Good to see you posting Jim! That is a pretty huge install. Congratulations!!
You probably know that the written area is what takes priority because it's really easy to alter the numbers. The amount of my check was small, $85.08, and I brought a copy of my invoice that matched the invoice number written in the memo portion of the check. I think that because it said "Gesner" on it that was good enough for them. I'm sure it helps that they know me well there too. I've had a personal accounts there longer than any of the employees have been working there and I've had my business account there since 2002.
