Custom Shopify apps for the workflow you can't buy

Private apps, public apps, integrations, and checkout extensions — built natively on Shopify by senior developers. When the App Store doesn't have it, we build it.

When you need a custom app

Off-the-shelf apps only go
so far.

Public apps are great until your process is too specific, too integrated, or too critical to depend on someone else's roadmap. That's when a custom or private app pays for itself.

The problem
  • No App Store app does exactly what you need
  • Stacking 10 apps that slow your store and conflict
  • Paying rising monthly fees for apps you've outgrown
  • A core workflow trapped in spreadsheets or manual work
  • Integrations between Shopify and your other systems breaking
How we solve it
  • A private app built precisely for your workflow
  • One purpose-built app instead of a fragile app stack
  • Own the code — no per-seat fees you can't control
  • Automate the manual process that's eating your team's time
  • Reliable, maintained integrations with your ERP, CRM, or POS

How it works

The build, section by
section.

Phase · Scope

We define exactly what the app must do.

Before a line of code, we map the workflow, the data, and the edge cases. A tight spec means a predictable build and an app that fits your process precisely.

  • Workflow & data mapping
  • Edge-case definition
  • API & integration plan
  • Fixed scope & timeline

Questions

Frequently asked.

A private (custom) app is built for your store alone and isn't listed on the App Store — ideal for a specific internal workflow. A public app is distributed through the Shopify App Store to many merchants and must pass Shopify's review. We build both.

Yes. Integrations are a core part of what we do — we connect Shopify to systems like ERPs, CRMs, POS, and 3PLs with reliable, maintained syncs rather than fragile one-off scripts.

Yes. We build with Shopify's modern extensibility — Functions for discounts and shipping logic, and checkout UI extensions on Plus — so your customizations are upgrade-safe.

Built correctly, no. We build lean and native, and a single purpose-built app often replaces several heavy App Store apps, improving performance overall.

Yes. Shopify's platform evolves, so we offer ongoing maintenance — bug fixes, version upkeep, and iterations — as a project add-on or a Care Retainer.

Yes. We work white-label for agencies who need senior Shopify app development delivered behind their brand.
