By | February 17, 2026

We are thrilled to announce the GUMU™ powered Amazon–Sage 300c integration, yet another valuable expansion of our growing eCommerce-ERP integration portfolio. The GUMU™ powered Amazon–Sage 300c integration allows businesses to automate processes resulting in streamlining operations, eliminating manual data entry, providing a better customer experience and at the same time being complete accurate for sales, inventory and finance.

When you connect your Amazon shopping cart with your Sage 300c ERP system for real-time synchronization you are created an integrated atmosphere to manage customer orders, inventories and financials from a central point. Amazon is one of the largest ecommerce marketplaces in the world and when you combine this with the robust capabilities of Sage 300c you will allow your business to effectively manage all orders and fulfilments from one platform.

Key Benefits of the Amazon-Sage 300c Integration

Real-time Inventory Synchronization
Whether your business sells on Amazon, eBay or your own website, the integration of your shopping cart with your Sage 300c ERP provides one central repository of all inventories for sales. Automatic synchronization of inventory between your business and Amazon allows for accurate stock availability on your Amazon listings and helps prevent overselling or stock groups on your inventory level.

Accelerated Order Processing
All orders from Amazon are automatically imported into Sage 300c. This means you don’t have to manually enter customer orders in Sage 300c which eliminates mistakes when entering the order and further shortening the time needed to fulfil the customer’s order with respect to picking the products, printing the packing label and shipping the products.

Enhanced Customer Satisfaction
Your customers will see immediate benefits because they will have accurate product availability on your Amazon listings, quicker shipment of the products that they purchased and receive timely notifications of the shipment or delivery of the products that they ordered. All of these attributes improve customer satisfaction, thus creating repeat business for your company.

Increased Productivity by Utilizing Automation
Automated Solutions provide an accurate representation or an error-free transaction record, which decreases the need for human input (e.g., to change an existing entry due to an error made by a person). As a result, your team will now have more time to spend on areas such as customer service and growth because they will no longer need to devote tremendous amounts of energy and resources to fixing errors caused by manual data entry into your system.


Example Scenario of Integration

To help illustrate how GUMU™ integration works, let’s analyse this step-by-step scenario of the order of a backpack through an Amazon seller account.

Placing the order
The customer has made an order with an Amazon seller. During the order or ordering process, GUMU™ collects all of the information regarding that specific order (i.e., customer information, product details, shipping costs and taxes, and payment information). GUMU™ will then transfer that order information (data) directly to Sage 300c automatically.

Updating the inventory of the product
Sage 300c will automatically update its stock for the sold item, which will then automatically reflect the new available inventory level back to Amazon; therefore, the customer will always see an accurate representation of your inventory across multiple sales channels.

Processing the order
Once GUMU™ has transmitted the order information to Sage 300c, Sage 300c will begin to process that order just like you would in any other order processing situation, along with sending the order information to the warehouse for presenting and/or fulfilling that order. Upon receiving an order from Sage 300c, the warehouse will follow their standard operating procedures to pick, package, and ship the order.

Providing updates to customers
As the customer continues to receive updates throughout the order process (i.e., order confirmation, shipping information, delivery information, etc.), those updates will automatically synchronize between Sage 300c and Amazon.

Feature Highlights

  • Automatic syncing of the following order information – order, product, customer and inventory
  • All channels have real-time stock updates
  • Fast processing of orders with reduced manual action
  • Providing correct information on product availability and accurate customer feedback.
