How to compare 3PL rate cards and quotes apples to apples

Why headline rates can't be compared#

Headline rates can't be compared because the order fee is one of about ten fee categories. Quotes also define fees differently: one order fee may include the first pick, packaging and an insert, another only order handling^3,5.

In 3PL Hub's 2026 pricing report, one publisher's dataset of requests for proposal (RFPs) run from 2023 to 2026, the priciest quote in the median RFP was 22% above the cheapest for identical work¹. Its cost model leaves out B2B fees, minimums, setup and courier rate cards, which the report says typically widen real spreads; the report's rate-card medians do include a B2B order fee¹.

For most direct-to-consumer (DTC) brands that ship on the 3PL's carrier accounts, postage is the largest share of total 3PL spend. In about nine in ten of Implentio customers' 3PL contracts, small-parcel postage is on the 3PL's invoice, so a comparison without shipping leaves out the largest cost. A pricing structure unlike the others isn't a warning sign by itself; check instead whether the quote is complete.

How to compare 3PL rate cards, step by step#

Run these six steps in a spreadsheet on one month of your own data: orders by units per order, inventory, inbound, returns and a sample of real shipments^2,6. They cover DTC parcel fulfillment; price B2B lines separately.

1. Get every quote complete, with definitions and assumptions#

A complete quote is the full rate card, not a summary, plus the fee definitions in the contract or statement of work (SOW)^2,7. It also states the volumes the quote assumes, any right to reprice if you miss them, and how long its rates are valid⁷. If your RFP used a pricing template, still ask for the full card, so lines that don't fit aren't dropped.

Treat a blank fee as unknown, not zero: ask the bidder to price it or confirm in writing that it isn't charged. For hourly or "as needed" lines, get in writing the rate by role, the minimum billing increment, when overtime applies, and the expected hours or quantity for your profile. Why the cheapest quote often isn't: hidden fees, minimums and assumptions lists the fees that tend to go missing.

2. Map every line to the same fee categories#

A line-item map is a comparison spreadsheet that places every fee from every quote in one shared list of categories⁴. Use the ten categories from How 3PL pricing works: an overview of the rate card as rows and each quote as a column, as in the template below.

Note each line's scope as you place it: one 3PL's order fee may include packaging, an insert or the shipping label, while another bills them separately. Some cards also combine categories, such as account and technology fees on one line. When one quote bundles work, move the other quotes' matching lines into the same row.

3. Convert each fee to your own units#

Price each fee on your own volumes in its own unit; rates in different units can't be compared directly.

Pick and pack. Two structures are common: an order fee that includes the first pick plus a fee per additional unit, or a lower order fee plus a pick fee on every unit. Among Implentio customers' 3PL contracts where picks can be classified, the two are about equally common (roughly 40–50% each). Price orders of 1, 2 and 3 units under each quote with the same scope, and ask whether additional picks are counted per unit, line or SKU⁵. All-in prices (one rate per order for set tasks, usually excluding postage) can still bill units beyond a set count, so get the cap and the overage fee in writing.

Storage. Price your actual inventory under each quote's unit (pallet position, bin, cubic foot, square foot or location) and count method (snapshot, daily average, peak or prorated, and any charge at receipt); Storage priced per pallet, per bin/shelf, per cubic foot, per square foot or per location gives the break-even rule.

Receiving. Convert per-pallet, per-carton, per-unit, per-SKU, per-container, per-receipt or hourly rates to your inbound profile: pallets, cartons, floor-loaded containers and SKUs per shipment. For hourly lines, use the bidder's written hours estimate, and ask whether two workers for one hour bill as one hour or two.

Packaging and returns. Estimate per-box or at-cost packaging from your own box mix and the bidder's box prices and any markup, not its average. Price returns on your own return count and extra units under each quote's basis (per return plus additional units, or per unit), and ask whether rates differ by return type or condition.

4. Price shipping on the same shipments#

Give every bidder the same sample of real shipments (weights, packed dimensions, destinations, services) and ask for the billed amount per shipment from the warehouse it would use, with surcharges itemized. Record each quote's basis: carrier cost, cost plus a markup, the 3PL's own rate card, or your own carrier account⁶. A 3PL's own rate card shows no carrier cost on the invoice, so compare billed amounts, not quoted discounts.

If a bidder won't price the sample, ask for its full shipping rate card and the divisor on each service, and price the sample yourself. A bidder that gives you neither has left its shipping price unknown.

Ask which DIM divisor applies on each service. In the 3PL rate cards we review, we see 139 on some services and divisors from 166 up to about 250 on others. Ask which boxes the bidder would use, since they set the dimensions it declares for dimensional weight; a carrier can still measure different ones. See How 3PLs bill shipping: pass-through, markup or the 3PL's own rate card and What is dimensional (DIM) weight, and how is it calculated?

5. Add fixed fees, one-time fees and the minimum#

Add account and technology fees as billed, monthly or per order. Spread one-time fees (setup, onboarding, integration) over the same number of months for every quote, the shared initial term or one stated horizon³. If a bidder waives setup, check whether the cost reappears in other lines or the minimum^2,6.

Describe each monthly minimum by which fees count toward it (pick and pack only, all warehouse fees, or postage too) and whether it credits. On a "greater of" floor you pay the higher of the minimum or the qualifying fees⁸; a charge that never credits belongs with fixed fees. A minimum that counts postage is usually set higher, so compare minimums as a share of the spend that counts, and test each in a slow month (Monthly minimums: how they're calculated, when they apply, how to negotiate them).

6. Compare total cost per order, then line by line#

Compare quotes first on fully loaded cost per order, with postage included even when it's on a separate invoice:

Warehouse fees here include amortized one-time fees and any minimum shortfall (see Calculating your true cost per order for adjustments, credits and one-time fees). Then compare category by category, since the biggest gaps show what to negotiate. If time is short, check in this order: shipping basis, pick scope, which fees count toward the minimum, storage measurement, returns categories, accessorials.

What a fair comparison looks like#

A fair comparison prices every quote on the same inputs and writes down every assumption, so each bidder can check its own column:

• the same month and shipment sample for every quote;
• every fee mapped, with its scope noted, and blanks resolved in writing;
• hourly lines priced on the bidder's estimate, one-time fees over one term;
• each minimum described by what counts, and tested in a slow month;
• assumptions listed under the table.

Before you sign, check that the contract's rate schedule and definitions match the quote you compared. For price levels, see What do 3PLs charge?
