Solo, appointment-based businesses like small nail studios, salons, and home-based service providers often run entirely on WhatsApp. The owner is doing the client's nails with one hand and replying to booking messages with the other — checking availability, confirming times, and texting reminders, all manually. This doesn't scale, wastes hours every week, and leads to double-bookings or missed messages. I wanted to solve the actual bottleneck: turning "can I book with you?" into "you're booked" without the owner lifting a finger, while also addressing the no-show problem with a small deposit built into the booking flow.
