Buying Schemity for a team?
Team purchases usually get stuck on one of four things: paying by invoice or purchase order instead of a card, activating on machines with no internet access, clearing a security review, or licensing more than a handful of engineers at once. None of that is automated on this site yet - tell me which one you're hitting and I'll sort it out with you directly.
Still a one-time purchase. What gets negotiated is volume and paperwork, not a per-user meter.

After the trial, offline design keeps working and your workspace JSON stays on your disk - nothing is deleted or locked away. What pauses is the live-database half and the Context Views built on top of it, until a license unlocks them again. Existing workspaces stay fully usable - only creating a new workspace is gated.
