How to Build a Custom CRM System using Prisma & PostgreSQL

Managing client relationships requires a robust database structure. Here is how we design a CRM schema in PostgreSQL.

1. Lead and Interaction Schemas Define clear relations between leads, communication events, and assigned team members to prevent data fragmentation.

2. Index Optimization Create indexes on search columns like email and status to ensure query speeds remain fast.

3. Slack & Email Notifications Trigger automated alerts using serverless webhooks whenever a lead status shifts to won or quotation sent.
