Custom GPT for Local Business: Real System Prompts That Work (2026)

What a Custom GPT Can Handle

• Pricing questions: "How much is a balayage?" / "What's the price for a large cold brew?"
• Hours and location: "Are you open on Sundays?" / "Where are you located?"
• Service descriptions: "What's the difference between highlights and balayage?"
• Booking guidance: "How do I book an appointment?" (with a link to your booking page)
• Cancellation policy: "What happens if I need to cancel?"
• Product recommendations: "What shampoo do you recommend for color-treated hair?"
• FAQ responses: Anything you've pre-loaded in the knowledge file

• Actual bookings (it can direct to a booking link, not book directly unless you integrate an API)
• Complaints requiring human empathy and decision-making
• Anything involving sensitive personal data
