Apparel 3PL Checklist

Twenty questions to ask any warehouse before you send it your inventory, with our answers.

How to Use This List

Ask every warehouse you are considering the same questions, in writing. Vague answers are an answer too.

    The five that matter most:

  • Who do I call when it is urgent?

    And are they in the building?
  • How are sizes and colors slotted?

    Mixed bins mean wrong sizes.
  • How fast are returns processed?

    Slow returns mean stuck stock and stalled exchanges.
  • How do you prepare for a drop?

    Ask what they need and how far ahead.
  • What is on the invoice?

    Ask for a sample.

The Questions, Grouped and Explained

Why each group matters for an apparel brand at volume.

People and support (questions 1 to 3)

Every warehouse has problems. What separates them is how fast a problem gets fixed. That depends on who you reach and whether they can see the problem. Ask where the account manager works, how requests are acknowledged, and whether support is outsourced.

Inventory and receiving (questions 4 to 6)

Apparel accuracy is decided before the first order. Ask how sizes and colors are slotted, how fast inbound is received, and what happens when a carton does not match the paperwork. A warehouse that mixes sizes in one bin will ship wrong sizes.

Picking, packing and shipping (questions 7 to 9)

Ask whether every pick is scanned, what the same-day cutoff is, and whether they will follow your packing instructions. For apparel, the packing instructions are part of the brand: folding, bags, stickers, inserts.

Returns (questions 10 to 12)

Apparel returns are constant. Ask how fast they are processed, whether you get return reasons by SKU, and whether the warehouse works with your returns app.

Drops, bundles and wholesale (questions 13 to 15)

Ask how the warehouse prepares for a drop, whether bundles can be built ahead, and whether it can ship wholesale orders to retailers from the same inventory.

Money and terms (questions 16 to 20)

Ask how storage is billed, how often you are invoiced, whether there is a minimum or a long-term contract, how shipping is billed, and how long onboarding takes.

How to Score the Answers

A simple scorecard makes quotes and conversations comparable.

Score each answer from 0 to 2. Zero means vague, missing or only verbal. One means clear but not shown. Two means clear, in writing, and shown to you on a visit or in a report.

ScoreWhat it looks likeExample
0Vague, deflected or only said on a sales call"We have great support"
1Clear and specific, but not yet shown"Requests are acknowledged within two hours"
2Clear, in writing, and shown to youYou met the account manager on the floor and saw the report

Weight the people and returns groups more heavily if your brand runs drops. A low score on support costs more during a launch than a slightly higher pick fee costs all year.

Red Flags

Answers that should make you slow down.

  • Nobody can tell you where your account manager works.
  • Support is a ticket form with no named person.
  • Sizes are stored together in mixed bins "to save space".
  • Picks are not scanned, or only some are.
  • Returns are processed "when we can get to them".
  • No sample invoice, or a price list with blanks.
  • A monthly minimum that is hard to get stated plainly.
  • A long contract with a costly exit.
  • No plan for drops beyond "we can handle it".

Running the Site Visit

You learn more in an hour on the floor than in a week of emails.

Ask to visit. A warehouse that welcomes you is a good sign. Bring this list and look for these things while you are there.

  1. Walk receiving. Ask to see how a factory carton is checked against an advance shipping notice.
  2. Look at apparel storage. Are sizes and colors in separate, labeled locations?
  3. Watch a pick. Is every unit scanned?
  4. Watch a pack. Ask to see packing instructions for another apparel brand.
  5. Walk returns. How long have the items in the returns area been waiting?
  6. Meet the person who would be your account manager, where they work.
  7. Ask what they would need from you before your next drop.

The Apparel Test Order

Before you sign, run orders that test what usually goes wrong.

Once the integration is connected, place test orders that stress the parts of apparel fulfillment where mistakes happen. Do this with any warehouse you are considering.

Test orderWhat it tests
Two sizes of the same styleSize-level slotting and scanning
Two colors of the same style in one sizeColor-level slotting
A four-item order with an insertMulti-item packing and your instructions
A bundle or gift-with-purchaseKitting rules
An order placed just before the cutoffSame-day shipping
A return of one size for an exchangeReturns speed and the exchange flow

Look at what arrives, not just the tracking. Is it folded and packed the way you asked? Did the right sizes ship?

Questions About Inventory Data and Your Portal

You will live in the warehouse's data every day. Ask to see it.

For an apparel brand, the dashboard is where you find out which sizes are running low, which returns came back, and which inbound shipments were short. Ask every warehouse to show you its portal with a real apparel account, not a demo screen.

  • Can I see inventory by variant, size by size and color by color?
  • Does inventory sync with my store, and how often?
  • Are receiving discrepancies shown with photos?
  • Can I see returns by style, size and reason?
  • What reports arrive every week without my asking?
  • Who explains the numbers when something looks wrong?

At OC3PL you see live inventory by SKU in your dashboard, receiving discrepancies are logged in your portal with a photo of every SKU, and your account manager sends weekly performance reporting covering service levels, shipping costs and inventory status. Returns come with monthly summaries by SKU and reason. See real-time SKU reporting.

Reference Calls

Talk to brands that already ship from the warehouse.

Ask each warehouse for references from apparel brands near your size. When you call, skip the general questions and ask about the moments that test a warehouse.

  • Tell me about the last time something went wrong. Who did you talk to, and how long did the fix take?
  • How did your last drop or promotion go?
  • How long do returns take to show back in stock?
  • Have wrong sizes or colors been a problem?
  • Has your invoice ever surprised you?
  • Would you choose the same warehouse again?

Listen for specifics. A reference who can name their account manager and describe a real problem being fixed is worth more than one who says everything is great.

Questions to Ask Yourself

The checklist works best when you know your own answers too.

A warehouse can only answer well if it knows what you need. Before you start, write down your own answers to these.

QuestionWhy it matters
How many orders a month, and how many on a drop day?Sets labor and capacity planning
How many active variants?Sets storage and slotting
What share of orders have more than one item?Drives pick cost and packaging
How many returns a month, and how fast do you refund?Sets returns capacity and policy
Which channels do you sell on, now and next year?DTC, Amazon, TikTok Shop and wholesale each need different handling
What does your packing look like?Folding, inserts and branded materials add touches
What went wrong with your last warehouse?Tells you which questions to weigh most

Brands that come to the conversation with these numbers get better quotes and better answers. See the apparel 3PL RFP template.

Questions Specific to Streetwear and Surf Brands

Add these if your brand lives on drops or seasons.

For streetwear and creator brands

  • How far ahead do you need a drop forecast, and what happens if it sells faster?
  • Can bundles and gift-with-purchase items be built before launch?
  • How do you handle orders that need to be canceled or held after a drop?
  • Can you pack branded mailers, stickers and inserts on every order during a spike?

For surf brands

  • Can you ship to surf shops and retailers from the same inventory as DTC orders?
  • How does storage change between the summer peak and the off-season?
  • How are wholesale purchase orders routed, labeled and palletized?
  • Can you store and ship larger items, such as boards or bulky hardgoods? Yes. Send dimensions and volumes so storage and shipping are planned before they arrive.

See streetwear fulfillment for LA brands and surf brand fulfillment.

What to Keep in Writing

Sales calls are friendly. Agreements are what count.

Ask for the answers that matter to be written into your agreement or service terms. That usually includes order accuracy, receiving turnaround, the shipping cutoff, inventory accuracy, returns processing time, and what happens when a target is missed.

Ask how each one is measured and reported, and whether the clock starts at order receipt or at label creation. See what an apparel brand should put in a 3PL service agreement and what is a 3PL SLA.

Common Questions

Size- and color-sorted slotting, a scan on every pick, fast receiving, returns processed within days not weeks, packing to your own instructions, a plan for drops, and an account manager you can reach on site.

Comparing headline rates instead of complete quotes, and not asking who answers when something goes wrong.

Yes. See how apparel is slotted, how returns are handled, and meet the person who would manage your account.

Enough to see real differences, usually three or four. Send each the same data and the same questions so the answers are comparable.

Run a month of your real orders through each price list, add storage for your real inventory, and divide by orders. Compare cost per order, then weigh the support answers.

Two sizes of one style, two colors in one size, a multi-item order with an insert, a bundle, an order just before the cutoff, and an exchange.

Order accuracy, receiving turnaround, the shipping cutoff, inventory accuracy, returns processing time, how each is measured, and what happens when a target is missed.

Yes. Come to Anaheim, see how apparel is slotted and packed, and meet the people who would run your account.

Ask about the last time something went wrong, who they talked to and how long the fix took, how their last drop went, how fast returns show back in stock, and whether invoices have surprised them.

For a brand shipping thousands of orders a month, a few weeks is normal: send data, get quotes, run calls and a visit, place test orders, check references, then agree terms. Rushing it usually means skipping the visit and the test orders, which are where problems show up.

Weigh support and returns most heavily. Meet both account managers in person, and choose the one you would rather call on the worst day of your next drop.

How far ahead a drop forecast is needed, what happens if it sells faster, whether bundles can be built before launch, how held or canceled orders are handled, and whether branded packing holds up during a spike.
