Announcement reposted from Amazon Japan:
If you’re taking time off over the holiday season, or planning to work on public holidays, we recommend these simple steps to protect your seller-fulfilled order performance metrics.
Set up vacation mode
Set your account to vacation mode to avoid missing orders that could affect your performance. This setting temporarily removes your seller-fulfilled listings from Amazon product detail pages and search results.
To set up vacation mode, go to the Store status and Vacation settings page.
For more information, go to Listing status for vacations, holidays, and other absences.
Manage your holiday settings
If you plan to send seller-fulfilled orders on public holidays, go to the Holidays widget in Seller Central to override predefined holidays and change them to an “operating day”.
To override a public holiday, go to the Holidays page.
Note: Allow up to four hours for any change in holiday settings change to be reflected in your delivery promise and orders received.
For more information, including how to revert operating days to holidays, go to Manage Holiday Settings.
Consider setting up Customer Service by Amazon
If you’re unable to respond to customers, you can enable Customer Service by Amazon. It’s a paid program where Amazon takes care of customer service on your behalf for your self-fulfilled orders. Our team will answer any inquiries from your customers directly, 24/7, via phone, chat, or email.
To learn more, go to Customer service for seller-fulfilled orders.
Contact Account Health Support during the holidays
