Buying a Bookkeeping Practice Where One Employee Was the Business

The situation

Priya had spent more than a decade as an air traffic controller after moving to Canada, a job that paid well and demanded total precision but left her wanting something she could build and eventually hand to her own children. When a small accounting and bookkeeping practice in Oshawa came up for sale, she saw an opening. The practice, run for close to twenty years by its owner, Selam, served roughly ninety small businesses and self-employed clients across the area, handling monthly bookkeeping, payroll and year-end tax filings. Selam was ready to retire and had priced the practice at close to $2,950,000, reflecting its steady recurring revenue and long client history.

Priya came to us with a signed letter of intent and financing largely arranged, wanting the purchase agreement drafted quickly so she could close before the practice's busy tax season. On paper, the deal looked straightforward: a well-run business, a motivated seller, and a buyer with the cash and the accounting background from years of managing her own household finances and a small side bookkeeping course she had completed after immigrating. What the letter of intent did not address was who, exactly, Priya was buying along with the client list.

What due diligence found

An accounting practice's real asset is not its filing cabinets or its software licence. It is the trust clients place in the specific person who has done their books for years, and in this practice, that trust sat overwhelmingly with one employee: Biniam, the practice's senior accountant, who had worked alongside Selam for eleven years and personally handled close to sixty percent of the client base. Selam remained the owner and the face of the practice, but Biniam did the work, took the calls, and knew which clients were late payers, which ones needed hand-holding at tax time, and which ones would leave the moment service felt unfamiliar.

When our team reviewed the client files and staffing during due diligence, the concentration was hard to miss, and so was a second problem: nobody had asked Biniam what he wanted. Selam assumed he would simply stay on under new ownership, the way he always had. Biniam had not been consulted, had no written retention arrangement, and — as it turned out when we raised the question directly — was already fielding an informal offer from a larger firm in the area.

The structure of the deal made this more urgent, not less. Priya and Selam had agreed to an asset purchase, where Priya's new corporation would buy the practice's client list, equipment and goodwill directly, rather than buying shares in Selam's existing company. In an asset sale, employees do not automatically transfer with the business. Legally, Selam's employees remain Selam's employees until someone — Priya — extends them a new offer of employment, and they accept it. If Biniam declined and left for the competing firm, a meaningful share of the roughly $2,950,000 in goodwill Priya was about to pay for would likely leave with him within a matter of months.

What we did

1. Quantified how much of the purchase price rode on one relationship. Working from the client list and billing history, we mapped which clients Biniam handled directly and estimated that his departure could put roughly $500,000 to $600,000 of the practice's annual revenue at meaningful risk within the first year — not because those clients disliked the business, but because many of them had never dealt with anyone else there.
2. Raised the issue with Selam before the purchase agreement was finalized, not after. Sellers are often reluctant to have this conversation, because it can feel like it undermines the value of what they are selling. We treated it as a shared problem instead: if Biniam left before or shortly after closing, it would hurt Selam's ability to close the deal at all, giving both sides reason to solve it together rather than leave it for Priya to discover after the fact.
3. Structured a formal, written offer of employment for Biniam, conditional on closing. We drafted an offer confirming his role, compensation and reporting line under the new ownership, and made the deal's closing conditional on him accepting it. We also built in continuity language recognizing his eleven years of service with Selam's business for purposes of future entitlements, consistent with how the Employment Standards Act, 2000 treats an employee's length of service when a business is sold and the employee is kept on without an interruption in employment.
4. Negotiated a retention bonus tied to Biniam staying, split between buyer and seller. Rather than leaving Biniam's loyalty to goodwill alone, we negotiated a retention bonus of roughly $90,000, paid in instalments over eighteen months, with the cost shared between Selam — who reduced his purchase price to help fund it — and Priya, who agreed to carry the ongoing portion after closing.
5. Used a non-solicitation clause rather than a non-compete. Ontario employment law restricts non-compete clauses for employees in most circumstances, so instead of trying to stop Biniam from ever working elsewhere in the industry, we focused on a narrower, more defensible non-solicitation clause preventing him from actively soliciting the practice's clients if he ever did leave — a term with a real chance of being enforced if it were ever tested.
6. Tied part of the purchase price to client retention after closing. Because no retention bonus can force an employee to stay, we negotiated a holdback of $150,000 of the purchase price, payable to Selam six months after closing only if client attrition in Biniam's book of business stayed under an agreed threshold — giving Selam a direct stake in a smooth handover rather than treating his job as finished at the signing table.

The outcome

Biniam did not sign immediately. Once he understood he had leverage, he countered for a larger guaranteed upfront payment rather than an eighteen-month schedule, reasoning that a new owner's promises were worth less than cash in hand. The parties settled on a compromise: roughly $35,000 of the $90,000 retention bonus paid at closing, non-refundable, with the remaining $55,000 vesting over the following twelve months instead of eighteen. In exchange, Selam agreed to reduce the purchase price by a further $65,000, on top of the amount already redirected to fund the bonus, bringing the final price to about $2,835,000. Neither side got everything they wanted — Priya paid out more cash at closing than she had planned, and Selam walked away with less than his original asking price — but both sides closed with terms they could live with, and closing went ahead on schedule before tax season began.

Biniam stayed. In the first eight months after closing, the practice lost a small number of clients to normal attrition — retirements, business closures and a couple of departures unrelated to the sale — amounting to roughly $65,000 in annual revenue, well under the threshold that would have triggered the holdback reduction. Selam received his full holdback payment six months after closing. Priya spent her first year learning the practice's client relationships directly alongside Biniam, gradually building her own rapport with the clients he had carried, so that the practice's dependence on any one person would matter less by the time his retention bonus fully vested.
