The frantic pace of deal-making in March has officially transitioned the accounting industry from a “consolidation phase” into a “platform war.”
As the first quarter concludes, the narrative is no longer just about who is buying whom, but about which investment philosophy—and which technology stack—will dominate the next decade.

But the cold, hard data tells a different story. Of the 400 verified transactions logged in the CPA Trendlines PE-CPA Deal Tracker™ since 2016, a verifiable 112 — 28 percent — are concentrated in just five platforms: Crete Professionals Alliance, Ryan, Aprio, Sorren, and Ascend.
