The low-volume SKU never sold. It still cost you slot and shelf.
Every food and beverage range carries SKUs that earn their slot and SKUs that quietly tax it. Low-volume lines, perishable items and novelties consume picking time, chilled storage and shelf space out of all proportion to the cases they move, and a product report that stops at gross margin never charges them for any of it. SKU rationalization without true cost is guesswork; with TDABC it is arithmetic.

SKU profitability in food and beverage depends on handling, storage and spoilage, not just gross margin. Low-volume, perishable and novelty SKUs consume picking time, chilled slots and shelf space disproportionately, and perishables add spoilage and out-of-code returns. TDABC assigns those costs per SKU, so rationalization decisions rest on true margin instead of volume or gut feel.
Adding feels like growth. Removing feels like loss.
The range tends to grow in one direction only. Every promotion, every customer request, every seasonal idea adds a SKU, and very few are ever removed, because removing one feels like a loss and adding one feels like growth. Over years this produces a long tail of slow movers that each look harmless on a gross-margin line yet together consume a large share of warehouse, chilled and shelf capacity. The cost of that tail is real but diffuse, spread so thinly across the catalogue that no single product ever looks like the problem. True per-SKU costing pulls the diffuse cost back to the products that cause it, and the range can be managed as a portfolio with a budget rather than as a collection of individually defensible decisions.
SKU proliferation eats capacity
Each extra SKU needs a slot, a pick face and shelf space. Many low-volume SKUs together absorb a large share of warehouse capacity for a small share of volume.
Perishability is a cost, not a footnote
Short shelf life drives spoilage, markdowns and out-of-code returns. A perishable SKU with a healthy gross margin can be a net loss after waste.
Chilled SKUs cost more to hold
Refrigerated slots are more expensive than ambient ones, and a flat allocation hands the chilled SKU the same overhead as the dry one.
Novelty lines rarely repay their slot
They look exciting and move little. Fully costed, many never repaid the slot, pick time and shelf they consumed.
THE RANGE: A LONG TAIL THAT TAXES CAPACITY
Illustrative. A few SKUs move most of the volume; a long tail moves little but consumes slots, pick time and chilled space the gross-margin line never charges them for.
Handling, slot, spoilage and returns, per SKU.
A SKU's cost is more than its cost of goods. It is the pick time per case, the slot it holds each day, the chilled premium if it is refrigerated, the spoilage on what ages out, and the handling of what comes back out of code. Load all of it and the slow, perishable, chilled line stops hiding behind a healthy gross margin.
SKU handling cost = pick time per case x cases moved + slot cost per day x days held + (chilled slot premium if refrigerated) + spoilage rate x unit cost + out-of-code return handling x returned units
Illustrative. The spoilage and return terms are where a perishable SKU with a healthy gross margin turns into a net loss.
Freed capacity is not abstract.
As an illustrative sector pattern, a producer found that a set of novelty and low-volume lines it assumed were fine were far less profitable than believed once chilled storage, pick time and spoilage were assigned to them. Rationalising the worst offenders freed chilled slots and pick capacity for the lines that actually paid, and the gross-margin report that had protected those novelties turned out to have been the problem all along. The point is not a blanket cull. Some low-volume SKUs earn their slot because they anchor a key account that buys profitable volume alongside them, or hold a shelf position a competitor wants. True per-SKU cost separates those from the ones that exist only because nobody ever measured them. A chilled slot released from a dead novelty is a slot available for a fast-moving line that was being turned away, and pick time saved on a SKU nobody buys is pick time returned to the orders that drive the business.
Frequently asked questions
- How do you measure SKU profitability in food and beverage?
- Load pick time, slot cost, chilled premium, spoilage and return handling onto each SKU with time equations, then compare to net contribution. Gross margin alone overstates low-volume and perishable lines.
- Should I cut low-volume SKUs?
- Only after costing them. Some low-volume SKUs anchor a key account or category; others simply tax capacity. TDABC tells you which is which.
- Why are perishable SKUs often unprofitable?
- Short shelf life drives spoilage, markdowns and out-of-code returns that gross margin never captures, and chilled storage costs more than ambient.
