The date that you created your first Vault account becomes your monthly billing date. Any accounts that you add after this date, and before the next billing date, will be charged on a ’part month’ basis.
For example, if you subscribed to the ‘standard’ plan, which costs £8 per user per month, and create another user account 10 days into your 30 day billing period, you will be charged for the remaining 20 days in that period. We calculate this amount using the per-day cost of the account, which in this case would be £8 / 30. We will make a one-time charge of £5.33 +VAT (£8 / 30 * 20 days) to your Direct Debit subscription.
