At what revenue level should a subcontractor hire in-house?

Most $1M to $12M subcontractors are better served by outsourced construction CFO than in-house controller. Above $12M the volume may justify the full-time cost. Below $12M, outsourcing to a construction-specific firm wins on cost and expertise.

What happens when an in-house controller quits?

3 to 6 month gap, $15K to $40K in recruiting and transition costs, and loss of institutional knowledge. Outsourced accounting eliminates turnover risk entirely.

Can SPM work alongside an in-house bookkeeper?

Yes — this is the hybrid model. The bookkeeper handles daily transactions; SPM handles close, WIP, CEO Report, billing, and CFO advisory. SPM trains the bookkeeper on job cost standards and holds them to the close schedule.

FINANCIAL STRUCTURE — BUILD VS BUY

IN-HOUSE ACCOUNTING VS OUTSOURCED. THE REAL COST COMPARISON.

QUICK ANSWER

A full-time controller costs $80K to $120K annually plus benefits, payroll taxes, and turnover risk. An outsourced construction accounting firm at the right level costs $24K to $72K annually — less than half, with construction-specific expertise included. But the comparison is not purely about cost. It is about what each model actually delivers and whether the business is at the stage where in-house control is worth the premium.

COST IS ONE FACTOR. CONSTRUCTION EXPERTISE IS THE OTHER.

What Each Model Actually Delivers

IN-HOUSE CONTROLLER — WHAT YOU GETA full-time employee dedicated to your business. Available for same-day questions. Can attend internal meetings in person. Builds institutional knowledge of your specific contracts and GC relationships over time. Best suited for companies above $12M where volume and complexity justify the cost and where the construction CFO advisory function is a separate engagement.

SPM OUTSOURCED — WHAT YOU GETFractional CFO plus controllership plus bookkeeping coordination in one engagement. Construction-specific expertise across 24 active trade specializations. Monthly CEO Report, weekly cash forecast, billing calendar, CO tracking, WIP reconciliation, and monthly accountability meeting. No turnover risk, no benefits overhead, no training lag. And Josh was a PM and master electrician — which means the advisory function understands the field, not just the spreadsheet.

THE HYBRID MODELMany SPM clients retain a part-time bookkeeper for daily transaction entry and coordinate that bookkeeper with SPM's oversight and close process. This captures the benefits of someone who knows the business day-to-day while adding the construction CFO layer on top. For $3M to $8M subcontractors, the hybrid often outperforms both pure models on cost and quality simultaneously.

THE DECISION LOOKS DIFFERENT BY COMPANY PROFILE.

$1M–$3M Subs: The Spreadsheet Cliff

Under $3M, in-house usually means the owner's spouse or a part-time bookkeeper — fine until job costing, WIP, and pay-app discipline exceed what evenings can carry. The outsourced case here isn't cost savings; it's getting construction-specific competence the size of business can't hire. A $60K bookkeeper who doesn't know construction is more expensive than they look.

$3M–$8M Subs: The Controller Question

This is the range where owners price a full-time controller — $110K–$160K all-in — and discover the honest comparison. An outsourced construction-specific function delivers the same close, WIP, and reporting from roughly $34K a year, with no recruiting risk, no turnover gap, and trade expertise no generalist hire brings. The in-house case has to beat that by a wide margin to make sense.

$8M–$12M Subs: The Hybrid Model

At this size, an in-house AP/payroll clerk plus outsourced controllership and CFO advisory is often the right architecture — transactional volume handled internally at clerk cost, judgment and reporting handled by specialists. Paying controller wages for AP work is the common mistake this range makes.

Family-Run Books: The Hardest Conversation

When a spouse or family member runs the books, the comparison stops being financial. The honest framing: subcontractor accounting is genuinely complex — WIP, retainage, certified payroll — and the family member was never given the tools. Outsourcing isn't a judgment of them. One SPM client's wife had been doing the books after hours for years; the system change gave the family their evenings back and the business its visibility.

WHAT THE NUMBERS SAY IN PRACTICE.

$110K–$160K

The real all-in controller cost. Salary is the visible number — $85K–$120K for a construction controller in most markets. Add payroll taxes, benefits, PTO, software seats, recruiting fees, and the 6-month productivity ramp, and the all-in lands at $110K–$160K. Against an outsourced Executive Financial engagement from $34,800/year, the in-house premium runs $75K–$125K annually.

6 Months

The turnover hole nobody prices. When an in-house controller quits, the close stops, the WIP goes stale, and the replacement search runs 3–6 months — followed by another ramp. One departure can cost a year of financial continuity. An outsourced function doesn't resign, doesn't take FMLA during bid season, and doesn't hold the books hostage in one person's head.

60 Days

To full function, either way you start. SPM onboards companies coming from in-house chaos and from failed outsourcing alike: books migrated back to the start of the last taxable year, job costing rebuilt, close cadence installed — fully operational in 60 days. The comparison isn't just cost. It's how fast the function actually works.

Frequently Asked Questions

Most subcontractors in the $1M to $12M range are better served by an outsourced construction CFO firm than by an in-house controller. Above $12M, the volume and complexity often justify the all-in cost of an in-house controller, especially when combined with an outsourced CFO advisory layer. Below $12M, the cost and expertise arguments favor outsourcing to a construction-specific firm.

The company loses institutional knowledge, faces a 3 to 6 month gap while recruiting and onboarding a replacement, and typically spends $15K to $40K in recruiting and transition costs. The replacement rarely has the same construction expertise as their predecessor if they were strong. Outsourced accounting eliminates turnover risk — the relationship and the institutional knowledge stay with SPM regardless of who does the day-to-day work.

Yes — this is the hybrid model that works well for most $3M to $8M clients. The bookkeeper handles daily transaction entry, payroll, and AP. SPM handles the close process, WIP reconciliation, CEO Report, billing calendar, and CFO advisory. SPM trains the bookkeeper on job cost entry standards and holds them to the 10th-of-the-month close schedule. The bookkeeper does more with SPM oversight than they would do alone.

Usually they stay — repositioned, not replaced. The common SPM structure keeps the in-house person on AP processing, payroll entry, and document flow (the work proximity genuinely helps with) while the outsourced function takes the close, WIP, job costing, and reporting (the work that requires construction accounting depth). The in-house person typically becomes more valuable, not less, because they stop drowning in work they were never trained for. Outright replacement only makes sense when the existing person was already the single point of failure on work they couldn't do.

Properly outsourced accounting gives more visibility than most in-house setups, not less — live dashboards in ControlQore, a close deadline that actually holds, a monthly meeting where the numbers get explained in plain language, and a CEO Report that puts thirteen months of trend on one page. The in-house version's 'control' is often the ability to walk over and ask a question that takes three days to answer. The test isn't where the desk sits. It's whether the owner can see every job's margin and the next thirteen weeks of cash on demand.
