Hi, There. Thank you for reaching out to the Shopify Community.
I was able to find this IceCat Product Catalog App in the Shopify App Store, so it does look like Shopify is compatible with them. For Jeeves ERP, I was not able to find any information on our compatibility. I would suggest contacting them for more information, as they would have more knowledge on their compatibility with Shopify. Contact their team here.
