Payment Applied to Wrong Invoice Email Template

Use this page when cash has arrived, but it was booked against the wrong invoice and your aging is now pointing at the wrong balance. This is a classic B2B collections friction point: the payer may think they already paid, while your team still sees the target invoice as open because the posting landed in the wrong place. This page is different from an unapplied-payment follow-up because the money is not missing altogether. It exists, but it is tied to the wrong document. Your goal is to get AP or finance to reallocate the payment quickly, confirm the corrected balance, and stop the collection thread from chasing the wrong problem. Used well, this page helps prevent false escalation, protects the relationship, and moves the case back into an evidence-based workflow that can either clear the invoice or identify the real remaining balance.
