I submitted an invoice to a client (Inv. #2948 in my account), and my client pointed out that the VAT on VAT on £12,598.38 is showing as £2,499.93 but should be £2,519.68.
To track the error, I copied the invoice (Inv #2956 in my account), and discovered that Quickfile has made an error in the VAT calculation. I have saved this invoice so that tech support can examine it.
On further inspection, I suspect that this is a PICNIC error (problem in chair not in computer), because 0.25 is also the quantity, so it seems that I might have overwritten the VAT amount.
Slightly concerning that Quickfile allows this without any kind of warning or error message. I’ve discovered that you can put any amount into the VAT column and Quickfile will happily accept the error, misrepresenting the VAT calculation with no problem at all.
If the amount entered is different from the amount calculated, shouldn’t Quickfile flag this up?
… but it might be worth considering a subtle warning of some sort if the entered value is significantly out from the calculated one - not refusing the entry but maybe putting a yellow background or icon or similar in the VAT amount box on the editing form.
