Our billing model is a monthly subscription. Each price listed is a monthly fee which can be upgraded or downgraded at any time. Payments are pro-rata for upgrades, i.e. you will pay for the rest of the month and the full amount next month.
Packages are for account hosting, each account is considered an account no matter what their purpose is.
If you have a standard 2-account package, you get 2 accounts which can be used to host 1 lead/copy from and 1 follower/send to account.
If you have a plus account package, you get 5 accounts. You can use your accounts in any way you like, with 2 leads/copy from accounts and 3 followers/send to accounts or 1 lead/copy from and 4 followers/send to accounts, it does not matter.
