Start with the decision

How many days early or late was each delivery against its stated duration?

Small sellers reviewing completed supplier deliveries.

From input to next step.

  1. 01

    Define the start event

    Choose order acceptance, payment or another actual agreed start. Use calendar or working days consistently; this file does not calculate a working-day calendar.

  2. 02

    Reconcile the duration

    Enter stated and actual lead days from the same event basis. Keep transit and production definitions consistent.

  3. 03

    Review the difference

    Investigate delays and retained evidence before changing ordering assumptions. Historical timing does not guarantee the next delivery.

A look inside

The example, in plain sight.

Fictional values from the workbook. Amounts are illustrative currency units, not a market rate or a customer result.

Before you use the result.

  • Do not mix dispatch and receipt dates.
  • A negative difference means earlier than the stated duration.
  • Actual supplier terms remain separate.

A delivery-duration review, not supplier monitoring or delivery prediction.
