Purchase order automation: close the gaps the margin leaks through.

Between the quote you won and the invoice you finally sent sits a chain of paperwork: the PO, the delivery docket, the supplier invoice. Every unmatched link in that chain is money leaking quietly. We automate the raising, the matching and the catching.

What is purchase order automation?

It is a system that raises purchase orders from the job instead of from memory, reads the delivery dockets and supplier invoices as they arrive, matches all three against each other, and flags anything that does not line up. Ordered, received and charged finally agree, on every order, without anyone doing the checking by hand.

Most businesses have a PO process on paper and a "just order it" culture in practice. The fix is not another policy memo. It is making the PO the easiest way to order something, which is an automation problem, not a discipline problem.

The paperwork chain, and where it snaps

Every job runs the same chain: quote, job, purchase order, delivery docket, supplier invoice, your invoice. Each link is usually fine. The gaps between the links are where the money goes, because nobody has time to reconcile one link against the next.

LinkWhat goes wrong todayWhat the automation does
Job to POMaterials ordered by phone, no PO, no recordRaises the PO from the job, in seconds, from any phone
PO to docketDockets in glove boxes, deliveries never confirmedReads the docket, matches it to the PO, chases what is missing
Docket to invoiceInvoices paid on trust because checking takes hoursChecks every line: quantity, rate and job, and flags the differences
Cost to your invoiceVariations delivered but never billed onSurfaces every cost with no matching revenue line

What is three-way matching, in plain words?

The PO says what you ordered. The docket says what arrived. The invoice says what you were charged. Three-way matching just means checking that all three agree before money moves. Every accounts textbook recommends it, and almost nobody at trades-business scale does it, because by hand it takes hours nobody has.

That is precisely why it automates so well. The checking is pure rules and reading, the two things AI does tirelessly. The judgement, deciding what to do about a mismatch, stays with your people, who now spend minutes on decisions instead of hours on detective work.

Where does the margin actually leak?

Three places, in our experience. Price creep: supplier rates drift up invoice by invoice while your quotes still assume last year's numbers. Ghost quantities: charged for ten, received eight, nobody counted. And uncaptured variations: extras that got delivered to the job but never made it onto your invoice to the client.

Each leak is small on its own, which is exactly why humans miss them and systems do not. The rates the system checks against are the same rates your quoting runs on, which is why this build pairs so naturally with quote automation: when the buy price moves, the sell price finds out the same week.

Ask any builder where the margin went and you will hear the same story. It leaked out between the quote and the final invoice, one unmatched docket at a time.

What breaks purchase order automation in practice?

Retro-POs and glove-box dockets. If people order first and paper up later, the matching has nothing to match against, and if dockets never leave the ute, the middle of the chain is blind. Both are habit problems, and both get solved the same way: make the right way the easy way.

Raising a PO has to take less effort than not raising one: a message from a phone on site, answered in seconds. Dockets have to be a photo, not a filing task. We design for the site crew you actually have, not the administratively gifted one nobody has, and the reading side of that is our bread and butter: see document processing.

When should you not automate purchase orders?

When you barely buy anything, when a single supplier account already reconciles itself through their portal, or when your purchasing is so simple that a mismatch has never cost you real money. Automation earns its keep on volume, on multiple suppliers, and on job-based buying, which is where the gaps multiply.

The heavy-buying industries we work with, mining services, construction, plant hire, live on exactly that kind of purchasing. If your month-end includes a mystery pile of unmatched dockets, the audit will put a number on what the chain is costing you.

How we build it

Make raising a PO effortless first. The matching only works if the chain exists.

We map how buying really happens

Who orders, how, and where the paperwork dies. The gap between the official process and the real one is where the build starts.

We make the PO the easy path

Ordering through the system takes seconds from a phone on site, raises the PO and books the cost to the job. No forms, no office trip, no excuse.

We switch on the matching

Dockets and invoices get read as they arrive and checked against the PO, line by line. Differences go to a person with everything side by side.

The numbers start talking

Committed costs per job in near real time, price creep caught in the week it happens, variations surfaced before invoicing. You own all of it.

Common questions

Does it work with MYOB, Xero and our job system?

Yes. The purchase orders live in the systems you already run, and the automation raises, matches and flags around them. Your accounts team keeps their books, your project managers keep their job system, and the re-typing between the two disappears.

Do our suppliers have to change anything?

No. They keep sending dockets and invoices exactly as they do now. The automation reads what arrives in whatever format it arrives in and does the matching on your side. If a supplier never quotes references, the system copes by matching on the details instead.

What happens when something does not match?

A person sees it, fast, with the PO, the docket and the invoice side by side and the difference highlighted. The automation never quietly approves a mismatch and never quietly rejects one either. It does the checking. Your people do the deciding.

Can it help with job costing?

Significantly. Once every order is a PO raised against a job, you can see committed costs in close to real time instead of finding out at month end. Jobs that are quietly going over budget stop being a surprise in the accounts and start being a Tuesday conversation.

What happens to our purchasing data?

It stays in your own systems and accounts. We build on OpenAI, Anthropic and Microsoft models under business terms, which means your data is not used to train public models. The full detail is on our security page.
