You still share the ground rules, things like minimum and maximum quantities, how much shelf space the line gets, and what service looks like, but the week-to-week decision of when to reorder and how much to send belongs to the vendor, not to your buyer. The detail that surprises people the first time: in standard VMI, you still buy and own the inventory the moment it lands on your dock, and you pay for it on your normal terms. VMI changes who decides the order, not who owns the goods. Ownership is a separate question, and it is where consignment enters the picture, which we will get to shortly. Vendors offer it for plain reasons. They know their line better than anyone, they would rather manage the shelf than lose it to a competitor, and a well-stocked display sells more of their product. Your side of the bargain is equally clear: you hand over some control in exchange for getting buyer hours back. ## How VMI works in a supply store In practice, VMI in an independent supply store runs on one of two fuels: data or shoe leather. The data version looks like this. You share sales and on-hand figures for the vendor's line, often through an EDI feed or a portal login, and the vendor's system generates replenishment orders against the min and max levels you agreed on. The order arrives on the weekly truck, your crew receives it against the packing slip, and the shelf stays full without anyone on your payroll touching it. The shoe-leather version is older and still common. A territory rep pulls into your lot on a Tuesday, walks the display with a scanner or a clipboard, counts what is missing, and writes the order on the spot. That is the same shoot-the-outs walk your own buyer would do, except the person doing it works for the mill, the distributor, or the fastener company. Either way, VMI tends to show up in the same corners of a supply store: fastener drawers and bin displays, seed packet racks in the garden center, small hardware displays like key blanks and batteries, bagged feed or minerals that a mill rep services, propane cylinder exchanges, and seasonal endcaps that need constant attention from March through June. These are lines with lots of small SKUs, steady turns, and real upkeep, which is exactly the kind of work a busy buyer is happy to hand off. ## VMI vs consignment vs rack jobbing These three terms get tangled together at buying group meetings, so it is worth keeping them straight, because the difference is who owns the goods and who does the work. | Arrangement | Who decides the order | Who owns the stock on your shelf | When you pay | | --- | --- | --- | --- | | Vendor managed inventory | The vendor, within agreed limits | You, once delivered | On your normal terms | | Consignment | Usually the vendor | The vendor, until the item sells | Only for what sold | | Scan-based trading | Usually the vendor | The vendor, until checkout | At the moment of scan | | Rack jobbing / service merchandising | The vendor's rep, shelf by shelf | Typically you, sometimes the jobber | Depends on the deal | Consignment is the ownership twist: the goods on your shelf belong to the vendor until they sell, and you pay only for what moved. Scan-based trading is a consignment variant where ownership transfers the instant the item scans at your register. Consignment often rides along with VMI, but they answer different questions, and you can have either one without the other. Rack jobbing, sometimes called service merchandising, is the grandfather of the whole idea. A jobber's rep services a specific display, such as fastener drawers, key blanks, seed racks, gloves, or batteries, merchandises it, pulls the stale stock, and writes the reorder. If your grandfather's hardware store had a seed rack that magically refilled itself every spring, that was a rack jobber doing vendor managed inventory before anyone thought to give it an acronym. ## The upside for your store The clearest win is time. A fastener line with 400 SKUs or a seed rack with 200 packets can absorb a buyer's whole morning every week, and handing that line to a vendor frees those hours for the categories where your judgment earns its keep, like lumber quotes, contractor pricing, and the seasonal buys where a wrong call is expensive. The second win is expertise. The vendor's rep sees its line across dozens of stores, so it knows which hinge size is quietly taking off two counties over and which one is a dog everywhere it goes. A good rep catches stockouts you would miss, keeps the planogram tidy, replaces faded packaging, and rotates stock so the oldest feed bags sell first. On lines the vendor watches closely, fill rate can improve, because nobody at your store has time to watch those SKUs that closely. ## The risks to watch The tension at the heart of every VMI deal is that the vendor's incentive is to sell you more, and your incentive is to turn what you have. Those overlap most of the time and diverge exactly when it matters, which is how stores end up with a fourth row of slow-moving socket sets nobody asked for. Beyond overstock, keep an eye on a few quieter risks. When the vendor manages the line, it is easy to stop looking at margin and inventory turns on those SKUs, and a line can drift from a solid performer to a shelf-warmer while nobody is watching. Data sharing cuts both ways too: the sales feed your vendor needs to replenish is also a window into your store, so be deliberate about what they see. Ask who sets retail pricing on the line, how returns of slow movers and seasonal leftovers work, and what happens when your rep leaves or the route changes, because a VMI line that depends on one good rep can go sideways fast when that rep's territory gets redrawn. ## Terms to nail down in a VMI agreement Most VMI grief traces back to terms that were discussed in the parking lot and never written down. Before you sign anything, get these points on paper: * **Ownership and payment terms.** Who owns the stock and exactly when title transfers, and whether you pay on normal terms, on consignment, or at scan. * **Min/max levels and shelf allocation.** The agreed limits, and who is allowed to change them. If the vendor can raise the max on its own, your open-to-buy is no longer yours. * **Data access.** What sales and inventory data the vendor receives, how often, and whether the feed covers the whole store or only the vendor's line. * **Returns and rotation.** How slow movers, damaged goods, and end-of-season leftovers come back out, and who pays the freight on the way. * **Retail pricing.** Who sets the shelf price, and how cost increases flow through to your margin. * **Service frequency.** How often the rep or the data feed drives an order, and what happens between visits when a hot SKU runs out. * **Shrink and damage.** Who absorbs count discrepancies and damaged product on a vendor-managed display. * **The exit.** How either side ends the arrangement, how much notice is required, and who buys back the remaining stock. The best time to negotiate a graceful goodbye is while everyone is still friends. ## How to tell whether VMI is working A VMI line earns its shelf space the same way every other line does: inventory turns, GMROI, and fill rate. The trap is assuming the vendor is watching these numbers for you. The vendor is watching its own numbers. Take an illustrative fastener display. Say you carry $3,000 of inventory at cost and the line produces $9,000 in annual sales at cost. That is 3 inventory turns a year. If your gross margin on the line is 45% of retail, annual retail sales come to roughly $16,364 and gross margin dollars to roughly $7,364, which puts GMROI at about 2.45. In plain terms, each dollar sitting in those drawers returns about $2.45 of gross margin per year. Now compare that against the lines your own buyer manages. If the VMI line turns slower and earns less per dollar than your in-house lines of similar size, the arrangement is costing you money no matter how tidy the display looks. (The math behind both metrics is laid out in our guide to [inventory turnover ratio and GMROI for hardware stores](/resources/guides/inventory-turnover-ratio-and-gmroi-for-hardware-stores/index.md).) A few more checks worth putting on the calendar. Track the dollars of VMI stock older than 180 days, because slow movers are where the vendor's optimism shows up on your balance sheet, and our guide to [finding and clearing dead stock](/resources/guides/dead-stock-how-to-find-and-clear-it/index.md) covers what to do with what you find. Watch fill rate in the practical sense: are the fastener bins full when a contractor reaches into one on a Saturday morning. And every so often, reconcile the rep's count against your point of sale. If the rep's scanner says 40 boxes of deck screws and your system says 28, run a quick [cycle count](/resources/guides/cycle-counting-for-retail-stores/index.md) of that display before the discrepancy becomes a shrink argument at year end. ## When to keep ordering in-house VMI is a tool, not a default, and some lines deserve to stay in your buyer's hands. Keep ordering in-house when the line is a big share of your margin, because nobody at the vendor's office will defend your gross margin dollars the way you will. Keep it in-house when your judgment is the advantage, as with lumber, seasonal garden buys, and the contractor-driven categories where knowing your customers' jobs beats any algorithm or route schedule. Keep it in-house when the vendor's data ask makes you uneasy, when the line turns too slowly to justify a service visit, or when the previous rep's route changed twice in a year and the coverage has been patchy ever since. A healthy middle ground works for many stores: run your own min and max replenishment on most lines, reserve VMI for the fussy, high-SKU displays where the vendor's attention beats yours, and review every VMI line once a quarter with the same rigor you would give a line you manage yourself. The stores that get burned are rarely the ones that said no to VMI. They are the ones that said yes and stopped looking. ## How Rundoo handles it Rundoo is the store's system rather than a vendor VMI platform, so its role is twofold: giving you the tools to keep replenishment in-house when you want to, and giving you the numbers to check a vendor-managed line when you do not. For in-house ordering, Min and Max are set per product, per location, and when on hand plus on order drops to or below the Min, Rundoo suggests enough to bring stock up to the Max, rounded up to case quantity. Generate order fills a proposed purchase order using Replenishment, Min & Max, or Predictive logic, and a product can carry more than one vendor, so a backup source is already on file. Dooey can draft a reorder list into a draft purchase order, and scheduled AI agents can draft a weekly reorder for your review and approval, which gets you much of the time savings VMI promises without handing anyone the pen. Our guide to the [reorder point and safety stock formula](/resources/guides/reorder-point-and-safety-stock-formula/index.md) walks through the math behind setting those mins and maxes, and the [purchase order process guide](/resources/guides/purchase-order-process-for-retail/index.md) covers the document flow from there. For checking a VMI line, the Inventory view shows on hand, committed, available, and on order per location, so you can check a rep's count against your own numbers. Custom reports include an Inventory dataset with fields like last sale date, annual units sold, annual turns, and on-hand value, which you can group by vendor to see exactly how the fastener company's line performs next to the lines you manage yourself. Pricing and purchasing controls live in [Rundoo's purchasing tools](/product/manage-pricing-purchasing/index.md).

Vendor managed inventory (VMI) is an arrangement where the vendor, rather than the store's buyer, decides when and how much to replenish a line, using the store's sales and on-hand data or a rep's shelf walk, within agreed limits such as min and max levels or shelf space. In standard VMI the store still buys and owns the stock once it is delivered and pays on normal terms. What is the difference between VMI and consignment? VMI changes who decides the order, while consignment changes who owns the goods. Under consignment the vendor owns the stock on your shelf until it sells and you pay only for what sold, and the two are often combined but can each exist without the other. What are the disadvantages of vendor managed inventory? The vendor's incentive is to sell you more, so VMI lines can drift into overstock and slow movers while nobody at the store watches their turns and margin. Other risks are sharing sales data, losing control of retail pricing, unclear returns of seasonal leftovers, and patchy service when a rep leaves or a route changes. How do I know if a VMI program is working? Measure the line the way you measure your own: inventory turns, GMROI, fill rate when customers reach for an item, and dollars of stock older than 180 days. If the VMI line turns slower and earns less gross margin per dollar of inventory than comparable lines your buyer manages, it is costing you money. ## Find out what Rundoo can do for your business Learn how Rundoo can help you save time, money and hassle running your business.
