FAQs
What sets apart the Enterprise and Pro plans?
The primary distinction between the Pro and Enterprise plans lies in the level of security and support provided.
ProtoPie Enterprise offers two tiers:
ProtoPie Enterprise On-Premises: Utilize your organization's server and physical hardware.
ProtoPie Enterprise Cloud: Access a secure space on AWS exclusively for your organization.
For a detailed breakdown of features, please refer to our pricing comparison chart. Contact us for more detailed information.
How do I upgrade from Basic to Pro?
To upgrade from the Basic to the Pro plan, follow these simple steps:
Visit ProtoPie Cloud.
Click on your account name in the top right corner and select Billing.
On the Manage Billing page, locate the Basic Plan section.
Click the "Upgrade to Pro" button.
Once the upgrade is complete, please contact us for a prorated refund for the unused portion of your Basic plan.
How do I add the Connect add-on to my Basic plan?
To add the Connect add-on to your existing Basic plan, please visit the Manage Billing section on ProtoPie Cloud and select the add-on for purchase. If you are new and planning to subscribe to the Basic plan, you can include the Connect add-on during your initial subscription process.
How do I add the Connect add-on to my Pro plan?
You can choose the Connect add-on directly while subscribing to the Pro plan. If you decide to add it later, simply visit the Manage Billing page on ProtoPie Cloud to purchase the add-on.
If your Pro plan subscription was started before May 9, 2024, and you wish to remove the Connect add-on, follow these steps.
How is the Connect add-on billed?
If you're on the Pro plan, you must purchase the Connect add-on for each individual editor from your team, not for the team as a whole.
If your team consists of 5 editors, you must purchase the add-on for each editor; it cannot be applied to just one or a few editors.
The add-on is billed according to your subscription plan: monthly if you're on a monthly plan and annually if you're on an annual plan (applicable to both Basic and Pro plans).
What payment options are available?
We offer various payment methods for our paid plans.
For the Basic and Pro plans, you can pay with a Credit card or via PayPal.
For the Enterprise plan, you can only pay through wire transfers. Contact us if you and your organization are interested in the Enterprise plan.

How do I become an official ProtoPie reseller?
