This client is in 2014. I believe the restriction of letters was loosened a few version ago, like you, I thought this was not an option. They are using the wiring function now. The person that decided he did not need to attend the provided training on the product during last months implementation was just doing what he always did in QuickBooks. (That is, when he was not using his other method of repeatedly using the check number of ""1"" because it was easier to enter that way.) This kind of accounting took away the sting of embarrassment a bit on my part.
