You have two different ways to pay.
Each bill is debited from your alwaysdata prepaid account with the due amount. You have to refill this prepaid account to cover your charges.
Payments can be honored using:
EU check: send your check to alwaysdata - 91 rue du Faubourg Saint Honoré, 75008 Paris, FRANCE (to : alwaysdata). Also indicate your client number on the back of your ckeck;
Wire transfer : to be done on our bank account by putting your client number in the comments of the transfer. Bank transfer account feeds will appear in your interface as soon as they are taken into account by our team.
It's the simplest method. You enter your bank details in your administration interface, section "Billing" > "Payment methods". Your bank account will then be automatically debited of the due amount. You don't have to take care of paid each month your alwaysdata hosting.
When you activate the direct debit on your bank account, we suggest you to give to your bank a debit authorization.
