Not doing updates on last working day of the month

I notice that you are doing an update on 28 February. Many small businesses work strange hours - what larger businesses who have multiple staff would class as out of business hours. On the last working day of each month, most businesses send out statements. With small businesses these are done probably out of normal business hours. To be told that you are installing an update just at the time that we would be doing this work is most inconvenient. Yes there are work arounds but it just complicates matters.
