The challenge

Flex Moves was making sales, but the team knew the store had more potential than its revenue showed. Competition in e-commerce has never been higher, and standing out among so many stores is a real challenge. The cheaper opportunity was already in the order stream: existing customers who had just paid and were open to hearing about one more product.

The task was specific. Pitch new and unique products to existing customers at the moment of purchase, using a seamless one-click post purchase upsell that did not interrupt checkout or put the original order at risk. Flex Moves needed an app that could do this on Shopify without custom development, and ideally one that also covered offers before checkout and on the thank you page, so a single setup would work across the whole buying journey.

The solution

Flex Moves chose Cart X and set up all three placements: in-cart offers before checkout, one-click post purchase upsells, and thank you page offers.

Cart X was our go to option due to the affordable pricing plan and how easy it was to set up.

The post-purchase placement did the heavy lifting. Because Cart X is built on Shopify Checkout Extensibility, the offer appears after payment is confirmed and before the thank you page, and the shopper accepts it with a single click using the payment method already on file. The original order is never touched, so there is no conversion risk and no card details to re-enter. A shopper who is not interested simply declines and continues to the order confirmation.

Setup took little time, and the store began to see steady growth in average order value soon after launch.

The results

Flex Moves generated $10,853 in total additional revenue through Cart X. The post-purchase placement accounted for $10,126 of that across 654 one-click upsell orders, which is roughly 93% of all upsell revenue and an average upsell value of about $15 per accepted offer.

  • Post-purchase orders: 654
  • Post-purchase revenue: $10,126
  • Total revenue generated: $10,853
  • Average upsell value: $15

Every dollar of it came from customers Flex Moves had already acquired. Nothing changed about the products it sells or the traffic it buys; the store simply started showing existing customers the right offer at the moment they were most likely to accept it.

Really good app to prompt customers to add optional parts to their cart. It saves them receiving a product and then being disappointed they didn't realise they needed to order the other bit.
