Example · made-up supplier
For each one we calculate what it costs you, per supplier. Click for the rule and the calculation.
More expensive than last time
The same item, the same unit, a higher price. No letter, no approval. You will not notice it on one invoice. Over a year, you will.
We recalculateEvery line against the last price of the same item, calculated against your volume.
Everything a few percent more expensive
On 1 January all rates go up. The letter disappears into a folder, or never arrives. Nobody signs, everybody pays, and next year another increase lands on top.
We recalculateEvery line from one supplier up at once, from a single date, calculated against your volume.
The same invoice, twice
As a PDF and via the portal, or forwarded twice. Even when the number is written slightly differently.
We recalculateSame supplier, number and amount.
More than agreed
The agreement sits in an email from last year. The invoice ignores it.
We recalculateInvoice price against the price agreement.
Surcharges nobody agreed to
A toll surcharge as a percentage, a fuel surcharge that never comes down. On a long freight invoice it disappears into the total.
We recalculateToll and fuel surcharge per carrier, as an amount and as a percentage of the freight.
The same supplier for years
What was once a good price is never looked at again. We flag every supplier that has not been compared with another in a long time, and prepare a request for quotes from three.
We recalculateEvery supplier above €10,000 a year with no second quote in 12 months.
This is what the Leak Report looks like. Who, what, how much, with the invoice line, the calculation and the email to get it back. Click a line.
Made-up company and amounts. This is what your list will look like.

Large companies have a purchasing department for this. We do it in software, for a fixed fee.
Prices and differences are right to the cent. AI only reads the PDF.
Nothing goes to a supplier until someone on your team has seen it.
Every check is in it, with the calculation. Written with a former operations director of a large food producer.
Free, with no integration or IT project. An export and the PDFs from your largest suppliers are enough.
An export from your accounting, and the PDFs from the suppliers that make up about 80% of your purchasing.
Every line against the last price, the agreement and other suppliers. A person reviews every finding.
Per type of leak, what it costs you a year in euros. If you want every line and the emails, there is the Leak Report.
You choose what to claim back or renegotiate. Your suppliers talk to you, not to us.
After you submit, you get an email with a personal upload link and a tip for the export from your system.
The Leak Check is free and shows what is there. If it is enough, Margin Back gets it back and keeps the leak closed for a year.
For factories, wholesalers and other companies with €3 million or more in annual purchasing.
Step 1
We check 12 months of supplier invoices. You get, per type of leak, what it costs you a year in euros.
From €3 million in annual purchasing. At most six a month.
Step 2 · After your Leak Check
first year, excl. VAT
We get back what is leaking, and keep it closed for a year.
Every finding with the invoice line, the calculation and the email to the supplier, ready to send.
Your new supplier invoices, before the payment run. Whatever is wrong is on your desk before you pay.
With management: what we found, what came back, what is still open.
After that €650 per month, cancellable monthly. Or 12 × €695.
We only offer Margin Back if the Leak Check shows at least €20,000 a year. If we then do not find it on invoice lines, you get the full €7,950 back.
Found means what you demonstrably overpaid or started paying more without approval, annualised, with the invoice line and the calculation attached.
About the Leak Check, your invoices, your ERP and what it costs.
Nothing. You only pay if you then want the Leak Report (€1,950) or Margin Back (€7,950 for the first year). There is no obligation.
Below that there is usually too little to check to be worth it, for you and for us. If you are below it, the calculators in the rulebook let you check the biggest leak yourself.
Supplier invoices or the purchase journal for the last 12 months, in Excel or CSV: supplier, invoice number, invoice date and amounts. An export with invoice lines (item, quantity, price) is even better. After your request you get a tip for your system.
Only us. The files are stored on a server in the EU. We read PDF invoices with an AI model over a business connection; that provider does not train on what it reads. If you do not continue, we delete the files 60 days after the result.
No. AI reads the PDF invoices. Any invoice whose lines do not add up to the total is set aside and checked by hand. Code calculates every amount according to the public rulebook, and a person reviews every finding before it goes into the result.
The Leak Check shows how much leaks and in which type of leak. Exactly where, with the invoice line, the calculation and the email to the supplier, is in the Leak Report. If you start Margin Back within 30 days, we deduct the €1,950 in full.
We go through the result together. If the Leak Check shows at least €20,000 a year, we offer Margin Back: a Leak Report over 24 months and then your new invoices checked every month for a year, for €7,950. If we then do not find the amount on invoice lines, you get everything back. If the Leak Check shows less, we tell you that too.
Because we review every finding ourselves before it goes into the result. If the month is full, the form puts you on the list for next month.
We only offer Margin Back if the Leak Check shows at least €20,000 a year. If we then do not find it on invoice lines, you get the full €7,950 back. Found means what you demonstrably overpaid or started paying more without approval, annualised.
Usually an invoice is checked against the order, and to see that it adds up. What is left is invisible on a single invoice: a price that crept up, an indexation nobody approved, a surcharge charged as a percentage, a supplier nobody has compared in years. You only see that when you put months of invoices side by side.
A recovery firm takes a share of what it recovers, in the Netherlands up to 35 or 40%. It looks afterwards, mostly at duplicate payments. We check every line against the last price and the agreement, for a fixed price, and you keep everything that comes back. If it is only about a one-off amount of a few tens of thousands of euros, a tiered rate is cheaper, and we say so.
