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
Stiira
Stands out: The same company sells a separate edition to third party administrators, with implementation starting at $2,995. The employer page says implementation typically takes 5 to 6 weeks and that employee self service is included.
Watch out: The subscription fee is quoted, so budget it from a demo on top of the implementation fee. No HRIS product names are listed.
Not the right fit for
- Employers outside the United States
- A buyer who needs a published per employee price before implementation
