Here you go:

SELECT	T.Month,
		T.SALES_GROUP,
		T.SALES_NUMBER,
		SUM(T.[Net Product Sales])
FROM	@table1 AS T 
GROUP	BY T.Month,
		T.SALES_GROUP,
		T.SALES_NUMBER
--Uncomment this for particular ordering
--ORDER	BY T.Month DESC;

There is no customer column in your test data and that query matches your expected output. Do you have an example of this customer data and what the new expected would be?
