Invoice Generator for Architects
Architectural fees are billed by phase against a percentage of construction cost — the invoice must show which phase and what percentage is complete.
How architects should structure their invoices
- Show the phase and percentage complete; AIA-style billing is audited against deliverables, not hours.
- Reimbursables (printing, travel, consultants) belong in their own section.
- Additional services must be pre-approved in writing and invoiced separately.
The invoice above already contains the line items most architects bill for. Adjust the rates to your own, delete what does not apply, and add anything specific to your engagement.
What a architect invoice must include
- A unique, sequential invoice number — never reuse or skip numbers.
- Your business name and address, plus your tax or registration number if you have one.
- The client's name and address, and a purchase order reference if they use one.
- Each service on its own line with quantity and rate, so the total is auditable.
- Tax shown separately with the rate, and the total clearly stated.
- Payment terms and the due date — not only in your contract.
Architects invoicing questions
How are architect fees structured?
Percentage of construction cost (typically 5-12%), fixed fee, or hourly. Percentage is standard for buildings.
When do I bill each phase?
At phase completion or monthly progress billing. Never bill a phase before its deliverables are issued.
What are additional services?
Anything outside the agreed scope — redesigns after approval, extra site visits, code changes. Invoice separately, always.
