Instant Data Sync
LEAN automatically pulls data from your existing payroll and HRIS systems so nobody has to manually look it up.
From leave policy to a
decision you can defend
LEAN applies state and employer rules to leave facts, calculates entitlement and pay, and records the sources and reasoning behind the result.
For PEOs, HR platforms and leave teams
Covering 45+ laws & statutes including
FMLA, WA PFML, CO FAMLI, NY PFL, CA SDI
Colors show whether that part of leave is approved, waiting on information, not covered, or temporary — for each stretch of time.
From disparate source systems to a single answer
Stop piecing leave decisions together by hand
The facts already exist across HRIS, payroll, case documents, and policy sources. LEAN assembles what is known, asks only for what is missing, applies the rules, and returns one decision with the reasoning attached.

Why isn’t wage replacement covering Riley’s week of Feb 10? Job protection already looks approved.
Job protection is approved for that week. Wage replacement is not covered because Riley is serving the program’s waiting period . Riley’s hours and certification are already satisfied .
WA does not pay benefits for hours claimed during the waiting period, and its ordinary weekly proration rule does not apply to that waiting-period week .
This is the same status explanation available from Engine’s timeline.
- Timeline See job protection, wage replacement, and benefits develop independently over time.
- Reason Open the rule, facts, and cited source behind an approved, waiting, or not-covered period.
- Amount Inspect the wage history, exclusions, rates, and offsets behind weekly pay.

Policy lifecycle
Policy changes should be testable
Draft the rule in language a policy expert can review, test it against saved cases, choose when it takes effect, and preserve the decisions made under earlier versions.
Draft a reviewable rule
Build structured rule clauses using the terms your statute or handbook already uses.
Test it with saved cases
Run reusable scenarios with expected outcomes before a policy change reaches live cases.
Approve when it takes effect
Save changes as a draft, put them through your review path, and set the effective date explicitly.
Replay what applied then
Return to an earlier date and see the facts and determination available at that time without replacing the recorded result.
The audit trail
Separate complex rules. Simplify the explanation.
A single leave request can trigger wildly different rules for job protection and wage replacement. LEAN tracks every parallel logic path simultaneously, showing you exactly what met the threshold and what blocked the payout.
Every determination comes permanently attached to its own automated compliance proof. Get instant visibility into the exact policy source, statutory rules, and data ranges that drove the result — no reconstruction required.
- Instant Status Justification Every single approved or denied period explicitly states its underlying rule, completely eliminating guesswork for HR and employees.
- Full Pipeline Visibility Easily trace which requirements were met, which were intentionally skipped, and which data gaps are still holding up a determination.
- Decoupled Eligibility Routing Process concurrent policies independently. Approve job protection instantly while safely holding pay for mandatory waiting periods.
LEAN logs the full structural audit trail the exact millisecond a decision is made—ensuring your compliance records are always immutable.
