Advanced Development

Custom Build —
Apps & Features

The subscription block we built for a US creatine brand — when their app couldn't deliver the UX they needed — helped them reach $1.35M/month. When apps hit their ceiling, we build past it. This is that service.

What We Build

Beyond what any app
can give you.

📱

Private Shopify Apps

Custom apps built for your store only — not limited by what's available in the App Store. Your logic, your rules, your UX.

🛒

Cart Transform API

Custom bundle logic, conditional discounts, free gift triggers, and cart rules that no off-the-shelf app can replicate exactly.

💳

Checkout Extensions

Custom upsell widgets, delivery date pickers, loyalty point displays, and branded UI built directly into Shopify's checkout — no third-party redirect.

🔄

Custom Subscription Blocks

When ReCharge or Skio can't deliver the subscription UX your brand needs, we build the entire block in Liquid and JavaScript — matched to your design perfectly.

📦

Bundle Builders

Custom product bundling with dynamic pricing, visual selection UI, and inventory rules — built to work exactly the way your products and pricing need.

🔗

Third-Party Connections

Custom API connections between Shopify and any external system — your own database, a custom pricing engine, a loyalty platform — whatever the integration requires.

How It Works

Scoped carefully,
built to last.

01

Requirements Discovery

We dig into exactly what you need the build to do — not just the surface request, but the underlying business logic, edge cases, and future scalability.

02

Technical Architecture

We design the solution: data model, APIs used, Shopify extension points, and maintenance plan. Presented for your team to review before any code is written.

03

Iterative Build

Built in stages with regular demos. You see working functionality throughout — not just at the end. Feedback incorporated in each sprint.

04

Launch, Document & Support

Launched, fully documented, and handed over with a clear maintenance guide. We offer ongoing retainer support for teams that need continued development.
