Customer questions invoice later, already paid previous quarter

Dear Marc,

For the benefit of other Community visitors, I am sharing the answer our Support team provided you with:

It is certainly not permitted to create an invoice without entering it in the accounts. However, there is another way to resolve this issue. I assume that you first entered the income as daily receipts and that your customer now wishes to receive an invoice. Because the quarter in which the payment was made has already been closed, you can no longer remove this from your daily receipts without having to submit a corrected vAT declaration. This is a lot of work and hassle, so we are going to offer an easier way. You can create a credit note under Income & Expenses > Manual input. You write this out to a private person, but do not send it to the customer under any circumstances. This is an internal credit note to do your accounts in order. Afterwards, you create an invoice for the customer for the full amount. In the comment, you write to your customer (€X already paid, €Y still to be paid). Only in this way have you completely neutralised the previous day's receipt and do you have the full, correct amounts to enter in your own accounts and those of your customer.

Kind regards,
