An invoice is raised usually on the next working day after the session took place.
Once the invoice is raised, it will be sent by email to the member (just for your record).
At this point, this will trigger your direct debit and payment for that invoice will be taken approx 7-8 working days after session took place.
Therefore, when you get a notification that an invoice will be charged from your direct debit account, use that invoice number and search in your inbox for the copy of the invoice. You will then see what session is related to (look inside the description of the invoice).
