Payroll Stickiness Drives Verticalization
Jeremy Zhang, CEO of Finch, on building a universal API for employment systems
Sticky payroll markets create room for many winners because the real prize is not the first payroll sale, but the long chain of add on products that follows. Once a business runs payroll in one system, that system becomes the place where employee records, deductions, and money movement already live. That makes benefits, retirement, workers comp, and time tracking much easier to sell on top, even if only a few hundred customers are captured in one niche.

Payroll is unusually hard to replace because it sits at the center of pay runs, tax filings, and employee records. In practice, that makes it the source of truth for the rest of the employment stack, so adjacent products plug into payroll rather than the other way around.

Verticalization follows naturally from that stickiness. Gusto starts with payroll, then layers on benefits and other back office tools. Contractor payroll platforms use the same pattern, adding compliance software, wallets, faster payouts, lending, and insurance on top of recurring payroll workflows.
-
Business consolidation does not remove technical fragmentation. Finch notes roughly 6,000 U.S. HR and payroll systems, with the top 10 covering only about 55% of the market, and even large consolidators like ADP still contain many underlying payroll products. That leaves a durable need for an integration layer.
The next phase is deeper bundling around the payroll record itself. As more vertical SaaS companies and embedded payroll providers add payroll, the winning platforms will use that foothold to sell more workflow software and financial products, while infrastructure players like Finch become more valuable by stitching together an increasingly fragmented system map.
