A DFW Owner’s Guide: How to Value Your Service or Construction Business

A service, professional services, or construction business is valued by applying a multiple to its normalized earnings. Earnings are measured as either SDE (Seller’s Discretionary Earnings) for owner-operated firms or EBITDA for larger, management-run firms. The multiple, usually somewhere between 2x and 7x, is set by how dependable and transferable those earnings are. Two shops with identical revenue can sell for wildly different prices, and the gap is almost never about revenue. It’s about risk.

That’s the whole model. Everything below is the detail that decides where your number lands inside it.

The formula every buyer starts with

There’s no magic to the starting math. A buyer takes your earnings and multiplies them:

Normalized Earnings × Multiple = Enterprise Value

A roofing company in Fort Worth doing $400,000 in normalized SDE at a 3x multiple is a $1.2M business. The same $400,000 at a 4x multiple is a $1.6M business. That one turn of the multiple, a $400,000 swing, is what we spend most of our time helping owners earn before they ever talk to a buyer.

How do I value a service business quickly?

Take your normalized earnings, multiply by a market multiple, roughly 2x–4x SDE for an owner-operated business, 4x–7x EBITDA for a larger one, and you have a working number in minutes. That’s the back-of-the-napkin version. The three steps below are what make that number defensible when a real buyer pressure-tests it: what counts as earnings, which metric applies, and what makes a buyer pay 4x instead of 3x.

Step 1: Normalize your earnings (this is where money hides)

The number on your tax return is not the number a buyer values. Business owners run personal and discretionary costs through the company, and they manage the books to minimize taxes, which means the reported profit understates the real earning power of the business. Normalizing (also called “recasting”) strips that noise out so a buyer can see what they’d actually take home.

Common add-backs that legitimately increase your earnings number:

• Owner’s salary and payroll taxes above a market-rate replacement
• One-time or non-recurring expenses (a legal settlement, a single big equipment repair)
• Personal expenses run through the business (vehicles, phones, travel, memberships)
• Owner’s health insurance and retirement contributions
• Rent paid to yourself above or below market, normalized to market

Done right, recasting can move reported profit up substantially. Done sloppily, or aggressively, it backfires. Buyers and their accountants scrutinize add-backs in diligence, and a stack of unsupported ones reads as a red flag that makes them trust every number less. The goal is defensible, not maximal.

If you can’t document an add-back with a clean paper trail, it isn’t an add-back. It’s a story, and buyers don’t pay for stories.

Step 2: Use the right earnings metric, SDE or EBITDA

Which earnings number you start from depends on the size and structure of your business:

• SDE is used for smaller, owner-operated businesses, the kind where the owner is in the field, on the phones, or signing every check. It adds the owner’s full compensation back in, because a buyer is stepping into that role.
• EBITDA is used for larger businesses run by a management team without the owner in the daily work. It treats the owner’s pay as a normal expense, because the next owner won’t be doing that job.

Picking the wrong one will distort your value by a wide margin. This distinction matters enough that we wrote a separate, plain-English breakdown: EBITDA vs. SDE: which number actually values your business.

Step 3: Earn the multiple

This is the part most owners get wrong. They obsess over revenue and earnings, then act surprised when the multiple comes in low. But the multiple is the scoreboard for one thing: how much of the business walks out the door when you do.

A buyer paying 4x instead of 3x is paying for confidence, confidence that the revenue shows up next year, that the team stays, that the customers don’t leave, and that they aren’t buying a job they now have to work themselves.

Does more revenue mean a higher valuation?

Not necessarily. Revenue raises the earnings base, but the multiple is set by risk, not size. A smaller, lower-risk business routinely sells for a higher multiple, and sometimes a higher total price, than a larger business that depends entirely on its owner. Chasing top-line growth while ignoring the risk factors below is how owners end up with a bigger company that’s worth less than they expected.

The five levers that move your multiple

After years of operating and preparing businesses for sale, the same five levers decide the multiple almost every time. We call it the value engine, and it works whether you pour concrete or file tax returns:

1. Recurring revenue. Maintenance contracts, retainers, service agreements, and repeat clients are worth far more than one-off project work, because they’re predictable. A buyer pays up for revenue they can count on.
2. Owner independence. If the business can’t run a full quarter without you, you don’t own a business, you own a high-paying job, and buyers discount jobs heavily. The more the company runs on systems and a team instead of on you, the higher the multiple.
3. Clean financials. Accrual-based books, reconciled monthly, with a clear separation between business and personal. Messy financials don’t just lower the multiple, they extend diligence, kill momentum, and sink deals.
4. Customer diversification. If one client is 40% of revenue, a buyer prices in the risk of losing them. No single customer concentration above ~10–15% is a far easier story to sell.
5. Margin quality. Healthy, stable, defensible margins signal pricing power and operational discipline. Margins that swing wildly, or that only hold because the owner works for free, get discounted.

A business can move a full turn or more on the multiple by improving these, without adding a dollar of revenue. That’s the entire premise of working on value before you sell.

A worked example (so the numbers feel real)

What multiple do construction and trades businesses sell for?

Most small, owner-operated trades businesses trade in the 2x–4x SDE range. Larger contractors with management teams, recurring service revenue, and clean financials can reach EBITDA multiples of 4x–6x or more. The single biggest factor pulling that number down is owner-dependence, followed closely by customer concentration. Here’s what that looks like in practice:

Construction / trades. An electrical contractor in Arlington reports $250,000 in profit. After normalizing, adding back the owner’s above-market $120,000 salary, a personal truck, and a one-time bad-debt write-off, true SDE is $410,000. The owner is the top estimator and holds every key client relationship personally. Two clients make up half of revenue. That concentration and owner-dependence pulls the multiple to ~2.75x. Value: roughly $1.13M.

Now imagine that same owner spends 18 months building an estimating bench, moving clients onto annual service agreements, and broadening the customer base. SDE holds at $410,000, but the risk profile transforms. The multiple moves to ~4x. Value: roughly $1.64M, a half-million-dollar gain from de-risking, not from selling more.

Professional services. A DFW accounting practice with $900,000 in recurring annual retainers, clean books, and a team that runs client work without the founder will command a stronger multiple than a same-size practice where the founder personally services the top 20 accounts. Same revenue. Different business. Different price.

Why DFW context matters

Dallas-Fort Worth is one of the most active markets in the country for buying lower-middle-market businesses, strong population growth, heavy in-migration of capital, and a deep bench of buyers ranging from local operators to regional consolidators and private equity-backed platforms rolling up trades and service firms. That demand is good news for sellers, but it also means buyers here are experienced. They’ve seen hundreds of these deals. A business that isn’t prepared gets priced like one.

What a valuation like this is not

This is a market-based estimate of what a buyer would likely pay, the same lens a real buyer uses. It is not a formal, certified appraisal for legal, tax, divorce, or estate purposes. If you need a defensible number for the IRS or a courtroom, you need a credentialed valuation professional. For understanding what your business is worth in a sale, and, more importantly, what’s holding the number down, the earnings-times-multiple approach above is exactly how the market thinks.

How far in advance should I prepare to sell?

Ideally 12–24 months out, not the week you decide to sell. You can’t control the multiple buyers are willing to pay in general, but you can control how much of it your specific business earns, and the five levers take time to move. The gains compound: owners who start de-risking a year or two early routinely capture six-figure increases in enterprise value that owners who rush to market simply cannot. The number isn’t fixed. It’s a function of the business you hand over, so build the business worth more before you need to.
