Not a valid tax invoice
Missing words, a missing or malformed TRN, no AED tax amount, no exchange rate on a foreign-currency invoice. The failing field is named with its article.
Hysaab Finance · Invoice checks
Every supplier invoice, tested before you claim the VAT.
Every field read, every sum redone, every rule tested. A person decides what gets claimed.
One invoice, start to finish
Follow INV-2107 from the inbox to a claim you can defend.
Illustrative invoice. Al Madar forgot its TRN and billed a client dinner on the same page. Both get caught, for different reasons.

Each client gets its own intake address. Forward it, or ask suppliers to send invoices straight there. A folder upload and a history import run the same pipeline.
What it catches
Nine ways a VAT claim fails an audit.
Each one tested.
Every finding carries a severity and a legal reference, so the audit trail explains itself. Hold means the VAT waits for a fix. Review puts it in front of a person. Flag records the risk without stopping the claim.
Reconciliation · Hold
Numbers that do not add up
Lines, VAT at the stated rate and the total are recomputed in code. A wrong rate or a total that is off by more than your tolerance is caught on the line it happens.
Register · Hold
Duplicates and re-issues
Every invoice is keyed by supplier and number, with a fingerprint of its amounts and date. An exact re-send is blocked; a corrected re-issue supersedes the old copy.
UAE Art. 53 · KSA Art. 50 · Flag
Blocked input tax
Entertainment, hospitality, personal-use vehicles and employee benefits are flagged as potentially blocked, even on a perfect invoice. A flag, never a silent block.
Reverse charge · Review
Imports categorised, not failed
A foreign supplier or a reverse-charge statement moves the invoice to RCM. The findings are kept, but it leaves the chase queue instead of looking like a failure.
Claim window · Flag
Late claims
In the UAE, input VAT is claimed in the invoice's period or the next. Older invoices are flagged so the receipt-date evidence is kept. In KSA age is shown for information.
Recipient · Review
Not addressed to your entity
The recipient is matched to your group by TRN, then by name and aliases. An invoice addressed to someone else is stopped, and its own compliance is still graded.
Supplier memory · Review
A TRN that changed
Each supplier's established TRN is learned from past invoices. A new invoice showing a different one is put in front of a person, because that is usually a misread.
Cabinet Decision 149 · Flag
The October 2026 recovery rules
Cash-settled supplies above the Ministerial threshold, employee accommodation without a MoHRE mandate, and separately priced bundles are being added as checks ahead of 1 October 2026.
Configuration
Set a materiality threshold and immaterial VAT drops out of the queue. Whitelist trusted suppliers. Choose monthly or quarterly periods with FTA-staggered quarters, per entity. Import old trackers and they are rechecked on day one.
The register and the report
The file your auditor asks for, and the page your client reads.
Every invoice, verdict and claim sits in one register by filing period. The monthly report is built from the same numbers, so the two never disagree.

The register exports to Excel in four sheets with low-confidence cells highlighted. The client compliance report is built from the same numbers.
Where the people stay
The AI reads.
Your team decides.
Disagreements go to a person
When two models read a field differently, both values are shown and a reviewer chooses. Every correction is journaled with who made it and why.
A questioned finding keeps its band
The verifier agent can confirm or question a finding, but it cannot delete one. Its note goes to the reviewer with the evidence.
Suppliers are chased when you say so
Correction requests are drafted with the exact defects and articles, editable, and sent only when someone presses send.
Client email has two gates
A reviewer agent inspects every prepared client email first, then a two-step human sign-off releases it.
Why we built it
We built it for our own tax team first.
A Gulf tax practice runs on supplier invoices: hundreds a month, each one a small bet that the paper holds up. Checking them properly meant late nights with a calculator. Not checking them meant carrying the risk quietly into the next audit.
So we built the checker our own team runs every day. It reads every invoice, redoes every sum, tests every rule the law enforces and puts its working on the table, so the judgement and the client relationship stay with the people.
Our promise
We will never call a claim safe that the paper cannot defend, and we will always tell you why.
