Architect Invoice Template
Architectural projects span years and many distinct phases — schematic design, design development, construction documents, bidding, and construction administration. Milestone billing tied to each phase is the industry standard, and this template keeps that structure clean.

What to include on an architect invoice
Invoice by phase, not by hours. List the phase name and the percentage of the design fee it represents: 'Schematic Design — 15% of design fee — $X' or 'Construction Documents — 40% of design fee — $X.' For hourly work — additional services outside the base scope — list the service, hours, and rate: 'Additional design services — material research, 4 hours @ $X/hr.' Reimbursable expenses (printing, model materials, consultant fees, permit application fees) should appear as separate line items at cost, with receipts. Include your project number and the client's project address on every invoice for clear record-keeping.
How architects price their services
Architectural fees are commonly structured as a percentage of construction cost (8–15% for residential, 5–12% for commercial, higher for complex or custom work) or as a fixed fee agreed upfront. Hourly billing ($100–$300/hr depending on experience and firm size) is used for smaller projects or additional services outside scope. The AIA phases — Schematic Design, Design Development, Construction Documents, Bidding/Negotiation, Construction Administration — provide natural billing milestones. Ensure clients understand that your fee covers design and documentation; construction costs are entirely separate.
When to invoice for architectural services
Invoice at the completion of each design phase before moving to the next — this is both standard practice and good cash flow management. For long construction administration phases, monthly billing is appropriate. Reimbursable expenses should be invoiced monthly alongside your phase invoices. Never begin the next phase until the current phase invoice is paid.
Getting paid reliably as an architect
Use AIA contract documents (B101 for residential, B103 for larger projects) — they're industry-standard, protect both parties, and define fee, scope, and billing milestones clearly. For initial consultations, determine upfront whether this is a free conversation or a billable meeting. Keep a contemporaneous log of site visits and meetings during construction administration; disputes are rare when you have detailed records.
Frequently asked questions
Should I charge for revisions beyond the agreed scope?
Yes — AIA contracts define what's included in each phase and what triggers additional services. Document client-requested changes and issue additional service invoices before doing the work.
How do I invoice for permit coordination?
Permit application fees are a reimbursable expense (pass through at cost). Your time spent preparing and coordinating permit applications is a professional service — bill it hourly or include it in your standard fee, and specify which applies in your contract.
Can I withhold construction documents if a client doesn't pay?
This varies by state and contract type. The AIA B101 generally allows you to suspend services for non-payment after providing written notice. Consult your professional organization and a lawyer for your jurisdiction.
