You can switch a development store to a paid plan but still be the store’s owner. For example, you might want to do this if you need to test a feature not available in development stores.
To switch to a paid plan, you can follow these steps:
Log in to your Partner Dashboard and click Stores.
Find the store you want to transfer, and then click Log in.
From the Shopify admin, click Settings > Users and permissions.
In the Plan Details section, click Compare plans.
Click Choose this plan and select one of the available plans.
Select a billing cycle and review the description of the credit card charges that you agree to.
Select a payment method, and then enter your payment method information.
Click Start plan.
There are some things to consider when you retain store ownership:
If you switch a development store to a paid plan, you can’t earn a recurring commission on that store. To comply with the Partner Program Agreement, you need tocontact Partner Support to have the commission removed from the store.
If you switch a development store to a paid plan, you can’t transfer it using the Partner Dashboard. To achieve that, you must transfer ownership and remove your payment details manually.
I hope that helps. Let me know if you have any further questions.
