FAQ
Questions about Shopify Plus.
What does a Shopify Plus agency do?
It builds, migrates and grows stores on Shopify Plus: checkout customisation with checkout extensibility, Shopify Functions, B2B, expansion stores, Flow automations and integrations with ERP, PIM and 3PL systems.
How much does Shopify Plus development cost?
It depends on the scope: design, checkout changes, B2B, the number of stores and integrations. We send a fixed, itemised quote within 48 hours of a free call. The Shopify Plus subscription itself is billed by Shopify.
Do I need a Shopify Plus Partner?
Not necessarily. What matters is that the team has built and maintained Plus stores and knows checkout extensibility, Functions and B2B. Ask any agency for Plus case studies and references before you hire.
Do we need Shopify Plus?
Not always. Plus makes sense when you need B2B on the same store, checkout customisation, several expansion stores, higher API limits or automation at scale. See our Shopify vs Shopify Plus comparison; we will tell you honestly if standard Shopify is enough.
Can you move us from standard Shopify to Plus?
Yes. The upgrade is done by Shopify on the same store. We then set up the Plus features you need: checkout extensions, B2B, Flow automations and expansion stores.
Can you migrate us from Magento, Salesforce Commerce Cloud or BigCommerce to Plus?
Yes, including products, customers, orders, URLs and redirects. See our Magento and BigCommerce migration pages.
