Statistics and research show that upselling has led to an increase in 25 to 30 % of the store revenue. Creating eye-catching, product related and interesting offers easily leads your customers to buy more and ultimately increases sales. Looking at this data, Lucent Innovation has come up with an application Simply Cartbooster. This application allows you to create upsell rules and conditions. These customized upsell rules, will pop up after the confirmation of payment i.e., on the payment acknowledgement page. This application will create various discount product offers and sales offers, that will lead the customers to buy more from the store when interested upsell popups are visible.
