Can I manage both booking slots and walk-in customers at the same time?

Yes. You allocate a certain number of bays for bookings and keep others open for walk-ins. Walk-ins get a queue number and join the live queue board. The app shows you the current load across all bays — you decide in real time whether to accept more walk-ins or put up a 'full' notice.

What if a customer books but doesn't show up?

The PromptPay deposit (฿50–฿100 is standard) deters most no-shows. If they don't show within 15 minutes of their slot, you can release the slot and mark the deposit as forfeit. Your policy is configurable — some shops apply it strictly, others offer one rescheduling. Either way, the slot is freed for walk-in customers.

Can I handle multiple wash bays and different service types?

Yes. Create separate service types (basic wash ฿80, full wash ฿150, detailing ฿500) each with their own time slots and bay assignments. Basic washes take Bay 1–3, detailing takes Bay 4 which needs a 2-hour slot. The booking system prevents double-assigning the same bay at the same time.

Does the app work for mobile car wash (we go to the customer)?

Yes. Instead of bay-based slots, you set service area zones and time windows. Customers in Zone A can book Tuesday/Thursday 9am–1pm. You see the day's route and can optimise the order of jobs. Payment is collected via PromptPay when you arrive or when the job is done.

No more queue chaos. Just clean cars and happy customers.

Slot booking, live queue board, vehicle status tracking, PromptPay, loyalty stamps, and automated LINE notifications — everything in one app.

Online slot booking

Customers book a time slot — they arrive when it's their turn

Instead of random walk-ins creating unpredictable queues, customers book a 30-minute or 1-hour slot online. They see which slots are still available today and tomorrow. A PromptPay deposit locks the slot. You know exactly how many cars are coming and when — no more 10-car backlog at 9am and empty bays at 2pm. Slot booking distributes demand evenly across the day.

Real-time queue board

Customers see their car's position on the queue — they stop calling to ask

A shareable link shows the live queue board: how many cars are ahead, estimated wait time, and current status. Customers who walk in without a booking get a queue number and can monitor their position from the waiting area or even leave to run errands. You stop answering 'is my car ready?' calls every 15 minutes. Queue board updates in real time as you move cars through the wash stages.

Vehicle status tracking

Mark cars through wash stages — customers get LINE updates automatically

As each car moves from waiting → washing → drying → ready, you tap to update the status. Automatic LINE messages go to the car owner at each stage they care about: 'Your car is now being washed' and 'Your Honda Jazz is ready for pickup.' No staff member needs to remember to call anyone. Customers arrive at the right time — not 20 minutes early or 30 minutes late.

PromptPay payment

Collect payment before or at handover — no cash handling

For pre-booked slots, collect a deposit via PromptPay QR at booking confirmation. Balance at pickup via the same QR. For walk-in customers, generate a payment link with one tap when the car is ready. Payment records sync to your revenue dashboard automatically. End-of-day reconciliation is instant — no counting cash, no discrepancies.

Loyalty stamp programme

Wash 8 times, get 1 free — builds regulars who return every 2 weeks

Car owners who wash regularly are your highest-value customers. A digital loyalty stamp card tracks every wash without physical cards that get lost or forgotten. At 8 stamps, they earn a free basic wash. Customers at 6-7 stamps are motivated to return soon. The stamp programme creates a predictable base of regular weekly/fortnightly customers — your revenue floor.

Revenue & capacity reporting

See your busiest hours, most popular packages, and monthly revenue trends

The dashboard shows: cars washed per day, revenue per day, which wash packages are most popular, peak hours that need more staff, and slow periods to fill with promotions. If Monday afternoon is always slow, you know to run a Monday promotion. If premium detailing is your top revenue item, you know to add a second detailing bay. Data drives the decisions that grow the business.
