- Online orders can help retailers move inventory out of stores, but only when the routing logic understands local demand. If a store has inventory on hand, it may look like a good fulfillment location but that inventory may already be needed for walk-in customers. Routing an online order from the wrong store can create a stockout, lose an in-store sale, and make the merchandising team rebalance inventory later. HotWax Commerce gives retailers two ways to make smarter store-fulfillment decisions: Sales Velocity and Weeks of Supply. Both help retailers avoid draining the wrong stores, but they are not the same. The difference matters. ## Sales Velocity answers where inventory is moving slowly Sales velocity measures how quickly a product sells at a location. In order routing, it helps retailers prioritize locations where an item is moving more slowly. This is useful when the business goal is simple: route online orders away from high-demand stores and toward stores where the item is not selling as quickly. For example, if a jacket sells nine units a week in a downtown store and one unit a week in an outlet store, Sales Velocity helps the order routing engine prefer the outlet store first. The downtown store keeps inventory available for customers who are already buying the jacket in person. Use Sales Velocity when: - You want to clear inventory from slower-moving stores - You want a simple routing rule based on local demand pace - Available inventory levels are similar across the stores being compared - The main concern is protecting stores where the item is selling quickly Sales Velocity is direct and easy to understand. It tells the routing engine which locations have lower local demand for the item. ## Weeks of Supply answers which location has enough cover Weeks of Supply adds inventory depth to the decision. Instead of only asking how quickly an item sells, Weeks of Supply asks how long the current inventory is expected to last at that location. It compares current inventory with sales velocity, then helps the routing engine prioritize locations with deeper coverage. That difference is important. A store with low sales velocity is not always the best fulfillment location if it only has a few units left. Another store may sell a little faster but have much deeper inventory. Weeks of Supply gives the order routing engine that extra context. Use Weeks of Supply when: - You want to clear overstock without creating store stockouts - Stores have very different inventory positions - You want online orders to help reduce aging inventory - You need to protect high-demand stores and still use store inventory for fulfillment - Merchandising teams care about both sell-through and inventory cover Weeks of Supply is usually the stronger choice when the business decision is about balance. It helps retailers use online demand to reduce excess inventory while keeping enough stock in stores where local customers are still buying. ## The difference in practice Imagine three stores can fulfill the same online order. ![Table comparing inventory and sales velocity at downtown, suburban, and outlet stores to route orders](https://www.hotwax.co/hs-fs/hubfs/blogs/when-to-route-orders-by-sales-velocity-vs-weeks-of-supply/store-inventory-vs-sales-velocity.png?width=742&height=244&name=store-inventory-vs-sales-velocity.png) If the retailer sorts by Sales Velocity, the outlet store is preferred because the item sells slowest there. If the retailer sorts by Weeks of Supply, the outlet store is still likely the best location, but for a better reason: it has the deepest inventory cover. The routing decision is not just based on slow movement. It is based on the store’s ability to spare inventory without hurting local demand. Now change the example slightly. The outlet store has only 2 units left, while the suburban store has 14 units. Sales Velocity may still identify the outlet as the slowest-moving location. Weeks of Supply can identify that the suburban store has healthier coverage and is the better fulfillment source. That is the practical difference: Sales Velocity looks at demand pace. Weeks of Supply looks at demand pace plus inventory depth. ## When to prioritize Sales Velocity Prioritize Sales Velocity when the routing goal is to move orders away from stores where the item sells quickly. ![Inventory sort settings with sales velocity selected to route orders to faster selling stores](https://www.hotwax.co/hs-fs/hubfs/blogs/when-to-route-orders-by-sales-velocity-vs-weeks-of-supply/inventory-sort-sales-velocity.png?width=521&height=337&name=inventory-sort-sales-velocity.png) This works well for broad clearance strategies where stores have similar inventory levels and the retailer wants to favor slower-moving locations. It is also useful when merchandisers want a straightforward rule that reflects local demand. Sales Velocity is a good fit for: - End-of-season items that need more sell-through across the store network - Products with similar inventory depth across eligible stores - Store groups where the main difference is demand, not stock availability - Routing strategies that need a simple slow-mover preference The limitation is that Sales Velocity does not explain whether a slow-moving store has enough inventory to spare. It should usually be paired with Facility Group, Brokering Safety Stock, or another inventory filter that protects minimum inventory. ## When to prioritize Weeks of Supply Prioritize Weeks of Supply when the routing goal is to make a more complete inventory decision. ![Inventory filter settings with weeks of supply selected to route orders by weeks of supply](https://www.hotwax.co/hs-fs/hubfs/blogs/when-to-route-orders-by-sales-velocity-vs-weeks-of-supply/inventory-filter-weeks-of-supply.png?width=478&height=405&name=inventory-filter-weeks-of-supply.png) This is the better option when stores have uneven inventory positions. It helps retailers avoid the common mistake of clearing inventory from a slow-moving store that is already low on units, while ignoring another location that has more cover. Weeks of Supply is a good fit for: - Clearing dead stock from stores with excess cover - Protecting stores with strong walk-in demand - Reducing future store-to-store transfer work - Using ship-from-store fulfillment without weakening store presentation - Balancing warehouse-first and store-fallback routing strategies Weeks of Supply is especially useful for merchandisers because it reflects how inventory feels in the store. A product with 10 units may be healthy in one location and risky in another. The difference depends on demand. ## How HotWax Commerce lets retailers use both [HotWax Commerce](https://www.hotwax.co/order-management-system) order routing is built around layered rules. Retailers do not have to choose one signal for every order. A common strategy is: 1. Use Facility Group to define which locations are eligible for shipping 2. Use Proximity when delivery speed or shipping cost matters 3. Use Brokering Safety Stock to protect minimum inventory 4. Use Sales Velocity when the goal is to favor slower-moving locations 5. Use Weeks of Supply when the goal is to favor locations with deeper inventory cover For example, a retailer may route standard eCommerce orders through warehouses first. If the warehouse cannot fulfill the order, the next rule can evaluate stores within a specific region. Within that store group, Weeks of Supply can prioritize the location with the healthiest inventory cover. During a clearance period, the retailer may create a separate routing strategy for outlet stores or low-demand locations. Sales Velocity can help prioritize slower-moving stores, while Weeks of Supply can refine the final decision when inventory depth varies. ## The business outcome The best fulfillment location is not always the closest store or the store with the most units. It is the location that can fulfill the order while supporting the retailer’s broader inventory goals. Sales Velocity helps retailers protect demand. Weeks of Supply helps retailers protect demand and manage inventory cover. HotWax Commerce gives retailers both options because order routing is not just an operations decision. It is a merchandising decision, an inventory decision, and a customer promise decision at the same time. \*     \*     \*  See how HotWax Commerce [Order Routing Solution](https://www.hotwax.co/order-routing) helps retailers protect store inventory while scaling omnichannel sales.
