We sell custom silver products (belt buckles, rings, etc). We have a vendor who makes custom products to our customers exact specifications. When a customer places an order they tell us what text and images they want on their product. We then communicate with the vendor to design a digital proof for the customer. I would like to use an app for our vendor to communicate, send images back and forth etc. with us regarding orders. OR, a way to allow the vendor to login to our Order dashboard, but hide the order details (shipping details and payment amount) from the vendor.
