For most Amazon listings, Listing Mirror is not editing or managing any of the actual listing information. Listing Mirror will import the information from Amazon's marketplace, but the only things we will send out are Price (if you are set to send price from LM), MF Quantity, and MF Leadtime.
MF Leadtime is the amount of time you as a merchant are allow to have between accepting the order and providing shipping information to prove that the order has shipped. If you have FBA filling your Amazon orders, it's not likely something you've needed to handle, but if you sell (or begin selling) MF on Amazon, you will need to be aware of your MF Leadtime.
By default, Amazon's MF Leadtime is set to , if you want to set it longer than that, you can go into your channel integrations settings and set it on an integration level:
Or, if you have specific items that take a little longer to send out, you can set the MF Leadtime on an individual level by going into an Amazon listing to edit it in Listing Mirror:
Just change the MF Leadtime from within the listing itself:
This will only affect that specific listing.
