Two 3PL quotes can use completely different billing structures and still describe the same warehouse work. To compare them fairly, convert every fee into a common cost model based on your real order profile, SKU count, storage footprint and monthly volume.
Per-order fulfillment fees
A flat fulfillment fee per order is easy to model, but check what it includes. Some providers include the first pick, standard packing and basic materials; others separate each component.
Per-item pick fees
Per-item pricing matters when orders contain multiple units. A low first-pick fee can become expensive if every additional item adds another charge. Model average units per order rather than using only order count.
Hourly labor
Hourly fees are common for projects that are difficult to standardize, such as relabeling, quality checks, repacking, inventory remediation or unusual kitting. Ask whether labor is billed in minimum increments and whether supervision is separate.
Storage pricing
Storage may be billed per pallet, bin, shelf, cubic foot or location. A provider with a higher pick fee can still be cheaper if its storage model fits your inventory profile better. See our 3PL storage fee comparison.
Receiving fees
Inbound receiving can be billed per pallet, carton, container, unit or labor hour. The cheapest structure depends on how suppliers deliver inventory and how much counting or inspection is required. Our 3PL receiving fee guide covers the main structures.
Project and special-handling fees
Projects are often where ecommerce brands lose cost visibility. Define rates for kitting, inserts, barcoding, relabeling, photography, disposal, B2B prep and marketplace compliance before those tasks become urgent.
Monthly minimums
A minimum is effectively a fixed cost floor. It can be reasonable if the provider reserves labor and systems for your account, but it should be included in cost-per-order calculations for slow months. Read 3PL monthly minimums and account fees.
Example comparison
| Quote A | Quote B |
|---|---|
| $3.00 first order + $0.50 per additional item | $3.75 flat fee up to 3 items |
| Lower for single-item orders | May be lower for multi-item baskets |
| More sensitive to units/order | More predictable for common baskets |
The correct answer depends on your mix. Use historical orders rather than an “average order” if basket size varies significantly.
How to normalize a 3PL quote
- Choose a representative month.
- Enter orders, units per order, pallets/bins and inbound receipts.
- Add account fees, minimums, software and project work.
- Separate warehouse fees from postage.
- Calculate cost per shipped order.
- Repeat for a peak month and a low-volume month.
Use the 3PL cost calculator to model these scenarios, then compare the result with our 3PL fulfillment cost-per-order guide so fixed fees, shipping and exception costs are not omitted from the final decision.
FAQ
Which 3PL pricing model is cheapest?
There is no universally cheapest structure. The best model is the one that maps efficiently to your specific order and inventory profile.
Should packaging be included in pick-and-pack?
Do not assume it is. Confirm which materials are included and how specialty cartons, inserts and void fill are billed.
How often should quotes be re-modeled?
Re-run the model when order volume, SKU count, average basket size, storage footprint or carrier mix changes materially.
