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
Sedgwick LeaveLink
Stands out: LeaveLink is sold as SaaS separate from Sedgwick's outsourced absence book, including an employee and manager portal and premium tracking while someone is on leave.
Watch out: Sedgwick is also a large disability and leave administrator. Confirm the contract is the enterprise software edition, not a bundled claims service. No price is published.
Not the right fit for
- Employers outside the United States
- Small teams that want a simple per employee monthly tracker
