The Firm That Retires With the Partner
Picture the founding partner most firms his size have. He's the reason the biggest clients signed, he's the last set of eyes on the returns that carry real risk, and he's the person the staff walk down the hall to ask when something doesn't sit right. He built something good. He also built something that ends the week he stops coming in, and he has not fully admitted that to himself.
This is the most common shape of a lower middle market accounting firm, and the clock on it is louder than the profession likes to say. Roughly three in four CPAs plan to retire within 15 years, and depending on which survey you read, only about 41 percent of firms have a formal succession plan in place. The average managing partner is already 55. Back in 2020, more than half of licensed CPAs in the country were over that same age. The retirements are not a distant risk. They're scheduled, and the plan to absorb them is mostly missing.
Two dependencies, one exit
Partner dependence in a firm is really two problems wearing the same coat, and they fail differently.
The first is relationship dependence. The clients belong to the partner, not the firm. They pick up the phone because it's him, they'd follow him if he left, and they'd wonder whether to stay if he retired. The second is technical dependence, which is quieter and often worse. The final review runs through one person's judgment. He's the one who knows why this client's inventory reserve always looks strange, or which owner takes distributions that need a second look. That knowledge was never written down. It lives behind his eyes, and it walks out with him.
A firm can limp along with one of these. With both, the firm is really a founder with some staff attached rather than a business with a founder, and the two are worth very different amounts to anyone who might buy it.
The market is sorting firms on exactly this
That last point stopped being theoretical. Accounting M&A set a record in 2025, with transaction volume up more than 25 percent, and the private equity money behind it has been unmistakable. Industry bodies have counted over 1000 firms touched by PE investment across the past decade, and the roll-up strategy specifically targets smaller firms. Whatever you think of that trend, it has created a live and well-capitalized market for accounting firms of your size.
Here's what that market pays for, and what it discounts. A buyer is buying transferable relationships and a review function that survives the founder. When the clients belong to a team and the technical judgment sits in documented processes and trained managers, the firm carries a real multiple of revenue. When both live in one retiring partner, the buyer prices in the risk that the clients leave and the quality slips the moment he's gone, and the offer reflects it. The same firm is worth substantially more or less depending entirely on how deep the founder dependence runs. Succession isn't only about who takes over. It's about what the thing is worth on the way out.
Build the successor before you need one
The org chart is rarely what makes succession fail. It fails because no successor was ever developed, since the institutional knowledge and the client trust stayed in the retiring partner's head where they were easiest to keep.
Undoing that is slow work, which is why starting late is the whole danger. Move relationships deliberately, so the second name on every major account is a manager the client already trusts, not a stranger introduced at the handoff. Pull the review knowledge out of one person's judgment and into checklists, workpaper standards, and a second reviewer who's being trained to see what the founder sees. Neither happens in a year, and neither happens under deadline pressure, which is exactly why the firm that waits for the retirement to force the issue has already lost most of its options.
If you're the founder, stop asking when you want to retire. Ask whether the firm can run a full busy season without you in the building. If the honest answer is no, that's not a plan you have 5 years to write. That's the work in front of you now, and every year you carry it in your head is a year the firm quietly agrees to retire when you do.
