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
Pulpstream
Stands out: An AI recommendation engine suggests leave decisions from regulations and company policy, and intermittent leave is tracked in hours. The leave page shows logos for Workday, UKG, ADP, Dayforce, and others.
Watch out: Pulpstream is also a risk and case workflow platform, so leave is the lead offer on the leave page but not the only module. There is no public price.
Not the right fit for
- Employers outside the United States
- A buyer who wants a fully outsourced leave administrator instead of software
