Matching
N-way matching: purchase order, goods receipt, invoice, contract
N-way matching compares the invoice with the purchase order and the goods receipt (three ways) and adds the contract in four ways. The Matching agent does it line by line, applying your tolerances by supplier, by purchasing category and by amount. You decide: Zylio commits to nothing without your approval.

Matching
“Three-way matching does not get stuck on clean invoices. It gets stuck on everything else.”
You are not controlling 5% of your procurement out of negligence. You control 5% because nobody has the time to do the remaining 95%.
Book a demoTwo, three or four ways: what each level adds
The N in N-way is the number of documents compared. The higher it goes, the more the invoice is judged on facts rather than on amounts that happen to agree.
2 ways
Purchase order and invoice
The most common match: what was ordered against what is invoiced. It says nothing about what was actually delivered.
3 ways
Purchase order, goods receipt and invoice
The goods receipt enters the comparison. Invoicing before actual receipt, a partial or split delivery becomes visible.
4 ways
Purchase order, goods receipt, invoice and contract
The contract price joins the quantity. The line is judged both on what was delivered and on the agreed rate.

Matching
Your tolerances, not ours
Compliant cases go through on their own. The others arrive qualified, with the discrepancy already costed.
- A long-standing partner and a one-off supplier do not call for the same level of scrutiny.
- A tonne of raw material and a day of services are not tolerated in the same way.
- A negligible discrepancy on one line, repeated, stops being negligible. The threshold is yours.
Matching, situation by situation
Each situation has its page: what is read, what it is compared with, what is escalated.
The other situations handled by the Matching agent
- Invoice reconciliationThe invoice matched to the order and the receipt, line by line, with your tolerances and the gap already quantified.
- Accounting reconciliationInvoices, credit notes and payments tied to supplier ledger entries, clearing proposed, open items qualified: a close without an inventory.

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 N-way matching mean?
It is the matching of an invoice with the documents that justify it. Two ways: purchase order and invoice. Three ways: the goods receipt is added. Four ways: the contract is added, to check the price at the same time as the quantity. The N is the number of documents compared.
Why does three-way matching block in my ERP?
Because your ERP, the integrated management software that carries your purchase orders and your invoices, expects an exact match. It does not get stuck on clean invoices, it gets stuck on everything else: diverging descriptions, units to convert, grouped goods receipts, charges absent from the purchase order.
How are services with no physical goods receipt handled?
They are matched on the elements that stand in for it: purchase order, milestone, period, approved quantity. No discrepancy is dismissed in silence; anything that matches no rule is escalated, with its reason.
Does Zylio replace my ERP?
No. Your ERP runs the process and remains the source of truth. Zylio handles the exception, on top of it, and feeds the results back. No additional development inside your system.
How do I check a Zylio conclusion?
Every discrepancy opens onto its evidence: the contract clause and the invoice line, highlighted side by side, with the calculation shown.
How long before a first result?
The diagnostic produces a figure in three weeks, on your real data and a framed scope.
Measurable impact in every environment

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.
