The End of the Hourly Billing Era

For decades, the "Big Four" professional services firms—PwC, Deloitte, EY, and KPMG—have relied on a model of hiring large cohorts of junior staff to perform routine tasks, billing clients for every hour worked. AI now threatens to automate these functions, potentially allowing clients to move work in-house.

The Pivot: PwC is shifting toward "outcomes-based" pricing and automated tools.

PwC One: On Thursday, the firm is launching an AI platform offering six automated services, including an "anomaly detector" for sustainability data and M&A due diligence tools.

Pricing Revolution: Griggs expects services to eventually be paid for via annual subscriptions or consumption-based models, sometimes without a "PwC person in the loop" during initial stages.
