Insights & assistance can I get some advice?

Hello I am new here and very grateful. I have a few questions and was looking for some guidance. If this is not the right thread or forum to ask of this, please let me know and I will remove the post as I don’t want to offend or break any rules.

Our developers are working on re-tooling one of our platforms we use for very large non-Shopify stores for the App Marketplace.

We want to be very thoughtful about what features are needed for basically back office, post-click operations such as shipping, orders management, inventory, and warehouses, just to name a few. Would any store owners new or experienced be willing to allow me to ask some questions strictly for market research?

As a side note, I am passionate about CrossFit and am helping my local box build a Shopify online store where they can sell CrossFit clothing and other swag so the information would be very helpful as I am new to this side of the ecommerce side of things.

Looking forward to feedback and guidance-

Be safe and well,

Gloria
