Sudden Drop in Sales at the Beginning of Each Month

Welcome to sales.  Some days UP, some days DOWN.  It all averages out at the end of the year.

Don’t sweat the small stuff. 

It is not unusual for sales to vary day by day, and it doesn’t mean that there’s any problem with your account, other than the fact that no Buyers are selecting your images. If the first of the month falls on weekend, when sales are usually low, that would explain the trend you’re seeing.  

I suspect a number of contributors see patterns (real or imagined) when it comes to sales. Me, my sales generally occur first thing in the morning and there are few if any thereafter. On weekends, nothing sells in the morning but I might sell one or two late in the evening. Maybe it has something to do with the type of assets one sells and how they correlate with demand with respect to the time of day, the days of the month, seasonal changes...who can say?
