A booking flow for a one-man AC technician in Bandung, built for the Contra x Lovable challenge. Customers only see days he is already in their area.
Kang Dedi is a fictional client with a real problem. Every booking took 6 to 10 WhatsApp messages, his days zig-zagged across the city, and customers forgot he was coming.
Adem Service covers the whole path from inquiry to confirmed booking: pick a neighborhood, pick a service, get a live price and time on site, then choose a slot that fits around other jobs and the Friday prayer break.
On the owner side, one dashboard shows today's route, the week by area, every automated message and the waitlist. Messages are simulated in the demo; production would use the WhatsApp Business API.
Details worth a look
- Area-aware slots: mornings in the customer's area, afternoons in the center
- Reminder the evening before with still on / reschedule, no reply gets flagged
- Cancelled slots are offered to the area's waitlist automatically
- Owner dashboard with route map, week view, message log and waitlist
- Impact numbers are labelled as estimates
