Hello, I'm working on a payment process that requires a large variation of possible prices, so many that it makes creating different products and variants too difficult to manage. Each customer receives a contract with a calculated price prior to coming to the page to make a payment. What we are looking for is the ability to allow the customer to enter the price directly as stated in the contract - similar to a donation block - then pass that information to the paypal integration for payment. We considered using the donation bock, but that has tax implication and forces, or so it seems, donation verbiage into the process which can cause confusion. Any help is greatly appreciated. Thank you!
