In the capture it is handy to have the validate total line amount to check if the lines + VAT add up to the total amount in capture, but there are some improvements.
1. Make the warning bigger when there is a difference
2. Can the total value of lines + VAT be displayed? With invoices with many lines there might be a 1 cent rounding difference but we would not know how big of the error currently is.
3. Can there be a pop-up warning to confirm the posting if there is an imbalance? I could still send the invoice to the Document Import step despite a difference in lines + VAT and total.
