What Should a Pick-and-Pack Fee Structure Include?

A fair pick-and-pack fee structure separates three costs — the labor to pick each item, the labor to pack and seal the order, and the packaging materials themselves — and prices each one separately, usually as a flat fee per order plus a smaller fee for each additional unit. If your 3PL bundles all three into one unexplained line item, you have no reliable way to tell whether you are paying for efficient fulfillment or for someone else's overhead.

What a Fair Pick-and-Pack Fee Structure Looks Like

Most defensible pick-and-pack fee structures break down into three line items on the invoice, not one. Each should be visible and each should move independently when your order profile changes.

• Base order fee: covers picking the first item and preparing the order, usually quoted as a flat rate per order shipped.
• Per-additional-unit fee: a smaller charge for each extra SKU or unit picked into the same order, since the marginal labor cost of a second item is lower than the first.
• Packaging materials: boxes, mailers, void fill and tape, either passed through at cost or marked up by a disclosed percentage — not folded invisibly into the order fee.

If a 3PL cannot show you these three numbers separately, ask why. A single blended rate makes it impossible to compare quotes across providers or to catch a rate increase buried in a renewal.

Common Add-Ons That Inflate a Pick-and-Pack Fee

The base rate is rarely the whole story. Fee structures expand through add-ons that are technically separate line items but functionally raise your real cost per order.

• Kitting and bundling fees for multi-item sets assembled before shipping.
• Special handling fees for fragile, oversized or hazardous items.
• Minimum order fees that apply when a shipment falls below a set unit count, effectively raising the per-order cost for small or split orders.
• Returns processing fees charged per returned unit, separate from outbound pick-and-pack.
• Peak season surcharges applied across Q4 without a cap written into the contract.

None of these are unreasonable on their own. The problem is when they are not itemized in the rate card you sign, and only surface on the first invoice after a busy month. Brands that stay on one contract for years without renegotiating these line items are the ones most exposed to this kind of creep — a pattern covered in more depth in why locking into a single 3PL is costing your brand money. A separate breakdown of the specific add-on charges that erode margin over a full year is available in the piece on the fee structure quietly reshaping your fulfillment margins.

A Worked Example: Pricing a 1,000-Unit Month

Here is a worked example, not a market average, to show how the same order volume produces different real costs depending on how the fee is structured.

In this example, Scenario B looks simpler on the rate card but costs more once the real labor is accounted for, and the blended fee gives you nothing to renegotiate against as volume grows. To run the same comparison against your own order mix, shipping zones and unit economics, use the fulfillment cost calculator before you sign anything.

What Belongs in the Contract, Not Just the Rate Card

A pick-and-pack rate is only half the agreement. The contract itself should state how often rates can change, what notice period applies before an increase, whether minimum monthly fees apply if volume drops, and what it costs to exit if the relationship does not work out. None of this shows up on a pricing sheet, but all of it determines what you actually pay over a 12-month period. Ask for these terms in writing before you negotiate the per-unit rate down, since a low headline fee attached to a restrictive contract is not actually a lower cost.

How SPS Prices Fulfillment Under One Contract

SPS Fulfillment is an Agentic 4PL: one contract covers customs, import, freight, warehousing, and fulfillment — pick, pack, ship, and returns — across the US–EU corridor, with specialist operators handling each piece instead of SPS owning warehouses or trucks itself. From 2023 to 2025, while operating as a 3PL, SPS bootstrapped past $500K in GTV, served about 150 brands, and shipped more than 30,000 packages. Clients work from a live platform covering orders, inventory, multi-carrier rate comparison, tracking, invoices, and a Shopify app, so pick-and-pack costs sit alongside freight and customs costs in one place rather than across separate vendor invoices.

Frequently asked questions

Is a per-order fee or a per-unit fee better for a pick-and-pack contract?

Most fair structures use both: a base fee per order to cover the first pick, plus a smaller per-unit fee for additional items in the same order. A pure per-unit fee with no order base can undercharge for small orders and overcharge for large multi-item ones.

Should packaging materials be included in the pick-and-pack fee?

Packaging should appear as its own line item, either billed at cost or with a disclosed markup, rather than folded into the pick-and-pack rate. This lets you catch a packaging cost increase separately from a labor rate increase.

What is a reasonable minimum order fee?

There is no single market figure, since minimums depend on your average order size and the 3PL's labor cost base. The important thing is that the minimum and the unit threshold that triggers it are written into the contract, not applied retroactively on an invoice.

How often should a pick-and-pack fee be renegotiated?

Review it at least annually, and immediately after any sustained change in order volume or average units per order, since both affect the real labor cost behind the fee. A contract without a defined review point tends to lock in outdated rates in your 3PL's favor.

A pick-and-pack fee is one of the few fulfillment costs you can audit line by line before you sign anything, provided the rate card actually separates picking, packing, and packaging instead of hiding them in a single number. If you are weighing whether your current structure still fits your order volume, or want fulfillment priced alongside customs and freight under one contract, you can get started with SPS and see the numbers side by side.
