Managing Existing Payments
If you need to manage your existing payments, either go directly to https://service.ottertune.com/manage-subscriptions.
Or navigate to this page in the browser by selecting 'Manage Subscription' from your profile settings menu.
If you would like to upgrade to an enterprise plan, please reach out on the pricing page. If you would like to increase the amount of databases under a standard plan, you can manage your subscription directly.
All changes will be prorated based on when in the billing cycle you upgrade your plan.
