With your own merchant account you must pay for expensive processing software, a secure server, customer service fees, monthly gateway fees or minimum transaction fees.

But there is solution to accept credit cards online without merchant account or with so-called free merchant account.These free merchant accounts are provided by third party credit card processors that accept credit cards on your behalf and take a percentage of the cost of the transaction. This percentage is relatively higher than it would be if you had your own merchant account, but you only pay fees if you sell your product. There are usually no monthly fees.

It is also the simplest solution - sign up with a third party processor, insert several lines of HTML code, and that's it! The service provider will take care of the rest.

Online credit card processing companies will send you payment for all of your orders processed, minus their fee and a reserve fee. A reserve fee is withheld to cover charge backs you may have. If you have no charge backs within a period of time, your reserve will be refunded to you.

An excellent feature, many of these credit card processors offer is a build-in affiliate program for your own online business.

Third party credit card processors are the best option for small and just starting businesses, as well as for international (non-US) businesses where obtaining your own merchant account is too expensive or hard to get.

Third party credit card processors are cheaper as long as your total sales are low. When your monthly sales reach around $3000, you should consider to open your own merchant account.
