What is 4SELLERS?

4SELLERS is an ERP commerce platform for businesses selling through online shops, marketplaces and, where relevant, physical stores. It brings together purchasing, stock management, order processing, warehousing, dispatch, returns and accounting. Rather than maintaining orders, customer details and stock figures across several disconnected applications, teams can work from a shared source of information.

The platform is particularly suited to medium-sized retailers, wholesalers and mail order businesses with more than one sales channel or demanding day-to-day processes. Depending on the requirements, Sage 100 or Microsoft Dynamics 365 Business Central can provide the underlying ERP system. 4SELLERS adds commerce-specific functions and connections to other applications. The final set-up depends on the systems already in use and the way a business sells its products.

For retailers, a major benefit is having orders and stock information in one place. Orders from connected shops and marketplaces feed into the central process. Product information can be adapted for individual channels, stock levels are synchronised and orders continue through the ERP system. This reduces repeated data entry and helps prevent items being sold when they are no longer available. Marketplace connections include Amazon, eBay, OTTO and Kaufland.

Warehouse operations are covered too. 4SELLERS supports multiple warehouses, handheld data capture, different picking methods and dispatch management. Its multi-carrier connection handles shipping labels and tracking details within the logistics workflow, without the need to switch between separate carrier portals. Returns can follow rules that suit the business, from a customer's request through inspection and stock adjustment to a refund.

Businesses also have a choice of shop solutions. The company's own 4SELLERS shop system is designed for more complex B2B requirements, with a particularly close connection to Sage 100. Alternatively, Shopify can be linked to Sage 100 or Microsoft Dynamics 365 Business Central. In both approaches, the ERP remains the main source for product prices, stock information and documents.
