Vendasta's Marketplace allows you to market both your own custom products and vetted third party vendor products to your clients and prospects via the Business Center.
Your products, represented by the word Mine, are products or services that you provide directly to your clients or prospects. You determine and customize the pricing, the marketing content, and the copy.
Marketplace products are products or services that are provided by an approved third party vendor.
However, there is no discernible difference that your clients will see between products designed by yourself and a Marketplace product.
You can both create your own products or browse and enable Marketplace products via the Marketplace > Products tab in Partner Center.
