I have two questions but they are basically the same..... I think.
First one is- I have sent an invoice and delivered goods, the client was on payment terms which I have agreed to extend.
I'm on monthly invoicing VAT terms so when do I declare the sales? The date of invoice, or date of payment (new payment date).
Second is basically the reverse, if I have received an invoice and goods, but agreed a later repayment date than stated on the invoice, when do I report for VAT purposes? The date of delivery, or the later payment date?
Thanks in advance
