User balance and prepaid payment

Hi,
I'm using version 2.7.6 and I want to use the user balance feature. In help documentation it mention there is a prepraid payement plugin to use, I didn't see where I can found it.

Some advice will be helpull to use this feature. Regards.

Hi Florian,
You can add the Balance to users through tool: Manage Balances at Backend of OS Services Booking extension.

Hi Dam,
Thanks for your message.
Actually I did add the balance to user. What I don't found is how the front end customer can use this balance when he pays.
Is there a specific payement plugin to enable ?
