eCommerce Platform FAQs

Can I manage my eCommerce website and physical store in one system?

Yes, Celerant allows you to manage both your eCommerce platform and point of sale in a single, fully integrated system.

Cumulus eCommerce is a cloud-based, template-driven solution designed for faster setup and ease of use, while Stratus Enterprise offers a fully customized eCommerce experience tailored to more complex business needs.

Cumulus eCommerce allows retailers to customize their website using built-in templates and fields, including changes to design, product displays, pricing, and promotions through an easy-to-use interface. Stratus Enterprise offers more advanced customization options, but changes are typically handled with the help of Celerant’s team to ensure performance, stability, and scalability.

Can I dropship orders placed on my eCommerce website?

Yes—Celerant makes drop shipping seamless by automatically routing online orders directly to your distributors for fulfillment.

Through Celerant’s distributor integrations, you can pull and display product feeds from your vendors directly on your website, including images, descriptions, and available inventory. As orders come in, they are sent to your suppliers for shipment—either directly to the customer or to your store for in-store pickup. This enables you to offer an “endless aisle” of products without the cost or complexity of stocking additional inventory. Celerant offers distributor integrations across a wide range of industries, including sporting goods, apparel, pet supplies, hardware, paint, and specialty items.

Does Celerant’s eCommerce offer an open API for integrations?

Both of our platforms—Cumulus and Stratus eCommerce—also offer a wide range of third-party integrations. Stratus eCommerce can also be customized to support nearly any additional functionality your business requires, giving you flexibility without sacrificing performance or stability.
