If you are VAT reg and they are not too old I would enter them with a date in the current Vat Quarter.
Thats what I was told by an accountant when I have year end stuff to post and we had duplicate invoices on there and had to do credits to get rid of them. (It was an error from the original bookkeeper).
Others may give a different answer so wait and see if anyone else will come along.

Hi, how were the payments entered in the first place if there were no invoices to enter them against? Were they just entered with the Write cheques function?
