Managing online payments efficiently is crucial, especially in industries like automotive where transparency is key. With our website's form integrated with Machform, clients can conveniently pay using Paypal or Stripe. Now, regarding your query about adding a service fee field in Machform, it's definitely possible. This feature ensures that the user-entered amount includes any applicable fees, such as a charge card processing fee. For instance, if a customer is paying for a used car priced at $100.00, Machform can automatically calculate the service fee of $3.20 (inclusive of a charge card processing fee of $0.30 plus 2.9% of the invoice amount), resulting in a total amount to pay of $103.20. This streamlined process not only enhances user experience but also provides a clear breakdown of costs related to the used car (https://www.priceusedcar.com/) purchase.
