The free-viewer model runs through everything the platform does:
Your organization has managers and viewers as distinct roles; only managers consume the seats your plan includes.
Anyone can be given viewer access to the sites they work at, with no per-person charge — ever.
The distribution portal and scan-to-SDS QR codes let people outside your account read sheets with no login at all, which is the ultimate free viewer.
Because viewing costs nothing, you can hand out access as widely as safety requires instead of rationing it to fit a plan.
The result is a pricing model that lines up with the law: you invest in the people who produce compliant sheets, and everyone who simply needs to read one does so for free.
Unlimited free viewers on every plan, including Free. You only pay for manager seats.

Invite the whole workforce — you only ever pay for the people who author.
