Switching apparel 3PLs
Moving thousands of variants without a stockout or a missed drop.

The warehouse that worked at 200 orders a month is not always the one that works at 2,000. Here is how to tell, and what to do about it.
Each of these is a symptom of a warehouse that is not set up for apparel at your volume. One bad week is a bad week. The same problem every month is a pattern.
A symptom points to a cause. Find the cause before you decide to move.
When the wrong size goes out, the cause is almost always in slotting or scanning. If several sizes of one style share a bin, a picker in a hurry grabs the wrong one. If the pick is not scanned, nothing catches the mistake before the box is sealed. Ask your current warehouse two questions: are sizes slotted separately, and is every unit scanned at the pick? If the answer to either is no, the error rate will rise with your volume.
A drop that ships days late usually means the warehouse did not plan labor for it, or did not have stock received and slotted before the link went live. Both are planning failures. A partner set up for apparel asks for your drop date and forecast ahead of time and schedules the floor for it.
Returns that sit for weeks mean returns are treated as a side job. For apparel, that is expensive: a returned medium that is not back on the shelf cannot be sold, and a customer waiting on an exchange is a customer you may lose.
Counts that drift come from receiving that is not checked against the advance shipping notice, unscanned picks, or returns that are not processed. See apparel inventory accuracy for the checks that keep counts right.
If you cannot reach a person who can see the problem, every other problem lasts longer. This is the one sign that no process document fixes. It depends on where your account manager works and how quickly they answer.
Be honest about which problems start on your side.
Some problems that show up at the warehouse start upstream. Before you move, check your side of the handoff. A good partner will tell you plainly which is which.
| Problem | Often the warehouse | Often the brand |
|---|---|---|
| Wrong size shipped | Mixed bins, no scan at the pick | Two sizes sharing one barcode |
| Inventory does not match | Receiving not checked against the ASN | No ASN sent, or cartons not labeled |
| Drop shipped late | No labor plan for launch day | No forecast sent, stock arrived the day before |
| Returns slow | Returns handled when someone has time | No written rules for restock, discard or donate |
| Bundles wrong | Kits not verified by scan | Bundle rules changed without notice |
If most of your problems sit in the left column, the warehouse is the issue. If they sit in the right column, fix those first. Moving to a new 3PL with the same inputs gives you the same outputs.
Hold any warehouse, including us, to a clear standard. At OC3PL:
Scale is part of the standard too. One apparel brand on our results page grew from 500 to 5,000 orders a day over two years and moved into big-box retail without changing warehouses. The question is not only whether a warehouse handles you today, but whether it handles you at three times the volume.
If you want to talk it through with someone who runs an apparel floor every day, call us. We are here. We got you.

Why it matters where your account manager works.
Twenty questions to ask any warehouse, with our answers.
Your account manager works on site at our Anaheim fulfillment center, in the same building as your inventory. When something is urgent you call and talk to a person who can walk to the shelf and fix it. Call anytime. We are here. We got you.
Look at where each error starts. Wrong sizes from mixed bins and late shipments from unplanned labor are warehouse problems. Missing barcodes, unlabeled cartons and late forecasts are yours. A good partner will tell you which is which.
After, or well before. Never in the weeks just before a drop or Black Friday. Moving in a quiet stretch lets daily orders run cleanly before the first big event.
Any repeated mistake with the same cause is too many, because it shows nothing has been fixed. Track errors by type and by month, and ask your warehouse what changed after each one.
Yes, and you should. Put the problems in writing with dates and order numbers, ask for a plan, and set a date to review it. If nothing changes, you have your answer.
