Backend Diagnosis The salon's core booking process currently depends on three disconnected sources: WhatsApp, a paper diary, and phone contacts. This creates a high risk of missed updates and makes customer information difficult to retrieve consistently. Priority Issues Appointment information is spread across WhatsApp and the paper diary. Customer information is not stored in a dedicated record. Appointment changes can be missed or duplicated. Staff responsibilities for updating bookings are unclear. Recommended Backend Structure Create four simple operating areas: Customer Records — name, contact details, services used, preferences, notes. Appointment Tracker — date, time, customer, stylist, service, status. Price List — one master version accessible to the team. Follow-Up List — customers requiring confirmation or post-appointment follow-up. Workflow Improvement Every new booking should follow the same sequence: Booking received → customer record checked/created → appointment recorded → stylist assigned → customer confirmation sent → appointment completed → follow-up recorded. Roles & Responsibilities Owner: maintain master price list and oversee backend. Stylist: update appointment status after completing service. Booking owner: ensure every WhatsApp booking is transferred into the appointment tracker. Quick Wins Move the current customer information into one master customer list and create one master appointment tracker. 7-Day Action Checklist Day 1: Create customer database.
