Hi, I am working on an app which connects my SAAS tool where we plan merchant’s stock situation. For time being, I am not going to charge merchants and app will be free for some months. I also chose Managed Pricing option while submitting my listing in Shopify.
In this case, do I need to integrate with Billing API? I am happy to even charge for free for sometime, since getting customers to use the tool is important for us. I am looking for ways to get my app approved without needing to use Billing API.
