Your model is solid and i really like it a lot.
Here are my recommendations:
Improve Data Normalization & Flexibility
Customer-Reviews Relationship: Instead of linking reviews directly to a customer, consider linking them to an appointment.
This ensures reviews are specific to the services provided in each session.
Sales-Payment Structure: Currently, sales and payments are separated, which is good for tracking deposits and multiple payments per appointment.
However, you should allow partial payments and track payment methods (cash, credit card, etc.) to support flexible payment scenarios.
Strengthen Relationships & Business Rules by providing the following
Discount Management: If you plan to have multiple discounts (e.g., first-time customers, seasonal offers, loyalty rewards), consider a separate Customer_Discount table to track which customers qualify for which discounts.
Service Pricing Model: Some services may have different pricing tiers (e.g., microblading for first-time vs. touch-up pricing).
You could:
Add a Price_Tier column to the Service table
Maintain a Service_Pricing_History table to track price changes over time.
Whats your plan for Scalability & Future Growth
Appointment Status: Add an AppointmentStatus column (Scheduled, Completed, Cancelled, No-show) for better tracking.
Customer Engagement Tracking: If you plan to engage with customers for retention, consider a customer interaction history table to store communications (e.g., email reminders, promotional offers sent).
I really think this is a great and solid business model that will thrive and scale if done dilligently.
