Go Price Lists via the Settings tab on your main app manager.
Click on Import/Export Price List.
The following popup will appear:
Choose your Price List from dropdown box.
Download the Price List CSV template.
The only thing you can edit is your price.
Note that if you leave the Price column blank on the CSV, no changes will be made to the price. However, If you need to set the price to 0, then you will need to add the value '0' itself to the relevant field(s).
Upload the CSV file and click Upload File.
And you’re done!
