Shipped software needs a defect window, monitoring and a way to change it without turning maintenance into endless new scope.
Keep production stable. Record incidents. Ship fixes inside the contracted window. New modules are a new estimate—not a silent expansion of “warranty”.
Uptime, backups and the jobs that must not fail silently (imports, posting, device callbacks).
Bugs in agreed scope are fixed. “We also need a new role” is a change request.
Access reviews, dependency updates and deployment notes. Private data stays in the environment you chose.
If we added RAG or an agent, we refresh the corpus and prompts on a schedule—you still own the source documents.
Delivery manager: Owns the backlog after go-live and the release notes you can give your users.
Engineers: Backend, clients and warehouse devices—the same skills that built the system.
