AbsenceResources
Stands out: The same program includes ADA and pregnancy accommodation administration, including PWFA, plus state family leave. ComPsych says decision turnaround is under 2 days and that it has more than 5,700 absence customers.
Watch out: This is an administration service with software, not a system your HR team configures alone. The FMLASource name changed on 16 October 2025. No price is published.
Not the right fit for
- Employers outside the United States
- HR teams that want to make every eligibility decision themselves in their own software
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
