## 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 =
SUMMARIZE(
FILTER(
'Sales',
'Sales'[Date] >= LastMonthStart && 'Sales'[Date] <= LastMonthEnd
),
'Sales'[Customer ID],
"TotalSales", SUM('Sales'[Sales Amount])
)
RETURN
COUNTROWS(
FILTER(
CustomerSales,
[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.

Thanks! That helps a lot!

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!
