Visibility by variant
Every style is slotted by size and color, so a picker reaching for a medium in black is not digging through a bin of mixed sizes. A new collection is slotted and ready to ship within one business day of receipt.

The styles nobody is buying still cost you every day. Find them early and decide what to do with them on purpose.
Every apparel brand ends up with some stock that stops moving. At a thousand orders a month and up, it builds quietly in the corners of the catalog: one size here, one color there, a whole style that missed. The problem is not that it exists. The problem is finding it late.
Dead stock is easy to see once it is a year old. The goal is to see it in week six.
Look at inventory by variant, not by style. A hoodie that is selling fine as a style can still hide two sizes and one color that have not moved since they arrived. At OC3PL every size and color is its own SKU with its own location and count, so the report shows you the variant that is stuck, not an average that looks healthy.
Two simple measures do most of the work. Sell-through compares what you sold with what you received over a period. Weeks of supply divides what is on hand by what you sell in an average week. A variant with a low sell-through and a long weeks-of-supply number is your early warning.
| Signal | What it looks like | What to check |
|---|---|---|
| Weeks of supply keeps climbing | Sales slowed but stock did not | Was the style promoted? Is it still on the site’s main collection pages? |
| One size never moves | The core sizes reorder, the edges sit | Your size curve, and your return reasons for that size |
| A color stalls after launch | Strong first week, flat after | Product photos and how the color reads on screen |
| Returns pile up on one style | Units come back and do not resell | Fit notes, the size chart, and the condition rules you set |
| Stock with no channel | Units held for wholesale that never shipped | Whether the purchase order is still open |
Your weekly reporting from OC3PL covers service levels, shipping costs and inventory status. Use it as the moment to scan for these signals every week, rather than waiting for a quarterly count to surprise you.
Storage is the cost everyone sees. At OC3PL storage is based on the space your inventory actually uses and is pro-rated daily, so a slow style keeps costing a little every single day it sits. Slow-moving SKUs still carry a monthly cost, which is why storage should be reviewed against sell-through regularly instead of treating the warehouse as free space between drops.
The costs nobody invoices are bigger:
Pick the route on purpose. Each one is something the warehouse can execute once you decide.
Pair a slow color with a best seller, or build a two-pack. OC3PL supports kitting to stock and kitting to order, and most builds are completed within 24 to 48 hours. See apparel kitting and bundles.
A slow tee, hat or accessory can become the free gift on orders over a set value. A flexible integration can add a gift SKU automatically when an order crosses a threshold, so nobody has to remember it at the packing station.
An archive or sample sale is a drop in reverse: lots of orders in a short window. Plan it the same way, with a forecast sent ahead so labor is scheduled. The apparel drop fulfillment page covers the timeline.
An off-price buyer or a store partner may take a whole run. Cartons can be packed, labeled and palletized for freight from the same inventory. See apparel wholesale and retail.
Seeding, staff uniforms, donation or a return to your own storage: tell your account manager where the units should go and they are pulled and shipped out, so they stop counting against your active catalog.
Most dead stock is decided at the buying stage. Three habits help:
Your account manager is on site, in the building where the stock sits. If you want to walk the slow styles together, physically or on a call, that is a normal request. We’re here, we got you.
The warehouse side of a decision you make.
Every style is slotted by size and color, so a picker reaching for a medium in black is not digging through a bin of mixed sizes. A new collection is slotted and ready to ship within one business day of receipt.
Kitting to stock or to order. Most builds are completed within 24 to 48 hours.
Returns are processed and logged within 48 hours of receipt, and many are handled the same day. Each item is inspected and restocked, discarded or donated by the rules you set.
Units you retire from sale are pulled and sent where you decide, so they stop cluttering the active catalog.
Any variant that has stopped selling at a pace that justifies holding it. In apparel it is usually one size, one color or one style rather than a whole product line, which is why it is easy to miss in style-level reports.
Look at inventory by size and color every week. Watch weeks of supply and sell-through per variant, and check return reasons for the styles that look slow.
It costs the same per unit of space, every day it sits. At OC3PL storage is based on the space you use and pro-rated daily, so clearing slow stock lowers the bill right away.
Yes. Kitting can be done to stock ahead of time or to order as orders arrive. Most builds are completed within 24 to 48 hours, and kitting is quoted per kit or hourly depending on complexity.
Yes. Wholesale orders ship from the same inventory, packed, labeled and palletized for freight, or as parcels for smaller orders.
Buy sizes in the proportion they actually sell, start with smaller runs and restock winners, and read return reasons monthly before you reorder.
