Frequently Asked Questions

Common questions about construction procurement hub.

What is procurement in construction?
Construction procurement is the process of planning, approving, ordering, receiving, and paying for labour, plant, and materials. It is not just buying things. Good procurement control links supplier orders to projects, cost codes, budgets, deliveries, and invoice approval.
Why are purchase orders important in construction?
Purchase orders create a formal commitment before money is spent. They help contractors control who can approve spend, where the cost sits, what was ordered, and what value has been committed before invoices arrive.
What is a goods received note?
A goods received note, or GRN, records what was actually delivered against a purchase order. It gives you evidence of quantity, timing, shortages, and quality issues before supplier invoices are approved.
What is three-way matching?
Three-way matching means checking the purchase order, the goods received note, and the supplier invoice against each other before payment. It is one of the simplest ways to stop overbilling, duplicate invoices, and payment disputes.
Can small contractors benefit from procurement controls?
Yes. Smaller contractors often feel procurement pain earlier because a few uncontrolled orders or invoices can damage margin quickly. Even simple PO, GRN, and invoice checks create better cost visibility and fewer surprises.
