You Do have the best clients!
This nice couple understands that my quote to them (can't remember what I wrote in their folder, and I don't think I saw CA at that time) is much higher than they had in the past. They came to me recommended by other clients with a very large invoice from me each year plus bills for the returns for their children, too. I don't expect any squawks from the newbies. Just very surprised at their prior preparer in NY. And, they want a projected 2018/paycheck check-up later, which I might invoice separately depending on what I end up charging for 2017. Plus, I'm warning everyone that my 2019 prices will increase due to the new tax laws.
Yes, we are lucky when our clients appreciate our constant education and know we are taking good care of them and willingly pay our fees. And, recommend us to others. When they don't, I raise their fees until they leave! But, have been lucky to NOT do that very often.
