Custom Apps, Checkout & Functions

When an app store plugin almost fits, the workarounds usually cost more than building it right. We build custom apps, admin tools, checkout extensions and Shopify Functions on Shopify's own APIs — maintainable, secure and upgrade-safe.

What’s included

  • Custom, private and embedded Shopify apps
  • Admin UI extensions and internal tools
  • Dashboards, bulk editors and merchant workflows
  • Checkout UI extensions and validation
  • Shopify Functions: discount, delivery, payment and cart rules
  • Complex discount engines and tiered promotions
  • Customer-specific and quantity-break pricing
  • Custom customer accounts and portals
  • GraphQL Admin and Storefront API work
