Roles
A job passes through more hands than the person who priced it. The owner, the estimator, whoever answers the phone, the crew on site and whoever does the books all work from the same document — each seeing the part of it that is theirs.
Capabilities
Four seat types, ten actions — the same contract the product prints on its Team page. Enforcement arrives with multi-seat accounts, so the matrix is published before the switches are.
Workspaces
Every pair of hands a job passes through, and what each of them comes here for.
Questions
No. A workspace starts with one full seat, and most solo operators wear several of these hats in the same afternoon. The roles describe how the document is used, not who you are allowed to be.
Teamwork
Documentation
Start with one seat and the whole document chain, and let the crew and the client work from a link. Multi-seat lands on this same workspace.
