你應該有收到關于“企業買家和企業賣家賬號”的郵件通知吧？（在Seller Central里有相關內容）
如果你創建的不是企業賣家賬號，那你不用做什么；
如果是企業賣家賬號的話，需要提供帶有訂單號的商業發票，那些績效評級也不一樣。

我也碰到了“Business Buyer”，去問seller support，收到這個回復：
“I thought I would provide some general information and links to help you, and any other interested seller, learn about the Amazon Business Seller program.?

I hope this helps!”
他說這是亞馬遜的“Business Seller program”，幫助賣家提升b2b的銷量，吸引更多的企業買家前來購買產品

這個賬號既是買家賬號，同時也開通了賣家賬號。

據說Amazon在測試B2B，對于賣家的B端是有篩選性的，目前尚不知具體情況，建議咨詢Amazon客戶經理，判斷真實性~

聽別人說，是亞馬遜首次嘗試與史泰博（Staples，辦公用品公司）進行競爭，所以希望那些出售辦公用品的賣家可以多和企業買家合作，進行交易。。。
