The "service" part can still come from internal sources. Plenty of companies have internal support for internal tooling. With a good foundation of infrastructure and a lean team that knows how to build, not just vibe code, there is most definitely some ROI there.

But yes, this brings us back to the point that simply building the tool is only a small part of the process...and it has often been one of the most expensive parts of the process.
