Sooner or later you are going to need to set up a way to receive payments (hopefully sooner rather than later).

If you are setting up an online store then you will need a shopping cart and payment processor, but when you are just starting out you are not going to need anything that complicated.

When I first started out on the internet I set up a free PayPal account to conduct business and I still use that same account today. I still recommend this service.

Several years ago I upgraded my ClickBank account to become a vendor and I still regularly use this account for sales and payments. I would recommend using ClickBank.

I have never purchased a shopping cart program as my web host and PayPal offer that option for free and the products I sell simply don't require that level of service.

I would suggest taking advantage of the free options I mentioned before investing any money in a shopping cart program.

I have from time to time experimented with other payment processors but I resented paying a monthly fee for services I could receive for free from PayPal and ClickBank so I have always returned to those as my primary payment processors.

I use both regularly as each provides benefits that the other does not and I find they work well together for me.
