Dear Seller,

Your sales proceeds will be delayed while we are reviewing your account. Starting today, the reserve period for all of your orders will be 14 days after the delivery date. For example, if you ship an item on January 1, and the actual delivery date is January 4, then the sales proceeds will be available for disbursement starting on January 19.

Please continue to ship your orders and only list items that you can ship by the expected ship date.

You can learn more about payment policies (https://sellercentral.amazon.com/help/hub/reference/external/G69122?locale=en-US)

Why is this happening?

Your reserve period is determined based on an assessment of your overall risk and historical performance.

Our policy regarding Selling Policies and Seller Code of Conduct can be found at https://sellercentral.amazon.com/gp/help/G1801.

How can I move back to a 7-day reserve period?

Factors that influence your reserve period include credit card charge success rates and A-to-z Guarantee claims, as well as other risk factors. We may move your account back to a 7-day reserve period based on changes in these risk factors. This will not require any action from you. We will notify you if you are reverted back to a 7-day reserve period.
