[SOLVED] Counting Names in different sales years.

[baca25]

I need to count the names of the Companies in each year, if they had sales.
If you hard count them for example, in 2012 there were 5 companies that had sales, while in 2013 there were 4(because DD had no sales). The "ship to" does not matter, but it is there.
So, How do I do that?
Thanks for the help, this is something for work.
