What the Leak Check finds

Six leaks we check on every invoice.

For each one we calculate what it costs you, per supplier. Click for the rule and the calculation.

IN-01

Price up

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.

Last priceSame itemEffect per yearEmail ready

IN-02

Silent indexation

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.

Price vs last yearPattern per supplier

IN-11

Booked twice

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.

IN-12

Above the agreement

More than agreed

The agreement sits in an email from last year. The invoice ignores it.

We recalculateInvoice price against the price agreement.

VR-01

Freight and surcharges

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.

IN-03

Never compared

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.

Made-up company and amounts. This is what your list will look like.

Why nobody catches it

It is nobody’s job. So nobody does it.

Everyone sees a piece of the invoice. Nobody puts it next to last year’s.

Accounts payable

Does

Books what comes in and checks that it adds up.

Misses

Not whether the price still matches last year.

Purchasing

Does

Negotiates when a contract ends, if there is time.

Misses

Not the hundreds of lines that come in afterwards.

Management

Does

Approves the total and steers on margin.

Misses

Only sees the leak when the annual figures disappoint.

Large companies have a purchasing department for this. We do it in software, for a fixed fee.

1

Code does the maths

Prices and differences are right to the cent. AI only reads the PDF.

2

A person approves

Nothing goes to a supplier until someone on your team has seen it.

3

A public rulebook

Every check is in it, with the calculation. Written with a former operations director of a large food producer.

How the Leak Check works

You send invoices. We send amounts back.

Free, with no integration or IT project. An export and the PDFs from your largest suppliers are enough.

  1. 1

    Send 12 months of invoices

    An export from your accounting, and the PDFs from the suppliers that make up about 80% of your purchasing.

  2. 2

    We put everything side by side

    Every line against the last price, the agreement and other suppliers. A person reviews every finding.

  3. 3

    You get the amounts

    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.

  4. 4

    You decide

    You choose what to claim back or renegotiate. Your suppliers talk to you, not to us.

FAQ

Frequently asked questions

About the Leak Check, your invoices, your ERP and what it costs.

What does Agentfabriek do?

We check your supplier invoices and get back what you overpay. Every line goes next to the last price, the price agreement and other suppliers. Every leak is shown in euros per year, with the invoice line, the calculation and the email to the supplier ready. First over the last 24 months, then every month before you pay.

How do I start?

With the free Leak Check. You send an export of 12 months of supplier invoices and the PDFs from your largest suppliers. You get, per type of leak, what it costs you a year in euros, on two pages. No obligation.

What does it cost after that?

Margin Back costs €7,950 for the first year, or 12 × €695: a Leak Report over 24 months with every finding on an invoice line and the email to the supplier, then your new invoices checked every month for a year, and one hour with management every quarter. After that €650 per month, cancellable monthly. Just the Leak Report over 12 months is also possible, for €1,950.

How does the guarantee work?

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.

We already check our invoices. What would you still find?

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.

How is this different from a no cure no pay recovery firm?

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.

Which companies is it for?

Factories, wholesalers and other companies that buy and ship goods, with €3 million or more in annual purchasing: food, building materials, metal, plastics, packaging and distribution. If you buy from a handful of suppliers on fixed contracts, it is probably not worth it. We will tell you so.

Do we need to connect anything to our ERP?

No. An export from your accounting and the PDFs from your largest suppliers are enough, from Exact Online, AFAS, Business Central, Twinfield, SnelStart, SAP or any other package. After that you send your new invoices every month, or create an API key yourself.

Is this AI? Who decides?

AI only reads the PDF invoices. Any invoice whose lines do not add up to the total is set aside and checked by hand. Plain code does the comparing and the maths, following our public rulebook. A person reviews every finding, and nothing goes to a supplier without your approval.

What happens to our data?

Your files are stored on a server in the EU and only we can see them. We read PDFs 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.

More questions?

Call or email. You get an answer from the people who build the checks, not from a sales team.

How much did you overpay last year?

The Leak Check goes through 12 months of supplier invoices and shows, per type of leak, what it costs you a year. Free.
