How should I prepare my construction business for a sale?

By Michael D. Rubin, CEO & Founder · September 2026 · 827 words

Prepare a construction business for sale by making its numbers trustworthy job by job, moving customer and estimating relationships off the owner, documenting backlog and licensing, and growing the share of revenue that repeats. Start 12 to 24 months before you want to sell. One note on scope: MDR & Associates represents trade and home-services companies such as HVAC, plumbing, roofing, landscaping, garage door and pest control businesses, not general contractors or project-bid construction firms. The preparation below applies to both.

Make the financial records match how contractors are judged

Buyers of contractors look past the annual profit figure to whether profit is real on each job. That requires:

• Job costing that assigns labor, materials, equipment and subcontractor costs to the job that incurred them.
• A reliable work-in-progress (WIP) schedule showing, for each open job, the contract value, costs to date, billings and estimated profit.
• Consistent revenue recognition, usually percentage-of-completion for longer jobs, agreed with your CPA and applied the same way every year.
• Three years of statements that reconcile with tax returns, plus current monthly financials.

Watch the billing gap buyers study most

Overbillings and underbillings, the gap between what you have billed and what you have actually earned on open jobs, get close attention. Large or sudden swings prompt questions about whether profit was pulled forward or whether problem jobs are being hidden. Review the WIP schedule with your CPA every month for the year before a sale, so the numbers a buyer sees have a clean, consistent history.

If your books are kept on a cash basis, or job costs are lumped into general expense accounts, fixing that is the first project. Buyers and their lenders want a year or two of accrual-based, job-costed statements before they will trust the WIP schedule, and that history cannot be created after the fact.

Separate the company from the owner

In many contracting companies the owner is the estimator, the relationship with builders and property managers, the license holder, and the personal guarantor to the bank and the surety. Each of these is a reason for a buyer to lower the price or walk away. Train or hire an estimator, introduce project managers to key customers, and put a second licensed person in place if the company's license depends on you as the qualifier.

Personal guarantees matter just as much. If you have guaranteed the company's credit line, equipment loans or bonding, a buyer will have to replace those guarantees at closing. Start the conversation with your bank and surety early, so their requirements do not delay the sale.

Document backlog and customer relationships

Keep a clean backlog report: signed contracts not yet performed, with expected margin and timing. Buyers will compare it with the same point in prior years, so keep past year-end backlog reports too. List your repeat customers and how long each has worked with you. If one builder, developer or general contractor accounts for a large share of revenue, work on spreading that out before going to market, because buyers price dependence as risk.

Clean up the operating side a buyer will inspect

Buyers go through operations just as closely as the numbers. Anything missing or expired becomes a due diligence question, and too many questions slow a deal or lower the price. Have these ready and current:

• Equipment and vehicle list with condition, titles and any loans
• Safety program, incident history and insurance loss runs
• Warranty and callback records
• Licenses, permits and insurance certificates
• Employee roster, key technician and crew leader roles, and any retention risk
• Subcontractor agreements and lien waivers

Grow the revenue that repeats

Service agreements, maintenance contracts and repeat residential or commercial customers are worth more to buyers than one-off bid work. For a trade contractor, that might mean offering maintenance plans to customers whose equipment you installed, or dedicating a crew to service calls. Growing that side even modestly before a sale, and reporting it separately, gives buyers a reason to pay more and widens the range of buyers who are interested. Our general guide to preparing a business for sale covers the rest of the list.

Be realistic about timing. A service department started six months before a sale shows intent but little history. One that has grown steadily for two or three years shows a buyer a trend it can pay for.

How MDR & Associates helps

For trade and home-services companies, MDR & Associates offers pre-exit consulting in the 12 to 24 months before a sale, then takes the company to market through the ten-step process. See what we look for on our home services page. If you own a general contractor, the checklist above still applies, and we will tell you honestly that it is outside what we represent. Owners who start early often find the preparation raises value on its own, whether or not they sell on the original schedule.
