Customers like using credit cards because they are fast and convenient. As a business owner, accepting credit cards means that customers can buy more or pay for more expensive services without having to finance them through your business. Instead, they finance it through their credit card and may accrue interest charges on their purchases.The fees you’ll pay to accept cards are usually the biggest drawback. A small percentage of each transaction might not seem like much, but it accumulates quickly. Cash, on the other hand, doesn’t cost you anything to accept.
