After searching the previous threads I was not able to find the answer to this question: When should renewal letters/contracts go out? Should they go out now, as the season comes to an end, or wait until very early spring? Just an FYI, I am not planning any price increases and all of my customers claim to be happy with the service I provide and have already commented on next season. Thanks for the advice, Mark PS. I am going to include a clause that relates to an increased fee should local fuel prices go above $2 again.
