Custom Shopify App Development Services

Shopify Development Scalable Secure Performance Reliable Long-Term Support

Shopify Development

We build custom Shopify apps for merchants whose workflow has outgrown what the App Store sells - stores that need Shopify to talk to an ERP, to price differently per customer, or to run a process no public app models.

The apps are embedded in the Shopify admin and built on Shopify's current APIs, so they behave like part of the platform rather than a bolt-on.

When a custom app is the right call

A public app is almost always cheaper. It is worth building your own when the alternative is bending the business around software that nearly fits.

Worth building

The cases where a custom app pays for itself:

Shopify has to exchange products, stock, prices, orders or invoices with an ERP or back-office system
B2B rules the platform does not cover - customer-specific pricing, approvals, purchase limits, sales-rep ordering, net terms
A repetitive process worth automating: order routing, product sync, document generation, returns, data validation
An internal tool your team needs that no customer ever sees
Checkout, discount or shipping logic that belongs in Shopify Functions

Not worth building

We will say so if you land here:

A public app already does it, and the compromise is cosmetic
The requirement is really a theme change
The process is still changing week to week - automate it once it settles

What you get

An embedded app in the Shopify admin, so your team never leaves the platform they already use
Admin extensions where the work belongs on the order or product screen itself
Shopify Functions for discount, shipping, payment and validation logic
Webhook-driven automation that reacts to events instead of polling on a timer
The integrations behind it, and dashboards for the numbers Shopify's own reports do not answer
The repository, the hosting and the service accounts - in your name, documented

What we connect it to

Most of the work in a custom app is not the Shopify half; it is everything the store has to agree with. We integrate with ERP, CRM, PIM and warehouse systems, accounting software, shipping carriers, marketing platforms, and with in-house systems over their own APIs.

How we build it

We start from the workflow, not the feature list - what happens today, where it breaks, what a result looks like
The architecture is agreed before any code: how the app talks to Shopify and to everything else
Built on Shopify's current APIs and recommended practices, so a platform update is not a rewrite
Secure authentication and access control, tested for behaviour and integration reliability before it goes live
Deployed, monitored, and maintained as Shopify changes

Frequently Asked Questions About Shopify App Development

When should I build a custom Shopify app instead of installing an existing app?

A custom app is the better choice when existing apps cannot support your workflows, require extensive compromises, introduce unnecessary complexity, or cannot integrate with your existing systems.

Can a Shopify app integrate with our ERP or CRM?

Yes. Custom Shopify apps can securely integrate with ERP, CRM, PIM, WMS, accounting platforms, and other third-party or proprietary systems through APIs and middleware.

Can existing Shopify apps be extended?

In some cases, yes. However, if an existing app does not expose the necessary extension points or APIs, developing a dedicated custom app may provide a more reliable and maintainable solution.

Are custom Shopify apps secure?

When developed using Shopify's recommended authentication methods, secure API practices, and appropriate access controls, custom apps can provide a high level of security while protecting both business and customer data.

Who owns the app after launch?

You do - the code, the repository and the service accounts. Emporica provides ongoing support and maintenance to keep the app compatible with Shopify's platform updates, but your business is never dependent on us to keep it running.
