Receiving, deliveries and invoice matching,
the check before money leaves.

Receiving is the discipline of checking what actually arrives on site against what was ordered, at the moment it lands. Invoice matching is the same discipline applied to the money, holding every supplier invoice against the commitment it belongs to before it is paid. Together they are the final two steps of the commitment workflow described in the procurement reference, and they are the only steps that verify anything. Everything upstream of them creates commitments; these two check that reality and the paperwork agree.

Defined precisely, receiving produces the receipt record (a checked, annotated, signed delivery docket tied to its purchase order), and matching is the comparison of three documents that describe the same transaction. The order says what was agreed, the docket says what arrived, and the invoice says what the supplier wants to be paid. When all three agree, payment is safe. When they do not, the difference is either a credit the builder is owed or a cost increase nobody approved, and matching is the only mechanism that tells you which.

Why it matters

On a residential job most of the contract sum flows out through suppliers and subcontractors, in dozens of deliveries and hundreds of invoices, each individually too small to investigate and collectively the whole cost of the build. Suppliers invoice above ordered rates, loads arrive short, substitutions happen in good faith, and arithmetic goes wrong, none of it dramatic and all of it money. Receiving and matching are how those leaks are caught while they are still correctable. Every check skipped is not saved effort; it is a decision to pay whatever arrives.

In the procurement workflow, receiving and matching begin where committing ends. The purchase order workflow creates the baseline; receiving verifies the goods against it during construction, and matching verifies the money against both. That position makes this the seam between two versions of the job's cost. The committed position (what the purchase orders and subcontracts add up to, covered in committed costs) is a forecast built from agreements; the paid position is a fact built from bank transactions. Matching is the only process that reconciles them line by line while the difference can still be acted on.

Downstream, the matched and approved invoice does two more jobs. It lands as an actual cost against the job's cost codes, which is what makes cost reporting mean anything, and it carries the real market rate back to estimating, which is what keeps the next job's pricing honest. An unmatched invoice does neither; it just moves money.

The blunt observation experienced operators make is this. The site signs for whatever lands, and accounts pays whatever arrives, and unless somebody deliberately connects those two facts, the gap between them is real money leaving the business. Neither person is doing anything wrong. The supervisor signing at the gate is getting a truck unloaded with a crane booked for eleven; the bookkeeper paying at month end is clearing a queue. The leak lives precisely in the fact that each of them is trusting a check they assume the other one made.

Builders who hold margin run the loop closed, and the habit has a rhythm to it. The docket is attached to its purchase order the day of the delivery, not found in a ute at month end. The credit for a short load is chased the week it happened, while the supplier can still check the run and the evidence is a photograph and an annotated docket, not chased at reconciliation three months later when the claim is one person's recollection against a signed clean docket. And every matched invoice is treated as market data as well as a bill, because the actual rate paid is the number that corrects the cost database the next estimate will price from.

Where software fits the workflow

Done by hand, the match is the admin that eats evenings. Someone digs out the purchase order, finds the docket if it made it back, re-reads the invoice and compares the three by eye, for every invoice, on every job, usually after dinner. This is the work that changes when the system already holds the order and the receipt. In VIABUILD, supplier invoices route to a dedicated accounts inbox where Oryn™ reads each invoice and matches it against the purchase order, flagging the lines that do not agree for a person to decide. Approval happens from a phone, against defined limits, so the person with authority is not a desk-bound bottleneck. Nothing is paid on the system's say-so; the builder decides every flagged line, and the audit trail records both. The wider payables workflow around this sits in the accounts payable guide.

The matching discipline sits inside Australian tax and payment rules that change over time and differ by state. The points below are labelled by evidence class and are general information, not tax or legal advice; confirm the current requirements with the source named before relying on any of them.

• Government guidance. The ATO sets out what a document must contain to be a valid tax invoice for GST purposes, including the supplier's identity and ABN, the date, a description of what was supplied and how the GST is shown, with additional requirements above certain invoice values. GST credits depend on holding valid tax invoices, which makes the validity check a matching step rather than a BAS step. Confirm the current requirements at ato.gov.au.
• Common practice. Builders report that subcontractor invoices and remittances regularly carry GST or calculation errors, creating short payments, corrections and re-checking. In practice, once one trade has shown calculation errors, everything from that trade gets manually re-checked, which is pure administrative drag and a reason the arithmetic check belongs in the standard match for everyone rather than in a trust decision per trade.
• Legislation. Security of Payment legislation in each state and territory sets timeframes for responding to payment claims from subcontractors and suppliers. A disputed invoice from a claimant under those Acts needs the dispute raised formally within the statutory timeframe, not the invoice left sitting in a queue. See security of payment in Australia and confirm the rules for your jurisdiction.
• Common practice. Supplier trading terms often include retention of title, meaning the supplier may retain ownership of delivered materials until they are paid for. Receiving a load does not settle whose goods they are; the terms you signed do, which is one more reason the supply terms deserve reading before the account is opened.

Illustrative only, not a benchmark. A purchase order commits 40 sheets of reinforcement mesh at $85 a sheet, $3,400 plus GST. The truck arrives with 36 sheets, the docket says 40, the driver is on the clock, and the site signs clean. Two weeks later the invoice arrives for 40 sheets at $92 a sheet, $3,680 plus GST, priced from the supplier's updated price list. Unmatched, it gets paid. The job has now paid $3,680 for $3,060 worth of mesh at the agreed rate, absorbed a price rise nobody approved, and will buy the missing four sheets again at the new price. Roughly $620 has left the business on one routine delivery, and nothing anywhere shows it happened.

Run closed, the same delivery goes differently. The count finds 36 sheets, the docket is marked before signing and photographed, and the credit claim goes in that week. When the invoice lands, the match flags both variances, quantity against the docket and rate against the order. The supplier issues a credit for the shortfall and a corrected invoice at the PO rate, or the builder consciously accepts the new rate with the record updated. Either way the decision was made by the builder, the job's cost position stays true, and the real mesh rate reaches the cost database before the next estimate prices from the old one.

Delivery docket (the supplier's record of what was delivered), receipting (checking and recording what arrived against the order), subject to check (a signature qualified because the load could not be counted on the spot), two-way match (invoice held against purchase order), three-way match (invoice against order against receipt), price variance (a billed rate above or below the agreed rate), credit note (the supplier's document reversing part of an invoice), tax invoice (a document meeting ATO requirements for GST purposes), approval delegation (named approvers with limits and a nominated backup). The wider vocabulary lives in the construction glossary. From here, the natural next article is aligning procurement with the schedule, where the question shifts from whether the right goods arrived to whether they arrived at the right time.
