Automated travel cost by postcode

Hi there, 

it is essential to my business that my form automatically adds a travel cost based on the address/postcode the client adds. The travel costs will be different for all areas.

Please help me find a solution to this. 

I did check your form and found that you have added products in Stripe payment tool of your form. The only possibility I can think of to achieve your requirement is by adding "Tax" in your payment tool. Please check the screenshot below:

Alternatively you can use normal form fields like radio button / checkbox question to list your products and condition to calculate the travel cost based on the address. You can then pass the calculated amount to the Stripe payment tool. The following guide should help you how to pass calculation to your payment tool:  https://www.jotform.com/help/275-How-to-Pass-a-Calculation-to-a-Payment-Field

Hope this helps.
