You can now change the handling time of your items on Amazon using our dashboard. When you setup your account with us the handling time is 1 day by default.
How can you change it?
Go to Settings --> Store Settings
Then go to Handling Time
Once you change the handling time, you need to re-export your items that was already listed.
You can re-export your items by simply clicking the export one by one. Or you can re export in bulk.
Please contact us if you have any questions.
