AirMason

Where AirMason fits

  • US and multi-state employers that want a branded, searchable handbook employees actually open
  • HR teams collecting e-signatures and audit trails without a full HRIS policy module
  • Companies with under 100 employees that will pay $999/yr instead of a lawyer-only Word file
  • Ops teams that will import employees through REST or SAML rather than retyping the roster

Where they pull apart

AirMason

Stands out: Unlimited digital handbooks, signatures, versioning, and reminders sit on Startup. Employee import via CSV, REST, and SAML is on the plans table, with SSO called out as included.

Watch out: Annual billing saves up to 44 percent versus monthly. Copywriting, creative services, content migration, and automated policy updates are add-ons. A dedicated account manager is not on Startup.

Not the right fit for

  • A five-person shop that only needs a free Word handbook download
  • Enterprises that need attorney-of-record policy drafting as the core SKU rather than an add-on

SixFifty

Stands out: Subscriptions include unlimited users, a handbook builder covering all 50 states, and locality coverage for places such as San Francisco, Chicago, New York City, and Seattle.

Watch out: Starter covers one state and up to 100 employees. Growth at $350/mo covers up to 15 states, and larger employers need a custom Enterprise quote.

Not the right fit for

  • Employers with more than 300 employees or more than 15 states, who need an Enterprise quote
  • Employers outside the US whose policies are not US state and city labor law

SixFifty

  • Handbook and policy coverage that names specific cities, not just states

  • Capterra's SixFifty listing has no verified reviews
  • The vendor is explicit that the product is not a substitute for your own attorney
