The Purchase Order Number (PO Number) in Amazon Business is an order identifier assigned by the buyer, not by Amazon.

In a B2B context, a company may optionally create an internal order (Purchase Order) before making a purchase, assigning it a unique number. When completing the purchase on Amazon Business, they can enter that number in the “Purchase Order Number” field during checkout.

What is it used for?

• Internal order tracking: it allows the company to reconcile the purchase with its own management system, department, or project.
• Accounting facilitation: the PO Number appears on the invoice, making it easier to match expenses with the budget.
• Cost center management: each department can have different POs.
• Refunds and internal controls: it simplifies approval and archiving.

bindCommerce manages the Purchase Order Number that Amazon Business customers enter during purchase. This number can be:

• Displayed through the bindCommerce administrative interface
• Transmitted via API to the seller’s ERP and then printed on invoices or included in reports
• Used in shipping labels

Viewing the PO number in the bindCommerce interface

For Amazon Business orders, the PO number is automatically downloaded and saved in the bindCommerce database. It can be viewed by navigating the menu:

Sales > Attributes > Sales Attribute Values

The attribute name is AmazonPurchaseOrderNumber

PO number export with the order export API

The order parameter is automatically exported in the API export documents, in the <Params> section of the order with the key AmazonPurchaseOrderNumber.

For more information, consult the API Export Documents guide.

Once acquired by the seller’s ERP, it can be printed on the invoice or included in any reports managed by the ERP itself.

Use in shipping labels

Transmission to bindCommerce Shipping

To be used in shipping labels, the attribute must be included among those transmitted to bindCommerce Shipping. To achieve this, the attribute must be included in the BSHIPPING_EXPORT_ORDERS export configuration, in the order_attributes section, under the name purchase-order-number (from the menu System Parameters > Custom Parameters).

For example, for the connector with id = 3

After being transmitted to bindCommerce Shipping, it will be visible in the individual orders that contain it, and then copied to the related shipments.

 

The seller can decide where to print this data, based on the configurations allowed by each individual courier managed by bindCommerce Shipping and depending on the available space.
