How it works

Three steps. Zero manual work.

Step 1

Connect your email

Link your Gmail or Outlook in one click. ininvoice automatically detects invoices, purchase orders and delivery notes arriving in your inbox — without you lifting a finger.

Step 2

Our engine analyzes every invoice

It automatically identifies the right PO (even when the data has OCR errors), matches every item line by line, scores the invoice risk and generates an explanation of what it found.

Step 3

You only see what fails

You get a clear report. What checks out, in green. What has a problem, in red with the exact variance amount. Ready to act.


What exactly do we do?

When a supplier invoice lands in your inbox, you need to check that the amount billed matches what you ordered and what you received. Three documents that must line up — a documentation requirement most tax authorities expect for VAT deduction. We compare them for you automatically.

The invoice

What the supplier charges you. It says: "I'm billing you X units of product Y at Z each."

The purchase order

What you ordered. The document that says: "I want X units of product Y at Z each."

The delivery note

What actually arrived at your warehouse. It confirms which items and quantities were received.

Real example: You ordered 100 boxes of screws at €5 each. The supplier ships 95 boxes but bills you for 100 at €5.20. If you only check the total, you might miss it. But we look item by item: we catch the €0.20/unit price increase and the 5 missing boxes. Two errors you would have paid for without automatic checking.


Under the hood

Here's what happens every time an invoice arrives

From the moment a supplier emails you an invoice until you know exactly whether it's correct, how much you're being overcharged and what to do next. All automatic.

Classification

It knows what every document is. Even if the scan is rough.

The AI identifies whether it's an invoice, a PO or a delivery note. It extracts the supplier, the tax ID, every product line and the amounts. If the scan dropped a digit or the name has a typo, it fixes it before moving on.

Matching

If a single cent is off, you'll know.

We match every invoice line against your PO and your delivery note. Price, quantity, supplier: it all squares up or we flag it. Line by line, not headers that hide errors.
