See my most sold items

Hi - I sell a lot of spare parts - when my items stock reaches below 5 I increase the quantity back to 20. Is there a way where I can see what my most sold items are? I'd like to know so I can focus on those items. Currently I have over 850 items on my page so it's a bit difficult for me to see which items are my best sellers.

 

 

Regards
