Ask a purchase ledger clerk what Monday looks like. A shared inbox full of PDFs, a pile of goods received notes, and a list of suppliers asking when they will be paid. Purchase invoice processing is still, in most finance teams, one person reading a screen and typing into another.

The typing is not where the time goes. It goes to finding the purchase order, working out why the quantity is different, and chasing the warehouse for a receipt nobody booked. A faster scanner does not touch any of that.

This article covers what the process involves, why it stays manual, and what changes it. If the term capture is new to you, start with what supplier invoice capture means.

What purchase invoice processing involves

Receiving the invoice

By email as a PDF, by post, sometimes as a photo. Each one has to reach the right person before anything else can happen.

Matching and coding

The clerk finds the purchase order, checks the goods received note, and compares lines, quantities and prices. Invoices with no order are coded by hand and sent for approval.

Approval

A manager confirms what the match could not. The invoice sits in a mailbox, a reminder goes out, and the supplier calls before the answer comes.

Posting to the purchase ledger

Only now is the invoice entered. If something was keyed wrong, the fix is a credit note, a correction and an awkward phone call.

Why it stays manual

Invoices arrive in every format

Every supplier designs their own invoice. Some put the order number in the header, some in the email, some nowhere at all.

The order number is missing or wrong

The clerk searches the ERP by supplier and amount. A few minutes per invoice, hundreds of invoices a month.

The goods received note is late

The goods are on the shelf, but the receipt was never booked. The invoice cannot be matched, so it waits, and so does the supplier.

Scanners stop at the fields

A scanner reads the total. It does not know the purchase order says something else, because it never looked at the purchase order. The check is still yours, which is the whole point of three-way matching.

What fixes it

The invoice is read from the inbox

No forwarding to a folder and no upload to a portal. The email arrives and the work starts. That alone is how teams stop keying supplier invoices that arrive by email.

The supplier is identified without a template

A new supplier works from the first invoice. Nobody maintains a format per supplier, and nobody asks suppliers to change.

Every line is checked before posting

The purchase order and the goods received note are found in the ERP. Lines, quantities, prices and totals are compared before anything reaches the ledger.

Exceptions stop with a reason

A price difference or a missing receipt stops with a plain explanation. The team handles those, not every invoice.

The data stays where it is

A direct connection to the ERP, with nothing in the middle. Finance gets its check, and IT keeps the data in its own environment.

How it works with DOConvert

DOConvert is the AI layer for the ERP. It connects to Priority through the DOConvert Priority connector, which is bi-directional, and directly to Oracle Fusion Cloud ERP and Infor M3, with no middleware. Here is one purchase invoice.

The invoice arrives by email

As a PDF or a scan. Nobody moves it or renames it.

DOConvert identifies the supplier

From the sender and the document itself, with no template.

The order and the receipt are read from the ERP

The open purchase order and the goods received note, with what was ordered and what actually arrived.

Every line is compared

Say an invoice has 20 lines. Nineteen agree. One bills 500 units where the receipt shows 300.

The exception stops with a reason

That invoice waits with a short note about the 200 units. The purchase ledger team sees it straight away, not at month end.

Everything that matches is entered

As a purchase invoice linked to its order and receipt. For Priority users the full flow is in how to automate supplier invoices into Priority ERP.

For UK implementations DOConvert works with Medatech UK, the Priority partner.

Who it fits

• Finance directors and CFOs who want every invoice checked against the order before it posts
• Financial controllers and purchase ledger managers handling hundreds or thousands of invoices a month
• IT and IS managers on Priority ERP, Oracle Fusion Cloud ERP or Infor M3 who want a direct connection
• Companies of 200 to 5,000 employees, and larger groups that start with one subsidiary

Questions and answers

Is purchase invoice processing the same as vendor invoice processing?

Yes. UK teams say purchase invoice or supplier invoice, US teams say vendor invoice. The US view of the same flow is in vendor invoice processing.

What happens to an invoice with no purchase order?

It stops with a reason and the team decides. Nothing is entered without passing the checks you set.

Do suppliers have to send invoices differently?

No. They keep emailing PDFs as they do today. There is no portal to join.

How long does implementation take?

A typical DOConvert implementation takes about 10 business days. Most teams start with one inbox or one group of suppliers.

Does the data leave our environment?

No. The connection to the ERP is direct, and DOConvert can run in the cloud or on your own servers.
