Choose an experienced merchant selling credit card processing services company. Select several companies and evaluate each one. Do they fit all of your needs? Check their customer service reviews. Make sure you understand their fees and other charges. Are they comparable to other companies? Once you've narrowed your choices, select three that you like the best and that offer everything you are looking for.

Who owns the company? Is he or she available to talk to? Check their social media. You can tell a lot about a business by their social media engagements. Would you be proud to call that company or the owner your friend? Not everything on a social media necessarily points to the character of a business owner, but you can often determine if friendliness and honesty carries throughout that person's business and social life. Many large companies use social media before hiring new employees. But, that is an option that is up to you.

You can also ask about their other satisfied clients. If you plan to be one, it's a good idea to find out what others are saying. Check the local Chamber of commerce, Google reviews and the BBB, three great resources.
