How can I edit an invoice that displays “This transaction has been locked as it relates to a previously submitted VAT return. You can continue to log payments against this invoice but you cannot change the amount or the items.”? We need to remove a line item off this invoice as it has been added onto another invoice in the same quarter. The values are the same so the VAT return will be balanced.
I have tried moving the start VAT return date backwards but I get an error of “Vat start date must be after the last period filed.”
I’m afraid only rolling back the VAT return will allow you to edit a locked transaction. I personally would avoid doing this unless you absolutely need to.
As @Glenn mentions, you would need to rollback the VAT return, which can be done under Reports > VAT Returns, select the return and click ‘Rollback VAT Return’.
If it’s not going to change the values in any of the VAT return boxes then you should be safe to disable online filing in your QuickFile settings, roll back the return, edit the two invoices, then re-create the return in QuickFile, checking that the numbers are all the same as before, and “submit” it (without sending it to HMRC, as you turned off online filing).
If the change you want to make will change the figures in the VAT return in any way then I would leave it alone and make the corrections with a credit note and an extra invoice instead. These could be back-dated to the appropriate point within the quarter you’ve already filed, and QuickFile will pull them into your next return automatically.
