Many banks have checking accounts that charge you fees if you don't maintain a certain balance or some other criteria. Bank Of America Regular Business Checking Accounts allow you to avoid fees by using your debit card just once per month. I have about 10 different business accounts without reasonable opportunities to use any of them much less all of them.
I got a free credit card reader from Square and now I get a reminder from HassleMe approximately every 30 days which tells me to charge my debit cards. It takes me a few minutes and costs just a few pennies to charge a dollar to card and save myself $170 in fees each month.
