Consignment Inventory: When and How to Use It
In a standard purchase arrangement, ownership of inventory transfers to the buyer at the point of purchase — typically upon delivery. The buyer pays for the stock, carries it on their balance sheet, and absorbs any holding costs and obsolescence risk. Consignment inverts this. Under a consignment arrangement, the supplier places inventory at the buyer's location, but ownership remains with the supplier until the buyer consumes or sells the stock. Payment is triggered by use, not by receipt.
This distinction has practical consequences for both parties that go well beyond an accounting technicality.
Benefits for the Buyer
The most immediate benefit is working capital relief. Inventory that is not yet paid for does not tie up cash or credit facilities. For organisations with constrained liquidity, capital-intensive inventory categories, or seasonal demand patterns that create large stock builds, this can be significant. The buyer effectively has access to stock without the carrying cost of ownership.
Risk reduction follows directly. If consigned inventory becomes obsolete, deteriorates, or proves unsuitable, the financial exposure falls primarily on the supplier rather than the buyer — provided the consignment agreement is structured to reflect this. For new product introductions where demand is uncertain, this is particularly valuable: the buyer can stock the item without committing to purchase quantities that may not sell.
Holding cost elimination is the third benefit, though it requires careful interpretation. The buyer still bears the physical costs of storage — space, handling, insurance, environmental controls — regardless of who owns the inventory. What transfers to the supplier is the cost of capital tied up in the stock. The split of physical holding costs versus capital carrying costs matters and should be explicit in the consignment agreement.
Benefits for the Supplier
Consignment is not charity. Suppliers agree to it because it serves their interests in specific circumstances. Placement is the primary motivation: having inventory physically located at a customer's facility creates a strong incumbency advantage. When the customer needs the item, the consigned stock is already there. Competing suppliers face a higher bar to displace an incumbent whose inventory is already on-site.
Reduced returns also feature in supplier calculations. In a standard purchase arrangement, buyers who over-order may return excess stock, sometimes after a significant period. Consignment reduces this pressure by transferring ownership at consumption rather than receipt, which can reduce the return rate and improve the supplier's demand signal.
Risks for the Buyer
Consignment creates a risk of complacency in demand management. When inventory appears to be free until consumed, the incentive to manage stock levels carefully can diminish. Buyers sometimes allow consignment stock to build beyond optimal levels because the carrying cost is not visible in their budgets. This can obscure true demand patterns and create a dependency that complicates supplier transitions.
Reconciliation complexity is the other significant buyer-side risk. Tracking which units have been consumed — and therefore which payments are due — requires robust processes. Discrepancies between the supplier's records and the buyer's consumption data are common and can create disputes. A consignment programme without clean inventory visibility, regular reconciliation cadences, and agreed procedures for discrepancy resolution is a source of ongoing friction.
When to Use Consignment
High-value slow movers — items with significant per-unit cost and relatively infrequent consumption are natural consignment candidates. The working capital benefit is real, and the slow consumption rate makes reconciliation manageable.
New product introductions — where demand is uncertain, consignment allows the buyer to make the item available without committing to purchase quantities. The risk of obsolescence rests with the supplier, which may be appropriate if the supplier is pushing the introduction.
Trial arrangements — organisations considering a new supplier or product category can use consignment as a trial structure, deferring purchase commitment until performance is demonstrated.
Supplier-managed inventory programmes — consignment is frequently combined with vendor-managed inventory (VMI), where the supplier takes responsibility for maintaining stock levels within agreed parameters.
Negotiating a Consignment Agreement
A consignment agreement should address five key areas: the ownership and risk transfer trigger (consumption, use, or sale); physical storage responsibilities and costs; reconciliation frequency and procedure; what happens to excess, obsolete, or damaged consigned stock; and the termination provisions, including the buyer's obligation to return or purchase remaining consigned inventory.
The trigger for risk transfer deserves particular attention. In some agreements, ownership transfers at consumption but risk of loss transfers earlier — for example, at the point the buyer takes physical custody. Getting this language precise is important, particularly for high-value or hazardous items.
Payment terms under consignment are sometimes misunderstood. Payment is triggered by consumption, but the timing of that payment — net 30, net 60 from consumption date — still requires explicit agreement. Suppliers who offer consignment expecting faster net payment once consumption occurs may find that buyers assume standard payment terms still apply to the consumption-triggered invoice.
Structuring supply arrangements that balance working capital, risk, and supplier relationships requires procurement expertise. Our advisory practice supports organisations through these decisions.
