Service Business Acquisitions
The central question in buying a service business is not what the business earned. It is what actually transfers when the owner leaves. Service and home-services businesses can show attractive, entirely real historical SDE while a meaningful share of the earnings power lives in the seller personally: the relationships, the estimating judgment, the license, the crew’s loyalty, the reputation attached to a name. The buyer’s work is to decompose the owner’s role into its actual functions, price the ones that must be replaced, and test how much of the revenue is committed to the company rather than to the person walking out the door.
This page is the vertical’s frame, written as practitioner judgment, with the underlying math and rules routed to the articles that work them in depth.
Why is “what transfers?” the central question?
Because in this vertical the income statement and the transferable business can diverge further than in any other common acquisition type, while looking identical on paper. The earnings are real; the seller genuinely collected them. The question is how much of the machine that produced them is the company (crews, contracts, systems, brand) and how much is the seller (relationships, judgment, license, reputation), because the buyer is only buying the first part. A distributor’s inventory transfers by changing a name on a warehouse lease. A plumber’s twenty-year relationships with three property managers transfer only if someone makes them transfer, and sometimes not then. The general diligence framework in the pre-LOI acquisition checklist applies in full; this vertical simply moves owner dependence from one row of the screen to the center of it.
Where does owner dependence actually live?
Framed as practitioner judgment: decompose the owner’s role into functions and test each one separately, because a seller who is replaceable in five of seven functions and irreplaceable in two is a completely different deal from the reverse, and a single “owner dependence: high” label hides exactly that difference.
| Function | The transfer question | What it looks like when it does not transfer |
|---|---|---|
| Sales and relationships | Who do the key accounts believe they hire: the company or the person? Who else has met them? | Revenue follows the seller's retirement, one relationship at a time |
| Estimating and pricing | Can anyone else bid a job at the same margin? Is the pricing logic written anywhere? | Win rates hold but margins erode; or margins hold and win rates collapse |
| Technical or licensed work | Does production capacity depend on the seller's hands or credentials? | A revenue ceiling appears the day the seller stops working |
| Supervision and dispatch | Who assigns crews, sequences jobs, and handles the daily exceptions? | Utilization and callbacks deteriorate before anyone can name why |
| Vendor relationships | Are supplier terms, priority, and pricing attached to the company or to the seller's history? | Cost of goods drifts up; scarce materials arrive last |
| Customer retention and service recovery | Who saves the unhappy account? Whose cell number do customers have? | Churn concentrates in precisely the accounts that mattered |
| Administration and finances | Who invoices, collects, pays, and closes the books? | Working capital quietly deteriorates behind a healthy P&L |
The five seller questions in the checklist are the conversational version of this table; asking them function by function, rather than once in general, is what makes the answers usable.
Owner compensation is not owner replacement cost
SDE is built by adding one owner’s full compensation and benefits back to earnings, so the buyer economically receives what the seller was paid. The error is treating all of that as available cash. Whatever functions from the table above the buyer will not personally perform must be performed by someone, at market cost, and that cost comes back out of the earnings before anything is left for debt service or the buyer’s own income. A business showing strong SDE where the seller sold the work, estimated the work, supervised the work, and kept the books can carry a replacement bill spanning several roles, not one salary. The two numbers deserve two lines in every model: the compensation the SDE convention hands you, and the replacement cost your actual plan requires. How lenders apply exactly this logic inside SBA coverage, and the math of it, is worked in does owner salary reduce SBA debt-service coverage, with the definitional groundwork in what is SDE vs. EBITDA; this page deliberately does not repeat that analysis.
Is the revenue recurring, or merely repeat?
Sort every revenue stream into one of two buckets before pricing anything. Recurring revenue is committed: service contracts, maintenance plans, subscriptions, route work under agreement, anything a customer must act to stop. Repeat revenue is historical: customers who have hired the company again and again but owe it nothing tomorrow. Repeat revenue is genuinely valuable, and it is genuinely different, because its persistence often depends on the same owner relationships the previous sections just put under examination; a repeat customer of the seller is not yet a repeat customer of the buyer. Framed as judgment, the diligence moves are to read the actual agreements behind anything labeled “recurring” (term, cancellation, transferability, pricing escalators), to measure how repeat the repeat business really is from the customer history, and to weight the concentration analysis toward the uncommitted streams. No retention benchmark or valuation premium is offered here because none would survive honest sourcing; the point is the sorting, which any buyer can do from the customer ledger.
What else has to transfer?
The checklist beyond customers, each framed as a diligence question rather than a rule, because the answers vary by trade and by state:
- Licenses and qualifying individuals. Where the trade is licensed, whose credential does the business operate under, and what happens to operations if that person leaves? Whether a license transfers, and whether a qualifying individual must be replaced, are jurisdiction-specific questions for your counsel and the licensing authority; the diligence task is to identify every license the revenue depends on and the named person behind each.
- Key technicians and crews. Tenure, pay against market, certifications held by individuals, and who the customers actually ask for. Retention of the people is retention of the capacity, and it deserves the same attention as retention of the accounts.
- The phone number, domain, reviews, and lead sources. For many service businesses the review profile and the number customers have saved are the brand. Confirm what happens to each in the transaction, how listings and profiles are controlled, and which lead sources are owned versus rented.
- Vendor relationships. Supplier accounts, pricing tiers, and warranty or dealer authorizations: attached to the entity, or to the seller? The asset-versus-stock structure decision interacts with all of these, as covered in asset sale vs. stock sale.
- Operating processes. Whether scheduling, estimating, and job costing live in a system anyone can run or in the seller’s head is the difference between buying a machine and buying a manual that was never written.
This page is practitioner guidance on a vertical, not a statement of licensing rules, which vary by state and trade. Confirm licensing and transfer requirements with your counsel and the relevant authority on the specific transaction.
A representative screen for a service target
Framed as judgment, the order that works: the function-by-function owner decomposition first, because it is cheap and it reshapes everything downstream; then the recurring-versus-repeat sort from the customer ledger, feeding the concentration analysis; then the earnings rebuild with replacement cost on its own line, using the add-back tests and the P&L review; then the transfer checklist above; and for a financed buyer, coverage tested on the post-replacement number, which is where service deals with strong SDE most often surprise, as why profitable businesses fail underwriting shows.
Where NexTax Advisory fits
SDE and EBITDA recasting builds the two-line earnings model (compensation received, replacement cost deducted) this vertical demands; SBA DSCR stress testing runs coverage on the post-replacement number; working capital and peg analysis covers the receivables-and-payables side the administration function hides; and the umbrella engagement is buy-side advisory. Owners of service businesses preparing to sell should see the same picture from the other side in how do I prepare my business to sell: reducing your own role is the slowest fix on the list and the most valuable.
