What Does a Construction Accountant Do?

Updated July 2026

A construction accountant tracks money by project, not just by month. A retailer closes the books and knows how the business did; a contractor can close the books perfectly and still not know whether the $40M hospital job is making or losing money. Construction accounting exists to answer that second question — continuously, project by project — and everything distinctive about the role flows from it.

The core responsibilities

Job costing

Every dollar a contractor spends gets coded to a job and a cost code (labor, materials, subcontracts, equipment) so actual costs can be compared to the estimate line by line. The construction accountant owns this coding discipline: setting up cost structures when a job starts, catching miscoded invoices, and reconciling committed costs — signed subcontracts and purchase orders — against budgets. Bad job cost data doesn’t just annoy the accountants; it misleads the project team about margin until it’s too late to fix.

The WIP schedule

The work-in-progress schedule is construction accounting’s signature document. For every active job it compares cost incurred to total estimated cost, computes percent complete, and derives earned revenue — surfacing overbillings and underbillings. Banks and bonding companies read the WIP before they read anything else, because it reveals both project health and whether management’s estimates can be trusted. Preparing it monthly, and explaining the gain/fade on each job, is often the project accountant’s or controller’s most scrutinized deliverable.

Revenue recognition (percentage of completion)

Contractors generally recognize revenue over time under ASC 606 — in practice, the cost-to-cost percentage-of-completion method. Revenue follows the WIP math above, which means revenue is only as accurate as the cost forecasts feeding it. Construction accountants spend real time with project managers pressure-testing estimates-at-completion.

Progress billing (AIA G702/G703)

Commercial work is billed monthly against a schedule of values using AIA forms G702 and G703: percent complete per line item, stored materials, less retainage — the 5–10% the owner withholds until completion. The construction accountant assembles these pay applications, tracks retainage receivable, and chases the certified approvals that release payment. On the payable side, the same process runs in reverse with subcontractors, including collecting lien waivers before checks go out.

Certified payroll and compliance

On public projects, contractors file weekly certified payroll reports (form WH-347) proving workers were paid prevailing wages under Davis-Bacon or state equivalents. Add union fringe benefit reporting, multi-state tax withholding for traveling crews, and 1099 compliance for small trade partners, and payroll alone is a specialty within the specialty.

How it differs from general accounting

A typical month

Weeks one and two revolve around billing: assembling pay applications, reconciling subcontractor invoices against their contracts, collecting lien waivers. Mid-month brings job cost review with project managers — where are we against budget, what change orders are unapproved, what’s the updated cost to complete. Month-end is close week: WIP schedule preparation, over/under billing entries, and reporting that goes not just to management but often to the bank and the surety.

Career path and breaking in

The usual ladder runs AP/payroll clerk → staff or project accountant → senior project accountant → assistant controller → controller → CFO. Two things accelerate it: owning a WIP schedule end-to-end, and deep skill in one construction ERP. Coming from general accounting? Target project accountant roles at mid-size general contractors — they hire for aptitude and train the construction specifics — and learn job costing vocabulary before the interview. The CFMA’s CCIFP credential is the industry-recognized certification once you’re committed.
