1 – user A post a project of 30 days 1 thousand dollars
2 – 3 users, B, C and D donated 100 each to project until the end of 30 days.
So at the end of 30 days, the project have 300 dollars funded 700 Miss. So we cancel the project.
3 – If we are using refund or normal paypal payment. Paypal would charge us FEES 20 dollars. So I had to give money back to users and loose 20 dolllars at the end,
4 – We need paypal to froze the money until the end of project. If not go threw paypal do not charge users, so they no need refund and we do not pay fess. This is call PRE APROVAL PAYMENTE
1 – User post a project – 60 days 2 thousand dollars
2 – Users B, C, D, donates 50 dollars each, users E,F,G,H,I Donates 200 Dollars each, and user X donate 900 dollars.
3 – After 60 days we raised the 2 thousand dollars amount, SO PAYPAL CHARGES ALL USERS all the amounts that they donated. I DON'T NEED TO DO NOTHING to get the money on my paypal account. Money of all the users will come to my account after 60 days that Project is funded
