Checking subtotal, VAT and total: calculation errors on invoices

Why you recalculate subtotal, VAT and total on purchase invoices, which deviations occur and how AI checks every invoice automatically before booking.

Sebastian de Goeij 5 min read Updated

Short answer

A totals check verifies that lines add up to the subtotal, VAT matches the rate and subtotal plus VAT equals the total. Deviations point to a calculation error, misread amount, discount or rounding. Autoboeker runs this check on every invoice and sends deviations to review.

Key takeaways

  • Lines must add up to the subtotal.
  • VAT must match the rate per line.
  • Subtotal plus VAT equals total.
  • Small differences are often rounding.

How does Autoboeker check amounts?

Subtotal, VAT and total are recalculated per line and rate, with checks on missing or unusual VAT. If it does not add up, the invoice goes to review.
