Our latest rates feature allows merchants to use Zapiet - Pickup + Delivery rates without needing access to Shopify Carrier Service API. Take a look at our Zapiet - Pickup + Delivery rates article for more details.
Fallback rates do not apply to Zapiet - Pickup + Delivery rates feature, only the Rates with the Carrier Service API.
Only proceed with this article if, because of the limitations of our newest rates feature, you need to use our rates with the Carrier Service API.
Within Zapiet - Pickup + Delivery, you can integrate with carriers that calculate more complex rates. We provide the ability to add a percentage of the rate or a fixed fee to the rates provided by these apps.
Percentage handling fee
This will take the rate provided by the carrier (Zapiet - Rates by Zip Code), and add a percentage of this rate to the shipping fee.
The final rate will be calculated by the following formula:
Final rate = original rate + the percentage of the rate
Example calculation
The percentage fee has been set as 10% of the original rate.
In this example, the original rate is £50.
Following the above formula, the rate the customer will pay is the original rate + the handling fee.
In this example, it is £50 + (10% of £50) = £55.
Fixed handling fee
This will take the rate provided by the carrier, and add a fixed fee to the shipping fee.
The final rate will be calculated by the following formula:
Final rate = original rate + the fixed fee
Example calculation
The fixed fee has been set to £10.
The original rate has been set to £50.
Following the above formula, the rate the customer will pay is the original fee + the fixed fee.
In this example, it is £50 + £10 = £60.
Percentage and fixed handling fees
If you add both a percentage and a fixed fee, the rate will be calculated by first finding the percentage of the original rate. That percentage will then be added to the original rate, along with the fixed fee.
The final rate will be calculated by the following formula:
Final rate = original rate + the percentage fee of the original rate + the fixed fee
Example calculation
The percentage fee has been set to 10% of the original fee, and the fixed fee is set as £3.
The original rate is set as £50.
Following the above formula, the final rate will be the original fee + the percentage fee + the fixed fee.
In this example, this will be £50 + (10% of £50) + £3 = £58.
