Frequently Asked Questions

Shopify Development FAQ

How much does it cost to hire a Shopify Plus development agency?

Shopify Plus development projects typically range from $15,000 for a focused build (custom checkout, theme customization, or single integration) to $150,000+ for a full platform migration with B2B features, multi-store setup, and ERP integration. We scope every project individually after a free discovery call, so you get a fixed quote with no hidden fees before any work begins.

How long does a Shopify Plus migration take?

Most platform migrations to Shopify Plus take 8 to 16 weeks depending on catalog size, data complexity, and custom integrations. A straightforward store with under 5,000 SKUs and standard integrations can launch in 8-10 weeks. Larger catalogs with custom B2B features, ERP connections, or multi-store setups typically take 12-16 weeks. We build detailed timelines during discovery so you know exactly what to expect.

Can you migrate my store from Magento, BigCommerce, or WooCommerce to Shopify?

Yes, we specialize in migrations from Magento (Adobe Commerce), BigCommerce, and WooCommerce to Shopify Plus. Our migration process covers product and customer data transfer, SEO preservation with 301 redirects, design rebuild, and integration reconnection. We have dedicated migration guides for Magento, BigCommerce, and WooCommerce, and have completed over 100 successful migrations with zero data loss.

Do you build custom Shopify apps and integrations?

Yes. We build custom Shopify apps, private apps, and API integrations using Shopify's REST and GraphQL APIs. Common projects include ERP connections (NetSuite, SAP, Microsoft Dynamics), custom checkout extensions using Shopify Functions, middleware for multi-system data sync, and custom fulfillment workflows. We also build Hydrogen headless storefronts for brands that need complete frontend control.

What B2B features can you build on Shopify Plus?

Shopify Plus has native B2B features that we extend and customize: company accounts with multiple buyers and locations, customer-specific pricing and catalogs, net payment terms (Net 30/60/90), volume discounts, quick-order forms, and self-service portals. We also build custom wholesale portals, integrate with existing ERP systems for real-time inventory and pricing, and set up automated B2B workflows using Shopify Flow.

Do you offer ongoing Shopify support after launch?

Yes. Many of our clients start with a migration or custom build and then move to an ongoing retainer for continuous development, optimization, and support. Retainer services include theme updates, new feature development, performance monitoring, app management, and strategic consulting. We become your long-term development partner rather than a one-time vendor.
