Frequently asked questions
How do I forecast sales?
A baseline, a growth rate and a seasonal profile. The seasonal profile matters more than the growth rate for planning purposes, because it determines the peaks.
How do I build a seasonal profile?
From your own history, each month as a share of the annual total. Two or three years of data is enough to see the pattern; one year is a guess.
Should I forecast conservatively?
For cash, yes. For stock, forecasting low causes stockouts in the peak, which is usually the more expensive error. Two forecasts serving different decisions is not inconsistent.
How far ahead should I forecast?
Far enough to cover your lead time plus the selling season. For imported goods with a ten-week lead time, that means committing to peak stock five months ahead.
