paypal have a service called "billmelater" which allow shopping for people who have no credit card. i wanna know that if i put a paypal checkout button on my checkout page , then customer can pay me with billmelater from paypal ?
Yeah you should be able to. When you create a paypal button for your site I am pretty sure it automatically sets so people can pay you without a card by default. I think you have to set the button to only accept credit cards. Look at the settings when you are creating a new button.
