A 3PL for Wholesale Orders: Picking One That Does B2B

By Martin Mecar, founderOctober 15, 20266 min read

Most third-party warehouses that court DTC brands are parcel operations. They are extremely good at putting one unit in one box and handing it to a courier, and that competence does not transfer to picking twelve cases, building a pallet and meeting a retailer's delivery window.

So the question is not whether to use a 3PL. It is whether the one you are talking to has ever shipped a purchase order to a retail distribution centre, and how you find out before you move your stock into their building.

When it is actually time

Moving too early is the more common mistake. The first dozen wholesale orders teach you what your case pack costs to build, where product gets damaged and how long the paperwork really takes, and a warehouse will not learn any of that on your behalf.

Three signals say it is time. Wholesale packing has stopped being an occasional batch and become a weekly block that displaces other work. Pallets are normal rather than exceptional, and you are building them badly in a space not designed for it. Or an account has arrived with delivery-window requirements you cannot personally guarantee while also running a business.

If none of those are true, the answer is a better routine rather than a partner — the sequence in wholesale fulfillment is most of it.

The questions that separate parcel shops from wholesale warehouses

Ask these early, in this order, and listen for hesitation rather than for the right answer.

  • Do you pick by case as a standard operation, or is everything eaches?
  • Do you build and wrap pallets in-house, and do you have a freight desk or a broker relationship?
  • Have you shipped to a retail distribution centre, and can you follow a routing guide?
  • Can you apply a carton label to a specification, including placement?
  • Can you receive a production run from my manufacturer directly, and what does that cost?
  • Do you support hold-and-release, so an order sits until a buyer's ship window opens?
  • Can you send an advance shipping notice, and can you handle a trading partner connection if an account demands one?

A warehouse that does wholesale answers all of these without asking what you mean. One that does not will start describing their DTC pick rates. That is not a scandal; it just means they are the wrong building for this channel.

The connection question deserves its own note: if you already have, or expect, an account that trades electronically, the warehouse has to be part of that plan. EDI on Shopify explains what that involves for a small brand.

How the pricing actually works

The quote will be a menu, not a rate, and the lines matter differently for wholesale than for DTC.

ChargeWhat drives itWholesale impact
ReceivingPallets or cartons inLow, a few times a year
StoragePallet positions per monthModerate and predictable
PickPer order, per line, per unitWatch this one
Pack and materialsCartons, wrap, labelsModerate
Special projectsAnything unusualWhere surprises live

The pick line is where a DTC-shaped contract bites. If picking is quoted per unit, a case of six costs six picks, and a five-case order costs thirty picks for what is physically five movements. Ask for case picking to be quoted per case. A warehouse used to wholesale offers that without being pushed.

Special projects is the line that covers re-packing, building assorted cases, applying labels that were not in the original scope and anything a routing guide demands. Get an hourly rate written down, because you will use it.

Onboarding: the six weeks before the first order

Plan for six weeks between signing and the first wholesale order going out cleanly. Brands that plan for one week ship their first order late and blame the warehouse.

The work in those weeks is mostly data. Every SKU needs a code that matches between your store, your warehouse and your invoices. Every SKU needs dimensions and weight, both per unit and per case, and they need to be measured rather than estimated because the warehouse will quote freight from them. Every case needs a defined pack configuration, and it needs to match what is physically on your shelves — the numbers you settled when designing your case pack packaging.

Then write the wholesale work instruction: a one-page document that says how a wholesale order differs from a DTC order in your account. Which packing slip template, which carton label, which cartons, what to do with a short pick, who to call. Warehouses run on documents like this, and the absence of one is why the first shipment goes out in mailers.

Finish with a test order to yourself or to a friendly account. Receive it, open it, and photograph everything that is wrong.

Keeping two channels in one building

Once your stock is in a warehouse, the DTC and wholesale channels draw from the same pool, and the allocation problem you had on a kitchen shelf becomes an allocation problem in racking.

The usual answer is virtual separation: the warehouse holds one physical pool, and you control what your store can sell by managing available quantities rather than by moving pallets around. That works provided you actually commit wholesale orders against stock when you confirm them, not when they ship. The discipline is described in wholesale inventory management, and it does not get easier when somebody else holds the boxes.

Watch the reporting boundary too. A warehouse invoice that lumps every pick together tells you nothing about what wholesale fulfilment costs per case, which is a number you need when you set minimums. Ask for order-level billing detail, or tag wholesale orders so you can separate them yourself.

What can still go wrong

Three failure patterns show up repeatedly in a first year with a wholesale-capable warehouse.

Receiving disputes. A production run arrives from your manufacturer, the warehouse counts fewer cases than the invoice, and neither of you was there. Insist on a receiving report with photographs, and have your manufacturer label cartons with counts.

Silent substitution. Someone in the building runs out of your inner cartons and ships the case in something else. It arrives looking like a different brand. Work instructions and photographs of a correct shipment prevent most of this.

Freight rebills. The warehouse books a pallet on your declared dimensions, the carrier measures it and rebills, and the charge appears on your account weeks later. The fix is measuring the built pallet, which is a shared responsibility and belongs in the instruction document. More on that in wholesale shipping.

None of these are reasons not to use a warehouse. They are reasons to spend the onboarding weeks properly.

Should the 3PL handle your DTC orders too

Usually yes, eventually, and not necessarily at the same time.

Running both under one roof means one inventory pool, one receiving process and one relationship, which is genuinely simpler. It also means picking a partner competent at two quite different jobs, and the warehouses strongest at pallets are sometimes mediocre at consumer parcels and the little presentation details that DTC customers notice.

If you have to choose, let the harder job decide. Parcels you can keep doing yourself for a long time. Pallets and routing guides you cannot.

And if the wholesale volume is not yet enough to justify any of this, the constraint is accounts rather than logistics. Paste your product link into WholesalePilot and look at the preview of retailers and distributors that stock similar products; warehouse decisions get much easier when the order flow is real.

Questions brands ask about a 3PL for wholesale orders

What minimum volume do warehouses want? Many DTC-focused ones want hundreds of orders a month, which a wholesale brand will never have. Wholesale-capable warehouses care more about pallet positions and predictability than order count, so ask on those terms.

Can a 3PL do my retail compliance labelling? The better ones can, as a special project with a per-carton charge. Get the specification from the retailer first and price it before you agree to the account.

Should I keep some stock myself? Keep a small buffer for samples, trade shows and emergencies. Having no stock in your own hands makes the small favours that win accounts impossible.

How long does switching warehouses take? Assume a season. Plan a move for the quiet part of your year, never before a gift season.
