Overview

We start with an audit of your current Plus setup, then design an architecture that fits your roadmap. Delivery includes custom checkout extensions, B2B logic, multi-market configuration, and performance hardening. We QA against Core Web Vitals and provide documentation plus a clear handoff. Post-launch, we offer a support window and optional retainer for iterations.

FAQ

Can you customize checkout on Plus?

Yes. We use Checkout UI Extensions and Cart/Checkout Functions (no legacy checkout.liquid). Custom blocks, validation, and transform functions are all supported.

Do you support B2B pricing & net terms?

Yes. We configure B2B storefronts, volume pricing, net terms, and custom catalogs using Shopify's B2B features and custom logic where needed.

Can you migrate from Magento/BigCommerce?

We focus on build and architecture on Plus. For migration we can outline the approach and work with your data; for large catalog migrations we often partner with migration specialists.

How do you handle app + theme conflicts?

We audit your current theme and apps, then design extensions and code that avoid conflicts. We test on staging and use feature flags where appropriate.
