As many of you know, I'm fortunate enough (old enough

) to not need any direct marketing. I just wait for the phone to ring

There are things that I've done though that helps to even out the work flow.
No matter how much marketing/advertising you carry out for the New Year, you are aiming at a vastly reduced marketplace, so it's less cost effective. After Christmas, New Year, the sales, holiday deposits etc. much of the residential market is "Spent Out", plus there is a tendency to wait 'till Spring when the mucky weather is gone. OK, reduced prices may be a lure in this climate, but I don't discount.
Over the years, I've tried with a great deal of success to manipulate my commercial clients to the January/February time. The returns are high but there can be cash flow hiccups. Fortunately that's not a problem for me. This releases more time in late November and December for the residential market when demand is exceptionally high. If there's a delay in Jan/Feb due to bad weather (rare) there's still reasonable capacity to re-schedule.
At all times during my 25 years in our industry, I've felt that to be working flat out all day every day is not good. This work cycle that I've developed works for me. Even during the quieter winter months, I earn enough from residential work to put meat on the table and when the cheques from the larger commercial jobs arrive, it goes straight into the building society to pay the Tax Man, Capital Purchases, Holidays etc.
As a (not particularly good) businessman, I've worked out that to give me the lifestyle I am comfortable with, I need to turnover £XX,000. It doesn't matter when during the year I achieve that figure. If I could earn it all in six months, I'd have six months holiday. If you adopt this approach for yourselves, you will be able to regard the slower times and holidays as just rewards for your efforts during the year, and not a time of poor/negligable returns.
Safe and happy holidays
