Every transaction checked for the right VAT treatment, not just the right format.

The GraphBit case review screen running a validation: a file is uploaded, each check runs in turn, and the case comes back validated, marked correct or sent for review.
A manual review reaching two of six transaction rows; the other four are not reviewed.

Problem Statement

Manual VAT review only reaches a sample, typically 1 to 5 percent of transactions. The rest is not wrong until an authority looks, and from 2028 the next audit reads every invoice by machine. A sample will no longer be enough.

VAT validation reaching all six transaction rows, each checked.

The Solution

Every transaction gets the same substantive check, not a sample, so nothing sits undiscovered until an authority finds it.

How GraphBit VAT Validation solves it

Substantive, not formal

A valid e-invoice can still be wrong on the tax. A format check confirms fields and arithmetic, not whether the exemption applied or the right rate was used. GraphBit checks that for every transaction.

Every transaction, not a sample

The same check runs on 100 percent of transactions, not the 1 to 5 percent a manual review reaches.

Reasoning attached, no guesswork

Every verdict comes with its reasoning attached. Where a case needs a human decision, the system says so and routes it to your expert before it is included in the filing. No guesswork.

Grounded in the law as it stood, on the supply date

Every verdict cites the provision, the guidance and the effective date that applied, so a check made today can be replayed exactly, years later, in front of an auditor.

Your VAT position, at a glance

Every transaction rolled up into a single view, so you always know how much VAT is at risk, and every flagged case goes to a human, never an automated guess

A verdict card for 28 grocery items at two VAT rates with the delivery fee split, marked correct: €5.49 of VAT reported and €5.49 expected.

Correct

The treatment holds. Documented with the derivation, which is evidence that it was reviewed.

A verdict card for the Warsaw case, marked incorrect: €0.00 of VAT reported against €19,000.00 expected, because the Polish VAT ID was not valid on the delivery date.

Incorrect

A specific finding with the provision and the reasoning, correctable before the invoice goes out rather than in the audit.

A regulatory update waiting for approval: a letter from the Federal Ministry of Finance, valid from 1 March 2026, with the date it applies from and the VAT rates it affects.

The law changes. The graph changes with it, after an expert has signed it off.

Official sources are monitored continuously. Every new ruling, decree or amendment reaches the system as a draft update, linked to the provisions it affects. A tax expert approves it before it goes live. Transactions from before the change are still checked against the law in force on their date.

FAQ

Questions we get asked before rollout.

Correct means the treatment holds, documented with the derivation, which is evidence that it was reviewed. Incorrect means the treatment needs review on the specific findings with the provision and the reasoning, correctable before the invoice goes out rather than in the audit.
