Payment form: allowing the user to enter amount

Hi, sorry my bad English.
Before buying "payement form" i want to be sure that i can create a form where the user can also enter the amount to be paid. I would like to offer my customers able to make online payment of fees. They should be able to connect to the site, fill out a form with the data of the parcel received including the variable amount to be paid, then make the payment. It's possible? From the examples i have always seen that the amount is predetermined.
Thank's!

Hi

Yes. It is possible. You will just simply need to enable amount field for the form you created. Then when customer access to the form, they can enter the amount they want to pay to process payment !
