From misreading backlog quality to ignoring license transferability, these errors cost buyers millions in construction deals under $5M revenue.
Find Vetted General Contracting DealsAcquiring a general contracting business offers strong upside in a fragmented market, but project-based revenue, key-man dependency, and hidden liabilities create unique traps. Buyers who skip construction-specific due diligence routinely overpay or inherit serious operational and legal problems post-close.
Buyers often value a company based on its stated backlog without reviewing contract terms, cancellation clauses, or retainage schedules. Unsigned LOIs or verbal commitments get counted as firm revenue.
How to avoid: Review every contract in the backlog. Confirm signed agreements, payment milestones, retainage percentages, and cancellation provisions before accepting any backlog figure at face value.
Many buyers close without confirming whether the general contractor license transfers to new ownership. In many states, the license is tied to a specific qualifier who may leave post-close.
How to avoid: Verify state-specific licensing rules before LOI. Identify whether a licensed qualifier remains post-close or if new ownership requires requalification, bonding reassessment, or a waiting period.
In most sub-$5M GC firms, the owner manages key client relationships, subcontractor coordination, and project oversight personally. Buyers assume this transitions smoothly without a retention plan.
How to avoid: Map every client and subcontractor relationship to a specific person. Require a meaningful transition period and consider earnout structures tied to client and revenue retention post-close.
Sellers often add back owner compensation and personal expenses without supporting job-level profitability data. Thin GC margins make inaccurate EBITDA normalization especially damaging to valuation.
How to avoid: Request three years of job costing reports alongside tax returns and P&Ls. Verify that margins hold at the project level, not just in aggregate, and confirm overhead allocation is accurate.
Buyers overlook whether existing bonding capacity survives an ownership change. A lapse in bonding can disqualify the company from active bids and damage relationships with commercial clients.
How to avoid: Engage the seller's surety early in diligence. Confirm that bonding capacity can be maintained or reestablished under new ownership before closing, and review completed operations tail coverage.
Buyers set working capital pegs without understanding retainage balances and billing-in-excess positions. Post-close cash crunches occur when retainage collection lags and new projects require upfront funding.
How to avoid: Build a detailed working capital model that includes retainage receivables, costs-in-excess balances, and projected cash requirements for projects in progress at the time of close.
Yes. General contracting businesses are SBA-eligible. Lenders typically require 10–15% buyer equity, acceptable EBITDA coverage, and confirmation that the GC license and bonding capacity transfer to new ownership.
Review signed contracts only. Confirm payment schedules, retainage terms, cancellation clauses, and project stage. Discount verbal commitments or unsigned LOIs entirely when building your valuation model.
Tie earnouts to backlog conversion and post-close revenue milestones over 12–24 months. Structure seller notes at 5–10% of purchase price to align incentives during the client and subcontractor transition period.
Most lower middle market GC transactions close between 2.5x and 4.5x EBITDA. Higher multiples apply when backlog is diversified, management is independent of the owner, and licensing transfers cleanly.
