VAT Invoice Check
Methodology

How VAT Invoice Check builds its result

VAT Invoice Check is a rule-based public explainer, not an official validation service. It compares the scenario you select with a checklist of the invoice elements and special references that are commonly expected in EU VAT invoicing guidance.

What the checker looks for

  • supplier identity details
  • customer identity details where the scenario usually needs them
  • invoice date and unique number
  • goods or services description
  • net or taxable amount
  • VAT rate and VAT amount where VAT is charged normally
  • total amount
  • VAT identification numbers where the treatment usually depends on them
  • special wording or references for reverse charge, exemption, self-billing, cash accounting, and corrective documents

Scenario-based logic

The tool does not apply one universal checklist to every invoice. It adjusts expected items depending on whether you are checking a domestic taxable invoice, an intra-EU B2B supply, a reverse-charge case, an exempt treatment, or a credit note.

How wording prompts work

When a scenario depends on a specific treatment reference, the tool surfaces a conservative wording reminder. These prompts are practical guidance only, not official statutory text and not a substitute for local advice.

What the checker does not decide

  • It does not determine whether the VAT treatment is legally correct.
  • It does not interpret the commercial substance behind the transaction.
  • It does not cover every member-state exception, sector rule, or regime variation.
  • It does not validate OSS/IOSS, margin schemes, customs-linked import VAT, or other special frameworks in depth.

Recommended use

Use VAT Invoice Check as a fast first-pass validation layer before issuing or accepting an invoice. If the transaction is unusual, high value, cross-border, or audit-sensitive, confirm the treatment and wording with a qualified adviser.

Primary source base

  • EU VAT invoicing page: core invoice elements and extra references often required in special cases.
  • VAT for businesses in the EU: the common EU-wide invoicing framework and the reminder that local rules can still apply.
