What a custom Shopify app is for

Shopify handles the common case well. The trouble starts where your business stops being the common case — pricing that depends on the customer, fulfilment that runs through your own warehouse, a supplier feed that has to stay in step, an internal system that needs to know about an order the moment it lands.

That gap is what a custom app closes. It is not a redesign of your store; it is a piece of software that makes the platform behave the way your operation already works.

If the store itself is the problem rather than the app, start with ecommerce development. If what the app has to do is read language — supplier emails, support tickets, product data — that is AI inside your existing system.

What we build

Three kinds of work, and which one you need

One store, one specific problem.

Private apps

Built for your store alone and installed only there. The right answer for most businesses: no App Store review, no multi-tenant complexity, no billing system to run.

You want to sell it to other merchants.

Public App Store apps

Listed publicly, so it has to pass Shopify's review, serve many merchants at once, and carry billing, onboarding and support. A product, not a project.

Two systems that disagree with each other.

Integrations

Shopify talking to an ERP, accounting package, warehouse or 3PL, CRM or supplier feed — so nobody is re-typing an order into a second system.

The questions that decide this one

What is the difference between a private and a public Shopify app?

A private (custom) app is built for one store and installed only on that store, which is what most businesses need. A public app is listed on the Shopify App Store for anyone to install, which means Shopify reviews it, it has to handle many merchants at once, and it needs billing and support around it. We build both, but we will tell you honestly which one your situation calls for.

Do I need a custom app, or is there one on the App Store already?

Usually there is something close. We will say so if there is — paying for an existing app is cheaper than paying us to rebuild it. Custom work earns its cost when the requirement is specific to how your business runs: your pricing rules, your fulfilment process, your supplier feed, an internal system that has to stay in step with the store.

Can you connect Shopify to the systems we already use?

Yes. That is the most common reason we get called in — an ERP, an accounting package, a warehouse or 3PL, a CRM, a supplier feed. The work is usually an app plus a sync process, so the two systems agree without anyone re-typing anything.

Who owns the app when it is finished?

The Shopify Partner account and the app listing are in your name, with full access handed over at launch. For a private app built for your store the source code is normally yours too, in a repository you control. The contract states it before work starts, so there is nothing to argue about later.

Not sure which of these you need?

Describe what Shopify is not doing for you, in plain language. If an app on the App Store already solves it, we will tell you that instead.
