W9 Tax form & Wholesale Accounts

What should I know about filling and my W9 Tax form that I recently
filled out for Zale’s Corp? I am set up in the State of Nevada as
well. I just want to be clear on what taxes I need to clam when it
come to repair work, or custom work for another company who will be
collecting those taxes.
