SKU Rationalization on Amazon: What to Cut, Pause or Fix

Adding SKUs feels like growth, and removing them feels like a step back. But every product on your account claims cash, storage space, ad budget, review attention and time, whether or not it earns its place. A catalog that has grown by habit usually carries a tail of items that sell slowly, depend on ads to move at all, or quietly damage the brand's average rating. This article sets out a simple way to score each SKU, choose between cutting, pausing and fixing, and deal with the stock you already own.

Why a smaller catalog can earn more

A weak SKU costs more than its own losses. It spreads ad spend across more targets, so the products that deserve budget get less of it. It splits reviews and attention that could build a stronger anchor product. Its inventory ties up cash that could fund a reorder of something that sells, and it adds storage cost while it waits. If it has poor ratings or a high return rate, it also shapes how shoppers see everything else you sell.

None of this means smaller is always better. A SKU can look weak on a short window and be a healthy seasonal product, or be a launch that has not matured. The point is to make each SKU justify itself with evidence, using consistent measures, rather than keeping it by default.

The five measures

Contribution margin

Start with what a unit leaves behind after landed cost, Amazon fees, returns and ad spend. Look at both the per-unit amount and the monthly total in dollars. A SKU with a rich margin that sells five a month contributes less than one with a thin margin that sells five hundred.

Velocity

Measure units sold per week and the direction over the last few months. Convert it to days of cover: units on hand divided by average daily sales. If cover is far longer than your supplier lead time plus a safety buffer, you are carrying more of the SKU than demand supports.

Ad dependence

Ask what happens to the SKU if you turn ads down. Compare ad spend to sales for the SKU, and look at how much of its volume is ad-attributed. A SKU that sells only when it is advertised is not automatically bad, since it may still be profitable after ad costs, but it is fragile and expensive to keep alive.

Carrying cost

Holding stock costs more than the storage line on a report. It also costs the return you could have earned on the cash, plus the risk that long-held stock attracts extra charges as it ages. A rough per-unit, per-month figure is enough to compare SKUs.

Review risk

Check the star rating and its recent trend, the return rate, and whether the complaints point at the product itself. A low-rated SKU inside a variation family, or one that draws frequent returns, can hurt neighbors that are otherwise healthy.

Score each SKU and set the bands in advance

Pull the inputs into one sheet with a row per SKU: sales and traffic by item from your business reports, advertising spend by product from the ad console, on-hand units from your inventory reports, and return rates and ratings from your returns and customer feedback views. Use at least a full quarter of data, and for seasonal products compare the same season in the previous year instead of the last few weeks.

Give every SKU a score of 0, 1 or 2 on each of the five measures, where 2 is clearly healthy, 1 is borderline and 0 is below your minimum. You set what those mean from your own economics, for example a margin target for a 2 and a floor for a 0. The totals range from 0 to 10. Decide the bands before you look at the results, so you are not tempted to bend them toward your favorite products:

• 8–10: keep and grow.
• 5–7: fix.
• 3–4: pause.
• 0–2: cut.

Three overrides sit above the score. A SKU that is losing money on every unit after ad spend is a cut or a fix now, whatever else it scores. A safety, compliance or serious quality concern means pause immediately. And a SKU inside its launch period is judged on a separate track against its launch plan, not against mature products.

Cut, pause or fix

Pause and cut look similar from the outside, but they lead to different actions. A pause is a decision to wait. A cut is a decision to leave.

A fix is for a SKU with a clear, specific reason it scores low and a reasonable chance of correcting it. Common fixes are raising the price or lowering the cost, renegotiating the order quantity, improving the listing, changing the ad structure, redesigning a weak component, or bundling it with a stronger product. Give each fix a short deadline, such as one review cycle, and move the SKU to cut or pause if the numbers do not improve.

Before you cut, check whether the SKU feeds the rest of the range. It may be a low-priced entry point, or a variation that completes a family. If Brand Analytics is available to you, its repeat purchase and items bought together reports can show whether shoppers who buy a weak SKU go on to buy a strong one.

What to do with the stock

The money you spent on the inventory is already gone. Decide from what you can still recover and what holding it will cost from here. Compare the options on a per-unit basis: selling it down with price promotions or break-even ads, pairing it with a stronger product, removing it and selling elsewhere, using an Amazon liquidation program or an outside liquidator, or donating it if you are eligible. Fees, eligibility and terms change, so check the current conditions in Seller Central before you choose.

A quick test uses days of cover. Suppose you hold 600 units that sell 30 a month. That is 20 months of cover, and at $0.25 per unit per month the last units in line carry about $5.00 each in holding cost before they sell. If a markdown today recovers more than waiting would, after fees, the markdown wins. If you ever see aged-stock charges on the SKU, include them, because they change the answer.

The short version

• Score each SKU 0 to 2 on margin, velocity, ad dependence, carrying cost and review risk.
• Set the action bands before you see the results, and respect the three overrides.
• Pause to wait, cut to leave, fix when there is a specific, dated plan.
• Check whether a weak SKU feeds a strong one before you remove it.
• Decide on stock using recovery value and holding cost, and revisit the scorecard each quarter.
