You can customise every single word on your online booking.

Meaning if you are only using English you can modify the words to your style.

Similarly, if you are using multi-language features then you can customise each language.

Online Booking Text

you can also customise all the text that appears on the wizard - for each language:

To do that, navigate to Settings > Online > Language Customization

Select 'Online Booking' (and language) and then select the text by clicking it to activate a text box. Make your edits and click the Enter/Return key on your keyboard to save the changes.
