Portability Premium

Portability Premium is the price an agency pays, in migration hours and client disruption, for every layer of its delivery pipeline that cannot be lifted out and moved to another provider. It reframes stack selection: the question is not which CI/CD or hosting tool deploys fastest, but how much of the client's release process survives a forced exit. A pipeline built on Git-triggered deploys to any SSH server travels cheaply; one wired into a single vendor's proprietary build steps does not. The premium compounds across a retainer portfolio, because each client adds another environment to re-plumb. The same logic now applies to agentic layers: MCP servers can silently rewrite the instructions an agent follows after approval, so an automation chain can drift without anyone on the delivery team signing off. Agencies that price portability into architecture decisions keep negotiating room on hosting and inference costs as client compliance demands shift.
