One dashboard for every booking, filterable by city, status and technician.
Assign a technician. Only technicians in that city show up.
Quote approval. The shop sends a quote, and the customer approves it before any work begins.
Notes. Internal notes, or notes the customer can see.
Settings in one place. Pricing, opening hours, slot capacity, cities, delivery fees and legal pages are all managed here, so customers always see quotes and slots that match how the shop really runs.
