Every engineer, their own secure login.
Add an engineer from your control panel and they get a secure invite by email — their own login, tied to your account and your plan. What they sign off appears in your panel the moment it's saved.
Invite by email
No shared passwords. Each engineer sets their own from a secure, expiring invite link.

The dashboard shows who signed off what, and when — no end-of-week paperwork pile to decipher.

Disable an engineer with one click. Their history stays with your company; their access ends immediately.
Private & secureManage your engineers, done properly
Sign-off records belong to your business, not to whoever happened to do the job. Every engineer works under their own login, every record is stamped with their name, and one login can't be shared around — each account works on one device at a time.
Plans are priced per engineer seat, so the system grows with the team: start with one, add seats as you take people on, and disable accounts the day someone moves on.
