Do you offer an annual subscription/a one-time payment?
No, we have not supported an annual subscription or a one-time payment. Currently, we are supporting monthly payment only and Shopify is the one in charge of the payment process, not us.
Thus, our plan is based on the customer’s current total products, which you may monitor via this Shopify link: https://yourstore.myshopify.com/admin/products/count.json (yourstore is your real Shopify store name)
Whenever you upload more products, you will be notified to upgrade your plan later on.
