Why safety stock matters for merchants in France
Cross-border logistics, customs and last-mile operations in France introduce lead-time variability that pure rule-of-thumb formulas under-estimate. Using a service-level approach lets you size the buffer statistically, per SKU. Combine this tool with the reorder point calculator for France to get both the buffer size and the trigger level.
