Small Business Valuation: How to Value Your Business Before You Sell
Most trade business owners don't actually know what their company is worth. They either lowball themselves out of years of built-up value, or they walk into a sale expecting a number no buyer will pay.
We've built this guide from real experience — performing valuations, making offers, and buying multiple small businesses ourselves at TradeBrain. Here's exactly how small business valuation works for trade and service businesses, and what actually moves your number.
What Is Small Business Valuation?
Small business valuation is the process of estimating what your company would sell for in the current market. It's not your revenue, and it's not a number you pick because you need it to fund retirement.
For trade businesses specifically, buyers are almost always looking at:
- Adjusted net profit — also called Seller's Discretionary Earnings (SDE)
- Customer concentration — how much revenue depends on one or two clients
- Recurring work — contracts and repeat customers versus one-off jobs
- Documented systems — can someone else run this from your SOPs, or does it live in your head
- Owner dependence — does the business run without you in it
The Three Ways to Value a Trade Business
There's no single formula, but almost every valuation you'll see boils down to one of these three methods.
| Method | How It Works | Typical Multiple |
|---|---|---|
| Net Profit Method | Average net profit (last 2–3 years) × multiple | 3–4× |
| Revenue Multiple | Annual revenue × multiple | 0.3–0.5× |
| Seller's Discretionary Earnings (SDE) | (Profit + owner's wage) × multiple | 2–3× |
1. Net Profit Method
Take your average net profit over the last 2–3 years and multiply by 3–4×. Example: $20,000 average net profit × 3 = $60,000 valuation.
2. Revenue Multiple
Service businesses often sell for 0.3–0.5× annual revenue, higher if they're well-run and profitable. Example: $180,000 revenue × 0.4 = $72,000 valuation.
3. Seller's Discretionary Earnings (SDE)
Some sellers add their own wages back into profit before applying a multiple. This only works if your labour is easily replaceable — if you're still swinging a hammer every day, a buyer has to hire someone to do that, which lowers what they'll pay.
What Trade Businesses Actually Sell For
Ranges vary a lot by trade, but as a rough benchmark: owner-operator trade businesses (plumbing, electrical, HVAC, landscaping) with $150K–$500K in SDE typically sell in the 2–3× SDE range in Canada. Businesses with recurring contracts, a management layer, and documented systems push toward the higher end — or beyond it. A business that's 100% dependent on the owner, with no team and no systems, often sells closer to 1–2×, because the buyer is really just buying a job.
Step 1: Understand How Your Business Actually Runs
Before the numbers, be honest about the mechanics:
- What services do you offer, and which ones are actually profitable?
- Are your clients recurring, or mostly one-time jobs?
- Who does the work — you, employees, or subcontractors?
- How involved are you in day-to-day operations?
A business that only runs because you're in it every day is worth less — unless you're willing to stay on through a transition, or you've already hired someone who could replace you.
Step 2: Clean Up Your Financials
You can't get an accurate valuation on messy books. Before you go further:
- Separate your wages (what you earn doing the work) from business profit
- Strip personal expenses out of the books
- Track contractor and subcontractor costs clearly
- Make sure your P&Ls and tax returns actually match your bank statements
- Pull together 2–3 years of clean records for review
Clean books don't just make the valuation easier — they directly increase the number a buyer is willing to pay, because they remove risk.
Step 3: Know Your Real Profit — Not Just Revenue
Revenue is what clients pay you. Profit is what's left after wages, materials, insurance, fuel, and everything else.
- Revenue = total sales
- COGS = wages, materials, contractor fees
- Operating expenses = admin, software, rent, phones
- Net profit = what's actually left over
Your own wages need to be pulled out of profit separately — especially if you're still doing billable work yourself.
Step 4: Are You Selling a Job or a Business?
This is the single biggest lever on your valuation. If the business only functions because you're working in it full-time, you're not selling a business — you're selling a job with some clients attached, and buyers will price it that way.
To increase your value before you list:
- Document your systems and SOPs so someone else can run the work
- Delegate day-to-day jobs to your team, not yourself
- Spend 6–12 months proving the business runs without you in every job
Step 5: Look at the Full Picture — Growth, Risk, and Team
Buyers (and you) should weigh more than the trailing numbers:
- Can the business grow, or has it plateaued?
- Is there room to raise prices without losing clients?
- Would the team stick around through a change of ownership?
- Is the client base loyal and diversified, or concentrated in one or two accounts?
A business with average numbers but a strong team and loyal client base can be worth significantly more than the raw math suggests — and the reverse is also true.
Step 6: When Not to Sell (or Value)
Sometimes the right move is to wait. Hold off if:
- Last year was a fluke — unusually good or unusually bad
- Your books aren't clean yet
- Most of your revenue still comes directly from your own labour
- You're mid-transition — new pricing, team turnover, a system change
Give it 6–12 months to stabilize and grow the number instead of valuing (or selling) at a low point.
Step 7: Protect the Deal With the Right Terms
If you do sell, structure it properly:
- A non-compete clause, so you can't open the same business next door
- A clear list of what's included — equipment, website, phone number, software logins
- A defined transition period to train the new owner
- A retention bonus for key staff to stay through the handoff
- Clear terms on client retention
- Full disclosure of any debts or outstanding tax issues
Step 8: Prepare Your Clients for the Transition
Optional, but it protects the value you just sold. Be ready to introduce the new owner personally, reassure clients the service won't change, and make it obvious you trust the person taking over. A smooth handoff protects the retention numbers the buyer paid for.
Frequently Asked Questions
How much is my small business worth?
Most owner-operator trade businesses in Canada sell for 2–3× their Seller's Discretionary Earnings (SDE), though it ranges from roughly 1× for a highly owner-dependent operation up to 4× or more for a business with recurring contracts, a management layer, and documented systems. The fastest way to get a real number is to average your last 2–3 years of adjusted profit and apply a multiple based on how dependent the business is on you personally.
What is small company valuation based on?
Small company valuation is based primarily on adjusted profit (SDE), not revenue. Buyers also weigh customer concentration, how much recurring or contracted work exists, whether processes are documented, and how dependent the business is on the current owner. Two companies with identical revenue can have very different valuations based on these factors alone.
How do I increase my business's value before selling?
Clean up your financials so profit is clearly documented, remove yourself from day-to-day delivery by building out your team and SOPs, diversify your client base so no single account is a risk, and lock in recurring contracts where possible. Most of these changes take 6–12 months to show up meaningfully in your numbers.
Should I use revenue or profit to value my business?
Profit — specifically Seller's Discretionary Earnings (SDE) — is the standard for small and mid-sized trade businesses, not revenue. A revenue multiple is sometimes used as a sanity check, but two businesses with the same revenue and very different profit margins are worth very different amounts. Buyers are purchasing your cash flow, not your top line.
Do I need a professional valuation, or can I estimate it myself?
You can get a solid working estimate yourself using the methods in this guide, and it's worth doing before you talk to anyone. For an actual sale, a professional valuation (or a broker's opinion of value) adds credibility buyers and lenders will want to see — but knowing your own number first means you won't be negotiating blind.
