Projects
Chouette Market came to us with a Figma mockup and a unique idea: build a smart grocery store where you can plan meals by calories. As a leading Shopify app development company, we turned that concept into a custom-built experience. We integrated cart-based calorie tracking, meal plan logic, and subscription features everything powered by clean Liquid code. From design to functionality, this project showed why brands trust us for Shopify development services that go beyond just selling products.

Kawaii Slime Company didn’t want “off-the-shelf.” They needed custom features from top to bottom, and they picked the right Shopify web development company for the job (shout out C-Quark Co.) We built tiered gifting rules, a geolocation-based delivery date estimator, and a custom checkout all coded to scale. Every feature was built from scratch to match their brand, backend needs, and customer expectations. It’s one of those projects where development actually drove revenue because every click was crafted with purpose.

When Zing5G asked for a full subscription system for their internet plans, we got to work. As a Shopify app development company in the USA, we integrated Recharge for seamless trial-to-subscription flows. Customers get a free first month, then roll into monthly or annual billing with zero friction. The result they got? A clean setup that’s easy for customers to use and even easier for the Zing5G team to manage. It’s Shopify, scaled to handle service-based selling.

Entry Envy’s custom door sign business needed more than a simple cart. As one of the most agile Shopify app development companies, we helped them offer gift subscriptions that include custom recipient names and quarterly deliveries. We used Recharge for subscription logic and layered it with personalized gift options all tied together through custom code. We made it thoughtful, automated, and fully built for gifting at scale.

Lace & Lush wanted more from their checkout. Being their Shopify web development company, we used Shopify Plus checkout extensions to build upsell prompts, auto-apply gifts, and embed Trustpilot reviews directly into the flow. Customers now see tailored offers and confidence-boosting reviews while completing their purchase. This Shopify Plus build helped improve average order value and trust with no added friction. The checkout is fully branded, easy to manage, and built to support long-term growth.
