最近一票貨物5000個通過亞馬遜國際物流配送入倉，丟失了近400個貨物。
向亞馬遜索賠，提供了采購合同，交貨證明（海運入倉單）。
因為有6個月賬期，為符合亞馬遜要求，特意提前結(jié)算了貨款并補開了發(fā)票。
可是亞馬遜說發(fā)票日期不是發(fā)貨前的日期，拒絕賠付。
有沒有小伙伴遇到過類似問題的？這種問題該怎么解決呢？一定要求發(fā)貨前的發(fā)票，對于有賬期的賣家來說是否合理呢？在法律上站得住腳嗎？
求大佬解答!

以下是亞馬遜的case原文：

Hello from Amazon Selling Partner Support,

Thank you for your patience while we investigate shipment? FBA*********?
The purchase date on the invoice that you provided was after the shipment's ship date. We can't accept the invoice as proof of purchase because the goods were bought after the inventory was sent to a fulfillment center.
Please provide us with the invoice that you received upon purchase of the goods shipped in shipment FBA*********?
