OUTSOURCE CONSTRUCTION ACCOUNTING VS IN-HOUSE.
An in-house bookkeeper at $55,000/year plus benefits costs $76,000–$110,000 all-in annually. An outsourced fractional CFO engagement at $2,400/month costs $28,800/year — and includes job costing, WIP, cash forecasting, and monthly CFO meetings that an in-house bookkeeper cannot provide. The comparison is not just cost. It is what you get for the cost.
Most subcontractors think in-house accounting is cheaper. When you add employment costs, software, training, and turnover, outsourced typically wins on cost and consistently wins on capability. This page runs the full comparison so you can make the decision with real numbers.
WHAT IN-HOUSE ACCOUNTING ACTUALLY COSTS.
The salary is just the start. Here is the full loaded cost of an in-house bookkeeper for a $5M commercial subcontractor:
Compare to CFOS Executive Financial at $2,900/month for a $5M subcontractor: $34,800/year — which includes job costing, WIP schedule, 13-week cash forecast, monthly CEO Report, and monthly strategic meetings. An in-house bookkeeper provides none of those outputs.
The capability gap is the real cost. An in-house bookkeeper records transactions accurately. They do not calculate overhead rates, build 13-week cash forecasts, run cost-to-complete reports, or manage your collections process. The $40,000–$75,000 annual premium for in-house buys you proximity — not capability. Outsourced construction accounting brings construction-specific expertise, a system that runs every month, and no training curve on a new hire every 18 months.
THE CASES WHERE IN-HOUSE WINS.
High Transaction Volume Requiring Daily Attention
When you have 50+ employee timecards per week, daily material invoices across 10+ active projects, and multiple subcontractor payments running simultaneously, the sheer volume of transaction processing may justify a full-time in-house position. At this level — typically $15M+ revenue — the bookkeeping labor itself is a full-time job regardless of software automation.
Owner Preference for Daily Accessibility
Some owners want someone in the office available to answer financial questions on demand at any time of day. A fractional CFO engagement runs on a monthly cadence with defined response windows. If real-time daily financial access is non-negotiable, an in-house position is the right structure — though the capability gap still needs to be addressed separately through a fractional CFO or controller layer on top.
WHAT MOST $3M–$12M SUBS ACTUALLY NEED — LAYERED.
The right structure for most commercial subcontractors is a layered model — not purely in-house or outsourced:
This structure is more capable, more resilient to turnover, and typically $30,000–$50,000 cheaper annually.
