For buying organisations: punchout
Most large buyers do not shop on Amazon directly. Their procurement system (such as SAP Ariba, Coupa or an ERP purchasing module) opens an Amazon Business punchout session; users fill a cart and return it as a requisition for approval. The approved purchase order goes back to Amazon. Standards such as cXML and OCI handle the exchange.
Orders, invoices and reconciliation
After purchase, finance teams need orders, shipments, invoices and card transactions to match. Amazon Business offers integrations and APIs for ordering, reporting and reconciliation; the integration should post invoices to the ERP, match them to purchase orders and goods receipts, and flag differences for a person to review.
For sellers: reaching business buyers
- Business prices and quantity discounts set alongside consumer prices.
- Complete tax and VAT information so buyers receive valid invoices.
- Accurate product data that procurement catalogues can use.
- Reliable shipping promises, which business buyers weigh heavily.
These can be managed through the Selling Partner API like the rest of your catalogue.
Plan the governance
Decide early who can buy what, which approval rules apply and how categories map to your chart of accounts. Most problems in procurement projects are about rules and data ownership, not technology.
