Shopify Plus Development Agency for US & EU DTC and B2B Merchants

Both, but with a clear opinion. For most merchants under 50M USD GMV, a well-built Liquid theme (Online Store 2.0 with sections everywhere, custom Liquid + Alpine.js for interactivity) gives 90 percent of the result at 30 percent of the cost. Hydrogen + Oxygen makes sense when you need a real frontend product (rich product configurators, account dashboards, multi-locale routing with logic Shopify Markets cannot express, or shared design system across web and a Remix-based admin). We ship Hydrogen on Oxygen with Remix routing, the Storefront API 2024-10+, and Customer Account API for the logged-in surface. We will not push you into headless because it is fashionable — the cost is real and so is the operational overhead.

Shopify Functions in Rust or JavaScript are the replacement for Shopify Scripts and the right answer for any cart, checkout or delivery customization on Plus. We write Cart and Checkout Validation Functions (block invalid combinations of B2B SKUs, enforce minimum order values per company location), Discount Functions (BOGO with custom rules, tiered B2B pricing that depends on company tag), Delivery Customization Functions (rename, hide, or re-order shipping methods per cart), and Payment Customization Functions (hide payment methods per market or per company). All Functions are deployed via the Shopify CLI in a Git repo with CI per dev store → production, and we monitor Function execution time against the 5ms p99 budget Shopify enforces.

Yes. The hard parts are not the catalog import (we use Matrixify or custom ETL via the GraphQL Admin API 2024-10+ for that) — they are the URL redirect map (we keep your earned SEO equity), the customer password rehash (Shopify does not import hashed passwords, so we use a force-reset email flow), the historical order migration for support continuity, the metafield design for attributes Shopify does not have a native field for, and the tax/region setup for EU VAT including OSS and IOSS. A typical Magento 2.4 to Shopify Plus migration runs 10 to 14 weeks. We write the cutover runbook with rollback steps and run it on a Friday night with the merchandising team in the call.

Yes — Shopify B2B is now mature enough to replace most dedicated B2B platforms. We configure Companies with multiple locations, catalogs per company (or per company tag), volume pricing, quantity rules, payment terms (Net 30/60/90) via Shopify Payments, and the B2B customer account experience on Hydrogen or Liquid. Where the native B2B surface ends, we extend it: custom quote-to-cart Apps with Customer Account UI extensions, Shopify Flow automation for credit-limit checks, and integration to your ERP (NetSuite, SAP B1, Microsoft Dynamics) via the GraphQL Admin API with proper rate-limit handling against the cost-based query bucket.

Shopify Markets is the answer for most multi-region setups. We configure markets per country or region, presentment currencies via Shopify Payments multi-currency, EU VAT collection per market (with proper Intra-EU OSS registration handling), IOSS for sub-150 EUR orders shipped from outside the EU, market-specific catalogs, market-specific pricing rules, and domain strategy (subfolders vs ccTLDs depending on SEO posture). We sign a DPA, configure GDPR-aligned customer data handling, and document the Article 30 record of processing your DPO will sign. GDPR-aligned · ISO 27001 ready · SOC 2 Type II in progress.

Two models. Dedicated team from 12,000 EUR/month: senior Shopify developer (Liquid + Functions), Hydrogen/Remix frontend engineer, solutions architect at 25 percent, with weekly demos and quarterly roadmap reviews. Replatform sprint from 25,000 EUR fixed: scoped 10 to 14 week migration from Magento/BigCommerce/WooCommerce to Shopify Plus, including data migration, redirect map, theme rebuild, B2B setup, and cutover runbook. Three-month minimum on retainers, then month-to-month. We are listed in the Shopify Plus Partner directory and every developer is current on the Shopify Partner Academy certifications.
