I'm looking for a magento 2 solution for my donation site where the users can add any amount and donate meaning checking out with custom pricing and order placement and other flow should work as it is. They should be able to download the invoice from their my account from the frontend, just that the pricing can be any number greater than 0
To satisfy your requirement to accept donation on your website, use our Magento 2 Custom Price extension with which you can create products with the editable price to accept payments for custom products, donation or charity.
Enable custom price for the required product and set minimum price allowed so that users cannot enter price less than set minimum price for the donation.
