Who this is for

Is this you?

Problems it removes

What this fixes.

How we approach it

The order we do things in.

  1. Confirm what Shopify actually needsDecide whether the requirement needs an app, Function, extension, integration or an existing solution.
  2. Define permissions and dataMap merchant data, required API scopes, webhooks and the information the app needs to access.
  3. Build and test the app flowTest installation, authentication, merchant workflows and realistic store data before release.
  4. Prepare for distributionSet up billing, required webhooks, app behavior and submission requirements for the intended app type.
  5. Maintain supported versionsTrack Shopify API changes and update the app before deprecated versions become a production problem.

Questions

Shopify Apps: The Things People Ask

Do we need a Shopify app for this?
Not always. Some requirements are better handled with a Shopify Function, extension, existing app or normal store configuration. We check that before recommending a custom app.
What is the difference between a public and custom Shopify app?
A public app is designed for multiple merchants and Shopify App Store distribution. A custom app is built for the needs of a specific merchant or store.
Can you build an app that connects Shopify with our other systems?
Yes. Shopify can connect with ERP, CRM, WMS and other systems where suitable APIs are available. See API & System Integrations.
Can you take over an existing Shopify app?
Yes. We can review the current app, API versions, permissions and architecture, then determine what should be repaired or updated.
Do you maintain Shopify apps after launch?
Yes. Ongoing work can include API-version updates, fixes, monitoring and changes required as Shopify evolves.
