Square Online vs BigCommerce

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.

BigCommerce is a cloud-based, SaaS e-commerce platform designed to empower merchants — from fast-growing brands to large enterprises — with a richly featured, scalable solution.

It supports online storefront creation, multi-storefront management, omnichannel retail, B2B workflows, headless commerce, and powerful built-in marketing and analytics tools.

Renowned for strong security (PCI DSS compliance, SSL, 2FA) and high ROI capabilities, it enables sellers to launch and scale without coding. As
