How much stock should a merchant business hold?

A merchant should hold enough stock to meet its chosen service promise, cover realistic supplier lead times and support profitable demand. There is no single percentage or stock-turn target that suits every branch or product group. Core, fast-moving lines need different availability from specialist, seasonal or project stock. Set ranges using demand frequency, lead time, margin, criticality and the consequence of a stockout. Then compare the cash invested with the service and gross profit produced. Stock that exists only because it has always been bought is not a policy. The right holding is a deliberate balance between availability, working capital, storage capacity and ageing risk, reviewed when demand or supply conditions change.

How do I know whether we are overstocked?

Overstock exists where the quantity held is greater than realistic demand and service requirements justify. Look for stock days rising faster than sales, duplicated holdings across nearby branches, repeated supplier purchases while older units remain, and lines with no movement beyond their expected cycle. Compare quantity on hand with recent unit demand, committed orders, supplier lead time and minimum order size. Inflation can make stock value and turnover rise together, so use units and age as well as pounds. Separate planned strategic holdings from accidental excess. A business may be overstocked overall while still short of important lines. The useful analysis identifies the product, branch and buying decision that created the imbalance.

How do I reduce stock without damaging customer service?

Reduce the least productive stock first rather than applying one percentage cut across every category. Protect core lines with frequent demand, long lead times or a clear role in the service promise. Focus action on duplicates, excess quantities, completed project stock, superseded products and items with weak or declining demand. Use transfers between branches where genuine demand exists, change replenishment settings and stop automatic reordering before clearing the balance. Track availability, lost sales and urgent buying alongside cash released so that service damage is visible quickly. Sustainable reduction comes from correcting the range and purchasing decisions that created excess. A one-off clearance may release cash, but stock will return if ordering behaviour stays the same.

How do I identify slow-moving and obsolete stock?

Start with age and movement, but interpret both in the context of the product. Flag lines with no sale, low sales frequency or a holding that greatly exceeds expected demand. Review last receipt, last sale, current quantity, open orders, supplier return options and whether the product has been replaced or discontinued. A specialist item may move slowly yet remain commercially important; a common line may be excessive even though it sells every week. Give each flagged line an owner and a reason code so the business can distinguish genuine service stock from project residue, buying error, duplication or obsolescence. The purpose is to create an actionable list, not simply produce an ageing report that nobody owns.

How do I know whether our stock range is too wide?

A range is too wide when additional lines add complexity and cash commitment without enough customer value, margin or strategic purpose. Examine how many products account for most sales and gross profit, then review the long tail by branch. Look for near-duplicates, supplier additions with no removal decision, local ranges copied across all sites and specialist lines held where demand is remote. Range width should reflect the customers served and the branch proposition, not the size of the supplier catalogue. Before removing a line, check substitution, lead time and customer dependency. Good range management makes the reason for holding each category clear and uses access to supplier stock or inter-branch transfer where ownership is more sensible than permanent local holding.

What should I do with dead and ageing stock?

Stop the cause before deciding how to dispose of the balance. Prevent further orders, confirm whether demand exists elsewhere in the branch network and check supplier return or exchange terms. Where appropriate, transfer stock, bundle it with relevant sales, offer a controlled clearance or use it to complete existing commitments. Write down or dispose of stock that has no realistic recovery route rather than preserving an artificial value indefinitely. Record the financial outcome and the original cause, such as project overbuying, inaccurate data or an unmanaged range change. Avoid rewarding sales teams for shifting dead stock at any price if the deal creates more delivery cost or customer expectation. The objective is cash recovery and prevention, not cosmetic movement.

How do I improve stock turn?

Improve stock turn by increasing useful movement and reducing unnecessary holding, not by cutting every line. Correct demand settings, order quantities and review frequencies for the products creating most of the investment. Remove duplicate and obsolete stock, challenge speculative purchases and use branch transfers before new buying where practical. At the same time, protect availability on core lines so lost sales and urgent purchases do not offset the gain. Measure stock turn by meaningful product groups and branches because one headline figure can hide both shortages and excess. Link the measure to gross profit and service: fast movement at poor margin is not automatically better. Lasting improvement comes when buying, range and replenishment decisions respond to evidence rather than habit.

What you may be seeing

Stock value is rising faster than unit sales or gross profit.
Branches hold the same slow lines while still reporting shortages on core products.
Ageing reports are produced, but ownership and action remain unclear.
Project and special-order stock remains after the original customer need has ended.
Clearance activity releases cash temporarily, then the stock balance builds again.

What good looks like

A well-controlled merchant knows which stock supports its service promise and which stock is tying up cash without a clear return. Core availability is protected, while ageing, duplicate and project stock has named ownership and planned action. Branches can see suitable holdings elsewhere before buying again, and replenishment settings reflect current demand and lead times. Range additions include a decision about location, quantity and what they replace. Stock turn, gross profit and availability are reviewed together, preventing one measure from driving poor behaviour. The business releases cash through better decisions and does not depend on repeated clearance campaigns to correct the same problem.

What may be happening underneath

Range decisions: New products and supplier lines are added without deciding what they replace or where they should be held.
Replenishment: Order quantities, minimums and review settings no longer match current unit demand or lead times.
Branch duplication: Sites buy independently even when suitable stock already exists elsewhere in the network.
Ownership: Ageing and project stock has no named person responsible for its next action or prevention.
Buying incentives: Price deals and supplier offers receive more attention than cash, movement and ageing risk.

Questions worth asking

01Which products and branches account for most stock value growth and ageing?
02What service promise or customer demand justifies each major holding?
03Which lines continue to reorder despite excess or weak movement?
04How much stock is duplicated across branches where transfer would be practical?
05What repeated decisions are recreating stock after each clearance exercise?
