Using SSRS, you could generate multiple groupings fairly easily and display all of this information at-a-glance.

In a vanilla T-SQL query, you can do it like this:

SELECT
    YEAR(s.[date upgraded]),
    s.[user],
    COUNT(*) AS [total upgrades]
FROM [Sales] s
WHERE s.[upgrade] = 'yes'
GROUP BY s.[user], YEAR(s.[date upgraded]) WITH ROLLUP
ORDER BY YEAR(s.[date upgraded]), s.[user]

SELECT
    MONTH(s.[date upgraded]),
    s.[user],
    COUNT(*) AS [total upgrades]
FROM [Sales] s
WHERE s.[upgrade] = 'yes'
GROUP BY s.[user], MONTH(s.[date upgraded]) WITH ROLLUP
ORDER BY MONTH(s.[date upgraded]), s.[user]
