Shopify Development Agency
Shopify development for stores with complex operations.
Custom apps, theme functionality, checkout and fulfillment logic, integrations, and operational tooling for merchants who have outgrown off-the-shelf apps.
Free 20-minute technical triage. Written technical audits start at €500.
What you get first
A clear technical read on the problem.
Before proposing a build, we establish what is failing, what Shopify can handle natively, and where custom engineering is justified.
- 01
- DiagnosisThe actual constraint, dependencies, and technical risk.
- 02
- RecommendationFix, audit, integration, or custom build — with the reasoning.
- 03
- Next stepA practical scope and price range before paid implementation.

Selected technical work
Inspect the work before trusting the pitch.
A Buy-Now-Ship-Later Shopify app, end to end
Designing deferred shipping, paid order holds, and self-service order consolidation as a production Shopify app.
View the exampleConstraint
Customers buy across releases but want one later shipment.
System
Paid order holds, customer-owned release state, and fulfillment controls.
Operational result
A self-service workflow that replaces repetitive support handling.
Technical deep dives
Delivery Customization Functions for custom shipping
When shipping-method logic belongs in a Shopify Function — and when it needs backend-owned order state.
ReliabilityRetry-safe Shopify webhook pipelines in Rails
Making webhook processing idempotent and replay-safe so orders are never lost or double-counted.
OperationsOrder consolidation and ship-later workflows
Letting customers buy across drops and combine paid orders into one shipment without manual support work.
Why this studio
Specialist, senior, and accountable.
Production experience
We build and operate a live Shopify app, so webhooks, rate limits, and partial failures are operating realities, not theory.
Senior technical delivery
The people scoping the work are the people designing and building it. There is no hand-off to a junior delivery layer.
Narrow specialization
We focus on custom Shopify functionality and complex operations rather than trying to be a full-service marketing agency.
European working rhythm
Based in the Netherlands, working across Europe and beyond with direct, asynchronous communication.
Process
Four phases from diagnosis to a stable launch.
- 01
Diagnose
We review the store, stack, code, and operational constraint before proposing a build.
- 02
Plan
You get a concrete scope, delivery sequence, risks, and a fixed or ranged price.
- 03
Build and verify
We develop in staging and test real Shopify failure modes, not only the happy path.
- 04
Launch and support
We ship carefully, monitor the release, and stay available for the next iteration.
Pricing
Clear starting points. Scope sets the final number.
Every engagement starts with context and a written scope. The free fit call is for qualification; deeper diagnosis begins with the paid audit.
