Custom Shopify logic

Shopify Functions & Checkout Logic

Custom discounts, shipping logic, validations, bundles, and checkout behavior for stores that need Shopify to do more than it does by default.

A lot of Shopify customization starts the same way: “We need Shopify to do this one thing it does not do by default.”

That might be a discount rule, shipping logic, checkout validation, cart behavior, bundle logic, or a Scripts migration that needs a more modern path forward.

We use Shopify Functions and related custom tooling to build that behavior in a way that fits the store’s actual requirements.

For some clients, that means a tightly scoped solution to one specific problem. For others, it becomes part of a broader custom app or managed platform that continues to evolve over time.

Either way, the goal is the same: give you the logic your business needs without forcing your team to become Shopify infrastructure specialists.
