The short answerCOD delivery rate measures successful delivery within a defined eligible population. State whether the denominator is dispatched orders, resolved attempts or all created orders. These measures answer different questions. Use mature outcomes and keep pending orders visible instead of treating them as completed failures.

Define the status model

Write what counts as dispatched, delivered, refused, returned, cancelled and pending. Courier and store status labels may not have identical meanings. Reconcile material differences before using the rate to judge campaigns or regions.

Also specify whether collection is part of the completed business outcome. Delivery and cash reconciliation can occur at different times.

Calculate the rate

  1. Select a cohort using a clear dispatch or order-start date.
  2. Allow the relevant observation window to complete.
  3. Count eligible delivered outcomes.
  4. Divide by the stated denominator.
  5. Report pending and other statuses separately where needed.

Do not silently change the denominator between reports. A rate based on resolved attempts can look higher than one based on all dispatched orders still awaiting outcomes.

Worked example: two distinct questions

Illustrative example: 120 orders are created, 80 are dispatched and 60 are delivered after the defined window. Delivered share of dispatched orders is 60 / 80 = 75%. End-to-end delivered share of created orders is 60 / 120 = 50%.

Both can be useful. The first inspects fulfillment progression; the second includes losses before dispatch. Neither should be presented without its definition.

Put this into practice

Add the denominator, cohort date and pending count to the delivery report. Recheck any campaign decision previously made from a rate whose definition was unclear.
