Shopify Plus programmes break into four typical workstreams. Replatforming and migration, where the partner scopes the move from Salesforce Commerce Cloud, Adobe Commerce, BigCommerce, or SAP Hybris, runs the catalogue and customer migration, designs the URL and SEO redirect map, sizes the cutover risk and pilot-market approach, and maintains the legacy estate during dual-run. Storefront and headless engineering, where the partner builds the Liquid theme estate or the Hydrogen and Oxygen headless storefront, designs the section and metaobject taxonomy, sets the page-builder workflow for merchandisers, and configures the Shopify Markets multi-country pricing, language, and tax. Commerce extension and integration, where the partner builds the Shopify Functions discounts and checkout extensibility, integrates ERP, OMS, WMS, PIM, and CDP platforms via the GraphQL Admin API, and configures Flow automations for fraud, fulfilment, and customer-service routing. B2B and operations, where the partner enables B2B-on-Shopify for company accounts, price lists, draft orders, and net terms, sets the checkout-extensibility apps for compliance and post-purchase, and runs the operational handover including merchant academy and Plus support model.
Three procurement archetypes recur. Plus Premier and Plus Partner agencies (BVA, Diff, Eastside, We Make Websites, Statement, Swanky) lead at mid-market and DTC brands where merchandising craft, conversion-rate optimisation, and creative direction are the determining factors and total spend stays below $2m. Global SIs and Big Four (Accenture, Deloitte) lead at enterprise multi-brand and B2B replatforming programmes where ERP, OMS, and tax integration drive the business case. India-heritage SIs (TCS, Infosys, LTIMindtree) lead on managed run, multi-region rollouts, and ERP-anchored programmes where ongoing throughput matters more than agency polish. Friction point: Shopify Plus pricing is consumption-linked above a baseline plus revenue-share thresholds, and headless Hydrogen builds add a meaningful operating cost for Oxygen and CDN edge. Enterprise buyers replatforming from Salesforce Commerce Cloud or Adobe Commerce frequently underestimate the cost of custom checkout flows, third-party tax engines, and the apps stack required for parity with their legacy build, with three-year platform cost often running 30-60 percent higher than the initial business case.
