FAQ

Common questions.

How much does custom Shopify development cost?+

Custom Shopify work is scoped to the build — a bespoke theme, custom app, integrations, and any Plus-only checkout work each add to the estimate. We give a fixed-scope, phased quote after a short discovery so there are no surprises.

Do you build custom Shopify apps?+

Yes — we build private and custom Shopify apps for bespoke logic, third-party integrations, and automations that off-the-shelf apps cannot handle, without piling on app bloat.

Can you customize the Shopify checkout?+

On Shopify Plus we use checkout extensibility and Functions to tailor the checkout, upsells, discounts, and B2B flows. On standard Shopify the checkout is more constrained, and we optimize everything up to and around it.

Shopify vs Shopify Plus — when should I upgrade?+

Plus is worth it when you need checkout customization, higher API limits, wholesale/B2B, multiple storefronts, or advanced automation. We help you weigh the added cost against the features your growth actually requires.

Will adding apps and features slow my Shopify store down?+

Not the way we build. We work performance-first, remove redundant app scripts, and keep the theme lean — so speed and Core Web Vitals improve rather than degrade as you add capability.
