Embedded Payroll Becomes Core Infrastructure
Matt Brown, Co-Founder of Bonsai, on the rise of vertical ERPs
Making employee payroll as easy to embed as contractor payouts expands payroll from a specialist product into a default layer inside vertical software. That matters because contractor tools like Deel and Wingspan solve complex cross border, compliance, and mass payout workflows, while the far larger base of very small US businesses needs simple payroll inside the software they already use to run the business. Adding both inside one product increases wallet share and makes the software harder to replace.

The customer jobs are different in practice. Global contractor platforms bundle onboarding, tax forms, currency conversion, and compliance for distributed teams. SMB payroll platforms like Gusto center on paying domestic employees, filing taxes, and handling benefits, then add contractor support around that core.

Embedded payroll does not erase standalone payroll. It gives vertical SaaS a new module to sell. Payroll has high retention and creates a path to attach payments, lending, cards, and benefits, which is why payroll APIs and embedded products are spreading across software stacks.

The bigger greenfield is the micro SMB. Very small businesses often have one to five workers, and payroll is still a core recurring job. When industry software can run schedules, payments, bookkeeping, and payroll in one place, the addressable market gets much larger than contractor only software alone.
The next wave is payroll becoming infrastructure inside industry software, while the winners above that layer specialize by worker type and workflow. Vertical ERPs will pull simple domestic payroll into the core product, and specialist platforms will keep winning where international hiring, contractor density, and compliance complexity make payroll itself the product.
