Amending purchase invoices after VAT return filed - flat rate VAT

Hi! I’m trying to amend purchase invoices (mainly invoice dates as they are currently showing payment dates rather than invoice dates, but also a couple of them I want to delete and mark as cashback for petty cash) but as I’ve already filed the VAT return the invoices are locked. We are registered for flat rate VAT so don’t claim on outgoings anyway. Is there any way I can amend these invoices?
Many thanks,
Sarah

Hi @SarahJH, you’d have to roll back VAT Return to make necessary amendments and then submit again.

Hi PeterK. Thanks for your quick reply. Okay - I’ll go and do that now. Thanks v much.

No worries @SarahJH!
