The basics

What is an AI invoice VAT check agent?

It tests whether the supplier VAT number is present and well formed, and whether the invoice shows required items such as date, description and the buyer's details.

Read the full explanation

It flags invoices where the rate looks unusual for the item, where VAT is missing, or where reverse-charge wording is present, and sends them to a person.

Where it breaks

Why this step is hard by hand

A VAT claim depends on the invoice being correct, and gaps are usually found after the invoice is booked, when fixing them is harder.

A single wrong digit invalidates a VAT ID.

One invoice can hold standard, reduced and zero-rated lines.

A missing field can weaken a claim.

The invoice shows no VAT but the buyer must account for it.

VAT must reverse with the original.

The path

How the agent does it

  1. 01Extract VAT data

    Reads net amounts, VAT rates, VAT amounts and VAT numbers, line by line.

  2. 02Recalculate

    Checks that each VAT amount equals net times rate, and that line VAT sums to the invoice VAT.

  3. 03Test the VAT numbers

    Checks the format of supplier and buyer VAT numbers and compares with vendor records.

  4. 04Check required details

    Looks for the items your rules require on a valid VAT invoice.

  5. 05Flag for review

    Sends mismatches, missing numbers and reverse-charge cases to the tax or AP reviewer.

Questions

Frequently asked questions

Quick answers to what people ask most about invoice VAT check.

Book a demo
What is an invoice VAT check?

It is a check that VAT on a supplier invoice is correctly shown: the VAT number, the rate, the VAT amount and any mandatory details needed to support a claim.

What does the agent look at?

It checks that VAT equals net times rate, that VAT numbers are present and well formed, and that required details appear on the invoice.

Can it confirm a VAT number is genuine?

It checks format and compares it with your vendor record. Confirming it against an official register is a step a person does or approves.

What about reverse charge invoices?

The agent flags the wording and the absence of VAT, and passes the invoice to a person who decides on the treatment.
