When you’re processing purchases whatever VAT was calculated by the supplier should always take precedence over anything calculated by QuickFile. The invoice says you were charged VAT of £11.84, so that’s the amount you are entitled to reclaim.
You could simply add an extra line to the purchase invoice for -30.13 at 0% VAT, which would show in your books as printer ink at £29.08 and VAT of £11.84.
Alternatively, and perhaps more accurately, you could split it into two:
- Create a new nominal code from your chart of accounts in the “sales” range for suppliers goodwill payments and tick the option to also allow this code to be used on purchases.
- Create an (unpaid) purchase for the full £59.21 + VAT £11.84 tagged to stationery (or wherever you normally put printer ink).
- More options → credit note, and make the credit note be -£30.13 @ 0% VAT, assigned to the new suppliers goodwill code
This will leave an outstanding balance on the purchase of £40.92, for which you can record payment in the usual way. Your books will show £59.21 expense for the printer ink and £30.13 income for the goodwill payment. And the VAT return will include a total (for the purchase minus credit) of £29 in box 7 and £11.84 in box 4.
