Bottom line
AbsenceSoft is leave and accommodation management software for US employers that run leave in-house, and for TPAs and PEOs. It is quote-only, with a custom pricing proposal after a demo and no trial. Its strengths are the Compliance Engine for 200+ laws and a well-documented public API.
Stands out for: 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 for: 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.
Overview
AbsenceSoft manages continuous, intermittent and ADA leave and workplace accommodations in one platform. The Compliance Engine calculates eligibility against 200+ statutes including FMLA, ADA and PWFA, generates packets and letters, and tracks intermittent usage. Employees request leave and upload documents through a self-service portal, managers see return-to-work dates, and HR can text employees and receive provider faxes in the platform.
The company says it supports 10,000+ organizations and 7 million+ employees, with support staff in the US and Canada who are CLMS-certified. Integrations run through flat files or the REST API with OAuth2 and webhooks, and it lists Workday, UKG, ADP, SAP, Oracle, Dayforce, Okta and JumpCloud among connected systems. AI features cover intake, document review, planning and flagging next steps.

Pricing

The Payroll Calculations module is a separate module, and custom outbound file feeds and API development help are extra-cost professional services. Confirm current terms on the vendor site.

SparrowSparrow pairs leave software with a dedicated leave specialist who handles filings for you, covering the US and Canada, while AbsenceSoft is software your own team or TPA runs.
AllVoicesAllVoices tracks leave and accommodation requests inside a broader employee relations case system, lighter than AbsenceSoft's statute engine.
HR Acuity focuses on employee relations investigations, useful when accommodations sit inside ER cases rather than leave administration.
Calamari is a mid-market leave and time tracker for PTO, not a compliance engine for FMLA and ADA casework.
