Have the AI read this prompt and make sure it adds in the specifics for your business so it can grow. THE CONTRACTOR INVENTORY & OPERATIONS HUB - UNIVERSAL AI PROMPT What this builds: A full-stack inventory management, job scheduling, automated purchasing, and build-tracking web application purpose-built for home service contractors. It connects to your CRM (Jobber), scans your supplier invoices from email (Outlook), auto-creates equipment builds when deals close, tracks payments owed to vendors, and alerts your team when stock runs low. It is best suited for any trade that installs physical equipment or uses materials on job sites - HVAC, plumbing, electrical, water treatment, pool service, solar, landscaping, pest control, or any specialty contractor with a warehouse and field crews.
