What if a Hirer Pays some Money in Advance or has Paid more than the Invoices we have Raised?
The procedure to follow is exactly as What happens when I save a receipt? except that any payment which cannot be allocated to an outstanding item is shown as a single value next to unallocated.
When you click on Save you will be asked to confirm that you want to save the unallocated amount as a payment on account.
When you receive another payment from the Hirer you will be able to allocate the new payment, along with the payment on account, to the outstanding items.
Alternatively when you raise an invoice which corresponds to the amount they paid on account you can record a receipt of a zero amount and allocate the payment on account to the invoice you have raised
