Treat paper as brand risk, not admin
Your client hired your agency, not a network of subcontractors. When a launch slips, a staging URL leaks, or ownership of a plugin is disputed, the conversation lands in your inbox. Paper is how you decide in advance who can speak, who owns the files, and who pays to fix a defect after go-live. Agencies delay it because the pipeline is hot. That is exactly when it matters: a pilot still exposes names, brand files, and credentials.
If you cannot point to a signed assignment of IP and a written change process, you do not have a white label model. You have a freelancer with extra steps.
