What's the difference between a public and private Shopify app?

Public apps are listed on the Shopify App Store for any merchant to install; private apps are built for a single store's specific needs.

How long does Shopify's app review process take?

Review timelines vary, but we prepare apps to meet Shopify’s technical and design requirements upfront to avoid review delays.

Can you take over an app another agency built?

Yes — we start with a codebase audit before extending or fixing an existing app.

Do you build apps that connect to systems outside Shopify?

Yes, including ERPs, CRMs, and custom internal tools via API.

Will the app still work after Shopify updates its platform?

We track Shopify's API changelog and update apps proactively rather than waiting for something to break.

Clean, tested, production-ready code.

Engagement Models

Fixed-Price Project

A clearly scoped project with a defined deliverable, timeline, and budget — best when requirements are well understood upfront.

Dedicated Team

Ongoing embedded development capacity that works as an extension of your team — best for long-term product work or evolving roadmaps.

Hourly / Time & Materials

Flexible, pay-for-what-you-use engagement — best for smaller tasks, ongoing support, or work where scope may shift.

Project Timeline

A focused private app for a single workflow typically takes 3–5 weeks; a full public app intended for the App Store typically takes 8–12 weeks including review preparation.
