Architectural services span multiple stages — from initial briefing and concept design through to planning submission, technical drawings, and construction oversight. This free architect invoice template is structured around RIBA (or equivalent) work stages so clients understand exactly what phase they're paying for.
Architectural fees are typically charged as a percentage of construction cost or as fixed fees per stage. Structuring your invoice around defined stages — Stage 1: Concept Design, Stage 2: Developed Design, etc. — gives clients a clear roadmap of where their fee is going.
Disbursements in architecture — planning application fees, structural engineer fees, consultant costs — should be listed separately and passed through at cost. Large consultant fees should ideally be agreed in advance and referenced in your project agreement.
A professional architecture invoice should include all standard invoice elements — invoice number, dates, contact details, and payment terms — plus line items specific to your work. Here are the most common line items for architecture invoices:

✦ Open Invoice GeneratorA percentage of construction cost (typically 5–15%) or fixed stage fees are the two most common approaches. Percentage fees align your interest with the project budget; fixed fees give clients cost certainty.
Planning application work is usually billed as a fixed fee stage. The planning application fee itself (paid to the local authority) is a disbursement that should be listed separately and passed through at cost.
Stage payments tied to deliverable milestones are standard. Each stage invoice is raised when the stage deliverable is completed and approved — not at a fixed point in the calendar.
