Section 1
The artifact, part one: separate the two values
The single most expensive confusion in a trades sale is treating your standalone value and the platform's value as the same number. They are not. Your standalone value is what your business is worth as one independent shop, and it is the number you can actually negotiate. The platform premium is the extra value your earnings gain the moment they sit on a large platform's balance sheet valued at a higher multiple. That premium is real, but you do not capture it. The platform does, because it is the one doing the consolidating. Chasing the premium in a negotiation just tells the buyer you do not understand which number is yours. So compute the one you own. Work through it in this order. Step 1. Find your true earnings base (SDE). Start with your net profit as the books show it. Then add back the things that are really owner benefit or one-off, because a buyer values the earnings a new owner would keep, not the ones you route through the business for your own reasons. This adjusted figure is your seller's discretionary earnings, or SDE. For larger, management-run businesses the buyer will convert this toward EBITDA by subtracting a market-rate manager salary, but start with SDE because it is the honest picture of what the business throws off today. Step 2. Apply a defensible multiple range, not a single number. Independent trades businesses change hands at a multiple of that earnings base, and for shops under roughly a million dollars in owner earnings that multiple usually sits in the low-to-mid single digits, moving with size, recurring revenue, crew durability, and owner dependence. Do not pick one number. Pick a low end and a high end, because your whole readiness job is moving yourself from the low end toward the high end. Treat any specific multiple as a national talking point that varies by metro, trade, and book quality, not a quote. Step 3. Score yourself on the five value drivers. The position of your business inside its multiple range is set by a handful of factors. Score each honestly, because these are the same factors the buyer scores. Step 4. Compute your range in dollars, and your position in it. Multiply your earnings base by the low and high multiples for your low and high estimate. Then use the five-driver scorecard to place yourself: mostly left-column answers put you near the bottom of the range, mostly right-column answers put you near the top. The gap between your current position and the top of your range, in real dollars, is the prize for getting ready. It is often the largest number in the whole exercise, and it is entirely inside your control.
Section 2
The artifact, part two: the add-back and quality-of-earnings checklist
The reason readiness matters is that a serious buyer does not take your earnings figure on trust. They run a quality-of-earnings review, which is a professional examination of whether your reported profit is real, sustainable, and transferable. Every add-back you claimed in step one gets tested. Add-backs that survive raise your price. Add-backs that get rejected lower it, and worse, a book full of aggressive or sloppy add-backs makes the buyer distrust everything and discount the whole business for risk. So pre-run the review on yourself. Add-backs a buyer will usually accept. These are genuinely owner-specific or non-recurring, and a competent buyer expects to add them back: • Owner's salary and payroll taxes above a market-rate replacement wage • Personal expenses run through the business (owner's vehicle, phone, meals, travel that is not operational) • One-time, non-recurring costs (a lawsuit settlement, a one-off equipment purchase, storm damage) • Discretionary spending a new owner would not continue (charitable giving, an owner's country-club membership) • Above-market rent if you own the building and lease it to the business, normalized to market Add-backs a buyer will challenge or reject. Claim these and you invite the buyer to distrust your whole file: • "One-time" costs that recur every year (they are operating costs, not one-offs) • Deferred maintenance you have skipped, which the buyer will treat as a future cost, not a saving • Family members on payroll who do real work the business will still need • Revenue that depends on you personally and will leave when you do • Anything you cannot document with an invoice or a statement The quality-of-earnings readiness list. Before any call, get these to a state that survives review: • Three years of clean financial statements, ideally accrual-based, with personal and business spending fully separated • A documented add-back schedule with support for every line • A revenue breakdown showing recurring versus one-off, and customer concentration • Proof the business runs without you: an org chart, documented processes, a crew that does not route every decision through you • Tax returns that reconcile to your financial statements, because a gap between the two is the fastest way to lose a buyer's trust Run this list on yourself now, in a quiet quarter, not under an offer. Every item you fix moves you up your own range and shortens the buyer's diligence, which is itself worth money because a clean file closes faster and at a firmer price.
Section 3
Why this is built the way it is: two models, briefly
Mechanism design (the design lens). The buyer's valuation process is a mechanism built to pay you your standalone number while capturing the platform premium, and to use diligence to discount anything you cannot prove. If you walk in with an undocumented earnings figure and a hopeful multiple, the mechanism does exactly what it was designed to do: it anchors low and discounts for risk. The worksheet is a counter-mechanism. By computing your defensible number, documenting every add-back, and pre-running the quality-of-earnings review, you remove the buyer's cheapest tools for marking you down. You are not changing the game. You are refusing to hand the buyer the free moves. Assumes a rational buyer who prices on provable earnings. Breaks with a buyer who is overpaying strategically to win a metro, in which case your readiness matters less and your scarcity matters more. Counteracts the reflex to accept the first anchor. May reinforce over-preparation: at some point the marginal cleanup costs more than the multiple it buys. Comparative statics (the first-order-direction lens). The five-driver scorecard is a comparative-statics tool. Move one driver, hold the rest still, and trace which way your multiple shifts. Add a management layer: owner dependence falls, multiple up. Build a service-agreement book: recurring revenue up, multiple up. The discipline is that it forces you to name the single change that would most move your number, then go do that one thing rather than everything at once. Assumes the drivers are roughly independent, which is a simplification. Breaks at the interactions: reducing owner dependence and building recurring revenue often move together because the same systems drive both. The structure-break flag. This whole worksheet prices today's regime: elevated multiples driven by cheap capital and a mark-to-model consolidation environment where financial buyers account for roughly half of HVAC service transactions (S&P Global Market Intelligence, 2025). That regime can break. If interest rates or platform multiples compress, the premium buyers can pay shrinks, and your defensible standalone number becomes a larger share of any realistic offer. Any number this worksheet produces is a number for the current capital environment. Re-run it if rates move hard, because the multiple you can command is partly a function of how cheaply the buyer can finance the purchase.
Section 4
What the worksheet cannot see
Name the blind spots so you use the number as a floor, not a fact. It cannot price strategic value: a buyer who needs your specific metro, or your specific crew, or a route density that fills a gap in their map may pay well above your computed range, and no worksheet captures that because it lives in the buyer's plan, not your books. It cannot price timing: the same business is worth more in a hot consolidation window than in a cold one, and you do not control the window. And it deliberately simplifies a living business into an earnings figure and five drivers, which means a borderline call belongs with your accountant, not a spreadsheet. The worksheet's job is to make sure you never negotiate blind. It is the starting number, and the buyer's offer is a message about how much strategic and timing value they see on top of it.
Section 5
The fitness test
You are ready to take a buyer's call if you already know your defensible standalone range in dollars, you have placed yourself inside it on the five value drivers, and you have a documented add-back schedule and three years of clean statements that would survive a quality-of-earnings review. Under those conditions an offer is something you measure against a number you trust, and you can push toward the top of your range and toward whatever strategic premium the buyer's own plan justifies, instead of accepting their anchor as the truth. You are not ready, and should not answer on the merits yet, if your earnings figure is a guess, your add-backs are undocumented, or your books commingle personal and business spending, because a buyer will find all three in diligence and price the uncertainty against you. The fix is not complicated, but it takes a quiet quarter: clean the books, document the add-backs, and build enough process that the business visibly runs without you. Do that work before the phone rings, because the owners who know their number negotiate, and the owners who do not, accept.
