HOLOS Advisory, Tax & Accounting PLLC is a Phoenix-based accounting firm built for project-driven and professional service businesses — construction companies, consulting practices, engineering and architecture firms, creative teams, and law firms.

Professional service firms don’t look like other businesses on the books. Revenue arrives in stages rather than at the register. Your largest expense is people, and your largest asset walks out the door every evening. Work in progress, unbilled time, retainage, and multi-year engagements can hide the difference between a strong year and a break-even one until it’s too late.

Construction companies face a parallel challenge. Labor is usually your largest (or second-largest) expense, and your most valuable assets — experienced crews, project managers, and estimators — walk out the door every evening. Progress billings, retainage, job costing, and long project cycles can obscure true profitability until the job is already underwater.

That gap is where we work.

Different industries, same underlying problem: complex projects and billable work going in, profit coming out, and not enough visibility in between.
