Identify new clients based on client ID and date

Hi everyone! I have a pretty complex problem that I have no idea how to tacke. 


So I have a customer ID column, a date column and a brand column. I have clients that have bought many times, but I also have clients that only bought once some time ago. 


I need to find out which clients are new. This is defined by those customer IDs that have only bought once in the last month. 


Any ideas on a meassure or column that could help me get that number? Ideally I should have that per brand also, but if it's too much, I can drive myself crazy thinking about that one later on.

Hello @pcda,


You can create a measure to count the number of customers that have bought only once in the last month:


New Customers = 
VAR LastMonthStart = EOMONTH(TODAY(), -1) + 1
VAR LastMonthEnd = EOMONTH(TODAY(), -1) + DAY(EOMONTH(TODAY(), -1))
VAR CustomerSales =
            'Sales'[Date] >= LastMonthStart && 'Sales'[Date] <= LastMonthEnd
        'Sales'[Customer ID],
        "TotalSales", SUM('Sales'[Sales Amount])
        [TotalSales] = MINX(CustomerSales, [TotalSales])


You can modify this to include the brand column by adding the brand column to the SUMMARIZE function and updating the filter accordingly.


Hope this helps you.

Do you know if there's any way to tie end and start of month to a dynamic slicer instead of to Today?


Thanks again! This was a great help!
