Frequently asked questions
How do architects bill their clients?
Most architects bill in three ways: percentage of construction cost, fixed fee by phase, or hourly. Larger projects usually combine phase billing with reimbursables like printing and travel.
What is the AIA billing format?
AIA G702/G703 is the industry-standard payment application for construction — architects usually adapt a similar phase-percent format for professional service invoices.
Do architects charge sales tax?
In most US states architectural services are exempt from sales tax, but reimbursables like prints may be taxable. Confirm with your state.
