Sorry guys, I don't stock any boilers or milk cans. Those take up so much room, are so costly, and the customer (or distributor) always wants to customize them so they are always made to order.
Mostly I stock the stuff that takes a very long time to produce. If I can have it made in 3 or 4 weeks I don't usually need to inventory it. Some items can take 3 or 4 months to produce so I try to keep those in stock. SGKs, GB4s, ProCaps... stuff like that take a long time.
Tees, reducers, pipes, etc... usually need only 2 or 3 weeks to have almost any quantity made so I don't keep much of that on the shelf.
Oftentimes I face the minimum order, things like copper plates, perf plates, filter discs, etc... can only be produced in quantities of several hundred pieces so those items tend to grace the shelving for a long, long time. And when an item like that starts to finally run low I have to decide if its worth it to produce them again or to discontinue that item.
With over 400 items that we vend I'm always looking at culling the slow movers.
The little extra space that we'll gain with the new warehouse should take away some of the strain of keeping up with what we already have.
