Why Organic Growth Is Losing to Roll-Ups and How Firms Under $2M Can Still Win

Private equity closed 183 accounting firm deals in 2025, nearly four times the 2023 total, and each direct PE deal now sets off roughly seven follow-on roll-ups in that market. If you’re trying to grow an accounting firm below the $2M mark, you’re not the target here, and that’s actually good news. Roll-ups chase scale and recurring EBITDA. Smaller firms win with a niche, a real referral system, and faster follow-up than the newly merged competitor down the street can manage.

Three years ago, nobody outside the industry paid much attention to who was buying accounting firms. That’s changed fast. PE-backed buyers signed off on 183 deals in 2025 alone. Back in 2023 it was 47. More than a third of the top 30 firms in the country by revenue have already sold a stake to a private equity investor, and the pattern isn’t slowing down. 

Here’s the part that surprises most owners: between 2015 and 2025, 177 direct PE investments led to 875 follow-on acquisitions. One deal in a region almost guarantees seven or eight more will follow as that platform hunts for bolt-on firms. If you’re running a $1.2M practice and just watched a competitor get bought, it’s natural to assume the writing’s on the wall for anyone who isn’t part of that wave. 

We don’t think that’s true, and we’ve watched enough of these markets play out to say so with some confidence. Roll-ups are built for a specific size and shape of firm. If you’re not there yet, or don’t want to be. There’s still a very real answer to how to grow an accounting firm on your own terms. It just requires doing a few things on purpose instead of hoping referrals show up. It just requires doing a few things on purpose instead of hoping referrals show up.

Why are private equity firms buying accounting practices right now?

Because accounting checks two boxes PE loves: money that keeps coming back (retainers, recurring compliance work, advisory contracts) and a market so fragmented that no single firm owns more than a rounding error of it. Buy one firm, use it as a base, and start absorbing smaller ones nearby.

IFAC found that fewer than 200 direct PE investments produced about 900 total transactions in 2025 once you count the roll-ups that followed. The firms getting bought aren’t random. 

Firms that are mostly compliance and tax prep, thin margins, seasonal revenue, don’t attract the same interest. That’s not a knock on those firms. It just means the pressure they feel from consolidation looks different than what a $5M advisory-heavy firm experiences.

How does a roll-up hurt a firm that isn’t even being acquired?

It doesn’t take your clients directly. It changes the ground you’re competing on. Three things tend to shift once a well-funded platform shows up in your market:

• Recruiting gets harder. A PE-backed firm can usually out-pay you for junior staff, at least for a while.
• Marketing gets louder. More budget means more visibility, even if the work underneath isn’t actually better.
• Referral sources get pulled at. Attorneys and bankers who used to send you work start getting courted by someone bigger.

None of that is fatal. It just means the old approach- do solid work, wait for the phone to ring- gets slower and less reliable when there’s a better-funded competitor actively hunting the same clients you are.

Can a firm under $2 million actually grow without private equity behind it?

Yes. And there’s a real advantage smaller firms have that gets underrated: clients notice when a firm they trusted gets folded into something bigger. Pricing shifts. Their usual contact turns over. The partner who used to answer the phone now has three other offices to manage. That friction sends clients looking elsewhere, and a firm with an active growth engine is in position to catch them.

We built our Sales & Marketing Academy around exactly this problem. Most owner-operators never got taught how to sell. They got taught how to do the technical work well and figured client acquisition would sort itself out. It doesn’t, not at the pace needed to grow an accounting firm while a roll-up is active in the same market.

How to Grow an Accounting Firm Without Private Equity

It’s less exciting than it sounds. Firms that grow steadily without PE money tend to do the same handful of things, consistently, instead of a big splashy campaign once a year:

1. Pick one or two niches and get known for them (dental practices, construction, medical groups, whatever fits your background).
2. Build a real cadence for reaching out to referral sources, not just a holiday card once a year.
3. Answer new leads within hours, not days.
4. Track where clients come from so you know what’s working.

That last one trips up more firms than you’d expect. A lot of owners can’t tell you whether last quarter’s growth came from referrals, a website form, or a partner’s LinkedIn post. If you don’t know, you can’t do more of what’s working.

Does specializing in a niche actually help against bigger, PE-backed firms?

It’s probably the single best lever a small firm has. A firm known as “the CPA for dental practices” in a metro area can charge more, gets referred by name, and isn’t fighting on price against a competitor with a bigger ad budget. A generalist platform covering five industries across three states is never going to out-niche you on dental practice overhead ratios or construction percentage-of-completion accounting. That depth is yours to own if you commit to it.

Is this actually a bad time to try to grow, given how much consolidation is happening?

We’d argue the opposite. Every roll-up transaction creates displaced or unhappy clients somewhere, and those clients have to land with somebody. Firms actively building a growth engine are the ones who catch that overflow. Firms sitting back, waiting for the phone to ring, mostly aren’t.

That window narrows over time. Markets that look fragmented today won’t stay that way once a platform has finished its local buying spree. The firms that start building real acquisition systems now, while things are still moving, end up in a much stronger spot than the ones who wait until the pressure is impossible to ignore.

FAQs

How can a small accounting firm grow without private equity backing?

By building a real client acquisition system, a defined niche, consistent referral outreach, and fast follow-up on leads, instead of relying on word of mouth alone. This lets a firm grow an accounting firm steadily even next to better-funded, PE-backed competitors.

What size accounting firm typically gets acquired by private equity roll-ups?

Most targets are above $2 million in revenue with a strong recurring advisory mix. Firms below that threshold usually aren’t on a roll-up’s radar, which is exactly why organic growth stays the primary path for them.

Do clients actually stay loyal after their firm gets bought by private equity?

Not always. Pricing shifts, staff turnover, and reduced access to familiar partners are common after a roll-up, and that friction often sends clients looking for a more personal alternative.

Is referral marketing still worth the effort in 2026?

Yes, but only if it’s run as a system rather than left to chance. Firms that actively cultivate referral sources and follow up fast see far more consistent results than firms hoping referrals happen naturally.

Why does niche specialization matter more as roll-ups increase?

Because generalist, PE-backed platforms rarely go deep into any one industry’s accounting quirks. A firm that owns a niche, like dental or construction, can defend its position on expertise even against a much bigger competitor.
