It's possible to set Codisto to not synchronize Price and/or Quantity.  This may be because there is another system (such as an inventory management system or repricer) that is set up to synchronize these elements of the listings on your connected sales channels.

To STOP Codisto synchronizing Price and/or Quantity:

1) Navigate to Attribute Mode from the Listings View, and select the sales channel you wish to turn off price or quantity sync for.

2) Check the relevant options in the 'Sales Attributes' section.  REMEMBER TO SAVE AND PUBLISH TO YOUR SALES CHANNEL BY CLICKING THE GREEN TOP BUTTON (ensuring you are editing the correct sales channel).
