Invoices hand-matched to POs already in the ERP

The question this file answersDo we really need a person to retype an invoice whose purchase order is already sitting in the ERP?

Fits: finance teams handling 500–5,000+ supplier invoices a month by email, post and portal, with the purchase orders and goods receipts already in the ERP

Not for: firms already on mandated e-invoicing with PO flip, or with only a few hundred invoices a month — the checking step is not where the cost is

Typical day

What the desk looks like today

Typical, from the finance playbook. A mid-size firm handles 500–5,000 supplier invoices a month, by email, post and supplier portal. The AP clerk keys the header and lines, looks up the purchase order, finds the goods receipt, compares the three, posts what agrees into the ERP, chases approval, files the PDF and answers the supplier's “when will we be paid?”. IOFM (2023) puts the manual cost at €12–15 an invoice. The pain peaks at month-end close, when the clerk is asked for accruals on invoices nobody has matched yet.

What changes

What Monday looks like after

Month-end, the week AP dreads. Instead of a mailbox of PDFs, the clerk has a list of invoices that failed a check — a unit price above the PO, a quantity with no goods receipt, a supplier the master does not know. Clean invoices from regular suppliers are already posted as drafts, waiting for the usual approver, and the accruals question has an answer. The clerk is still there for the supplier calls and the disputes; the keying is not. You can see, per supplier, how many invoices went through untouched. IOFM (2023) puts a manual invoice at €12–15 and an automated one at €3–5 — their survey, not our measurement.

Typical, not a measured client result. Every figure here comes from the playbook source named below.

~50–70%

less manual invoice handling — Ardent Partners (2023); 80%+ touchless is a best-performer claim, not a promise

Before: a clerk extracts, matches and retypes every invoice into the ERP. After: AP studies put 50–70% of that handling within reach — payment still waits on a person when the documents disagree.

Where this number comes from

Ardent Partners “AP Automation” (2023) puts best-in-class AP at 80%+ touchless invoice processing; IOFM (2023) puts the cost per invoice at EUR 12–15 manual against EUR 3–5 automated. Playbook range 50–70%. Industry benchmarks, not our measurement.

What we install

What we put in front of the systems you already run

Your ERP stays where it is — SAP, Oracle, Dynamics or whatever runs AP today; we add a checking step in front of posting:

invoices are read from the shared mailbox and the supplier portal — PDF, scan or e-invoice
header and lines are extracted
each line is matched to the purchase order and the goods receipt already in the ERP
lines inside your tolerance are posted as a draft for the usual approval
anything that does not match lands in a review list with the three documents side by side and the reason — price, quantity, missing receipt.

Every match and exception is logged with its reasoning, for your auditors. The suppliers whose layouts we see most often come first.

What stays human — and what this will not do

Vendor disputes. New vendor set-up. Policy changes. Anything outside the tolerance.

What can go wrong — and what we do about it

Invoices without a purchase order cannot be three-way matched; those go to a coding rule, and the pilot is scoped to the rest. Goods receipts posted late produce “missing receipt” exceptions that are really timing — expect a noisy review list until receiving catches up. Where the ERP will not accept a draft posting through an API, entries go via import files, with IT time. The Ardent Partners 80%+ touchless is best-in-class; the playbook's working range is 50–70% of handling, and disputes, new vendor set-up and policy changes sit outside it.

How long it takes, and what we need from you

Audit, about two weeks (€1.5–3K): we sit with AP, count a month of invoices by supplier and channel, check how many have a PO and a receipt, and see whether the ERP takes a draft posting through its API. Pilot, 3–5 weeks (€10–20K) — the finance playbook rates AP medium complexity: the suppliers with the most invoices, every exception reviewed, every posting a draft. Production: the remaining suppliers, then non-PO invoices. From you: mailbox and portal access, a month of posted invoices, your tolerance rules in writing.

The path: free 60-second estimate → free 20-minute review → paid audit of this one process (€1.5–3K, typically two weeks) → pilot with your people in the loop (€10–20K, weeks, not quarters). No transformation programme. Prices are public, on the services page →

This is about you if…

Do supplier invoices still arrive as PDFs and get keyed into the ERP by a person?
Is there a purchase order and a goods receipt in the ERP for most of them?
Is it 500 invoices a month or more?

What does this mean in euros?

That depends on your volumes and wage costs — this page will not invent the number. The free 60-second estimate runs that calculation from your answers, with every multiplier sourced.
