Purchasing management
Purchasing management: turn every euro of supplier spend into a profitability lever, with the evidence
Purchasing management becomes a profitability lever when supplier spend is controlled after the negotiation, not only before it. Zylio reads contracts, orders, receipts and invoices, checks every paid line against what was negotiated and shows each discrepancy with its proof. Management decides; nothing is committed without validation.
The situation
Where purchasing management loses margin after the signature
A procurement team negotiates well. It secures a framework contract, a rate card, volume discounts, a reasonable indexation clause. Then the life of the contract begins: hundreds of invoices a month, several entities, sometimes several ERPs. Nobody has time to reread every line. Control is done by sampling, and the gap between what was negotiated and what is paid settles in quietly.
This is not a matter of skill but of volume. A framework contract can carry thousands of price lines; a services invoice sometimes runs to more than a hundred. The ERP’s matching compares totals and lets unit price discrepancies through. Margin is not lost in one go: it leaks, a few cents per line, across thousands of lines.
For a chief executive or a finance director, the question is therefore not “did we negotiate well” but “is what we negotiated being applied”. That is where purchasing management becomes a profitability lever again: in controlling execution, line by line, with evidence you can put in front of the supplier.
The discrepancies
Six discrepancies that classic purchasing management does not see
They come back in every industry, on every ERP. Each one is small; it is their repetition that costs.
Invoiced price above the negotiated price
The item is in the contract, but the line is invoiced at list price. The gap is a few cents and repeats on every order.
Revision outside its due date
The annual increase is applied three months early, or calculated on an index that is not the one in the contract.
Volume discount forgotten
The volume tier has been crossed, but the supplier keeps invoicing at the previous tier’s rate.
Off-contract purchase
An entity orders from a supplier who is not referenced, or a service outside the agreed scope, at full price.
Quantity discrepancy
Ten invoiced, eight received. The partial delivery was not matched before payment.
Credit note never applied
The supplier promised a credit note after a claim. It was never deducted from an invoice.
The mechanism
What Zylio reads, and what it checks it against
Zylio is a platform of AI agents for procurement spend control. It sits alongside your tools and reads the documents you already have: framework contracts, rate cards, supplier price lists, amendments, purchase orders, delivery notes, invoices and credit notes. Nothing to re-key, nothing to change in the ERP: exports or the API are enough.
Each agent has a bounded role. Capture reads and extracts line by line. Compliance checks every invoiced line against what was negotiated. Matching reconciles order, receipt and invoice. Exception takes on the cases that fit no standard flow. Two intelligence layers complete the agents: Graph, the knowledge graph layer, links every price to its contract and its proof; Insight, the procurement intelligence layer, answers management questions, every figure verifiable.
- 01
Read
Every format: native PDF, scan, spreadsheet, structured feed. Each extracted value stays linked to the page and line it came from.
- 02
Check
The contract clause and the invoice line, side by side. Price, discount, index, quantity, payment term.
- 03
Build the case
Every discrepancy comes up with its reason, its amount and its documentary proof. You decide whether to claim, accept or renegotiate.
For management
What management gets: one figure per discrepancy, one proof behind each figure
The first change is scope. Where control used to cover a sample, it now covers from 5% to 100% of your spend, depending on what you choose to hand to the agents. On the scope analysed, recovered margin sits between 1% and 7%: documented overpayments that you choose to claim back or to bring to the next negotiation.
The second change is time. Procurement and accounts payable teams no longer reread compliant invoices: they handle discrepancies that are already qualified. From 15% to 45% of time given back to teams, per FTE, depending on scope and data maturity. That time goes back to negotiation and steering, not to data entry.
The third change is the conversation with the supplier. A claim backed by the clause and the invoiced line, highlighted side by side, is no longer a hunch: it is an enforceable reason. And a renegotiation starts from the real history of what was invoiced, not from the theoretical rate.
Zylio does not promise “automatic” margin. It shows what has already been paid in error and provides the evidence to decide how to act.
Your tools
Without changing ERP or process
Zylio replaces neither your ERP nor your ordering tool. It reads their exports or their API (SAP, Sage, Oracle, Microsoft Dynamics 365, NetSuite, Cegid, Workday) and writes nothing back. Your approval flows remain yours; the agents bring them investigated discrepancies, never decisions taken on your behalf.
Three limits always hold. We do not touch the ERP. We commit nothing without your validation. We contact no supplier. Your data is hosted in France, is never used to train a model and is never shared between customers.
What we read and what we never modify, for each ERP.
Getting started
Where to start: a three-week diagnostic, on your data
The shortest way to measure what your purchasing management lets through is a three-week diagnostic on your own contracts and invoices. You choose a scope: a spend category, a major supplier, an entity. We read the documents, check every line against what was negotiated and hand back the discrepancies, quantified and sourced.
You leave with a list of enforceable discrepancies and a measure of what systematic control would change on that scope. The diagnostic is billed on success, on the discrepancies recovered. If there is nothing to recover, we say so.
Scope, data requested, deliverable, success-based billing.
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
What does purchasing management mean, as Zylio understands it?
It is the whole cycle, from the expression of need to payment, but Zylio works on its least controlled part: execution. Once the contract is signed, is every order, receipt and invoice consistent with what was negotiated? That is where profitability is decided, line by line.
Does Zylio replace a purchasing management tool?
No. Zylio does not handle purchase requests, orders or approvals: those flows stay in your ERP or your procure-to-pay tool. Zylio reads what they produce and checks that what is paid matches what was negotiated.
Which documents do you need?
Framework contracts, rate cards and amendments, then the orders, receipts and invoices for the period, in whatever form they exist: PDFs, scans, ERP exports. Zylio reads every format. No preparation or re-keying is asked of your teams.
How is profitability measured?
Discrepancy by discrepancy. Each overpayment is quantified, linked to the clause and the invoiced line, and classified by supplier and by reason. The total on the scope analysed is the figure you can bring to the board, with the evidence. Nothing is estimated without a document.
