Frequently asked questions
What is a Shopify Plus developer?
A Shopify Plus developer builds on the enterprise tier of Shopify, using Plus-only features such as Checkout Extensibility, Shopify Functions, B2B, and Expansion Stores. I handle the custom checkout logic, performance, and integrations that high-volume Plus merchants need but cannot do on standard Shopify.
Can you migrate our checkout from Scripts to Functions?
Yes. I migrate legacy Checkout Scripts and checkout.liquid customizations to Checkout Extensibility and Shopify Functions, so your custom discounts, validation, and checkout UI keep working after Shopify's enforced deprecation deadlines.
Do you build B2B on Shopify Plus?
Yes. I set up B2B on Shopify Plus with company accounts, customer-specific catalogs and price lists, and custom B2B checkout and ordering flows, integrated with your ERP or CRM where needed.
