We value your time doing business with us, @tsd81.

While customer's overpayment isn't automatically created as a credit memo, I can pass along your feedback to our product developers.

This way, they'll be able to know your sentiments and needs for product enhancements.

They can consider adding this feature for future product updates that can greatly help other users like you.

Please let me know in the comment section below if you have any other questions. I'll be always around here in the Community ready to help.
