Bars show the after figure as a share of the before figure — shorter is better. Every row is pulled from Northwind's TMS and billing ledger, not from our own telemetry.

Two branches still run a manual accessorial log and are excluded from the figures.

“We never had a disputes problem. We had a problem where nobody could see the weight ticket and the invoice at the same time.”

What was happening

Northwind bills freight on weight, distance and accessorials — detention, liftgate, inside delivery, redelivery. The accessorials arrived as paper tickets, keyed in at the branch, and the invoice went out before anyone had compared the ticket to the rate confirmation. One invoice in five came back disputed.

A dispute cost 22 minutes of a billing clerk's time and, far worse, stopped the clock on the whole invoice. Average days sales outstanding sat at 61, against a target of 45, and finance was writing off roughly $310,000 a year in accessorials nobody could evidence by the time the customer pushed back.

What changed

A pre-bill audit now matches three documents — rate confirmation, weight ticket and accessorial log — before an invoice is released, and holds anything that disagrees by more than $25 or 200 lb. Held invoices go to a queue with the three documents side by side. It reads the existing TMS feed; nothing about the rating engine changed.

Three branches went live on 9 March. All twenty-two were live by 17 April.

What it cost, honestly

Six weeks from kickoff to the first live branch, most of it spent on one integration to a TMS export that turned out to round weights to the nearest 50 lb.

The first fortnight was bad. The hold threshold shipped at $10, which held 31% of all invoices and made the queue worse than the disputes had been. Raising it to $25 on 23 March dropped holds to 7% and is the single change that made the numbers above possible.

“The first month I kept refreshing the dispute queue because I assumed it was broken.”
Devon Marsh, Billing Supervisor, Northwind Freight
