1. Coverage breadth. All 50 states plus the EU minimum. Anything less leaves blind spots your users will find first. 2. Update velocity. New state laws land monthly.

Regulators and litigants both ask "what did you know and when." Log everything. 5. Multi-product support. One policy engine across your apps, not per-app spreadsheets. 6. Price scaling. Per-seat SaaS should scale with your team, not with your user count. Watch for usage-based traps. Sources: Congress.gov, NCSL The meta-criterion: does it reduce legal review hours?
