FAQ

What does a Shopify Plus development agency do?

A Shopify Plus development agency designs, builds and maintains stores on Shopify Plus, the enterprise plan of Shopify. Typical work includes custom themes, multi-store and multi-currency setups, B2B wholesale features, checkout customization with Checkout Extensibility, Shopify Flow automation and integrations with ERP, CRM and 3PL systems.

How much does Shopify Plus development cost?

Cost depends on the number of stores, custom features and integrations. At SPLIT Development, Shopify Plus builds start from $12,000. The Shopify Plus subscription itself is billed separately by Shopify.

How long does a Shopify Plus build take?

A Shopify Plus build usually takes 8 to 16 weeks, depending on the catalog, the number of storefronts and the systems to connect. Feedback speed on the client side moves the timeline as much as the scope.

Do you build Shopify Plus B2B stores?

Yes. SPLIT Development sets up Shopify Plus B2B with native features: company accounts, customer-specific price lists, gated catalogs, net payment terms and wholesale ordering, either on the same store as DTC or on a separate storefront.

Can one brand run several stores or markets on Shopify Plus?

Yes. Shopify Plus supports several storefronts under one organization. For Meroda Cosmetics, SPLIT Development runs five stores (EU, NL, IT, DE, CH) on Shopify Plus with a per-market interface. The brand’s average order value across the store group rose 22% and abandoned carts fell 31%.

Is SPLIT Development a Shopify Partner?

Yes. SPLIT Development is a Shopify Partner agency operating since 2019, with offices in Tallinn, Estonia and Sacramento, California. The team builds Shopify and Shopify Plus stores for DTC brands in the US, UK and EU and is rated 5.0 on Clutch across 66 reviews.
