How to improve COD delivery rates

What is "delivery rate" actually measuring?

The share of shipped parcels that reach the customer and get paid for at the door, as opposed to coming back to you as a return of some kind. It is a downstream number by nature: it reflects everything that happened before the parcel was ever created and handed to a carrier, not just what happens during the delivery attempt itself in isolation from everything preceding it. A store trying to improve delivery rate by pressuring the carrier alone, pushing them to try harder or attempt more times, is working on the smallest lever actually available to it, because most of what determines whether a parcel gets delivered was already decided long before the carrier ever touched that specific parcel.

Where does the biggest improvement usually come from?

Confirmation discipline, applied without exception regardless of how busy the day gets or how tempting it is to skip the step just once. Parcels shipped without a written customer agreement carry a meaningfully higher return rate than confirmed ones do, because some share of them were never real commitments to begin with, no matter how the order looked on the surface when it first arrived. Moving from "ship everything, deal with returns after the fact" to "ship only what is confirmed in writing, no exceptions ever" is usually the single change that moves delivery rate the most across an entire store's order volume, and it is also the cheapest change to implement of anything on this list: it costs process discipline, not new tooling or additional carrier fees paid out each month.

What comes after confirmation discipline is in place?

Address and phone quality, collected at the moment confirmation happens rather than fixed reactively after a failed attempt has already occurred and cost real money. Once every shipped order has a real commitment behind it, the remaining failures are mostly logistics in nature: the driver could not reach the customer by phone, or could not find the door on the address given at intake. A second phone number and a specific address detail, both collected at confirmation time rather than after the fact, close most of what is left in this category and turn what was a reactive fix into a preventive one built into the process itself.

What is the actual order of priority?

Working this list in the order given matters more than it might seem at first glance, because fixing item 3 or 4 while item 1 is still loose barely moves the overall number in any noticeable way: shipping speed does not help an order that was never a real commitment in the first place, regardless of how quickly it ships afterward once created.

How do you know the changes are actually working?

Track delivery rate on confirmed orders specifically, kept separate from delivery rate on all shipped orders combined together in one figure. If you have removed unconfirmed shipping entirely from your process, these two numbers converge over time as the population of shipped orders changes, and confirmed-order delivery rate becomes the number that reflects address and shipping-speed quality cleanly, without commitment failures muddying the read and making genuine improvement harder to see clearly week over week. Watch that number weekly for the first month after each change, since a single week of data is usually too small a sample at typical volumes to reliably tell a real shift apart from ordinary variation.
