    Answers to Your Questions Regarding Shopify Plus Service

    What's the difference between Shopify and Shopify Plus?

    Shopify Plus adds enterprise features standard Shopify doesn’t offer, including unlimited staff accounts, multiple expansion stores, native B2B functionality, checkout customization, and a 99.99% uptime SLA built for high-volume traffic.

    How long does a Shopify Plus design and development project take?

    Timelines depend on complexity, but most Shopify Plus builds take 8 to 16 weeks from strategy through launch. Migrations and headless builds typically fall on the longer end of that range.

    Can Ecomgiantz migrate our store from Magento or BigCommerce to Shopify Plus?

    Yes. We handle full migrations from Magento, BigCommerce, WooCommerce, and custom platforms, with a process built to protect your SEO rankings and preserve historical data.

    Do we need Shopify Plus if we're not doing B2B sales?

    Not necessarily for B2B alone, but high sales volume, multiple storefronts, or the need for checkout customization are common reasons DTC-only brands move to Shopify Plus too.

    What does "Checkout Extensibility" actually mean for our store?

    It means the checkout can be customized far beyond Shopify’s default, including custom branding, upsells, and business-specific logic, something standard Shopify plans don’t allow.

    Is Ecomgiantz a Shopify Plus design agency or a Shopify Plus development agency?

    Both. Design and development are handled by the same team on every project, which means your store’s visual identity and technical architecture are built together, not handed off between separate vendors.
