Taking over a retiring operator’s client list with an earn-out (example scenario)
An illustrative pathway, not a listing: buy the client list or "book of business" of a solo operator who is retiring (for example a bookkeeper, lawn care operator or cleaner), paying a small amount up front and the rest as an earn-out tied to the revenue you actually keep. Earn-outs are negotiated deal by deal and are never guaranteed to be offered.
Example scenario. This shows how the costs and steps of this path typically fit together. It is not a business for sale, and nothing here means financing is available to you.
Cash to start (upfront + working capital)
$2,000–$5,000 + unverified items
Ongoing costs per month
Not verified
plus debt payments
Time
Part-time possible, ~20+ hrs/week
What it costs to start
Amounts are itemized estimates. “Not verified” means we don’t have a defensible figure; it is not $0.
| Item | Type | Estimate |
|---|---|---|
| Insurance and business registration Varies by trade and state. Many clients expect liability insurance from day one. | Initial setup | Not verified |
| Up-front payment to the seller Example arithmetic only: assumes a $20,000 total price with 10% to 25% paid at signing ($2,000 to $5,000) and the rest paid as an earn-out. Some deals have no up-front payment; others are all cash. The split is whatever you and the seller agree. | Down payment | $2,000–$5,000 |
| Equipment, tools or software to serve the clients Depends on the trade. Some sellers include their equipment; check what is and is not part of the deal. | Equipment | Not verified |
| Attorney review of the purchase and earn-out agreement Depends on the attorney and how complex the terms are. The agreement should define "retained revenue", the payment period, reporting and what happens if clients leave. | Deposits and transaction costs | Not verified |
| Upfront costs (required) | $2,000–$5,000 + unverified items | |
| Working capital | Not verified |
Ongoing costs
| Item | Per month |
|---|---|
| Earn-out payments to the sellerDebt service Usually a negotiated percentage of revenue from the transferred clients for a set period, so it rises and falls with what you keep. Model it at several retention levels. | Not verified |
| Normal operating costs (supplies, software, fuel, insurance) | Not verified |
Financing
An earn-out works like seller financing: the seller is paid from future revenue instead of cash at closing. It is negotiated case by case and many sellers prefer cash. Earn-out terms are a frequent source of disputes, so define how revenue is measured and reported.
What you need
- Tools or software needed for the trade
- Client records transferred with proper consent
- Helpful: Skills and any license the clients’ work requires — Some books of business, such as tax preparation, insurance or financial advice, can only be served by a licensed or credentialed person. Many trades need none.
- Helpful: Seller cooperation during the handover — Introductions from the seller strongly affect how many clients stay. Put the seller’s transition duties in writing.
Licensing: Depends entirely on the trade. A general business registration is common. Regulated fields (tax, insurance, financial services, some trades) have their own licensing and client-consent rules for transferring files.
Skills that help: Customer service, Operations and management, Sales.
Time: Hours depend on how many clients come over. A small book might be served part-time; a full book usually replaces a full-time job.
Typical customer: The retiring operator’s existing clients, if they agree to stay with you
How it makes money: You serve the clients at their existing or renegotiated rates and pay the seller an agreed share of retained revenue for a set period
Business model: Existing business acquisition, Partnership, Local service business
Risks and downsides
- Clients may leave once the person they trusted retires, even with a warm introduction.
- Vague earn-out definitions ("retained revenue", "clients transferred") lead to disputes with the seller.
- The seller may have been undercharging, and raising prices can trigger more departures.
- Client contracts or data may not be legally transferable without consent.
- Concentration risk: a few large clients may make up most of the revenue.
- You may owe earn-out payments on revenue you have already spent on taxes and costs.
Your first step
Ask two operators in a trade you know whether they plan to retire within five years and what they would want for their client list; write down what records they could actually show you.
Then
- Ask the seller for a client list with revenue per client for the last two years, then verify it against deposits.
- Sketch earn-out payments at 50%, 75% and 90% client retention to see what you would actually owe and earn.
- Have an attorney draft or review the agreement, including a non-compete and the seller’s transition duties.
- Plan the introduction letter or visit the seller will make to each client.
