on 13.6.25, I received some money and put it as unallocated to a customer account. Since then I have done a year end. I now want to allocate this amount to an invoice (same customer) and am struggling to do so. Any advice?
Hello @AP123
You should still be able to pay the invoice from existing credit by doing the below
- View the invoice (it have a message such as the one below)

- Clicking Log Payment
- Selecting Apply from Credit (note it will use the oldest credit first, you can not specify a specific payment)
- Save
