These are contracts for all construction work and the supply of related goods and services that is not domestic building work. For example:

• Civil contracts

• Contracts with a builder (residential or commercial)

• Contracts with a commercial building owner or commercial tenant

• Domestic building contract under $3,300 (including materials, labour and GST)

• Contracts with owner-builders

• Contracts with federal, state, territory or local government

From 1 September 2025, TradeBox is rolling out to its existing and new customers the Construction Contract, which is a replacement of its earlier version, the Commercial Trade Terms.
