From customer toadvocate.


Kwik rewards customers for what they already do: buy, come back and bring friends along. Points, cashback, commissions and prize draws, in one platform. We build the Shopify app that puts that platform in any store, from the widget on the homepage to redeeming points at checkout.
What we built
This time not a store for one brand, but a public app in the Shopify App Store, built to run in many shops at once.
One app for every store
Install from the App Store, connect to Kwik and the rewards programme is live. Approved by Shopify's review team, with billing and privacy rules built in from day one.
Rewards inside the store itself
Ready-made blocks for any Shopify theme: a widget that travels with the customer, points and prize draws on the product page, and a personal sharing link for advocates.
Redeeming points at checkout
Customers log in to Kwik while checking out and turn points straight into a discount. Smart rules decide which discounts may combine, so promotions never stack when they should not.
An engine that keeps track of everything
Every order, sign-up and refund goes through a queue built to take a knock: duplicate notifications are filtered out and failed jobs retried automatically. The Kwik team watches along live in its own dashboard.

From bespoke work to a product
An app for one store is bespoke work. An app running in many stores at once is a product, and that calls for different decisions. Every setting that is obvious for a single brand has to become configurable. And a bug that shows up one time in a thousand shows up daily across thousands of orders.
So Kwik 2.0 got a new foundation: a queue per store, duplicate webhooks filtered out automatically, and administration that simply lives in the Shopify admin. The Shopify review team's requirements were not a hurdle at the end but the starting point.
A good rewards programme feels obvious: the points add up, the discounts combine cleanly, and the thank-you page knows exactly what you earned.
Where it stands today
Kwik 2.0 is live in the Shopify App Store, alongside the first generation we built for Kwik in 2023. Stores move across one by one and their historical data comes with them, without their customers noticing a thing.
And we keep building: prize draws alongside the points programme, smarter referral detection, and copy that brands can adjust down to the word. The score in the App Store so far: 5.0.
