I keep vent screens, corners, tp pins and locks, a few tp dispensers and urinals in stock along with the aforementioned items. Sometimes if I have a unit with a wall or two damaged, rather than fix it, I’ll part it out so I have an extra skid, tank, roof, etc. on hand.
I started with 3. By the end of the first year I had over 80. We were lucky to be able to purchase units as we needed.
On a related note, I would highly encourage you to read the article on this site about branding. It’s very good. As a startup you will want to make yourself memorable. Having a great logo and everything look the same will help that. Great customer service will help too!
Good luck with your new venture!
