Custom Shopify apps
When Shopify needs to do more, we build the app.
BumpyLabs develops custom Shopify apps, embedded admin tools, extensions, and integrations around the specific workflows that create an advantage for your business.
Scope
What we help with
The work that typically sits inside this service. Every engagement is scoped to what your store actually needs.
- Private and custom Shopify apps
- Public Shopify app development
- Embedded admin apps
- Shopify Functions and checkout extensions, where supported by your plan and Shopify's platform capabilities
- App integrations and API development
- Merchant portals and operational dashboards
- Backend workflows, webhooks, and data synchronization
- App maintenance and iteration
Our approach
Build the part that only you need.
Most operational pain is specific: a pricing rule, an approval step, a fulfilment quirk, a data shape nobody else has. We scope the smallest reliable app that removes that pain, and put it where your team already works — inside the Shopify admin.
Native to the admin
Embedded apps that follow Shopify's interface patterns, so adoption does not need a training programme.
Event-driven, not polled
Webhooks and queued jobs with retries and idempotency, so a failed request is recoverable rather than silent.
Built to be handed over
Documented architecture, environments, and deploy path — an app you own, not one you depend on us to touch.
Deliverables
What’s included
What you receive from an engagement of this type. Exact deliverables are confirmed in the scope we agree together.
Technical discovery and architecture
Workflow mapping, API feasibility, and an architecture you can review before scope is fixed.
UX flows and interface implementation
Admin screens that follow Shopify's own interface patterns, so adoption needs no training.
Shopify API and webhook integrations
Event-driven connections with retries and idempotency, so a failed request stays recoverable.
Secure backend services
Narrow API scopes, credentials kept out of source control, and no sensitive data duplicated without reason.
Testing and deployment support
Coverage on the logic that carries risk, plus environments and a repeatable release path.
Handover documentation
Architecture, environments, and deploy steps written down — an app you own, not one you depend on us to touch.
App capabilities — including Shopify Functions and checkout extensibility — depend on your Shopify plan and Shopify's current platform rules. We confirm feasibility during discovery before scope is fixed.

FAQ
Shopify App Development FAQs
Direct answers to what teams ask before starting this kind of work.
A custom app is built for your store and installed directly, with no App Store listing or review process. A public app is distributed to other merchants and must meet Shopify's review requirements. Most operational work is a custom app; we build public apps when distribution is the goal.
Embedded apps need a backend service, which runs on infrastructure you own. We recommend a setup that matches your scale and internal capability, and hosting is billed to you directly by the provider rather than marked up through us.
Checkout customization is governed by Shopify and by your plan. Checkout UI extensions and Shopify Functions cover a defined set of use cases; others are not available regardless of budget. We check what your specific requirement needs against current platform capabilities during discovery.
We request the narrowest API scopes the app actually needs, keep credentials out of source control, and design so sensitive data is not duplicated without reason. Specific compliance obligations should be raised early so they shape the architecture.
Often, yes. We start with a code and infrastructure review to establish what exists, what is at risk, and what it would cost to stabilize. You get that assessment as a deliverable, whether or not you continue with the build.
