3dcart (now called Shift4Shop) is a cloud-based eCommerce platform that enables you to build an online store, manage products, orders, customers, payments and marketing all in one place.
If you run or are building an online retail business (or aim to), you want fewer moving parts: hosting, checkout, payments, SEO, marketing, shipping integrations. 3dcart provides a single system with many built-in features, reducing the need for many third-party add-ons. That means less complexity, potentially lower cost, faster time-to-market. Also significant: since it was acquired by payments specialist Shift4 Payments in late 2020, it benefits from tighter payment/checkout integration.
You subscribe to the platform, pick templates or build your storefront, add products, configure payments/ shipping, then you can sell. It ties in inventory, order management, multi-channel (e.g., Amazon/eBay) support, SEO & marketing tools. The platform offers customization via themes/HTML/CSS, and has REST/API support for integrations.
