Does Shopify prevent the creation of stores selling recreational shooting products?

Good day,

I am working with a client where there is a potential to replace Woocommerce and Foo Sales because they are not working properly together.

I mentioned my success as a Shopify Partner and the owner said “good luck, Shopify will not work with us.” When I queried for more information he indicated that Shopify refused to work with recreational shooting supply stores.

This potential customer sells gunsmithing services, firearms parts, recreational shooting components such as belts, holsters and magazine pouches as well as some small amount of reloading components and ammunition. They also from time to time have used non-restricted firearms for sale. They do not sell new firearms at all, but do hold proper Canadian licensing to do so.

Can someone please point me to the documentation, if any, that explains if and why Shopify would not allow the creation of an online and POS solution for this customer?

Thank you kindly

Ross Chevalier
