At paragraph 16.4, VAT Notice 726 instructs reporting for EC sale of goods as follows:
"I account for VAT using the cash accounting scheme how should I complete box 8 of the VAT Return?
The value you enter in box 8, should be the total of all intra-EC supplies of goods made in that reporting period (excluding VAT) and not the value of payments received in that period. The total value of entries on your ESL should agree with the value entered in box 8 of your VAT Return (see Notice 731 Cash Accounting)."
The client software (QBO) is set to cash based VAT reporting, the sale flagged as ECG and the customer's VAT number verified, but the software will not populate box 8 for unpaid invoices (don't know if it will populate at all in future, as none of client's new overseas sales have yet been paid.)
Any tips for this or other software to produce a correct VAT return?
