An online booking and appointment system, built for the way you work
Every phone call to book an appointment is time you are not working. We build booking systems where clients see the free slots, book on their own, pay if needed and get a confirmation, while you see the whole schedule in one place.

What a booking system needs
- 01
Free slots, always right
Clients only see the times that are really free, per service, room or person, so double bookings do not happen.
- 02
Booking in a few steps
Service, time, details, confirmation. On a phone, and without an account when one is not needed.
- 03
Payment or a deposit
Card payment when booking, a deposit or payment on the day, depending on how you work.
- 04
Reminders
An email or SMS before the appointment so clients remember it, and an easy way to change or cancel.
- 05
A calendar for the team
Every booking in one schedule, per person or room, with blocked times, leave and holidays.
- 06
Connected to the rest
To your site, your calendar, payments and invoicing, or to a web app for clients and jobs.

Frequently asked questions
Why not use a ready made booking platform?
For many businesses a ready made platform is fine, and we connect it to your site. A system of your own pays off when your rules do not fit standard packages, when you do not want a fee per booking or when you want your clients' data in your own hands.
Can clients pay online?
Yes. Card payment through a payment provider, in full or as a deposit, depending on the service.
Does it send reminders?
Yes, by email or SMS. SMS needs an account with an SMS provider, which charges per message.
Can I add it to the site I already have?
Yes. The booking system can open from your existing site or be the home page of a new one.
Will there be a mobile app as well?
It works in the browser of every phone and can be added to the home screen like an app. An app for the App Store and Google Play is something we discuss separately.
How much does a booking system cost?
It depends on your rules: how many people or rooms, payments, reminders and integrations. Tell us in the brief how you take bookings today and we send you a clear proposal with what we will build, when and at what cost.
