DEBIT AI · UPDATED EVERY MONDAY
Who's buying accounting firms — and what those firms are buying next. Private equity, mergers, multiples, and the AI actually being deployed inside the profession.
⚠️ Deal terms and AI-investment figures are as publicly reported, and are frequently partial or re-labeled. Verify before citing. A field guide, not investment advice.

Track B is often the more useful half: when a firm of consequence commits real money and real liability to a tool, that is the best available evidence it has crossed from demo to production.
WEEK OF JULY 13, 2026
Private-equity investments, firm mergers, and platform tuck-ins. Nearly all use an alternative practice structure (APS): the firm splits into a CPA-controlled attest entity and a non-attest advisory entity, and the outside capital goes into the advisory side. That split is the regulatory key that makes the entire wave possible.
Cleveland firm founded in 1919; 250+ professionals across 15 offices in the US and UK. Its first institutional investor in 107 years. The deal includes an "Employee Purpose Plan" extending equity ownership to every employee — not only partners.
→ The standard objection to the roll-up wave is that partners cash out while everyone below them inherits the leverage. This is the first deal explicitly structured to answer it. Whether it becomes a template or a press release is the thing to watch.Apax-backed CohnReznick absorbs the Houston firm (12 partners, 87 staff, founded 1995; energy, financial services, construction, non-profit, benefit plans), adding two Houston offices and one in Galveston. Its second acquisition of 2026, after Smith Schafer in January.
→ Textbook platform behavior: once the sponsor is in, the firm becomes an acquirer. Watch for auditor transitions among HL&B's public clients.The headline deal. Crowe is the #12 US firm (~$1.39B revenue, 5,600+ staff) and was one of the last large holdouts. Majority stake; partners retain a minority. Split into Crowe LLP (attest) and Crowe Advisory LLC.
→ When a firm this size goes, the question stops being whether the model spreads and becomes who's left.A ~$306B-AUM alternative asset manager enters accounting. Atlanta Top-100 firm (~$74M net revenue). Prior backer Broad Sky exits.
→ The mega-funds are now in. That changes the ceiling on what firms can fetch.MDP's first accounting deal. A three-way merger — CPA firm + Partners Risk Services (insurance) + JGH Consulting (transaction advisory) — into a single ~$49M-revenue platform, led by former Baker Tilly US CEO Alan Whitman.
→ Note the shape: not a firm, a platform. Accounting is the anchor, and adjacent high-margin services are bolted on.The first PE-to-PE flip of a US accounting firm. New Mountain bought in at ~$500M (~11×) in 2021 and sold at ~$2B — roughly a 4× return in three and a half years. Revenue grew ~$350M → ~$850M over the hold. Blackstone kept its own stake below 50% for audit-independence reasons.
→ This is the deal that proves the exit. Every sponsor entering accounting is underwriting to this outcome — which is precisely why the pace has not slowed.Broke the size record weeks after Baker Tilly. The capital funded partner retirement obligations, returned capital to current partners, and built an M&A war chest.
→ The clearest statement of what the money is for: retire the old guard, pay the current one, and go shopping.The deal that made PE-in-accounting mainstream — at the time, the largest US firm to take outside capital. Baker Tilly has since gone on the offensive itself (Moss Adams, Anchin).
→ Sponsor-backed firms don't stay bought. They become buyers.TowerBrook–EisnerAmper (2021) started it. New Mountain–Citrin Cooperman (2021, ~$500M/~11×) and Parthenon–Cherry Bekaert (2022) followed.
→ Three of the four fastest-growing US firms are now PE-owned. Whatever else the model does, it moves the growth needle.Technology adoption and investment by accounting firms: production deployments, announced spend, equity stakes in accounting-tech companies, vendor alliances — and the quiet retreats. Priority: the mid-market. Big Four AI spend is well covered everywhere; what a $50–500M-revenue firm actually deploys is not, and that's the firm most readers work in or compete against. Companies marked ATS100 appear on our AccountingTech Startup 100.
The Top 30 firm is putting Basis's autonomous AI agents into its client accounting services delivery — ERP integration, month-end close, transaction processing, reconciliation — across its global team.
→ The strongest class of signal there is: a real buyer, doing real diligence, carrying real liability, in production. Not a pilot, not a demo.A long-horizon agent that carries substantive testing end to end — population analysis, sample selection, evidence collection, extraction, testing, workpaper generation — pausing for practitioner review along the way. Shipped alongside Field Board (a kanban engagement view) and an Agent Review Experience.
→ The category shift, stated plainly: from single-task copilots to agents that sustain reasoning across a whole engagement. This is what "agentic audit" means once it stops being a keynote slide.PwC partnered with OpenAI and deployed ChatGPT Enterprise firm-wide at reported six-figure license counts, becoming a reseller to clients in the process. KPMG committed to a multi-year Microsoft AI alliance. EY built EY.ai and its EYQ internal model. Deloitte moved to agents with its Zora platform and an Nvidia partnership.
→ Treat these headline figures as press releases, not financial statements — they are unaudited, and some is re-labeled IT budget. The deployment count is the real number. The more interesting question, and the one this tracker exists to answer, is what everyone below the Big Four actually adopts.PE capital explicitly directed at technology alongside the M&A war chest.
→ Track A meeting Track B in a single sentence: the sponsor's thesis is the tech spend.Equity, not just licenses. When a firm takes a stake in a vendor — as Citrin Cooperman did with Tellen — it is a far stronger signal than a pilot. Firms buying tech companies outright. The "buy the capability" route. And the retreats: abandoned pilots, quiet write-offs, tools that got dropped.
→ Everyone reports the launches. Almost nobody reports the failures — and the failures are more useful to anyone deciding what to buy. If you've watched a rollout die inside a firm, we want to hear about it.Updated as the database grows. These are working conclusions, and we'll say so plainly if the evidence turns against them.
Practitioners always do. Deals leak, pilots quietly die, and rollouts get walked back long before a press release admits it. If you've seen one from the inside — a deal in diligence, a tool that flopped, a partner vote that failed — tell us. We protect sources, and we verify everything before we print it.
Send a tipTrack B tells you which technology firms are buying. The AccountingTech Startup 100 tells you who's building it — 100 companies across 13 categories, with funding signals. The two lists check each other: when a firm puts money behind a company on the list, the list is doing its job.
