Turning Post-Purchase Into a Performance Channel: How 5 Star Nutrition and incQX Reimagined the Checkout Experience
5 Star Nutrition has always known its edge: expert guidance. Whether customers walk into a store or order online, they expect advice that feels personal and product recommendations that work. But in the online world, that kind of consultative selling often stops at checkout.
Together with IncQX, 5 Star Nutrition flipped that assumption and turned post-purchase into a high-performing touchpoint.
Building a Smarter Checkout
Rather than treat checkout as the end of the sales funnel, IncQX helped 5 Star Nutrition transform it into a new opportunity to engage customers and drive growth.
We worked together to implement and extend a post-purchase experience powered by the AfterSell plugin on Shopify. Our custom integration gave customers the ability to add suggested discounted items to their order immediately after checkout—boosting value without interrupting the customer checkout flow.
But integrating this into 5 Star’s existing systems wasn’t as simple as flipping a switch. The brand’s technology stack includes NewStore and NetSuite, which operate differently than Shopify when it comes to order management and timing. Bridging those differences required careful orchestration of order events and data flows, especially in a moment as time-sensitive as post-purchase.
Solving the System Gap
Shopify enables updates to an order after it’s placed; NewStore processes orders as finalized upon creation. Our team designed a solution that respected both platforms’ strengths, capturing order changes post checkout and ensuring clean, accurate downstream fulfillment.
The outcome was a harmonized flow where the customer’s final order—post-updates—was captured seamlessly and sent for fulfillment only once complete. No missed items. No fulfillment errors. Just a smarter, more valuable checkout experience.
The result: a frictionless, branded post-purchase experience that boosted revenue and maintained consistency across all systems.
The Business Impact
Just 1 week post-implementation, 5 Star Nutrition began to see measurable improvements in sales:
12 extra items added to purchases per week
Estimated $20K of incremental revenue per year
What mattered most was that the experience felt authentic to the 5 Star brand. It gave customers more value without adding friction and reinforced the brand’s commitment to expert guidance at every stage of the journey.
