Payment methods are activated in Back end but not visible in front

Hi,
I try to use your component for a website about photography business and other pretstations that need to go to customers location. 
I'm testing ... and at checkout page i cant see any payment methods. 
Here is link :  2c-events.com/nos-prestations-express/prestation-france-photo-1

Thanks for help; If you have any trick to use your component optimal for services that include displacement of technicians,; they are welcome.

EDIT : Apologize... a wrong translation of component made mistake. 

Hi Damien,
The reason why payment gateways are not displayed on the Checkout form may be due to one of the following:
1. You are making a booking using an administrator account. For administrators, payment is not required to complete the booking process, so payment options will not be shown.
2. In Configuration → Booking Configuration tab, if you set the "Registered" group as a Special group, users in this group will also not be required to make payment to complete the booking.
3. Also in Configuration → Booking Configuration tab, please check if the "Disable Payment" option is enabled. If this option is turned on, payment will be disabled.
Please check these settings and let me know if you need further assistance.
Best regards,
Dam

Thanks, works fine. But how could i make price based on an address ? As photographer, i need to give displacement cost included in price.

Hi Damien,
I suggest you set up custom extra fields with additional prices. This way, your customers can select their location and the price will be adjusted based on the distance.
If you need any assistance with setting up these extra fields, please let me know.

I understand..but if we take an exemple : an event could be in same department but 5 km ou 130 km from my business location. I need to implement distance calculation and then a pricing based on this. And customers adress may be different from events location 😂...this gives me headache !

Hi Damien,
If you need to calculate prices based on the customer's address, we can implement a custom solution for you. Of course, this would be a paid job.
Please let me know your thoughts or if you would like to discuss further.

Really ? that would be wonderful ! Not exaclty based on customers address but on an address he adds in a custom field. For example a customer ca have his business in Elsass but needs a photo shooting in Paris

Hi,
Could you please describe the formula for calculating the price based on the distance? Once I have this information, I can review it and let you know if it’s possible to implement.
Thank you!
Best regards,

Final price = distance *coefficient + cost of prestation (based on type prestation depending from another custom field)

For example : 60*1,1 + 180 (for short event, near my city) or 170x2 + 600 (big event , far)
60 or 170 here are go and back so take distance calculated by Google maps, multiplied by 2.
