One other thing I'd like to add to this conversation...If you're not taking credit cards (especially a mobile solution like Square) you're not doing yourself any favors.

From that, you're really not doing yourself any favors if you don't let your clients know that you take credit cards in your initial phone call.

You'll be shocked at how many customers may not have the immediate money in the bank, but they're willing to put it on a card.  It will increase your sales, it will also increase the amount of your sales.

When I started doing Square, I thought it would be a addition, and just make transactions a little easier for the "every once in awhile" client.

Last year I did just over 150k on Square.
