Why book online? Nowadays, customers expect to be able to book appointments or courses conveniently and easily online. A recent study found that over 70% of users in German-speaking countries prefer to choose a service provider that offers online appointment booking(GetApp, 2023). At the same time, over half of all bookings are made outside of normal opening hours - so thanks to online booking, interested parties can make reservations around the clock.
But not every online booking system is suitable for every company. If you are not yet using an online booking system or would like to improve your existing tool, you should pay attention to certain key functions. If you choose a solution too quickly, you risk unpleasant surprises - from double bookings to data protection problems. The right online booking system prevents such problems, simplifies your processes and minimizes downtime and complications.
One of the most important functions is automated customer communication via the booking system. Your booking tool should immediately send booking confirmations by email and send automatic reminders before the appointment. Why is this so important? For one thing, customers expect this service - a full 75% of respondents said they particularly appreciate reminders and confirmations. Secondly, appointment reminders drastically reduce no-shows: up to 75% of all missed appointments can be prevented with friendly automatic reminders by email. This means less idle time and higher customer satisfaction. So make sure that the system supports personalized notifications. This will keep your customers informed at all times - without any manual effort on your part.
Numerous e-mail templates are integrated into edoobox, which are sent automatically when certain events occur. These include booking confirmations and appointment reminders. The templates can be customized and provided with additional information or attachments.
Another key success factor is the ability to offer gift vouchers and discount promotions directly in the booking system. Vouchers are not only a popular product with your customers, but also strengthen customer loyalty and generate additional revenue. Studies show that vouchers not only provide additional customer service but also increase loyalty(Mittelstandsverbund, 2023). For example, new customers can be attracted by a welcome discount, or existing customers are happy to receive a voucher as a thank you. It is important that your online booking system has an integrated voucher module: Customers should be able to buy vouchers online and redeem them directly at the time of booking. A discount code system for promotions (such as early booking discounts or "refer a friend" promos) is equally beneficial. Such features help your business grow by attracting new customers and retaining repeat customers - a real competitive advantage over providers without a voucher option.
Your online booking system should integrate seamlessly into your existing website, both visually and technically. In concrete terms, this means that the booking form should be embedded on your own website and be able to be adapted to your corporate design (colors, logo, fonts). Visitors will immediately notice if they are redirected to a third-party site to make a booking - a seamless experience, on the other hand, looks professional and trustworthy. So ask yourself: Can the tool be adapted to the design of my website?(Website consultant, 2023)
A responsive design is also essential so that customers can book just as easily on mobile devices as on a PC. More and more bookings are being made via smartphone, so a booking system that only runs smoothly on a desktop should no longer be used today. "A booking system is useless unless it is optimized for all devices," warns an industry expert (Billetto, 2023). Make sure that appointment overviews and forms are clearly displayed on smartphones, tablets and desktops and that operation remains simple (e.g. large buttons, short loading times). The smoother the user guidance, the higher the conversion rate - in other words, more website visitors actually complete the booking instead of abandoning it in frustration.
From June 2025, accessibility will also be required by law (BFSG). Your booking system should therefore be designed in such a way that people with disabilities can also use it without any problems - e.g. through keyboard operation, a read-aloud function or clear contrasts. This not only improves accessibility, but also the user experience for everyone. With edoobox, you are already well prepared: the online booking system meets all accessibility requirements and supports you in implementing the BFSG.

A good online booking system is characterized by the fact that all appointments are recorded and managed centrally. Ideally, it offers a clear calendar in which all bookings are entered in real time and availability is clearly visible. This prevents organizational errors such as double bookings or overlapping appointments. Anyone who has been using several separate calendars or even paper appointment books knows the risk: without a central, synchronized system, double bookings can quickly occur. Therefore, look out for functions such as automatic calendar synchronization (e.g. synchronization with Google Calendar/Outlook) and the ability to manage resources and personnel in the system. This allows employees and customers to see which slots are still free at any time. An all-in-one booking system should also make changes visible to all users in real time - if customer A reschedules their appointment, this slot is immediately bookable again for others. With such a central calendar solution, you increase planning reliability and avoid chaos. The result is punctual processes and satisfied customers who appreciate your professionalism.
The edoobox online booking system offers such a calendar and makes it possible to display courses, seminars and events with fixed terms or free choice of dates. Participants immediately see the available places and can book directly, which makes administration much easier.
An online booking system should definitely offer integrated payment processing. Today's customers expect to be able to pay online directly when booking - whether by credit card, PayPal, instant bank transfer or other common methods. This has several advantages for you: Prepayment secures your turnover, reduces no-shows (those who have already paid are more likely to show up for their appointment) and saves time-consuming recalculations or cash payments on site. It is important that the system supports multiple payment options in order to cater to different customer preferences. Some may want to pay by card, others via online banking or wallet - give your customers the choice so that payment is as convenient as possible for them. Also pay attention to security (keyword SSL encryption and GDPR compliance for payment data). Good booking software automatically collects the payment, confirms receipt of the money and notes it directly. This allows you to keep an overview and your customers have the good feeling that everything is settled as soon as the appointment has been booked and paid for.
Last but not least, make sure that the provider fully complies with European and, if applicable, Swiss data protection laws. Personal customer data must be processed securely and in accordance with the GDPR. A system such as edoobox, for example, complies with both the EU GDPR and the Swiss DPA. Also check where the servers are located and whether order processing contracts are offered. Data protection is a must - your customers trust you with their data.
In addition to these six essentials, there are additional functions that can also make the difference - especially if your business is growing or you want to offer a special service:
A powerful booking system should allow you to configure courses flexibly (different categories, prices, dates) and manage all participant data centrally. Changes such as course location or time can be communicated to all participants with just a few clicks. edoobox offers up to ten price categories per course, waiting list functions and collective registrations - ideal for dynamic course formats.
Your booking system should be able to grow with your requirements. You may start with just a few courses and participants, but what if your offering expands? A scalable system can also cope with a larger course program or additional locations without sacrificing performance. Practical experience shows that the right software even facilitates international expansion - with edoobox, for example, you can manage courses in over 20 countries with country-specific settings. You should therefore look out for flexible modules, user limits and the option to book additional functions as required.
Especially for small companies without their own IT department, competent customer support is worth its weight in gold. You should receive help quickly if you have questions or problems - ideally in person in your own language. Many providers advertise with chatbots or forums, but nothing replaces an accessible contact person. One edoobox user review sums it up: "Very good online booking system with great customer service - this high quality of service is rarely found elsewhere!"(https://www.edoobox.com/erfahrungen-mit-edoobox). So take a look at which support channels (telephone, email, live chat) are offered and read testimonials from other users.

Companies that focus on such solutions early on can position themselves as innovators and win new customers more easily. Let's summarize: Ensure customer-friendly communication, retain your clientele with vouchers, integrate the system perfectly and barrier-free into your website, manage all appointments in a central calendar, make sure you have a simple payment solution - and meet the highest data protection standards. With these six essentials plus a few hidden game changers, you'll be one step ahead of your competitors. Start now, because the figures speak for themselves: a large proportion of your target group already wants this option today(GetApp, 2023). With a well-equipped online booking system, you are equipped for the future and offer a service that will bring lasting benefits to both your customers and your business.
