Most companies keep a day by day chart along with a cumulative month to date total. Plus they know what their daily average should be and can compare February to date’s average with that.
Usually they also compare their current February sales to this date figures with last years.
You do not wait until the month is complete to look at your sales. You keep track each day and use this to schedule advertising and sales (The one where you cut prices to try and drive up actual sales. That is confusing by using sales (as in running a sale) and sales (as in the amount you sold)in the same sentence.)
Okay, thanks for the information.
