Membership Fees
Membership fees are charged separately to invoices for usage. Membership fees will be charged monthly or annually, depending on your plan, and will renew on the day that they're due.
For example:
If you signed up under a plan on the 23rd of a month, and your membership fee is charged monthly, your membership fee will be charged on every 23rd of the month going forward.
If you signed up under a plan on the 2nd of January, and your membership fee is charged annually, then your membership fee will be charged on the 2nd of January every year going forward.
Note: Not all plans include membership fees. You can check out which plans have membership fees, and if applicable, whether they're charged monthly or annually here.
