the vendor has already cashed both checks.

What would be the best way to handle this in Acumatica? We would like to apply the duplicate payments as credits toward the vendor’s open invoices instead of requesting a refund.

Thank you,

Hello ​@amelendez ,

Enter each extra Payment as a Debit Adjustment. Debit Adjustments debit the AP account and reduce the amount owed to a vendor.

Select the Dbit Adjustments along with new bills on the next check, to reduce the amount paid to your vendor.

@Laura03 - I appreciate your response; this makes sense. I was just hesitant because I wasn’t sure whether processing the duplicate payment this way would create an unnecessary credit entry or cause the vendor account to appear out of balance. this is perfect. thank you!
