Open Source CRM Software
The CRM is the system of record for every deal and conversation, which means this one database quietly becomes the company itself - lose it or get locked out, and the pipeline goes dark. Per-seat SaaS pricing also punishes you for growing the team that depends on it most. The open source options here put that customer history on infrastructure you control, so the record of who your business is never lives behind someone else's paywall.
