I am getting some positive indications on a bid for an HOA. I am comfortable with my bid in terms of total amount. In an effort to be consistent with other bids I took the total amount and divided it up into monthly amounts. I am being asked via email, if I intend to bill monthly, that amount. Its not clear to me the point of the question. What is the norm? A month in advance? 2 months? I'm sure in the rears is to be avoided.. please advise.
