Demand forecasting that accounts for supplier lead-time variance

Mid-market manufacturers typically run demand forecasts in Excel or a lightweight ERP module. The model works reasonably well when supplier lead times are stable. But lead times are not stable. A factory shutdown in a key region, a port backlog, a freight capacity squeeze: any of these can shift a 12-day lead time to 28 days in a matter of weeks. The forecast doesn't know, and neither does the planner until a shortage is already forming.

The problem is not that planners lack data. They have order history, they have supplier contacts, they have ERP reports. The problem is that the signals pointing to a lead-time shift are arriving through five different channels: a supplier email, a freight broker update, a port authority bulletin, a news item about weather. No one aggregates them into the forecast model. The planner is doing it manually, too late.

Supplyverde was built for this specific condition. The forecast engine pulls external risk signals and folds their lead-time implications into the reorder point calculation before the disruption reaches your shelf. When conditions shift, the forecast updates. The planner sees the revised number, not a stale one.
