Hi @TerryHibbert.
We may have already chatted via email, but what you’re after is possible with Foxy using our Purchase Order option. Customers can add products to cart as normal and then checkout without having to provide payment info (or even a PO number). Information is then sent to store owners via email.
Also, the entire product catalog can be managed entirely in Webflow. No back and forth between Shopify and Webflow. 
Feel free to message me for more info. We’ll get you taken care of.
Thanks,
Josh
