Frequently asked questions
What if a product has no supplier mapped?
Add an IF node that routes unmapped SKUs to an internal alert so you can add the supplier before stock issues recur.
Can I set reorder points above zero?
Yes — trigger on a low-stock threshold like 5 units instead of zero so you reorder before fully selling out.
