Shopify or Shopify Plus?

Shopify Plus is not automatically the right choice because a brand is large. Investigate Plus when you need B2B beyond the standard plans, such as unlimited catalogues or company-specific pricing, run multiple stores or complex market structures, have advanced checkout or automation requirements, or need stricter roles and governance. Weigh the platform cost against the cost of apps, custom work, manual effort and risk on the alternative.

Our Shopify services

A Shopify agency should deliver more than a storefront. The store has to work with product data, fulfilment, marketing, finance and retail, and your team has to be able to run it after launch. That is why we scope design, development and integrations together. Each service below belongs to that one approach and is not a separate product.

  • New Shopify and Shopify Plus stores, from discovery and UX/UI to theme development, analytics and launch.

  • Migration and replatforming from Magento, WooCommerce, Shopware, Lightspeed or a custom platform.

  • B2B on Shopify with company accounts, catalogues, price agreements and payment terms.

  • PIM and ERP integrations with clear data ownership, sync rules and error handling.

  • Shopify POS for brands that sell in their own stores as well as online.

  • Headless Shopify when content, channel or performance requirements justify the extra architecture.

  • Conversion optimisation and ongoing development after launch, driven by data and a prioritised backlog.

Custom work is not a goal in itself. We use Shopify’s standard features where they cover the need, choose an app when the business case holds, and build our own only when the standard options clearly fall short. For most brands a custom Liquid theme is the most manageable route. Headless only pays off when the requirements are worth the extra architecture and maintenance.

F.A.Q.

We’d love to answer all your questions

What is the difference between Shopify and Shopify Plus?

Both run on the same platform, with the same hosting, security and checkout. Shopify Plus adds what larger and faster-growing brands need: customising the checkout itself, expansion stores for other countries, brands or wholesale, Launchpad for scheduled campaigns, more room for B2B, more staff accounts and priority support. Upgrading does not make your storefront better on its own; it widens what you can adapt and automate.

When do we need Shopify Plus?

Usually when one of these applies: you want to change the checkout beyond the standard settings, you run several stores for different countries, brands or wholesale, you sell B2B at a scale where the limits of the regular plans get tight, or your revenue is high enough that the lower payment rates on Plus offset the plan price. If none of that applies, a regular Shopify plan is often the better choice.

What determines the cost of Shopify Plus?

Shopify Plus is a monthly subscription with a variable part that grows with your revenue, so the plan cost depends on your volumes and your contract. Shopify publishes the current rates on its pricing page. The plan is usually not the biggest item: apps, development, integrations and maintenance often weigh more. In an intake we map the full picture, so you can compare it with your current platform.

Can we start on Shopify and move to Plus later?

Yes. Upgrading to Shopify Plus happens within the same store: products, customers, orders, theme and apps stay where they are, so there is no migration. What you do need to plan is how you will use the Plus features, such as checkout customisation or expansion stores, because they only add value when they are set up with a clear purpose.

Do we need Shopify Plus for B2B?

Not necessarily. Since April 2026, B2B features such as company accounts, catalogues and payment terms are available on all Shopify plans, with a limit on the number of B2B catalogues outside Plus. Plus becomes relevant when you sell to many customer groups with their own price lists, run a separate wholesale store, or need checkout rules per customer. We look at your price structure first and advise from there.
