I have a public Shopify app with three plan options: $0, $99, and $299. These plans are displayed on the Shopify app listing and also on the website pricing page associated with the app listing.
Now, I’d like to onboard a client to a custom plan, where payments will be processed via PayPal. My plan is first to switch the client to the free plan, then onboard them to the custom plan with PayPal as the payment method.
Are there any restrictions from Shopify on doing this? Is this approach allowed?
Alternatively, would it be better to create a custom app specifically for onboarding clients to this custom plan?
