I need invoice help with a donation check

[Naekeisha]

How can I document on a paid invoice that a customer paid over agreed amount in a check, but she made the entire payment as a donation. Which is fine but when I went to do the transaction there was not an an option to add new amount and just tender, which cashed out for wrong amount?

I'm not sure if this will help or not, but when you select "Mark as Paid," and then select "Check," you are given the option to make a note with the sale.  As I haven't made any notes yet, I can't say for sure, but my guess is that you should be able to view that note when you view the transaction details.  Hope this helps!
