Building BCB CRM: A Lead Management System with Laravel and MySQL

I like your distinction between a lead’s current stage and the history that explains how it got there. In my experience, a stage is most useful when it also points to the next concrete action. A practical addition is to require a follow-up date whenever someone moves a lead to Contacted or Proposal, then review overdue items by owner each morning.

I like that you kept the stage history as its own record instead of just overwriting a status column. One thing worth thinking about as this grows: policies protect who can touch the history, but nothing stops an admin (or a stray seeder) from editing or deleting rows and quietly corrupting the pipeline reports. I've started making history tables append-only at the DB level, a check or trigger that rejects updates and deletes, so the audit trail survives even admin mistakes. Cheap to add now, painful to retrofit once the reports are trusted.
