What software would help me process credit card payments?
Have you looked into Square? It's a lightweight but strong option for accepting credit card payments.
If you're using QuickBooks, Intuit Payment Processing is also another option.
PayPal has mobile credit card processing as well: https://www.paypal.com/webapps...
I don't know if it's better than Square or Intuit, but if you already use PayPal, then it might be a good option.
