Forms are a versatile tool on the web, allowing users to build anything they want with minimal effort. To accept payments in a form, all you need is a form and a payment processing service. You can use a form builder to create forms that gather customer information and accept payments, or use a payment provider's built-in form builder to make forms specifically for payments. There are many options available for form builders with payment processing services, including PayPal, Stripe, Braintree, and more. Additionally, you can use PayPal's Buy Now button to accept payments from forms that don't have a direct payment feature. With the right tools and knowledge, building effective forms is not as difficult as it may seem.
