AbsenceSoft
Stands out: The AbsenceSoft Compliance Engine tracks 200+ federal and state leave and accommodation laws and stacks concurrent leaves, and the Payroll Calculations module applies state paid leave offsets per pay period. The API is publicly documented in OpenAPI 3.1 at absencesoft.stoplight.io, with Employee, Case, Employer and Communications APIs and webhooks.
Watch out: There is no public price, and custom outbound file feeds and API build work cost extra. Payroll Calculations produces estimates and export files, not payments, so payroll still runs in your own system.
Not the right fit for
- Companies outside the US, since the engine covers US federal and state law
- Small businesses that only need PTO tracking
Tilt
Stands out: AbsenceIQ is the vendor leave intelligence system, and Tilley is an AI phone assistant sold as a paid add on. Essentials lists all leave types and state PFML programs.
Watch out: Add ons change the headline price: integrations, premium support and the Tilley phone assistant are extra on Essentials, and adding premium support brings a $5,995 minimum contract. Coverage is US federal, state and company leave only.
Not the right fit for
- Employers outside the United States
- A buyer who wants a fully outsourced administrator and no internal leave work
