SKU Rationalization: How to Decide Which Products to Cut

Every shelf, showroom and warehouse has a long tail of products that quietly drain money — slow movers that tie up cash, block space and complicate ordering. SKU rationalization is the disciplined process of deciding which items to keep, cut or expand. Done well, it frees working capital and lifts margin without hurting sales. Done on gut feel, it drives customers to competitors.

What is SKU rationalization?

SKU rationalization is a periodic review of your assortment where every item is scored on how much value it actually creates — not how long it's been on the shelf. The goal isn't to cut for the sake of cutting; it's to reallocate space and cash toward products that earn it.

Step 1 — Pull the four metrics that matter

Before you judge a single product, gather these per-SKU numbers from your POS and inventory system:

• •Sales velocity — units sold per week. Separates genuine movers from shelf-warmers.
• •Gross / contribution margin — profit per unit after landed cost, not list price.
• •Inventory turns & weeks-of-supply — how long capital sits trapped in each item.
• •Stockouts & carrying cost — lost sales on one end, storage/handling cost on the other.

Step 2 — Plot velocity against margin

Map every product on a simple 2x2: velocity on one axis, margin on the other. Four groups fall out:

• •Stars (high velocity, high margin) — protect and expand facings.
• •Traffic drivers (high velocity, low margin) — keep, but look for margin fixes.
• •Niche earners (low velocity, high margin) — keep selectively where space allows.
• •Dogs (low velocity, low margin) — your rationalization candidates.

Step 3 — Check the strategic role before you cut

A low-performing item on paper can still earn its place. Ask three questions before delisting any 'Dog':

1. Is it a basket builder that pulls high-margin items into the cart?
2. Is it a loss leader that drives foot traffic or visits?
3. Is it a defensive SKU that stops customers switching stores to find it?

The most expensive mistake in assortment isn't keeping a slow mover — it's cutting the one product a loyal customer came in for.

Step 4 — Exit gracefully, recover the cash

Don't just switch items off. Bundle slow movers with stars, run progressive markdowns (e.g. 30% then 50% then clear), or move excess through opaque channels so you recover capital without devaluing your brand.

Step 5 — Make it a habit, not a fire drill

Adopt a one-in, one-out rule for new products and review the portfolio every quarter. Better still, let software flag velocity and margin anomalies automatically so problems surface before they become dead stock.
