NexaCRM — AI-Powered Multi-Tenant Sales CRM

NexaCRM is a production-grade, multi-tenant B2B SaaS CRM built to demonstrate enterprise-level software capability. Built with Next.js 15 (App Router), TypeScript, Prisma ORM, Neon PostgreSQL, NextAuth v5, and Claude AI — it is the most technically ambitious project in the Tech Mag Solutions portfolio.

The core CRM includes full contact management with deal history, activity timeline, and status tracking (Lead → Prospect → Customer → Churned). The pipeline page features a live drag-and-drop Kanban board built with @dnd-kit/core across 6 stages (Lead, Qualified, Proposal, Negotiation, Won, Lost) — stage changes persist instantly to the database via PATCH API.

AI features powered by Claude AI (claude-opus-4-6): AI Lead Scoring generates a 0–100 score for any deal with reasoning and a specific next action recommendation. AI Email Drafting writes personalized follow-up emails based on contact profile, deal stage, and last activity — editable in a modal with one-click copy. Both features gracefully fall back to rule-based responses when the API key is not set.

The analytics dashboard includes a pure SVG monthly revenue bar chart (no chart library), pipeline funnel visualization, win rate calculator, and top deals leaderboard. The settings module covers profile management, team member listing, and a subscription upgrade UI with 3 pricing tiers.

Multi-tenancy is enforced at every database query — all data is scoped to the user's organization ID. NextAuth v5 middleware protects all /dashboard routes. Role-based access: OWNER, ADMIN, MEMBER. Stripe-ready subscription model: Free, Starter ($29/mo), Pro ($79/mo), Agency ($199/mo). Full seed data: 10 contacts, 8 deals across all pipeline stages, 15 activities.
