What are progress payments in Australian building contracts?

Progress payments divide the total contract price into staged payments released as construction reaches specified milestones. Rather than paying the full amount upfront or waiting until practical completion, the owner releases funds at key stages-such as after site establishment, concrete slab, frame completion, or lock-up-as outlined in the building contract.

This structure protects both parties. Builders receive funding progressively to cover labour, materials, and subcontractor costs as work advances, improving cash flow management on site. Owners retain money until work reaches each agreed stage, reducing financial risk if the project stalls or quality falls short. The schedule and timing of progress claims are typically set out in the contract terms, though they may follow industry standards or state-based building legislation requirements.

Progress payments are standard practice in the team residential construction, particularly for custom homes where projects run over many months. They're different from fixed lump-sum payments or retention arrangements, where a percentage is held until final completion. When engaging a custom home builder, understanding how progress payments will be triggered and processed is an important contract negotiation point, as timing and verification processes vary between builders and project types.
