The honest answer to "why don't we just build our own CRM" is usually that the team does not want a CRM at all. They want one workflow that the current tool handles badly, and the licence cost is the most visible symptom of that frustration.
When a client brings us this question, we ask them to name the single process that hurts, with a number attached. Often it is something like quotes taking two days because pricing lives in a spreadsheet, or renewals slipping because the data sits in three places. That one thing can usually be built as a small service that reads from and writes back to the CRM they already pay for. They keep contacts, permissions, audit history and reporting, which are the parts that look simple and quietly consume most of a custom build.
A full custom CRM makes sense in fewer cases than people expect: when the core object is not really a contact or a deal, or when the sales process itself is the product. Otherwise the larger cost is rarely the build. It is the years of maintaining features the vendor would have kept current for you.
