Audit
In three weeks, know how much you have paid in error
In three weeks, know how much you have paid in error, and on what. The Zylio diagnostic analyses 100% of the lines of the scope you frame: framework agreement coverage, price history and variability, supplier credit notes never applied. It is billed on success, on the discrepancies recovered.
What a diagnostic reveals
Five questions a diagnostic answers with a figure, on your documents and not on a market average. You choose the ones that matter to you.
Framework agreement coverage rate
How much of your spend actually runs under a negotiated contract?
Price history
How have your prices moved, line by line?
Price variability
Is the same reference paid at the same price everywhere?
Recovery of supplier credit notes
Which credit notes are owed to you, and have never been applied?
Tailored audit
One purchasing category, one supplier, one entity: the scope you choose.

The audit says what was lost; the agents stop it happening again.
The diagnostic is a dated statement of fact: it costs what has already been paid in error, with the evidence behind each line. It does not say what will happen the following month. That is the role of the agents, which take up the same material and check it continuously.
The documents gathered for the analysis do not go back into a folder: they become reusable reference data, on which the agents then work.
What takes over
An orchestration of five specialised AI agents, to activate together or one at a time depending on your priorities: data consolidation, offer comparison, invoice compliance, matching, exceptions. Two procurement intelligence layers complete them: Graph, the knowledge graph, and Insight, on-demand analysis. Without changing tool or process. They investigate, you decide.
Your ERP (enterprise resource planning system) remains the source of truth and is not modified. We fit around existing processes, we do not replace them. No development added inside the core of the ERP.

- 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
How long before a first result?
The diagnostic produces a figure in three weeks, on your real data and a framed scope.
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.
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.
Which documents does Zylio handle?
Invoices, contracts and amendments, price lists and rate schedules, quotes, purchase orders, goods receipts, credit notes, statements, as native PDF, scan, photo or structured format, in several languages and currencies.
