Build vs buy: when does in-house billing stop making sense?

Plenty of providers start with a homegrown script that rates CDRs and produces invoices. It works until it doesn’t. The usual breaking points are a second switch, a new tax requirement, a customer asking for a portal, or the one developer who understands the code leaving.

Questions worth asking before deciding:
  • Who maintains it when something breaks at month-end?
  • What does an error cost in credits and support time?
  • How long would a new feature take to add?
This build vs buy comparison lays out the trade-offs clearly. Did anyone here build their own and later switch?
