How do sellers get paid online?

If I'm setting up a system where people can sell stuff online. I'm planning on having my own merchant account and setting up my own payment system.

The problem I ran into is how to I send money from my merchant account to others. The only thing I have used so far is paypal to receive money, what other ways are there to receive money online? Can people use their local bank accounts? Savings accounts? Should I worry that my merchant gateway API wont support certain banks? Am I going to need to store my user's bank account information?

There are three ways you might want to consider, and possibly use them all.

• Paypal and similar systems
• Credit Cards -- you can transfer money both into and out of credit and debit card accounts. Paypal can handle this if you have trouble setting up your own credit card accounts.
• Direct Bank Transfers -- transfer money into or out of someone's bank account, similar to a direct deposit or a monthly payment.

If you use Paypal only, you won't need to store the customer's financial info. This releases you from a lot of security worries and liability. You can also avoid storing the customer data by making them re-enter it every time, but this goes against the philosophy of satisfying the customer.
