Custom Shopify apps

When the App Store doesn't have it.

Custom Shopify app development from Bentonville, Arkansas: private apps, Shopify Functions, checkout extensions, and integrations built on Shopify's current APIs — and owned by you.

App services

Shopify Functions & checkout

Custom discount logic, shipping and payment rules, cart validation, and checkout UI extensions that run natively inside Shopify.

  • Tiered, bundle, and B2B pricing rules
  • Delivery and payment customizations
  • Checkout upsells, fields, and validation

B2B & trade portals

Extend Shopify B2B with quote requests, designer and trade programs, net-terms onboarding, and catalog logic the native settings don't cover.

  • Quote and sample request flows
  • Company onboarding and approvals
  • Custom price lists and catalogs

Integrations

Connect Shopify to the systems you already run: ERPs, PIMs, warehouses, product feeds, and marketing platforms.

  • Google Merchant Center & Feedonomics
  • NetSuite, QuickBooks, and 3PL syncs
  • Klaviyo, CRM, and subscription data

Internal tools & AI

Admin extensions, merchandising tools, and AI-assisted workflows — product copy, image handling, support triage — built into the Shopify admin your team already uses.

  • Admin UI extensions
  • Bulk operations and automations
  • AI copy, tagging, and search
How we build

Modern Shopify stack. Your code, your repo.

How an app project runs from first call to hand-off.

  1. Step #1

    Scope

    We write down exactly what the app does, which APIs it touches, and what “done” means. Fixed price, no change-order games.

  2. Step #2

    Build

    Shopify CLI, Remix app templates, Admin GraphQL, Functions, and UI extensions. Nothing deprecated, nothing hacky.

  3. Step #3

    Test

    Development stores, real data, edge cases. We test checkout flows the way customers actually use them.

  4. Step #4

    Hand off

    Source in your GitHub, documentation, and hosting on your infrastructure or ours. You own it either way.

FAQ

Custom app questions.

What people ask before an app project.

When does a store need a custom Shopify app?

When an off-the-shelf app can't do what the business needs, does it badly, or costs more every month than a custom build would over a year. Common cases: unique discount or shipping logic, B2B quoting, integrations with an ERP or warehouse, custom checkout experiences, and internal tools for merchandising or operations.

What are Shopify Functions?

Shopify Functions let developers customize Shopify's backend logic — discounts, shipping rates, payment methods, cart validation, and more — with code that runs inside Shopify's infrastructure. They replace older Script Editor approaches and are the modern way to implement custom commerce rules on Shopify and Shopify Plus.

Can you build a B2B portal on Shopify?

Yes. We extend Shopify's native B2B with custom company onboarding, quote requests, designer and trade portals, net terms workflows, and catalog logic that native settings alone don't cover.

Do you build public apps for the Shopify App Store?

Our focus is custom apps built for one merchant or brand. We can advise on and build public apps, but most of our app work is private: tailored to a single store's needs and owned by the merchant.

Which stack do you use for Shopify apps?

Shopify's current tooling: Shopify CLI, Remix-based app templates, the Admin GraphQL API, Shopify Functions, and checkout UI extensions. Hosted on your infrastructure or ours, with the source code owned by you.

Have a problem the App Store can't solve?

Describe what you're trying to do in plain language. We'll tell you whether it needs a custom app, a Function, or just a better setting.
