Hey Gary...what part of the biz is it he/she doesn't understand?
Maybe you got to sit down with them and go over some things with them...educate 'em if ya know what I mean. That's what I did with mine. And, not all at once...over a year maybe.
In fact, when it came to the Chart of Accounts that I use with my QuickBooks program, I told them the way I was going to set it up, not vice versa. Since I use it everyday, and they only use once a month, I had the upper hand.
Plus, I'm the one flippin' the bill.
