Hello wirecreative,
Thank you for interesting in our EShop Shopping Cart extension and submitting the question here.
1. Yes, EShop support the catalog mode which does not have any ecommerce features. You just need to enable catalog mode from the configuration of EShop.
2. Then you can also enable the Quote mode to allow visitors to add the products to the quote and submit it to admin's store via a quote form with just some fields: name, email, telephone, company, message.
So I am pretty sure that EShop meets that your requirement.
If you have any other questions, don't hesitate to let me know.
Sincerely, Giang
