Consignment and VMI Stock for Garment Trims: Levels, Billing and Contract Terms

A few garment trims are small in volume yet unforgiving when they run out: care labels, neck labels, hang tags, tag fasteners and packaging bags. Their unit price is low, but a single missing piece can hold back a whole garment shipment, so holding a slice of stock close to the customer has become common practice. That is what consignment and vendor managed inventory (VMI) mean: goods sit in the customer's or a third party's warehouse, ownership stays with the supplier, and only what is consumed gets invoiced. Simple in outline; what makes it hard in practice is the stock level, the reconciliation and the exit clause.

This guide moves from whether to do consignment to how to write it into a contract: the difference between three stocking models, the conditions under which consignment pays, how to set stock levels, how consumption-based invoicing and monthly reconciliation work, whether to hold the goods at the supplier's warehouse, inside the customer's factory, in a bonded warehouse or in an overseas warehouse, and the clauses that have to be explicit. The final section lists the six items worth stating in the conversation.

1. Three Stocking Models: Separate Them First

All three are called stocking, yet the money and the risk sit in different places. Lining them up side by side shows whether consignment is really the model you need.

2. When Consignment Actually Pays

• Predictable usage: the same style reorders continuously and monthly volume stays within roughly plus or minus thirty per cent, which is what makes a stock level calculable.
• Few, well-chosen SKUs: consignment suits five to twenty standing items; putting dozens or hundreds of SKUs on consignment lets the administrative cost eat the capital it saves.
• Low unit value, high cost of a stockout: a carton of care labels or fasteners ties up little money, but one missing item stopping a line costs far more than the capital held.
• Replenishment longer than the customer can tolerate: on a lane where sea freight takes 25 to 35 days, consignment shows its value most clearly.
• A customer willing to share data: at least weekly stock and consumption figures, otherwise VMI is just stock parked at the customer's site, not management.

3. Setting the Stock Level

A stock level is not a guess. Three numbers build the frame: average daily consumption (D), replenishment lead time (L) and safety stock (S). Everything else is adjusting the coefficients between them.

• Reorder point = D × L + S. Safety stock is commonly thirty to fifty per cent of D × L; for volatile items use one to 1.65 standard deviations instead.
• Maximum level = reorder point + replenishment lot. Keep the lot above the supplier's minimum: trial orders for hang tags commonly start at 2,000 to 3,000 pieces, woven and care labels often at 1,000 metres or 300 to 500 pieces.
• Review actual against forecast monthly. If the deviation exceeds thirty per cent two months running, the level or the forecast needs adjusting, not more stock.
• Two-bin or min/max boards cut down on human judgement: when the first bin empties, replenishment triggers, and the second bin is only buffer. The simpler the rule, the more likely it is followed.

4. Billing and Reconciliation: Where Consignment Argues Most

• The point at which ownership and risk pass must be explicit. Most arrangements transfer on draw, leaving transit and storage losses with the supplier; others transfer on arrival, with the price adjusted accordingly. Either works, ambiguity does not.
• Consumption-based invoicing: invoice monthly against the customer's actual draw records, whether issue notes or system data, with a fixed reconciliation date such as the fifth of each month for the previous month.
• Count variances: agree a tolerance, commonly plus or minus one per cent, with anything beyond it borne by the responsible party. Count quarterly, or once before and after each season change.
• Price adjustment windows: paper, yarn and exchange rates all move, so agree a quarterly adjustment with thirty days' written notice; that holds a long relationship far better than ad hoc increases.
• Currency and rate basis: in foreign currency, state which rate applies, for example the mid-rate on the invoice date or last month's average. Leaving it open is the classic quarter-end dispute.

5. Where to Hold the Goods: Four Locations Compared

6. Clauses That Have to Be Explicit

• Minimum purchase commitment: consignment does not mean the customer has no obligation. Agree an annual minimum draw or minimum purchase value, or the stock risk sits entirely on one side.
• Stock ceiling and slow-moving stock: set a maximum level and agree that items untouched beyond a period, twelve months for example, are either bought out at a discount or returned, with freight responsibility stated.
• Versions and revisions: once a trim changes material or colour reference, the fate of old stock must be written in advance. The usual answer is a transition window during which both versions ship.
• Quality liability and claim windows: when defects surface at the customer's warehouse, the traceability route and the replenishment deadline must be clear, three working days after written notice for instance.
• Data visibility: the customer provides real-time or at least weekly stock and consumption data. This is the premise that makes VMI work and the only basis for lowering the level.
• Termination and buy-back: the buy-back ratio for remaining stock, the deadline and who pays freight should be written at the start, not negotiated on the day the partnership ends.
• Exclusivity: whether the supplier is exclusive for the category affects future negotiating room, so bound it by time rather than leaving it open-ended.

7. Six Items to Bring to a Consignment Discussion

• The list of standing SKUs with per-item specifications: material, size, process and packing.
• Monthly consumption per item and the seasonal swing: how many times busier the peak is.
• Your current replenishment lead time and the longest stockout you can accept.
• The preferred location and its city: supplier warehouse, your plant, bonded or overseas.
• Billing cycle, currency and payment terms: monthly or bimonthly, and how many days.
• Annual volume forecast and the minimum commitment you can offer: with a committed volume the supplier has room to optimise both price and level.
