Shopify Plus Development Agency
Enterprise-grade Shopify Plus engineering — B2B commerce engines, checkout extensibility, headless storefronts, and custom app development for high-volume merchants.
What is Shopify Plus?
Shopify Plus is the enterprise tier of the Shopify platform, built for merchants processing significant volume who need advanced APIs, custom checkout experiences, B2B buyer portals, and dedicated merchant success management.
Opticlon specialises exclusively in Shopify Plus engineering — from bespoke checkout extension builds and B2B commerce configuration to headless Hydrogen storefronts and full ERP integration layers. We bring a senior engineering discipline to every build, treating the Shopify Admin API as a first-class production system.

Frequently Asked Questions
What is the difference between Shopify and Shopify Plus?
Shopify Plus is the enterprise tier of Shopify, offering advanced APIs (Checkout Extensibility, B2B, Multipass), unlimited staff accounts, Shopify Flow automation, exclusive merchant success management, and volume transaction pricing. It is designed for merchants processing over $1M/year.
How long does a Shopify Plus store build take?
A standard Plus store setup typically takes 4–6 weeks. A full headless Hydrogen build with ERP integration ranges from 8–14 weeks depending on complexity and data migration requirements.
Can you migrate us from Magento/WooCommerce to Shopify Plus?
Yes. We handle full data migrations including products, variants, customer records, order history, and SEO URL redirects — with zero storefront downtime during cutover.
Do you build custom Shopify apps for Plus merchants?
Absolutely. We architect private Shopify apps specifically for Plus merchants — covering custom B2B workflows, ERP sync, loyalty systems, and anything the native app store does not support.
