Tay Performance

Build

• A vehicle picker that goes from make to model, generation and variant, and turns any car into a service with a price and a duration.
• A pricing engine based on vehicle class, glass surface, tint type and labour, which the owner edits himself.
• A check of the French tint rules for 2026, shown to the client before booking.
• A booking flow with confirmations by email and by SMS through Twilio.
• An admin panel with the queue for the day, job statuses and price publishing.

Backend

• Supabase with Postgres, Auth with row level security, Storage, Realtime and Edge Functions.
• An availability engine that holds a slot while the client finishes booking. The database itself refuses double bookings.

Launch

• SEO with structured data, metadata and performance work, plus a Google Business page created and linked to the site.

• Slot holds that survive two people booking at once. Postgres guarantees that two clients can never take the same bay at the same time.
• Pricing the owner can change alone. He should never need to call a developer to update a price.
• Five days from spec to production. The whole system shipped in that window.

A client now gets a price and a confirmed slot in under three minutes. The owner sees the cars of the day on one screen and the phone rings less. More clients come in through the site, and several hours of manual work are gone every week.
