How is this different from generic procurement automation?

This build is specifically about the purchase order lifecycle: request, value based approval, issuing the PO to the supplier, goods receipting, and three way matching the PO, the receipt and the invoice before payment. Broader procurement covers sourcing, supplier selection and contracts as well. If you mainly need to get control over POs, approvals and matching, this is the focused, faster to deploy answer.

What is three way matching and why does it matter?

Three way matching compares three documents before an invoice is paid: the purchase order (what you agreed to buy), the goods receipt (what actually arrived) and the supplier invoice (what you are being billed for). When all three agree on items, quantities and prices within your tolerances, the invoice proceeds to payment. When they do not, the invoice is held. It is the single biggest control for stopping overcharges, paying for goods never received, and quantity errors.

Can approvals route based on the value of the purchase?

Yes. Approval routing is driven by the rules you set, commonly by dollar value and cost centre, and matched to your delegation matrix with the relevant budget visible. Small requests can auto approve under a threshold, larger ones escalate to the appropriate approver, who can act from their phone. No PO is issued without the approval your policy requires.

Does it integrate with Xero or MYOB?

Yes. POs and matched bills can be recorded in Xero or MYOB with correct GST, coding and the PO referenced, ready for the payment run. The automation reads and writes through the standard accounting API on a dedicated service connection, so your existing setup and reports continue unchanged. If you run a separate inventory or ERP system, we confirm the integration at discovery.

What happens with partial deliveries and back orders?

Receipting handles full, partial and over deliveries against the PO, so the goods receipt always reflects what actually arrived. The three way match then works on received quantities, meaning an invoice for items not yet delivered is held until they are. Back orders and split deliveries are tracked against the original PO, so nothing is paid ahead of receipt and nothing is lost.

How long until we are live, and is it disruptive?

Most builds go live in 3 to 6 weeks. We reduce disruption by piloting on one department, site or spend category first. Real purchases flow through the new process while the rest of the business carries on as is, the tolerance and routing edges surface, and only once it is running cleanly do we widen across the business and retire the old email and spreadsheet method.

What does a realistic return look like?

For a business raising 50 to 300 POs a month by hand, teams typically recover 6 to 12 hours a week of chasing approvals, typing POs and reconciling invoices, and recover 1 to 4 percent of spend by catching mismatches, price creep and off contract buying. Most builds pay back within the first few months, and purchasing moves from firefighting to genuine control.

For Australian businesses with email and spreadsheet purchasing

Purchase Order Automation for Australian Businesses

Purchasing run on email threads and a shared spreadsheet is where budget leaks and unmatched invoices live. Someone requests a buy, an approval gets lost, a PO never actually gets issued, goods arrive without a receipt, and the invoice is paid without anyone checking it matched what was ordered. PO automation puts a clean, controlled flow around all of it.

We give you a structured purchasing flow: requests captured, approvals routed by value, the PO issued to the supplier, goods receipted on arrival, and a three way match of the PO, the receipt and the supplier invoice before anything is paid. Clean matches flow through. Mismatches are held and surfaced, so you stop paying for what you did not order or did not receive.

Why Automate Purchase Orders (Not Just Keep the Spreadsheet)

Four reasons Australian businesses move purchasing off email and spreadsheets onto a controlled PO flow with three way matching.

Every buy starts as a captured request

Purchase requests come in through a simple form or email and are captured with the item, quantity, supplier, cost centre and reason, instead of living in a chat thread. Nothing gets bought without a request on the record, which is where budget control and clean reporting begin.

Approvals route by value and budget

Requests route to the right approver based on the dollar value and cost centre, matched to your delegation matrix, with the relevant budget visible. Small buys can auto approve under a threshold, larger ones escalate. The approval is enforced, not an optional email someone can skip.

POs actually get issued to suppliers

Once approved, a properly numbered purchase order is generated and issued to the supplier automatically, with the agreed items, quantities and prices. No more approved buys where the PO never got sent, and no more suppliers quoting "no PO, no order" back at you.

Three way matching before you pay

When the supplier invoice arrives, the automation matches it against the PO and the goods receipt: right items, right quantities received, right prices. Clean matches proceed to payment. Mismatches (over quantity, price creep, never received) are held and surfaced, so you stop paying for what you did not order or get.

How Purchase Order Automation Works

Six stages from request to matched and ready to pay, automated for clean cases and surfaced for exceptions.

Request captured

Request intake

Purchase requests captured through a form or email with item, quantity, supplier, cost centre and reason. Every intended buy is on the record before any commitment is made, so nothing slips through as an untracked purchase.

Routed by value

Budget and approval routing

Requests route to the right approver based on value and cost centre, matched to your delegation matrix, with budget context shown. Small requests can auto approve under a threshold, larger ones escalate. Approvers act from email or a mobile view.

PO sent to supplier

Issue the PO

On approval, a numbered purchase order is generated with the agreed items, quantities and prices and issued to the supplier automatically. A copy is recorded against the request and posted to your accounting or inventory system.

Receipt recorded

Goods receipting

When goods arrive, receipting is captured (full, partial or over delivery) against the PO. Short and over deliveries are recorded accurately, so the receipt reflects what actually turned up, not what was ordered.

Matched or held

Three way match

The supplier invoice is matched against the PO and the goods receipt on items, quantities and prices. Clean matches within tolerance proceed. Mismatches are held with the exact discrepancy attached, ready for a person to resolve.

Ready for payment

Approve to pay and post

Matched invoices post as bills to Xero or MYOB, coded and with the PO referenced, ready for the payment run. The full request, approval, PO, receipt and match history is kept for audit.

How We Keep Purchase Order Automation Safe and Controlled

Approvals enforce your delegation matrix

Approval routing and thresholds match your authority matrix. No PO is issued and no invoice is approved for payment without the right person signing off, and the rules for what can auto proceed are set by you. The control is stronger than email approvals, never weaker.

Mismatches are held, never auto paid

An invoice that does not match the PO and receipt on items, quantities or price is held with the exact discrepancy and routed to a person. The default is always to stop and ask, so you never pay for goods you did not order, did not receive, or were overcharged for.

Matching tolerances are agreed, not assumed

Small, expected variances (rounding, agreed price tolerance, part deliveries) are handled by tolerances you set, so genuine mismatches stand out and trivial ones do not clog the queue. We agree these tolerances with finance during build.

Your accounting or ERP stays the source of truth

Suppliers, POs, receipts and bills live in your accounting or inventory system, not a parallel tool. The automation reads and posts to that system so there is one set of records. We confirm the authoritative system at discovery.

GST and supplier details stay compliant

POs and bills carry correct GST and supplier ABN details, and posting follows the treatment your bookkeeper expects. We confirm tax handling for your supplier mix, including any imports, during build so your accounts and BAS stay clean.

Full audit trail from request to payment

Every purchase keeps a record: who requested, who approved, the PO issued, what was receipted, how the match resolved and when it was paid. Defensible for finance, auditors and any supplier dispute.

How Yes AI Delivers Purchase Order Automation
