Upgrading your account is easy, and can be managed from anywhere in PlayBooks.
After logging in to PlayBooks, click on the change plan icon from the top-right of the app. This icon displays the current plan you are on, in this case 'Collaborate Plan'.
Next, you'll see the account management modal. From here you can:
See which plan you are on.
Update your Billing information
Update your Payment method
Download your invoices under Billing History
If you don't have a payment method on file, you'll need to add one first. Click Payment Methods and enter your card information.
To change your plan, click on the plan name and then click Edit Subscription.
From here you can select your new subscription by clicking the drop-down menu.
Once selected, click 'Update Subscription'.
And you're all set!
