Applying payment to an invoice that is more than the invoice amount and refunding the difference.
Hi ,
We had a customer make a down payment for a project that involved graphic design.(We charge by the hour for this.)
Our designer thought it would take longer to do this job than it actually did.
We do invoicing on 60%,(they pay the rest at the time of completion) and the customer paid this before starting on the project based on the order and the 5 hour design time.
When I changed the design time from 5 hours to 1.5 hours after the job was completed, the amount of his downpayment(this was made a few weeks ago so it couldn't be deleted) ended up being more than what is actually owed so it would not let me apply the credit to the full invoice ..
What is the best way to go about fixing this so we can refund his money?
