Let me chime in and provide clarifications about crediting finance charges that have already been paid, @T4KB.
To begin with, there's no need for you to create a reimbursement or issue a credit memo because you've already deleted the Finance Charge (FC) invoice that has been paid. By deleting the FC, this will automatically turn the payments into unapplied credit which you can then apply the available credits to your Credit Memos/Refunds.
To apply the credits to your refund, here's how:
- Go to the Customers menu and select Create Credit Memos/Refunds.
- Select the customer for whom you want to apply for the credits.
- Select the Use Credit to apply to invoice option under the Use Credit to give refund menu.
- Review it and then select Save and Close.
For future reference, you can check this article to learn more about receiving and processing customer payments for invoices: Take and process payments.
If you have further concerns about applying the credits, please tag me in the comment section, @T4KB. I'll assist you in any way possible.
