For small businesses, bookkeepers and anyone who approves supplier invoices.
A supplier invoice check is the review a business runs on an incoming invoice before approving and paying it, to catch billing errors that quietly cost money. Done by hand it is slow and easy to skip, so overcharges, duplicate charges, wrong VAT and surprise fees slip through. This tool reads the invoice against your order or agreement and flags overcharges, duplicate charges, wrong VAT, unbacked fees, quantity mismatches and totals that do not add up, as a GREEN/YELLOW/RED status. The AI never approves or pays. You keep every decision.
By hand
a few minutes per invoice to check by hand, so most get paid unchecked
With Tedrix
seconds
Across a stack of supplier invoices a month that is real money caught, on the ones that would otherwise be paid on autopilot.
Estimated from a typical workflow — your numbers depend on volume.
What it does
Supplier invoices are easy to pay on autopilot, and that is exactly where money leaks. A unit price a little above what was agreed, a fee that was never in the order, VAT on the wrong base, or the same line billed twice. Each one is small, easy to miss, and adds up over a year of invoices.
This tool reads the invoice and, when you provide it, the order or agreement, and flags the discrepancies that cost money, with the amount where it can be worked out. It never approves or pays an invoice, and it never invents an agreed price it cannot see. When it cannot verify something it says so and puts it on a short list for you to check. You make every decision.
What goes in
A supplier invoice as a PDF or a photo, plus the order, agreement or quote if you have it. A short note describing what was agreed also works.
What you get back
A check: the invoice lines each marked matches, discrepancy or unclear, a discrepancies list with the money difference where known, a totals summary, a short list of what you still need to verify, and a GREEN/YELLOW/RED status.
What the output looks like
Example: a monthly cleaning invoice for a café in Gothenburg, checked against the agreement.

How it runs
Upload the invoice
Drop in the supplier invoice and, if you have it, the order or agreement. A PDF or a photo is fine.
It reads and cross-checks
One pass reads the invoice against what was agreed and lines up prices, quantities, VAT and fees.
It flags the discrepancies
Overcharges, duplicate charges, wrong VAT and unbacked fees are flagged, with the money difference where it can be worked out.
You decide
A GREEN/YELLOW/RED status and a short check-list tell you what to look at before you approve or pay.
Common questions
What does the invoice check actually catch?
Overcharges against your order or agreement, duplicate charges, wrong or inconsistent VAT, fees that were never agreed, quantity mismatches, and totals that do not add up. Where the difference can be worked out from the documents, it shows the amount.
Does it approve or pay invoices for me?
No, deliberately. It flags discrepancies for you to review. It never approves, accepts or pays an invoice. Every decision stays with you.
What if I do not have the order or agreement?
It still checks the invoice on its own for duplicate charges, VAT and math errors. For anything that depends on the agreed price it says it could not verify that and puts it on your check-list, instead of inventing an agreed figure.
