On another board, a couple of years ago, one tax pro wrote in with his story: He'd always heard the "double their fee every year until you like them OR they go away" and decided to try it in his main PITA client. Bookkeeping, tax, tons of long-winded questions, the same mistakes every month - we all know the type. Was charging him $1,250/year. Doubled it to $2,500/year and they STILL drove him nuts. Doubled the next year to $5,000 and he still could not stand them. Doubled it *again* to $10,000 - and they are now some of his favorite clients! They pay on time, make the same mistakes and call with the same long-winded questions -- but now that he is getting compensated fairly, (as my older daughter says) "it's all shiny!" One key is the "paying on time" part. I doubt they would be his favorite clients if he had to hound them to pay his bills. Maybe, Sara, it's time to double their fee.
