Backupify/Datto SaaS Protection for Google Apps offers 2 methods to pay for your account. Those methods are for monthly or annual payments.
If you activate your account with a credit card directly from our site then your account will be set up on a monthly subscription service. To activate your account on a monthly basis, simply click the 'activate account' link in the upper right corner of account to start the process of entering in your credit card.
You can pay for your account on annual basis, however we currently only offer annual invoicing to accounts that are more than $360.00 a year. Also, annual invoices need to be manually generated for you and cannot be directly activated from the site. To activate your account on an annual invoice, please contact email@example.com and a sales representative can get you set up with the invoice. Payment options for annual invoices can be done via a credit card, check, or ACH.
