Integrate Sage 100 with Amazon Marketplace

Chances are, your company partnered with Amazon to offer your products to their 300 million global consumers.

Whether you are fulfilling the orders from your warehouse or having Amazon fulfill them, their
state-of-the-art e-commerce platform is hard to beat for seamless shopping experience, with fast,
flexible service and Prime shipping. With the increase in sales activity, there are measures needed
to automate the enormous amount data exchanged between your business and Amazon and meeting
Amazon’s communication and shipment standards is paramount.

That is where ROI comes in!

Fulfilled by Merchant (MFN)

Our most popular integration is for customers selling on Amazon Seller Central and fulfilling their own orders. Integration points typically include:

Amazon orders to Sage 100 sales orders

Orders coming in can find an existing customer by the e-mail address, set up a new customer account or send all the orders into one Amazon customer account. All the relevant data comes in with the order so there is no additional work on your end other than to process and fulfill.


Tracking, Shipment update and Inventory Quantity sync to Amazon

Once the order is picked, packed, and shipped, the Amazon platform is updated with the shipment confirmation and the order is closed. Inventory quantities-on-hand can also be kept in sync with the accounting system.

Fulfilled By Amazon (FBA)

For customers who qualify, Amazon will warehouse their goods and fulfill their orders. Every month, or sooner—depending on activity, in
addition to receiving the net income, Amazon will send the Payments report detailing sales, returns, credits and commission fees.
Integration for FBA typically includes:

Amazon orders to Sage 100 invoices

Similar to MFN order integration except the paid
orders coming into Sage 100 invoice data entry rather than sales order entry

Amazon Payments Report

Simplify accounting with an automated import of the credits, sales, returns, commissions – takes hours over work down to posting in minutes!
