What You'll Need Before You Run Any Numbers

Learning how to value a business for acquisition starts before you open a spreadsheet. You need three years of tax returns, current profit and loss statements, a balance sheet, and a clear picture of what you're buying. Without them, any number is a guess.

Gather these before you begin:

• Federal tax returns for the last three years
• Year-to-date profit and loss statement and balance sheet
• List of tangible assets: equipment, inventory, vehicles, fixtures
• Customer concentration data, meaning what share of revenue comes from your top clients
• Lease agreements, loan documents, and any pending litigation

Three Business Valuation Methods Buyers Actually Use

Every acquisition valuation method falls into one of three families: asset-based, earnings-based, or market-based. Most buyers run two and use the third as a sanity check.

Here's how they compare:

Asset-Based: When the Balance Sheet Is the Whole Story

Asset-based valuation adds up what the business owns and subtracts what it owes: tangible assets at fair market value, receivables at collectible value, minus total liabilities, book value adjusted toward reality.

Earnings-Based: Seller's Discretionary Earnings and EBITDA

Earnings-based valuation asks one question: how much money does this business produce for its owner? Two numbers answer it, and buyers confuse them constantly.

Market-Based: Comparable Company Analysis and Multiples

Market-based valuation prices your target against what similar businesses actually sold for. You look at revenue and earnings multiples from recent transactions in the same industry, then adjust for size, growth, and risk.

SDE vs EBITDA Valuation: Which Number Do You Multiply?

Use SDE when the seller works full-time in the business; use EBITDA when a management team runs day-to-day operations. The number you multiply must match the multiple you apply, because SDE and EBITDA multiples are not interchangeable.

Practical rules for keeping the two straight:

• If the owner's departure would break the business, value on SDE
• If the business runs without the owner, value on EBITDA
• Never mix an SDE number with an EBITDA multiple, or the reverse
• Normalize first: strip out non-recurring expenses and one-time revenue before multiplying

Business Valuation Multiples by Industry

A few mechanics behind those numbers:

• Recurring revenue earns a premium. A SaaS business with 90% gross revenue retention and multi-year contracts prices near the top of its band; the same revenue booked month-to-month prices near the bottom.
• Customer concentration discounts the multiple. When one client exceeds roughly 20% of revenue, most buyers trim the multiple by half a turn or more, because losing that client wipes out the earnings the multiple was applied to.
• Owner dependence caps the multiple. A trades business where the owner still runs jobs and holds the license rarely clears 3x SDE, however clean the books.
• Size matters. Smaller deals carry higher perceived risk, so a $300,000 SDE business often prices below a $3 million EBITDA business in the same sector.

Industry-specific multiples are an important consideration. A multiple fair for a subscription business would be generous for a single-location restaurant, even with identical earnings. Risk drives the multiple, not the earnings line alone.

Step-by-Step: Building Your Valuation in Five Steps

Here's the working process, start to finish. Set aside a full day for the first pass.

Business Acquisition Due Diligence Checklist

• Three years of federal tax returns match the provided financial statements
• Accounts receivable aged, with collectible value confirmed
• Inventory physically counted and valued at current market
• All liabilities disclosed, including equipment leases and pending claims
• Customer contracts reviewed for transferability and termination clauses
• Employee agreements, including non-competes, reviewed
• Tax implications of the deal structure discussed with a CPA
• Working capital requirement defined and funded

Tax implications belong on this list for a reason. Asset and stock purchases are taxed differently, and the allocation of the purchase price across assets changes what both sides owe. Structure decisions made during due diligence can matter more than the headline price.

What Sellers Won't Tell You (and What to Do About It)

Most valuation guides stop at the purchase price. That is where the real work begins. The psychology behind a seller's asking number and the post-acquisition adjustments determine whether the value you paid for shows up on your P&L.

The Psychology of Seller Expectations

Sellers anchor high, and that is rational. What they won't volunteer is where their number came from. Seller asking prices cluster around four anchors, each requiring a different response:

• Emotional attachment. The seller built the business over 20 years and prices it on what it means to them. Response: redirect to comparable transactions and normalized earnings. Emotion does not survive a side-by-side comparison with market data.
• Retirement need. The seller needs a specific number to fund retirement and works backward from it. Response: ask what the number represents. If it is a lifestyle target rather than a market value, you are negotiating against a personal budget, not a business.
• A competing offer. The seller cites another buyer's number. Response: ask for the term sheet. Offers with seller financing, earnouts, or contingent payments are not the same as cash at close, and the headline number rarely reflects the real economics.
• An outdated valuation. The seller had an appraisal done years ago, often in a stronger market. Response: request the report and check the date, the earnings basis, and the multiple applied. Re-run it against current trailing twelve months.

Post-Acquisition Valuation Adjustments

• Working capital true-up. The purchase price usually assumes a normalized level of receivables, inventory, and payables at close. If the seller collects receivables aggressively before closing, you inherit a cash shortfall. Define the working capital peg in the letter of intent and true it up at closing.
• Deferred maintenance and capex catch-up. Sellers underinvest in equipment, software, and facilities in the final year to protect earnings. Build a capex reserve into your model and subtract it from the price, or negotiate a holdback.
• Synergy realization timeline. Cost synergies from combining back-office functions, renegotiating vendor contracts, or consolidating insurance rarely land in month one. Model them over 12 to 24 months and discount them for execution risk. Buyers who pay full value for synergies on day one usually overpay.
