I am starting my own online business and need to accept credit cards. I have looked at the services that paypal web payments standard have and like them. However i need to know if i have to have a merchant account or can i just use my own/business’s account ?
No. That is what Paypal is all about. They act as your credit card processor. Just be sure and get setup well in advance of your first transaction as it takes a number of days to get setup due to bank verifications for your account for deposits.
