Pay It Square

With Pay It Square, you use a Collect Page to organize and track payments you're collecting.  You notify your friends, donors and attendees that you are collecting for a group payment, fundraiser or an event registration. Your friends, donors or attendees use credit cards, bank accounts, or PayPal balances to make their payment online - easier for them and more certain for you.  You can always track who's paid and who hasn't - even if they pay you offline.

Built on PayPal.  Cheaper fees than competitors.
