Product Cross-Selling For WHMCS will let you suggest hand-picked sets of additional products, addons and services to your audience depending on the items they already have in a shopping cart. The module will allow your customers to order from the list of personalized recommendations, and even choose between the most attractive discount opportunities once integrated with Discount Center For WHMCS.

You will be empowered to define precise cross-selling rules upon which your clients will be offered complementary products and addons, plus flexibly manage the selection of related and recommended items. The number-one benefit our module comes with is the possibility to tailor suggested products down to the tiniest detail - from their unique description in multiple language versions, through an individual image and background, to labels freely customizable in text and colors. The scope of your cross-selling capabilities will extend even further to defining the exact number of complementary items required in the cart for the order to be placed.

Equipped with Product Cross-Selling For WHMCS, you can not only advertise the individual, most profit-making items, but also boost the appeal of your offer in general. Order the module today to drum up your sales in an instant, and let your audience feel perfectly catered for!
