In the online booking settings, you can precisely determine whether and how your customers can book appointments online with you:
- General Texts
- Booking Texts
In the online booking settings, you can precisely determine whether and how your customers can book appointments online with you:
In the appointment settings, you can customize the appointment booking according to your wishes.


In the time limits, you can set important time periods for your online booking.
Example of common time settings:
In the registration settings, you can determine whether and how your customers can register themselves on your online booking page.
Example of common registration settings:
In the General Booking Settings, you can make the most important basic settings for your online booking.
In both cases, clicking on the desired time creates an appointment draft, which from that point on is no longer bookable for customers and already appears to colleagues as a "dotted" draft in the calendar. This makes unnoticed double bookings in the calendar impossible. However, to ensure that the appointment becomes available again after an improper cancellation of the booking, the draft is automatically deleted after the reservation duration.
We recommend not setting the time period too short, so that your customers have enough time to book the desired appointment, even if something comes up for them in the meantime, for example.
Example of common general settings:

In the invoice design, you can define how your receipts and invoices are formatted.
Enter your company's key data here. If not specified otherwise, the location address will be used. Only fill in this field if your location address differs from the address of the invoice issuer shown on the invoices.


You can upload a logo here. Logo graphics should be black and white and have high contrast so your receipt printer can display them correctly.
If you want to display additional information in the header area of the receipt, you can enter it here. In addition to freely selectable text, you can also use text placeholders. If you use the text placeholders "Customer Name" or the customer's address fields, this data will be taken from the customer file. The prerequisite for this is that you have created these customer fields in the customer settings and your staff fills them in carefully. You can find instructions on creating and integrating this data here.
If you want to display additional information in the footer area of the receipt, you can enter it here. At this point, for example, you can draw attention to online booking or current promotions.
You can design the appearance of your receipt yourself. You can learn more about receipt structure here.
Please note that this is a complex setup. If used improperly, receipts may not be able to be printed.
In principle, a receipt is available for each invoice, which can be issued via your receipt printer. In addition, you can create invoices in A4 format. Once this function is enabled, you will receive a new button in the cash register, through which you can send A4 invoices as PDF either by email to the customer or print them on a suitable printer.
Example of an A4 invoice

If you offer the payment method "Invoice", you can store a custom invoice footer for this payment method. Here you can enter your bank details and further payment instructions. This information will only be printed on the invoice if the customer pays by invoice. If another payment method is selected (e.g. "Cash" or "Card"), the footer you entered under "A4 Invoice Footer" will be used.
If you want to send A4 invoices to your customers, you can trigger email delivery during the checkout process. The email text is a standard text.
If you want to write your own text, you can do so under Settings > Invoice Design > Email. Here too, you can use placeholders to insert, for example, the customer name.

With Stripe, you can accept online payments via credit card, Apple Pay, Google Pay, TWINT, Klarna and SEPA direct debit.
You can find all information on how to set up Stripe's payment functions for your online booking in our video.
Update to the video as of 03/2025: In the current version of Stripe, the required codes can be found using the search term "API" in the search field at the top of the Stripe overview page:

In Stripe, the desired payment methods (credit cards, Klarna, Twint, etc.) can be found via the "Payment Methods" menu item. The easiest way to reach this is to enter this term in the search field:

Here you can select the desired methods from the extensive list. In the Belbo online booking or in the shop, only those payment methods can be offered that are also activatable in Belbo. In Belbo they must also be activated under Settings > Online Payment > Stripe:

If you want to activate online payment via PayPal, you can find more information here.
So that your customers automatically receive their money refunded in case of a cancellation, we recommend depositing a minimum credit balance in your Stripe account settings:

You can customize or supplement numerous texts in the online booking.
Some of the texts within the booking are global and cannot be changed. However, you can determine whether you want to use the informal "you" or formal "you" form for these texts.

If you link the online booking so that your customers must log in first before they can book online, you can edit the start page text.

Supplement your footer with important information about your business. This includes your website, address, or a link to your product shop.
Tip: Do not publish your phone number here. Your customers should book an appointment online themselves instead of calling you. If you want to make individual services bookable online only after telephone consultation, use the appropriate option in your services instead.


If you leave both fields empty, no footer will be displayed in your online booking.
You can supplement the online booking at various points:





You can offer your customers who book appointments online the option to pay online via PayPal.
If you do not yet have a PayPal merchant account, you will need to set one up first. This process takes only a few minutes. Please note that a private PayPal account is not sufficient for receiving payments.
Click on the PayPal business account page and first click on "Open a business account" and enter your information in the following steps. Then confirm the setup by clicking on the link that PayPal will send you to the email address you provided.
To set up online payment with PayPal, you will need the API credentials of your merchant account. The API is a programming interface that allows Belbo Calendar to communicate with your merchant account and verify payments.



Your PayPal merchant account is now linked to Belbo Calendar and can be offered as a payment option for appointments and vouchers.
To activate online payment, please continue on this page.
In the customer overview, you can see all newly registered and entered customers in the "New Customers" field. You can see new registrations from the start and can remove them directly by clicking the "Delete" button and add the customer to your existing list with their email address. This way you avoid duplicate customers. With a simple OK, the customer is transferred to the master list.
