A reorder point is a pair of numbers you set on an item: the least you want to have, and the most.
Setting | What it means |
Minimum | When stock drops below this, it is time to buy more |
Maximum | How much you want back on the shelf when you do |
The minimum decides whether to order. The maximum decides how much.
Example
Inner tubes: minimum 250, maximum 500.
You are down to 240. That is below the minimum, so tubes appear on your reorder report with a
suggestion to buy 260 — enough to get back to 500.
Setting both to zero is a real choice
Zero minimum and zero maximum does not mean "not set up". It means hold no stock of this — you buy it only when someone orders it.
An item on a zero policy still appears on the reorder report if you have sold more than you have, so you can order enough to get back to zero. That is correct, not a glitch.
What counts as "stock I have"
The report looks at what is available, and it subtracts what is already on the way. If you are below your minimum but have a purchase order arriving that covers it, the item does not appear — you have already dealt with it.
