Start with lead time
A supplier that takes 30 days to deliver needs a different reorder trigger from one that replenishes in three days.
Consider sales velocity
Fast-moving SKUs should reach the reorder point earlier than slow-moving products.
Account for reserved stock
Available-to-sell stock may be lower than physical stock when open orders have already reserved units.
Plan by location
A company can have enough stock overall while one warehouse is close to stock-out.
Review seasonality and campaigns
Promotions and seasonal demand can make historical averages misleading.
Use recommendations as decisions, not autopilot
Forecasts should help buyers prioritize review while preserving human approval for purchase commitments.
The operating principle
Every event should remain connected to the product, contact or transaction that created it. That is what lets ERP explain a number instead of only displaying it.
