Paid in full: new invoice

When I create an invoice from scratch (ie not using billable time), it always displays a PAID IN FULL stamp and shows within the list of invoices as PAID IN FULL. Clearly it isn’t ‘paid in full’ until money is received and logged against the invoice.

Have I misunderstood something (I usually do!)

Thanks in advance.

Can you post an image of such an invoice. Never seen that happening unless the total amount is zero.
Are you using a custom made HTML template ?

Using standard template.

Thanks

Total amount is credited, thus appears Paid in Full stamp.
Did you receive an overpayment for this customer. If so, amount is automatically credited.
Have a look in Summary tab under Customer credits (amount on right is a link).

You’ve nailed it! It was the Cust Credit explanation.
Thanks
