Supplier (Materials Supplier)
A construction materials supplier sells building goods like timber, tiles, and fixtures, rather than doing on-site labour. Suppliers invoice for goods and get paid separately from labour subcontractors.
Definition
A construction materials supplier is a business that sells building goods to a builder or subcontractor: timber, tiles, plasterboard, fixtures, fittings. They supply the materials that go into the house. They do not perform the on-site labour that installs them.
That is the line. A subcontractor brings labour and trade skill to site. A supplier delivers goods to the gate and invoices for them. Many trades are both, but on any given job the role is defined by what is being paid for: labour or materials.
Why it matters
Materials are often the biggest single cost on a job. If a supplier is not paid, deliveries stop and the build stalls. Suppliers also sit in a different spot to labour subbies. They usually extend trade credit, so they carry the cost for weeks before any invoice is paid. Knowing whether you are a supplier or a subcontractor on a given job tells you how, and when, you get paid.
How it works in practice
A supplier delivers goods and issues an invoice, often a monthly statement covering many deliveries. Payment terms are usually trade credit: 30 days, sometimes 60. The supplier funds the materials up front and waits.
On a BuildFair job, the cost of materials a builder buys on a subcontractor's behalf is set off against that sub's payable pool. So if the builder pays for the sub's plasterboard, that amount comes off what the sub is owed. The sub gets paid for labour, not for materials someone else already covered.
There is no public supplier subscription yet, so suppliers do not log in. Instead, you email your invoices and statements to the builder's or subcontractor's BuildFair alias. The document lands as a draft against the right project, ready for the builder or subcontractor to check and approve.
Timing differs from labour too. Once an invoice is approved, subcontractor and supplier payments release on a fixed 7-day clock from approval. The ledger records the payment straight away, and the bank send follows after that calendar-day hold.
Common misconceptions
A supplier is just a subcontractor who sells things
No. A subcontractor is paid for labour and trade work on site. A supplier is paid for goods delivered. The payment paths and protections differ, so the distinction matters on every claim.
Suppliers get paid the same way and time as labour subbies
Not quite. Suppliers typically run on trade credit, carrying the cost for 30 to 60 days before invoicing. And materials a builder buys for a sub are set off against that sub's pool, so the same dollars are not paid twice.
Suppliers need a paid account to use BuildFair
No. There is no public supplier subscription. You email invoices and statements to the builder's or subcontractor's BuildFair alias and they land as drafts for approval, with no login required.
Materials and labour come out of the same pot with no order
On a BuildFair job they are tracked apart. Materials the builder pays for a sub reduce that sub's payable pool, so the sub is paid for labour, not for goods already covered.
