Slotting
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.

A third-party logistics partner that stores, packs and ships your clothing, and handles what comes back.
A 3PL, or third-party logistics provider, runs the physical side of ecommerce for you. An apparel 3PL is one set up for the way clothing works: many sizes and colors, folding and bagging, drops, and a lot of returns.
You keep the brand. The 3PL runs the warehouse.
When a brand works with a 3PL, it sends its inventory to the 3PL’s warehouse. The 3PL connects to the brand’s online store, so every new order arrives in the warehouse system automatically. Staff pick the items, pack them to the brand’s instructions, and hand the package to a carrier. Tracking flows back to the store and the customer.
The brand still owns the product, the website, the customers and the decisions. It sets the packing rules, the return policy and the launch dates. The 3PL is responsible for doing the physical work accurately and on time, and for reporting what happened. For a fuller general explanation, see what a 3PL is.
Any warehouse can store boxes. Clothing asks for more. A general warehouse that treats a hoodie the same as a phone case will struggle with apparel in a few predictable places.
| Apparel need | What a general warehouse may do | What an apparel 3PL should do |
|---|---|---|
| Many sizes and colors | One bin per style, sizes mixed | One location per size and color |
| Similar-looking variants | Pick by eye | Scan every unit at the pick |
| Brand presentation | Stuff and ship | Fold, bag and pack to your instructions |
| Frequent returns | Process when there is time | Inspect and restock within days |
| Drops and launches | Same staffing every day | Plan labor from your forecast |
| Wholesale accounts | Parcel only | Retail labels, routing guides and freight |
You can read more about each of these in how apparel fulfillment works and size and color variants explained.
Most 3PLs bill for the work they do, one line at a time. The common lines are receiving, storage, pick and pack, packaging materials, returns and shipping. Pick and pack is often a per-order fee plus a per-item fee. Storage is usually based on the space your inventory takes up. Shipping is billed at what the carrier charges.
Exact rates vary by provider, catalog and order profile, so the useful step is to ask for a quote with every line item listed and compare complete quotes, not headline rates. Apparel fulfillment pricing walks through each line for clothing brands.
There is no single order count where outsourcing becomes right. There are clear signals.
For brands already packing a thousand or more orders a month, in-house vs 3PL past 1,000 orders compares the two in detail.
Ask how sizes are slotted, whether every pick is scanned, how fast returns are processed, how drops are planned, and who you call when something goes wrong. The last question matters more than most brands expect. A warehouse where your contact is in the building can look at the problem and fix it. 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.
The apparel 3PL checklist lists twenty questions to bring to any warehouse.
The best way to test any of these is to ask the warehouse directly, in writing, before you sign.
