    CRM & Business Systems

    One central system for customers, inquiries, quotes, contracts, projects and communication — on Postgres with Row-Level Security, a custom admin panel and a clean audit trail.

    Problem

    Growing businesses run on fragmented tools: inbox for leads, spreadsheets for quotes, WhatsApp for status, a cloud folder for documents. The gaps create friction, errors and lost leads.
