Markdowns happen. Every retailer has them. Every supplier funds them at some point. The problem isn’t markdown funding. The problem is markdown drift—when price protection and markdown deductions creep beyond what was approved. Wider store lists. Longer windows. Wrong base costs. Caps ignored.

Defectives and unsaleables can quietly drain margin. Here’s a finance-first audit to spot duplicates, wrong rates, and out-of-window claims—fast.

Markdowns are one of those retail realities that everyone understands… until they hit your P&L in a way that doesn’t make sense. At the retailer level, markdown pressure is massive. Coresight estimates markdowns cost U.S. non-grocery retailers about $300B in revenue in 2018 (~12% of sales) , and attributes 53% of unplanned markdown costs to inventory misjudgments. That matters for suppliers because when retailers are fighting inventory and margin, they lean harder on mechani

Promotional allowances are supposed to be the controlled part of the retailer relationship. You plan the event.You fund the discount. You track the lift. And then… two months later… deductions show up that don’t match anything anyone remembers approving. That’s the moment trade spend stops feeling like growth investment and starts feeling like a slow leak.

You know the feeling: sales look healthy, shelves are full, and yet the cash line keeps getting nibbled to death by deductions. Excessive defectives are one of the sneakiest nibblers. Because it sounds like an operational issue—damaged goods, returns, reclamation, the messy stuff that happens after the sale. And yes, some of it is real. But a surprising amount of it is mis-coded, duplicated, out-of-window, or simply not yours to pay.

Markdowns feel simple in the store: price goes down, product sells through. But financially? Markdowns can turn into a messy conversation about who funds the margin gap—and whether the claim you received matches what you actually agreed to.

McKinsey reports that consumer packaged goods (CPG) companies invest about 20% of revenue in trade promotions, and that a large share of promotions fail to generate profit (their article cites research indicating 59% lost money globally and 72% in the United States). So when a promotional allowance is misapplied, duplicated, or “missing documentation” later appears as a deduction… it’s not a rounding error. It’s your margin getting billed twice.

If you’ve ever seen an “excessive defectives” fee and thought, Wait… since when are we paying a subscription for returns? — You’re not alone.

Retail compliance used to feel like a binder on a shelf. Now it’s more like a moving target—with three versions. A routing guide gets updated. A portal rule changes. Someone forwards an email amendment. Your third-party logistics provider (3PL) has a checklist that’s nearly identical. Meanwhile, your warehouse is just trying to ship clean, on time, every day.
