Estimate the return on your data, not on an average

We do not publish a generic calculator: an average ratio says nothing about your scope. The return is measured on your real data, during a three-week diagnostic that analyses every line of the scope retained and costs what has already been paid in error, with the evidence to back it.

A calculator does not calculate, it assumes

The ROI, or return on investment, of a procurement control depends on three unknowns: the share of your spend actually placed under a negotiated contract, the volume of lines concerned, and the state of your reference data. These three assumptions decide the result far more than the formula that combines them.

No one can set them in your place. That is why we measure instead of estimating.

Zylio does not promise “automatic” margin. It shows what has already been paid in error and provides the evidence to decide how to act.

How the return is measured

In three weeks, know how much you have paid in error, and on what.

Step 1
Frame the scope
One purchasing category, one supplier, one entity, or one of the diagnostic analysis angles. It is this choice that determines what the result measures.
Step 2
Gather the documents
Invoices, contracts and amendments, rate schedules and price lists, purchase orders and goods receipts, credit notes. As they stand, with no prior formatting work.
Step 3
Analyse every line
Each invoiced line is compared with the negotiated terms and with the other documents in the file. Not a sample: the whole of the scope retained.
Step 4
Cost and source
The result is an amount, broken down by cause, where each discrepancy opens onto its evidence. It is that amount which gives the order of magnitude of the return, not an average assumption.

The orders of magnitude we observe

These ranges situate the stake; they do not replace your own figure. The diagnostic, for its part, produces an amount attached to your scope.

Between 1 and 7% of margin recovered
on the scope analysed
From 15 to 45% of time given back to teams, per FTE
depending on the scope and on data maturity
From 5% to 100% of your procurement controlled
A 3-week diagnostic, on your own data

FTE: full-time equivalent.

What the measurement costs

The diagnostic is billed on success, on the discrepancies recovered: you only pay a share of what is actually recovered. Self-serve extraction can be taken on its own, from €99 excl. VAT per month for 500 pages analysed. The agents connected to your information system (compliance checking, matching, exceptions) start at €290 excl. VAT per month.

Nothing is lost. Everything can be checked, everything can be proven.

The contract clause and the invoice line, highlighted side by side.
Every extracted value stays linked to the exact place in the document where it was read.
The same case produces the same decision, today as in six months: the rules are applied deterministically.
No discrepancy is set aside in silence. Anything that matches no rule is raised, with its reason.
The agent records what it did, in the order it did it: who, what, how much, when.

Frequently asked questions

Why do you not offer an online calculator?

Because the result of a calculator depends entirely on the assumptions it is given: share of spend under contract, volume of lines, quality of the reference data. We prefer to measure on your real data during the diagnostic, and to give you back an amount sourced line by line.

How much does it cost?

Three models, known before you start. The diagnostic is billed on success, on the discrepancies recovered: you pay only a share of what is actually recovered. Self-serve extraction can be taken on its own, at a price per page set out on the pricing page. The agents connected to your information system (compliance checking, matching, exceptions) start at €290 excl. VAT per month.

How long before a first result?

The diagnostic produces a figure in three weeks, on your real data and a framed scope.

Does the data need to be perfectly clean?

No. The Capture agent is designed for heterogeneous documents and incomplete reference data; structuring is part of the deliverable.

Zylio fits into your existing ecosystem.

The ERP runs the process. Zylio handles the exception and recovers the value that escapes it: invoices without a purchase order, line-by-line price discrepancies, duplicates and overbilling, off-contract spend.
