We provide the ability to add a percentage or fixed fee to your rate prices. We've included an example of how the adjustments are calculated below.
In the example above the merchant had a base delivery fee of $12 and a rate adjustment of 18%.
The rate adjustment is calculated on the Subtotal of the order. Based upon this 18% rate adjustment the total delivery fee becomes $16.34.
Rate adjustment: $24.15 * 0.18 = $4.34
