In today’s digitally driven marketplace, managing disconnected systems is one of the fastest ways to lose time, money, and customers. If your online store runs on BigCommerce and your back-office financials rely on Sage ERP, integrating the two can completely transform how you do business. This blog is your complete guide to BigCommerce and Sage integration—what it is, why it matters, and how to implement it with B2Sell.

From syncing orders and inventory in real time to automating tax calculations and eliminating manual data entry, the benefits are endless when you connect Sage and BigCommerce. In this in-depth blog, we’ll show how integration works, key features to expect, common use cases, and how B2Sell’s Sage and BigCommerce integration helps you grow your business with less effort.

_{What is Sage and BigCommerce Integration?}

Sage and BigCommerce integration refer to the seamless connection between your BigCommerce online storefront and Sage ERP system (such as Sage 100, Sage 300, or Sage X3). With this integration, data like orders, inventory, pricing, customer information, and financial records can flow automatically between the two platforms.

Rather than entering the same data manually into both systems—which is time-consuming and error-prone—an integration ensures:

• Sales orders placed on BigCommerce automatically reflect in Sage

• Inventory updates in Sage are shown in real-time on BigCommerce

• Customer and shipping details sync between platforms

• Invoices, taxes, and financial data are accurate and up to date

This bidirectional integration bridges the gap between your front-end and back-end operations—saving time, reducing costs, and enabling scalability.
