Set up Clamp · Guide 18 of 19

Using Clamp as a sub

Updated Oct 9, 2026

Who this is for. A contractor has invited you to one of their jobs. You get the job's address, the schedule, the shared photos and the job thread in one place, and you agree dates without phone tag. You stay your own business: your hours, miles and receipts are yours, and the contractor never sees them.

Accept the invite

  1. The email reads "[Business] invited you to their jobsite". Tap ACCEPT INVITATION. The link is good for 7 days.
  2. Enter your email and tap Continue.
  3. Add your name and business name if you like, enter the 6-digit code Clamp emails you, and tap Accept invitation.

That sets up a free Clamp account: no password and no card. You land on Jobsites, and the same account works in the Clamp app on your phone. An expired or revoked link says so; ask the contractor for a new one.

Your jobs

Jobsites groups your jobs by contractor, with Jobs and Schedule at the top. Schedule shows your dates across every contractor who uses Clamp. A job marked Finished is done; Updates paused means it's read only.
