One of the most important services being promoted for merchants today is that of credit card services. If you want a lot of sales, then you have to accept credit and debit cards or you will lose a lot of your business to the guy across town who does take them. So, once you get established, it’s time to do your homework and see exactly how much each company will charge, because just like you and your competitors, there are wide differences among you.
You can find a lot of information on the web that will lead you to the exact information that you should look for. For instance, what percentage of the sale does each company charge, and what extra fees are there? Service doesn’t come for free, but as they say, it’s worth what you pay for it.
