Hello, can you please explain how to switch an account from monthly billing to annual billing?  When I click "Change" under Manage Subscriptions the only option is to cancel the subscription.  Please describe the best procedure to change to an annual plan.  Thanks.

Subscription plans cannot be changed directly. You will need to order a new annual plan(s) and then cancel your old monthly plan(s). Your data is not associated with a plan, so changing a service plan will not affect your files. (Just make sure you have enough storage space and download bytes). 

Some users may have multiple monthly service plans; in this case, you need to do so for each monthly plan.

If you ordered an annual plan, please don't cancel it and order it again. You just need to make a payment of the annual amount. To find your annual service price, please log on to www.drivehq.com, go to My Account page, then click Transaction History -> View Order List. If you have multiple (active) orders, you need to add the total amount.
