最左边和最右边都是绩效问题，包括ODR,invoice defect rate.Late dispatch rate,Cancellation rate,valid tracking rate，一旦指标超标，亚马逊就可能来查你账号，我来调查一下，有多少人是被亚马逊的72小时紧急来电叫醒的？来电惊魂。有多少人认真看过亚马逊的后台政策？
订单缺陷率是衡量您能否提供良好买家体验的主要指标。该指标是在给定的 60 天内，存在一种或多种缺陷（定义见下文）的所有订单占订单总数的百分比。
政策规定，卖家应维持低于 1% 的订单缺陷率，才能在亚马逊商城销售商品。如果订单缺陷率高于 1%，可能会导致账户被停用。
取消率（在【账户状况】页面是指配送前取消率）包括所有卖家在给定的 7 天期限内取消的订单数量占订单总数的百分比。取消率仅适用于卖家自配送订单。
政策规定，卖家应维持低于 2.5% 的取消率，才能在亚马逊商城销售商品。如果取消率高于 2.5%，可能会导致账户停用。
延迟派送率包括在预计发货日期之后才完成发货确认的所有订单。 延迟派送率表示为 10 天或 30 天期限内延迟派送的订单数占订单总数的百分比。 。 延迟派送率仅适用于卖家自配送订单。
政策规定，卖家应维持低于 4% 的延迟派送率，才能在亚马逊商城销售商品。延迟派送率高于 4% 可能会导致账户被停用。
有效追踪率是指在给定的 30 天期限内具有有效追踪编码的所有货件占总货件数的百分比。有效追踪率仅适用于卖家自配送订单。
亚马逊买家使用追踪编码来了解订单配送状态和预计收货时间。有效追踪率是一项可以反映这些期望的绩效指标。目前，包括 USPS、FedEx、UPS 和 DHL 在内的所有主要承运人都提供免费追踪服务。
政策规定，卖家的货件应维持高于 95% 的有效追踪率。如果某个商品分类的有效追踪率低于 95%，我们可能会限制您销售此分类下非亚马逊物流商品的权限。这还可能影响您参与优先配送和保证配送的资格。
政策规定，卖家的发票缺陷率应低于 5%，这样才能在亚马逊商城销售商品。如果发票缺陷率高于 5%，可能会导致您的账户被停用
Dear Amazon Performance team
Thanks for your reply, and we have made an updated POA to resolve the issue and prevent the similar problem from happening again in the future
Here is the problem and the reasons:
1. Some of our buyers have not received their orders or have not received the orders on time
2.We have listed against detail pages that do not exactly match our inventory.
1,After we sent our packages to our cooperated logistics place, they really showed the tracking numbers to us, but they delayed our package and did not send the package to our customer right now, because they received too many packages from other sellers.
2,We did not arrange the employee to check the production work, our supplier produced many defective bags, and we did not carefully check the quality of the bags and didn’t remove the defective bags in time. Then we sent the bags to our customers directly.
3,We did not designate an employee to conduct a comprehensive check on our listings details, whether it is consistent with our inventory or not.
Actions made for solution:
1.We have showed our apology to the customers who did not get the packages and provided full refund to buyers whom don’t want to wait or sent a new product to buyers whom still want to wait .
2.We have deleted all the asins that the descriptions on the amazon does not match our inventory!
3. We have stopped the cooperation with the old Logistics company whose service is not good
4,We have stopped the cooperation with the supplier who provided us with low quality bags, and we promise we will never cooperate with the supplier in future!
5, We have set up a professional team to inspect the other listings to make sure that there is no ambiguity, such as: pictures,titles,bullet points, descriptions, brand, manufacturer, UPC, edition, binding,quantity, size, package and color, search teams etc.
6，Now we set up a quality inspection team to check all of our products in our warehouse!
Plan and prevention actions similar problem will happen in the future:
1.We will expand our plant size, increase productivity, prepare goods in advance, deal with the arrival of the season, to avoid excessive orders led to the occurrence of out of stock situation.
2. We will inform customers of the latest delivery news so that they can know about the status of the items they buy.
3.we will hire professional IPR team to do on site due diligence checking before we cooperate with any supplier.
4. We will choose a reliable ,stronger and faster logistics company to make sure our customers are satisfied with our shipping service.
6. In order to avoid late delivery, we will try to use FBA service in the future, we already have a staff dedicated to FBA to make sure our customer get the products on time.
7.Every week，our professional handling team will conduct a full audit of our inventory and listing details,inspect all inventory against detailed product information and listing details to ensure they match 100 percent, including title, description, images, bullet points, & search term
Now we have clearly realized our mistake! We really want to build a long cooperation with amazon, we will strictly abide by the rules and policies of the platform! We will strive to provide buyers with quality shopping experience! Hope Amazon give us a chance ！we promise never to make mistakes again! Looking forward to your reply!
