To copy rates from one unit to another click on the ‘copy rates to another unit’ button at the top of your finished tariff. The pop up below will appear. Choose which unit you want to copy the current tariff to. If you are copying between tariffs make sure you have created the target tariff before you try to copy the rates.
Please note: Copying rates over to another unit, when you’ve already put in rates for it, will permanently overwrite the rates you put in for that unit previously. So please use this super quick fix with caution!
