I went to a new shop to get my hair cut the other day. 

I won't be back.

I got a decent enough haircut.  I liked the person who cut my hair.  The environment was friendly, cheerful, and clean. It was even close to my home.

One big problem.  They take cash or check for payment only.

Really???  I rarely carry much cash and I don't even know where my checkbook is.  Last time I wrote a check was August 2009.  I do everything through online bill payment or....

Plastic.

If a business won't take credit and debit cards, it is extremely inconvenient for today's consumer.  Furthermore, as a healthcare provider, if you don't take cards, I have to do a bunch of paperwork to access my Flex Spending Account or my Health Savings Account.  I don't want to do that.

I've heard the argument from chiropractors who don't take cards.  It is a hassle and the processing services cost money.  I would argue that it will cost you more in the patients you lose.

Your practice is patient-centric in all other respects.  How your patient pays should be as well.
