You pay separately, at cost
- Hosting for the app, paid to the hosting provider
- Any paid service or API the app calls, paid to that vendor
- Your Shopify plan, paid to Shopify
What you supply
- Staff or collaborator access to your Shopify store
- A written description of the feature and how your team will use it
- Accounts for any outside service the app connects to
What the price does not cover
- One private app for one store; a public App Store app is quoted separately
- The agreed features only; new features after handover are quoted
- Later changes Shopify makes to its APIs may need updates, which are not included
The rules that apply
- Shopify's custom distribution installs an app on a single store, on stores of one Plus organisation, or on development stores; it needs no Shopify approval and cannot charge merchants through Shopify's app billing. Shopify developer docs: App distribution
A cheaper way to do it
- Shopify Flow, Shopify's own app, is listed as free and automates order, inventory and marketing tasks in a visual editor, which can cover simpler features without a custom app. Shopify App Store: Shopify Flow
