Every software build ends with the client owning what was built, the code, the specification, and the documentation behind it. Nothing is licensed back at a recurring cost designed to make a business pay twice for its own asset.
Scope gets set at the quoting stage and revisited only if the project genuinely changes shape, not renegotiated over every small addition. The four-stage process behind every build, planning, design and execute, testing, and reporting, keeps that scope visible throughout, not resolved only at the final invoice.
