This API allows first-time Sellers to price their products with confidence and experienced Sellers & repricers to optimize pricing to stay competitive.

Receive a push AOCN notification for B2B whenever there is a change in any of the top 20 B2B offers, in the form of any price change (either single unit or quantity discount tier prices) for an item listed by the seller. The top 20 B2B offers are determined by the single-unit landed price, which is the price plus shipping. If multiple sellers are charging the same landed price, the results will be returned in random order.

As part of improving Delivery Experience for business customers we are focusing on two features:

1. Improving BHDR (Business Hour Delivery Rate): Business customers, similar to B2C, expect fast, on-time deliveries successful on first attempt, but they also expect adherence to their delivery preferences, such as ensuring packages are delivered within their operating days/hours (e.g., Mon-Fri 9am-5pm) and to their preferred delivery area. To support that growth and improve business delivery experience for MFN (Seller Fulfilled) products, we have added new attributes, such as business hours, business days and delivery instructions, to the existing Orders API. We have also launched a BHDR metrics report within seller central that help sellers measure success rate of first attempt of deliveries.

Steps to improve BHDR :
a. Make a call to the Orders API and upon receiving successful response check the attribute value of isBusinessOrder in the payload
b. if the result of above validation is "true" then call getorderaddress operation and check the address type = Commercial
c. If above validation holds true then filter the carrier selection to exclude any options with Estimate Delivery Date on a weekend

2. Print PO (Purchase Order number) on the labels: Business customers use the PO number to route packages that are delivered or to reconcile the order for payment. Without a PO number on the label and packing slip, packages may be undeliverable to the end customer and may delay payment. To learn about retrieving the PO number click here and then print it on the shipping labels.
