Answer six quick questions - your trade, who works with you, where, your hours, your services and the small print - and FullDiary gives you a booking page at your own address. The answers come filled in for your trade and you change what you like. Put the link on your website, your Instagram bio, your WhatsApp - anywhere customers already find you.
A customer opens it, chooses a service, picks the person they want (or lets you decide), sees only the times that are genuinely free, and books. They get a confirmation email with a calendar file, and a link to manage or cancel; you get the booking in your diary and an alert with their details. Nobody has to install anything or create an account.
Every booking lands in one live diary that you and your staff run the day from. Reminder emails go out before the appointment so people turn up, on every plan, and a customer can move their own booking from their confirmation page while it is still outside your cancellation window.
