Hello!
We’re working on our first Shopify project and it we’ll be a mobile App.
So I have a few questions:

  • If a product in the cart can’t be shipped to a selected region, can we block the cart or remove the product at checkout?
    Or is it possible to display an alert?
  • Can we adjust the cart’s total price to offer a discount for specific payment methods?
    Alternatively, could be an idea to dynamically add or remove a coupon based on a preselected condition ((es. I ask before the payment method I’ll use))?
    But built-in option for this would be ideal.
  • Is it possible to create multiple catalogues or set different prices for a product based on customer roles (like VIP customers), without using the B2B option?
    I found plugins like Wholesale Pricing Discount https://apps.shopify.com/wholesale-pricing-discount?utm_campaign=Guru+Ask&utm_medium=Forum&utm_source=social.

Also, has anyone had experience integrating Microsoft NAV ERP with Shopify?

Thanks for your help and kind regards,
Davide
