Book a free consultation and discover how a custom Shopify app can automate your workflows, unlock new revenue streams, and give your store capabilities that no off-the-shelf app can match.
A custom Shopify app is a bespoke application built specifically for your Shopify store, using Shopify's official APIs to add functionality that doesn't exist in the App Store, automate internal workflows, or connect Shopify to your other business systems like ERP, CRM, or WMS.
A public Shopify app is listed on the Shopify App Store and can be installed by any merchant. A private app is built exclusively for one specific store and is not publicly listed. Public apps require full App Store review, Billing API integration, and GDPR compliance. Private apps are faster to build and ideal for custom business logic.
Shopify Functions let you customise core Shopify backend logic, including custom discounts, shipping rates, payment filtering, and cart transforms, without maintaining a separate server. Checkout Extensions let you add custom UI components to the checkout page using Shopify's official extensibility APIs, replacing the deprecated checkout. liquid approach.
