Quick answer
There are four main 3PL pricing models: activity-based (you pay per pallet stored, order picked and parcel shipped), fixed (a flat monthly fee for an agreed scope), cost-plus (actual costs plus a management fee) or a hybrid. Activity-based suits most growing ecommerce brands, but the model matters less than your total cost per order, including shipping and minimums.
The cheapest quote on your desk is often the most expensive once surcharges, minimum spends and shipping are added. This guide explains how 3PL pricing models work, what goes into a 3PL quote, the costs that are easy to miss, and how to compare quotes on the same basis.

What are the main 3PL pricing models?
A 3PL pricing model is the way your third-party logistics contract turns warehouse work into a monthly bill. It decides how predictable your costs are and how they change as your order volume rises or falls.
| Model | How you pay | Best for | Watch out for |
|---|---|---|---|
| Activity-based (pay per use) | Per pallet or shelf stored, per order and item picked, per parcel shipped | Growing and seasonal brands | Costs climb quickly at peak; many small line items to check |
| Fixed (flat rate) | One monthly fee for an agreed volume and scope of work | Stable, predictable volumes | Paying for capacity you don’t use when volume drops |
| Cost-plus | Actual labour, space and materials, plus a management fee | Large or complex operations | Needs detailed reporting so you can verify the costs |
| Hybrid | A fixed base (such as dedicated space or staff) plus activity charges | Brands with special requirements | Harder to compare like for like against other quotes |
Most ecommerce 3PLs quote activity-based pricing, often with a monthly minimum spend. Fixed, cost-plus and hybrid models are more common for larger B2B and retail operations.
What fees are included in 3PL pricing models?
Whatever the model, most 3PL invoices are built from the same six types of fees:
- Receiving (inbound): checking stock in, charged per pallet, carton, unit or hour. Unloading containers is usually priced separately.
- Storage: per pallet, shelf or bin, usually weekly. Some 3PLs charge per cubic metre. Slow-moving stock drives this cost up.
- Pick and pack: a fee per order, plus a smaller fee for each extra item in the order.
- Packaging: cartons, satchels and void fill, either included in pick and pack or charged per item used.
- Shipping: carrier rates passed through to you, usually with the 3PL’s volume discount and sometimes a margin added.
- Account and system fees: monthly account management, software or integration fees.

From our experience
When we compared five 3PLs for an apparel brand shipping about 1,500 orders a month, their warehousing quotes were within A$23,000 a year of each other, but their shipping costs differed by A$57,000. Shipping made up 60–67% of each 3PL’s total cost, so the 3PL with the cheapest storage was not the cheapest overall. Comparing 3PL pricing models on storage and handling rates alone would have missed this.
What hidden costs and contract terms should I watch for?
Headline rates rarely tell the whole story. Check each quote and contract for:
- Minimum monthly spend: you pay the minimum even in slow months. In the comparison above, one of the five 3PLs set a A$4,000 a month minimum.
- Set-up, account management and integration fees: one-off or monthly charges that don’t appear in the per-order rate.
- Dimensional weight surcharges: if your product dimensions are wrong, carriers charge on volumetric weight you didn’t budget for.
- Ad hoc labour: returns, kitting and special projects charged by the hour, often without a cap.
- Exit costs: long notice periods and outbound pallet fees can make it expensive to move your stock later.
- Price increases: annual rate reviews and carrier surcharges passed through, sometimes with an admin fee on top.
Before you sign, ask each 3PL for a sample invoice for a client with a similar order profile. It shows how fees are actually billed. For more on this, read the hidden costs of using a 3PL.
How do I choose between 3PL pricing models?
- Under about 500 orders a month, or highly seasonal: activity-based pricing with a low or no minimum spend, so you only pay for what you use.
- Steady, predictable volume: a fixed or hybrid model can lower your unit cost and make budgeting simpler.
- Large or complex operations: cost-plus or hybrid, especially if you need dedicated space or staff.
Whichever model you choose, compare quotes on total cost, not headline rates:
- Pull 3–6 months of order data: order numbers, items per order, weights and delivery postcodes.
- Give every 3PL the same order profile and ask them to price it.
- Model the total annual cost for each 3PL, including storage, handling, packaging, shipping and any minimum spend.
- Check the contract terms (minimums, notice periods and exit costs) before you decide.
Whichever of the 3PL pricing models you choose, compare quotes on total annual cost using your own order data, not on headline rates.

Frequently asked questions
Can I renegotiate my 3PL pricing after signing?
Often, yes, especially if your volumes have changed. A quarterly business review or a move into a new volume tier is the best time to ask. Bring your order data so the conversation is about facts.
Is activity-based pricing always cheaper for small businesses?
Not always. It keeps costs low in quiet months, but busy peaks can cost more than a fixed fee, and brands with many slow-moving products can pay a lot in storage. Compare total cost across both busy and quiet months.
What is a typical management fee in a cost-plus model?
It varies with the size and complexity of the operation. Ask for it as a clear percentage or fixed amount, and make sure the 3PL itemises the labour and materials it is charging at cost.
How do 3PLs handle carrier rate increases?
Most pass carrier increases straight through, usually once a year. Check whether your contract allows the 3PL to add an admin fee or margin on top.
Do 3PLs charge to connect my online store?
Many charge a one-off set-up fee, a monthly fee, or both, for integrations with platforms like Shopify or Amazon. Ask whether the fee is per platform before you sign.
