If they're accepting CCs, then they have a well established business. The fees that the card and processing companies charge can be quite outrageous, even if you have no transactions in a given month. If its something that would be worth it to you, definitely look into it! If you're a member of a wholesale club (like Costco or Sam's Club), sometimes they have deals for their members. Intuit also has a credit card service for small businesses. I only take cards via PayPal.
