カスタムCRM・社内ツール開発

A production-ready MVP with pipeline management, admin dashboard, and core workflows typically takes 12-16 weeks. That covers discovery, architecture, iterative build sprints, data migration, and launch. Builds with AI features, multi-tenant architecture, or extensive third-party integrations push that to 20-24 weeks — there's no shortcut through that complexity.

Salesforce Enterprise at $165/user/month for 500 users runs roughly $990K over 3 years — before you factor in implementation consultants. A custom build at $150K-$250K plus $1.5K-$3K/month for hosting and support totals $200K-$360K over the same period. You also own the IP and cut vendor lock-in entirely.

Yes. We run parallel systems during migration with automated bidirectional sync between your legacy CRM and the new platform. Historical deals, contacts, activities, and custom fields all get mapped to a clean schema. We validate data integrity at every stage and only cut over when both systems are fully in sync with zero discrepancies.

Row Level Security enforces access policies at the PostgreSQL layer, not in application code. Even if a frontend bug exposes an API route, the database itself rejects unauthorised queries. Policies map to your org hierarchy — reps see their deals, managers see their teams, executives see everything — with audit logs on every access event.

We build REST API integration layers for NetSuite, QuickBooks, Xero, Stripe, and most SaaS tools with documented APIs. For legacy systems without APIs, we build custom ETL pipelines using Supabase Edge Functions and scheduled jobs. Every integration gets tested against production data volumes to confirm it holds up under real-world load — not just demo conditions.

We offer retainer-based support covering feature development, performance monitoring, Supabase infrastructure management, and security updates. Your team can also maintain it independently — the Next.js/Supabase stack uses standard TypeScript and SQL, so any competent full-stack developer can contribute. We provide full documentation and handover training.

Supabase Realtime provides WebSocket-based subscriptions that push database changes to all connected clients instantly. When a rep in London updates a deal stage, a manager in New York sees it within milliseconds. We implement optimistic UI updates and conflict resolution to handle simultaneous edits gracefully, even across unstable network conditions.
