Square Online vs Sellfy

Square Online is an all-in-one ecommerce and website builder platform that allows businesses of all sizes—especially those already using Square’s POS system—to build professional online stores with ease.

With drag-and-drop editing, theme templates, custom fonts, and site elements like banners, item badges, and configurable layouts, it gives freedom to control branding and design.

Stores can connect custom domains (in paid plans), remove Square branding, list unlimited products, manage inventory, sync with physical store operations, and integrate with social media and Instagram.

Sellfy is a creator-friendly ecommerce platform built for selling digital products, physical merch, print-on-demand goods, subscriptions, and more—without transaction fees built into the platform.

It offers built-in marketing tools such as email marketing, cart abandonment, upselling, discount codes, and affiliate programs to help increase revenue.

Store customization is flexible with ability to use custom domains and branding, responsive design, embedded storefront widgets, and support for storefronts as well as widgets integrated into existing sites.
