Migration Best Practices

Avoid common migration pitfalls with these approaches:

1. Time it right

Never migrate during peak sales periods. Choose a quiet week and schedule the actual switch for early morning when traffic is lowest.

2. Audit apps thoroughly

Some apps have Plus-specific versions or become unnecessary with Plus features. Review every app before migrating.

3. Plan checkout rebuild

checkout.liquid was deprecated. Rebuild checkout customisations using checkout extensibility APIs before going live.

4. Use a Plus Partner

Partner experience with migrations and Plus features typically pays for itself through faster implementation and fewer issues.

Frequently Asked Questions

Consider Shopify Plus when you consistently exceed 500k GBP monthly revenue, need checkout customisation, require B2B functionality, want to expand internationally with dedicated storefronts, or need advanced automation through Shopify Scripts and Flow. Also consider Plus if you are hitting staff account limits, need exclusive apps, or want dedicated support through your Merchant Success Manager.
Shopify Plus starts at approximately 2,000 USD per month, with pricing that scales based on your revenue. Variable fees apply above certain thresholds. While significantly more expensive than standard Shopify plans, Plus often delivers positive ROI through checkout conversion improvements, reduced app costs (Scripts replaces discount apps), and operational efficiency. Calculate the specific ROI for your business before upgrading.
Shopify to Plus migrations are relatively smooth since you stay within the Shopify ecosystem. Your products, customers, orders, and theme all transfer automatically. However, checkout customisations need rebuilding using checkout extensibility (checkout.liquid was deprecated), and some apps may have Plus-specific versions or replacements. Plan for some adjustment time, and avoid migrating during peak sales periods.
Shopify Scripts are Ruby snippets that run on Shopify's servers, enabling complex promotions that standard Shopify cannot achieve. Create tiered discounts (spend 100 get 10% off, spend 200 get 20% off), automatic gifts with purchase, customer-specific pricing, or complex BOGO offers without apps. Scripts are exclusive to Plus and can replace multiple paid apps whilst providing faster, more reliable checkout experiences.
Shopify Plus includes native B2B functionality allowing wholesale and trade customer management. Create company accounts with multiple buyers, set customer-specific price lists, offer payment terms (net 30, net 60), set minimum order quantities, and provide volume-based pricing. B2B customers see their specific pricing throughout the store. This replaces third-party wholesale apps for many merchants, reducing complexity and improving the buyer experience.
While you can technically migrate yourself, working with a Shopify Plus Partner provides significant advantages. Partners have migration experience, understand Plus-specific features, can implement checkout customisations effectively, and provide post-migration optimisation. Plus Partners also have direct lines to Shopify support for complex issues. The cost of partner support is typically offset by faster migration, fewer issues, and better utilisation of Plus features from day one.
