Storeline

A single-vendor storefront with a custom-themed Medusa engine underneath

Storeline is a launch-ready single-vendor storefront under your brand. It pairs a fully custom Next.js storefront with Medusa as the headless commerce engine, so the customer-facing experience is yours from the first pixel and the merchant-side admin (catalog, orders, fulfillment, gift cards, discounts) gets the mature tooling that a Shopify-replacement actually requires.

Key features

  • Custom storefront on your domain — no Shopify or Squarespace branding
  • Catalog with variants, bundles, gift cards, and digital products
  • Cart, checkout, and Apple/Google/Klarna pay via Stripe
  • Discount codes and automatic discounts with stacking rules
  • Faceted product search via Algolia, themed to match
  • Order management with status emails, partial shipments, and returns
  • Fulfillment integration with ShipStation or Shippo
  • Tax via TaxJar / Avalara, themable PDF invoices and packing slips

What you get

Storeline launches as your branded storefront on your domain, with a Medusa-powered admin where catalog, orders, and fulfillment live. Stripe is wired on day one; Klaviyo or Sendwave handles marketing email; ShipStation or Shippo handles fulfillment. The first product import runs from CSV or a Shopify export.

Sample customer story (placeholder — illustrative only)

A 12-person D2C cookware brand licensed Storeline to escape the Shopify ecosystem after a theme they had paid to customize broke for the third time on a Shopify platform update. A 14-day rebuild gave them a storefront they own, an admin their ops team didn’t have to relearn, and a 30% lower platform fee at their GMV.

What’s NOT included

  • Multi-vendor / marketplace. Storeline is single-merchant by design; for two-sided, see Bazaar.
  • Subscription / recurring orders out of the box. Available as a paid customization, or shipped as Subbox if subscriptions are the primary model.
  • Brick-and-mortar POS. Counterpoint is the answer for in-store and inventory-across-locations.
  • B2B wholesale price lists with credit terms. Available as a paid Pass-2 add-on.
