Direct debit payment

When signing up to Zwift as a paying member will future direct debits be taken on the day you signed up to Zwift eg if I buy the membership on the 1st of the month will the payment come out on the 1st of every month or next available working day from then on? Thank you in advance

Billing starts the first day after your free trial, or if you do not have a free trial, the first day you sign up for a membership. That will be your billing date.
