March Deduction Madness: Which Losses Are Winning?

March is when everybody starts talking brackets.

In supplier finance, though, the real tournament is happening in accounts receivable.

It is not flashy. It is not on TV. But it can absolutely wreck your season.

APQC treats adjustments and deductions as a core KPI area inside accounts receivable for consumer products companies, and its definitions make the point plainly: deductions can stem from freight and handling charges, discount terms, price discrepancies, and similar issues. In other words, this is not side noise. It is a real operating discipline with real cost. 

And the environment is not exactly getting easier. NRF says retailers expect returns to total $849.9 billion in 2025, equal to 15.8% of annual sales, with online returns estimated at 19.3% of online sales. When goods, promos, and payments get more complicated, supplier leakage tends to rise right alongside that complexity. 

So, in the spirit of March Madness, let’s build the bracket.

Not a scientific bracket. A practical one.

The kind supplier teams would recognize immediately.

No. 1 Seed: Post-audit deductions

If there is a top seed in this tournament, this is it.

Why? Post-audit deductions tend to show up late, feel murky, and land after the team has mentally moved on from the original sale. That is what makes them dangerous. They attack old revenue with fresh paperwork.

A promotion ran months ago. A freight term gets revisited. A compliance interpretation changes after the fact. Suddenly, someone on the supplier side is digging through old backup, trying to defend a margin that already looked booked.

That is why post-audit deductions deserve the No. 1 seed. They are sneaky. They are time-consuming. And they often hit when the organization is focused somewhere else.

No. 2 Seed: Promotional allowance errors

Promotions drive volume. They also create confusion.

Maybe the agreed funding amount does not match what the retailer deducted. Maybe the promo dates were interpreted differently. Maybe a display or feature did not run as planned. Maybe the deduction is technically tied to a valid event, but the amount is not.

This category stays dangerous because it looks familiar. Teams see promo-related deductions so often that they stop treating them like exceptions and start treating them like weather.

That is a mistake.

Routine deductions are still deductions.

And when promo calendars get crowded, the line between “planned spend” and “margin leak” gets fuzzy fast.

No. 3 Seed: Freight chargebacks

Freight issues have a nasty habit of multiplying.

A late shipment can create one problem. A routing miss can create another. A paperwork error can pile on top. Before long, one operational stumble becomes three financial hits.

That is part of why APQC’s examples matter. Freight and handling charges are right there in the definition set for adjustments and deductions. These are not fringe cases. They are part of how working capital gets strained in the real world. 

For suppliers, freight chargebacks are especially frustrating because they often start in operations but end in finance. The warehouse made the mistake. Transportation played a role. Customer service got involved. Then accounting gets the short pay and has to untangle the whole thing.

Classic cross-functional chaos.

No. 4 Seed: Markdowns

Markdowns are dangerous because they can feel justified.

The item underperformed. The store needed to clear space. The season moved on. The packaging changed. The retailer made a call.

Fine. But even when markdowns are operationally understandable, they still eat margin.

And if the root cause was avoidable, such as weak store execution, poor forecasting, delayed replenishment, or poor promotional alignment, the markdown is not just a retail event. It is a supplier lesson.

This is the deduction version of losing to a lower seed you should have beaten.

You saw the risk. You just did not act early enough.

Cinderella Team: Excessive defectives

This one does not always get top billing internally.

That is exactly why it is dangerous.

Excessive defectives often get dismissed as a quality issue, a returns issue, or a “someone else owns that” issue. But once the claims start stacking up, finance feels it, sales hears about it, and the customer relationship gets shakier.

That is what makes it the Cinderella team in this bracket. People underestimate it. Then it knocks out somebody important.

A fictional example: imagine a supplier launches a reformulated snack pouch. Sell-through is decent. The packaging looks sharp. Everyone is relieved. Then a slow trickle of defective-related claims starts showing up because seals are failing in transit. Nobody panics at first.

Three months later, the brand is dealing with credit issues, margin erosion, retailer frustration, and an internal debate over whether the issue is packaging, manufacturing, logistics, or all three. That is how Cinderella wins.

So who cuts down the nets?

If you ask most supplier teams which category hurts the most, the answer usually depends on what hit them last quarter.

If you ask which category is most consistently dangerous, I would still put post-audit deductions on top. They combine delay, complexity, and organizational fatigue in a way that is hard to beat.

But the real lesson is bigger than the bracket.

These losses do not operate alone.

Promo confusion can turn into post-audit exposure. Freight mistakes can trigger compliance issues. Defectives can become markdown pressure. Markdowns can create disputes over who should fund the clean-up.

That is why deduction recovery is never just about disputing claims one by one. It is about pattern recognition. It is about identifying which losses are recurring, which are valid, which are questionable, and which are quietly becoming part of your cost structure because nobody has had time to fight back.

And that is the part suppliers should not accept.

Because “cost of doing business” has a funny way of becoming “money we stopped trying to recover.”

Bad phrase. Expensive habit.

March Madness is fun when it is on the court. In accounts receivable, not so much.
