What sells while you wait for the order.
How this is calculated
- Days of cover = units in stock ÷ units sold per day.
- The stockout date is today plus those days. The order-by date subtracts your supplier lead time and your safety stock.
- This assumes a constant rate. It does not know your seasonality or the effect of a campaign, so raise the daily rate before a peak instead of using a monthly average.
- If the order-by date has already passed, you are late — which is exactly the signal Nuira turns into a recommendation to pause that product’s campaign.
