SharePoint List linking

Good Morning Everyone,

I am brand new to this so please forgive me if my question is too basic.

I am new to Sharepoint and am trying to set up a system that controls stock coming in and out of one of our yards. I thought that the best way would be in the form of a list logging the items in and out. I would then like a master list to link to the In/Out items with a running total of the items. Is this possible?

Thank you in advance.
