Invoice Template for Architects
Architects bill across multiple phases — schematic design, design development, construction documents, and construction administration. Whether you charge hourly, a percentage of construction cost, or fixed fees, your invoice must clearly reflect the phase, scope delivered, and any reimbursable expenses.
Key takeaways
- Include all essential details: your info, client info, invoice number, itemized services, and payment terms
- Be specific about deliverables — vague line items lead to payment disputes
- Set clear payment terms with a due date and late fee policy
- Follow up promptly when payments are overdue — use a tracking system
What to Include on Your Architects Invoice
- Firm name, principal name, and contact information
- Client name, project name, and project address
- Invoice number and billing period
- Phase of services (SD, DD, CD, CA) with description
- Hours by team member and rate, or percentage applied
- Reimbursable expenses (printing, travel, consultants)
- Contract or fee agreement reference

Common Architects Invoicing Mistakes to Avoid
- Not tying invoice to the AIA contract phases — clients need to reconcile with contract
- Block billing without task breakdown — clients and GCs expect detail
- Failing to separate reimbursables from professional fees
- Not tracking percentage of construction cost as project budget changes
- Invoicing too infrequently — cash flow suffers on long projects
How Architectss Get Paid Faster
- Reference the AIA contract number and billing schedule on every invoice
- Break down hours by phase and team member for transparency
- Invoice monthly or at phase completion, whichever comes first
- Track reimbursables separately and attach receipts when required
- For percentage fees, show the construction value and percentage applied
Tracking invoices manually is error-prone. Track your outstanding invoices with a visual Kanban board, built-in chase history, and a plan your follow-up timeline tool.
