Shopify apps
for real stores.

Custom Shopify app development for merchants and teams that have outgrown theme hacks, spreadsheet ops and fragile app stacks.

When to call us

When commerce logic should not live in a workaround.

Shopify is strongest when custom logic respects the platform. We build apps and integrations that work with Shopify, not around it.

Custom app

No App Store product fits the workflow.

We build private and custom apps for merchant-specific operations, admin workflows and data rules.

Integration

Shopify has to talk to the rest of the business.

ERP, PIM, CRM, warehouse, subscription and finance integrations with webhooks and resilient retries.

Plus

Checkout or B2B needs platform-grade work.

Checkout Extensibility, Shopify Functions and Plus workflows planned around platform constraints.

Process
01

Audit the workflow.

We identify what belongs in Shopify, what belongs outside and where existing apps create operational debt.

02

Build with platform constraints.

Rate limits, webhooks, app review, permissions and checkout rules are design inputs, not late-stage surprises.

03

Hand over operations.

You get app code, deployment, monitoring, runbooks and a clear ownership model.

FAQ

Shopify questions.

Do you build public Shopify apps?
Yes, when the product requires it. We also build custom apps for single merchants and Shopify Plus teams.
Can you replace an existing Shopify app stack?
Often. We start by mapping which apps are essential, which are operational debt and which logic belongs in a custom app.
Do you handle Checkout Extensibility?
Yes. We plan checkout work around Shopify's current extension and Functions model.
