Supplier Core™

MainStem's Supplier Core allows you to easily list your products on our network of e-commerce marketplace sites and within our Purchase Pro™ software. You can also browse open RFQ's and submit your bids in real-time with customers. Most of our suppliers opt for our easy to use integrations into their e-commerce or ERP software (like Shopify, WooCommerce, EDI and more) for real-time syncing of your products, pricing, and availability. With an integration, orders are instantly input into your software as they are made on the MainStem Purchasing Platform.
