Replenishment
Where a SKU has enough sales history, Stockful sizes its safety stock statistically - from how variable that SKU’s demand actually is and your target service level - rather than the flat day-buffer. The day-buffer above is the fallback for new or sparse SKUs.
Velocity calculation
Restock strategy
Low-stock threshold
The low-stock alert fires when a SKU is projected to run out within X days at its current sales velocity (default 7). Because it’s days-of-cover rather than a fixed unit count, the same threshold works for slow-movers and fast-movers without re-tuning per SKU.Units floor (for new SKUs)
Brand-new SKUs have no velocity history yet, so days-of-cover can’t be computed. For those, Stockful falls back to a units floor - alert when stock drops to or below this many units (default 5). The floor only matters until the SKU has accumulated enough sales history; after that, the days-of-cover comparison takes over automatically. Both settings live under Settings → Tracking.Settings hierarchy
When calculating forecasts, Stockful resolves each setting in order:- SKU override - if set on the variant, use it
- Supplier default - if the variant is linked to a supplier with a default lead time, use that
- Global default - the value from Settings → Forecasting
