Payment errors happen in every business. A decimal point in the wrong place. A payment sent to the wrong vendor. An outdated invoice amount used by mistake. These small errors can cause big headaches for everyone involved.
A properly written apology email helps smooth things over when payment mistakes occur. The best apologies clearly state what went wrong, how you plan to fix it, and steps you’re taking to prevent future errors. This honest approach helps maintain good business relationships despite the mistake.

I need to let you know about a payment error we just discovered. Last Tuesday, we paid $2,300 to your account, but the correct amount should have been $3,200.

We have updated our payment templates to clearly mark the correct currency for all future transactions.
