Consignment Inventory vs Vendor-Managed Inventory (VMI)

SECTION 01What is consignment inventory?

In brief: Consignment inventory is stock placed at the buyer's location (the consignee) while the supplier (the consignor) retains ownership. The buyer pays only when each unit sells, and unsold stock can typically be returned. The seller carries the inventory risk and the capital cost; the buyer provides shelf space and the sales channel.

Consignment answers a cash question: who should have money tied up in stock that has not sold yet? Under consignment, the answer is the supplier. The goods physically sit in your warehouse or store, you sell them through your channels, and only at the moment of sale does ownership flash from supplier to you to customer, with payment following on the agreed cycle. Unsold units go back under the terms of the agreement rather than becoming your write-off.

A concrete example. A skincare brand places 2,000 units with a boutique retail chain on consignment. The chain stocks them across ten stores, pays nothing upfront, and reports sales weekly. In month one, 600 units sell: the chain remits the agreed price on 600 and continues selling. At season end, 150 slow movers return to the brand. The chain risked shelf space, not capital; the brand bought distribution it could not have negotiated on standard wholesale terms, because the retailer's risk was near zero. That trade, supplier carries the risk to buy the placement, is the essence of every consignment deal, and it is why new brands, unproven SKUs, and expensive slow-turning goods are consignment's natural territory.

SECTION 02What is vendor-managed inventory (VMI)?

In brief: VMI is an arrangement where the supplier takes over replenishment decisions for their products at the buyer's location: monitoring the buyer's live stock and sales data and shipping against agreed minimum and maximum levels. Ownership usually transfers on delivery as in normal purchasing; what moves to the supplier is the forecasting and ordering work.

VMI answers a different question: who is better placed to decide when to reorder? For a supplier's own product line, the supplier often is, since they see demand across every customer they serve, know their own production and lead times precisely, and care deeply about not being the cause of an empty shelf. Under VMI, the buyer stops raising purchase orders for those SKUs. Instead, the supplier watches the buyer's stock and sell-through data, and ships replenishment automatically whenever levels approach the agreed minimum, never exceeding the agreed maximum.

The canonical example. The Walmart and Procter & Gamble partnership of the late 1980s is the textbook case: P&G took over replenishment of its own products in Walmart's distribution centers, working from Walmart's sales data. Stockouts fell, inventory levels fell, and both sides shed forecasting duplication, which is why the model spread across retail and manufacturing. The buyer's win is fewer stockouts with less planning workload; the supplier's win is smoothed demand visibility instead of lumpy surprise POs, which stabilises their own production. Note what did not change: Walmart still owned the stock it received, paid on normal terms, and carried the inventory on its books. Only the decision moved.

SECTION 03What is the actual difference between consignment and VMI?

In brief: Consignment moves ownership: the supplier's stock sits at the buyer's site, paid for only when sold. VMI moves the replenishment decision: the supplier decides when and how much to ship, but the buyer typically owns stock on delivery as normal. Consignment solves a cash and risk problem; VMI solves a forecasting and workload problem. The two can be combined.

Nearly all the confusion between these models dissolves against the two-question test from the top of this guide.

Keep the one-liner: consignment moves ownership; VMI moves the replenishment decision. Everything else in the table is a consequence of those two moves, including the payment timing, the risk allocation, and what data each partner must be able to see.

SECTION 04What are the pros and cons of each model?

In brief: Consignment gives buyers stock without capital and gives suppliers distribution, at the cost of the supplier's cash being tied up and heavier tracking demands. VMI cuts stockouts and planning workload for buyers and smooths demand for suppliers, at the cost of buyer dependence on the supplier and the data-sharing infrastructure both need.

SECTION 05How does consignment inventory accounting work?

In brief: Consigned stock stays on the supplier's (consignor's) balance sheet until sold; the buyer (consignee) holds it physically but never records it as inventory. On sale, the consignor recognizes revenue and cost of goods sold, and the consignee records its commission or margin. Both parties must track the same units separately, which makes reconciliation discipline essential.

The accounting is where consignment discipline gets tested, because the physical location and the balance sheet disagree on purpose. For the consignor (supplier): goods shipped on consignment are not sales, they move to a "consignment inventory" account and stay on your books, at cost, until the consignee reports a sale, at which point revenue and COGS are recognized. For the consignee (buyer): consigned goods never enter your inventory asset, no matter that they fill your shelves; your books see only the commission or margin earned on each reported sale.

Three practical consequences follow. First, segregation: consigned stock must be identifiable and countable separately from owned stock, physically or systemically, or your balance sheet and your warehouse start lying to each other. Second, reporting cadence: the consignor recognizes nothing until sales are reported, so weekly or real-time sales visibility is a financial control, not a courtesy. Third, reconciliation: periodic counts of consigned stock against both parties' records are what keep the relationship honest, and unsold-stock returns flow through the same disciplined process as any B2B return, which our returns management playbook covers.

SECTION 06Can you combine consignment and VMI?

In brief: Yes, and it is common: the supplier both owns the stock at the buyer's site and manages its replenishment. The buyer provides space and sales channels with near-zero risk or workload; the supplier controls availability and pays for the privilege with capital. Scan-based retail and spare-parts programs frequently run exactly this way.

Since the two models move different levers, nothing stops a relationship from moving both. In the hybrid, sometimes called supplier-owned VMI or scan-based trading in retail, the supplier owns the consigned stock and decides its replenishment, monitoring sell-through and topping up automatically, invoicing only as units scan through the till. The buyer's involvement approaches zero: provide the space, sell the goods, share the data. The supplier accepts maximum exposure, capital plus workload, in exchange for maximum control of their product's availability, which for a brand fighting for retail presence is often exactly the trade worth making. The hybrid is also the most demanding configuration on data: real-time sales, real-time stock, and airtight reconciliation, for stock the host never owns.

SECTION 07When should you choose which model?

In brief: Choose consignment when the blocker is risk or cash: unproven products, new retail relationships, expensive slow movers. Choose VMI when the blocker is forecasting and workload: steady-volume SKUs from a capable, trusted supplier. Combine them when a supplier wants control of availability and is willing to fund it. Skip both when partner data or trust is weak.

The decision usually makes itself once you name the actual blocker:

• The retailer will not take the risk on our brand → offer consignment. You are buying distribution with your balance sheet.
• We keep stocking out of a reliable supplier's SKUs → propose VMI. Their visibility beats your forecast for their own products, and the replenishment math (the same safety-stock-and-reorder-point machinery in our safety stock guide) moves to the party with better data.
• We are the brand, and shelf availability at our retail partners is the growth constraint → propose the hybrid, and treat the carrying cost as a distribution investment.
• The partner cannot share reliable stock and sales data → fix that first, or choose neither. Both models fail identically on bad data: the consignor cannot invoice what is not reported, and the VMI supplier cannot replenish against numbers that are wrong.

SECTION 08What systems do consignment and VMI actually require?

In brief: Both models run on shared, accurate, real-time inventory data: consignment needs stock you hold but do not own (or own but do not hold) tracked separately and reconciled continuously, while VMI needs the supplier to see live stock and sell-through. That means multi-location, multi-ownership inventory visibility with partner access, not spreadsheets emailed weekly.

Strip either model to its failure modes and every one is a data failure: unreported consignment sales, phantom stock the VMI supplier replenishes against, owned and consigned units mingled beyond audit. The infrastructure requirement is the same in both directions. You need every unit tracked by location and by ownership, sales flowing through in real time, and the partner seeing exactly the slice of your data the agreement grants, no more, no less.

This is precisely the operating problem EasyEcom's retail and wholesale distribution solution exists for: brands running D2C, marketplace, and retail-wholesale channels from one stock pool, with partner-level visibility, B2B order flows, and ERP-synced records. Borosil runs its retail-wholesale glassware operation this way on EasyEcom, with inventory centralized across channels and regions, SAP kept in auto-sync, and manual data entry eliminated, which is exactly the record-keeping backbone a consignment or VMI program stands on.
