3PL pricing looks straightforward on paper. Then the first invoice arrives.
According to industry data, the average monthly minimum fee increased from $337 to $517 in 2025 — a 53% jump. And that's just one fee. Here are the 7 hidden charges that quietly drain your margins.
1. Long-Term Storage Fees
What it is: Extra charges when inventory sits longer than 30, 60, or 90 days.
How much: 1.5x to 3x your standard storage rate.
Why it hurts: 48.6% of warehouses now charge long-term storage fees, up from 23% the year before. If you have slow-moving SKUs or seasonal products, these fees stack fast.
How to avoid: Ask for the long-term storage policy upfront. Negotiate a 90-day threshold instead of 30. Better yet, find a 3PL that doesn't charge them.
2. Monthly Minimums
What it is: A floor you pay regardless of order volume.
How much: $500 to $3,000/month average.
Why it hurts: New brands and seasonal businesses get crushed. You pay the minimum even in slow months.
How to avoid: Negotiate minimums down or waived for the first 3-6 months. Some 3PLs offer no-minimum pricing for smaller brands.
3. Peak Season Surcharges
What it is: Q4 markup on fulfillment fees (October through December).
How much: 10% to 30% on top of normal rates.
Why it hurts: These often come with little notice, making it impossible to build into your pricing. Your busiest sales months become your thinnest margins.
How to avoid: Get peak surcharges capped in writing during contract negotiation. Ask for specific dates and percentages.
4. Shipping Markups
What it is: The 3PL adds margin on top of carrier rates.
How much: 5% to 25% markup on actual shipping costs.
Why it hurts: Shipping is usually your biggest fulfillment expense. A 15% markup on $50,000/month in shipping = $7,500 lost.
How to avoid: Ask if they pass through actual carrier invoices or mark up. Request to see a sample shipping invoice. Better: use your own carrier accounts.
5. Receiving Complexity Fees
What it is: Extra charges for floor-loaded containers, mixed-SKU pallets, or "non-standard" inbound shipments.
How much: $50 to $75 per container or pallet that requires breakdown.
Why it hurts: If you import from overseas, most of your containers are floor-loaded. This fee hits every single shipment.
How to avoid: Get receiving pricing in writing for YOUR specific inbound types. Don't accept generic "per pallet" quotes if you ship containers.
6. Technology & Account Management Fees
What it is: Monthly charges for WMS access, integrations, or a dedicated account manager.
How much: $200 to $1,000/month for tech; $500 to $2,500/month for account management.
Why it hurts: These aren't in the fulfillment quote. They show up as separate line items.
How to avoid: Ask explicitly: "What technology fees exist? Is account management included or extra?"
7. Exit & Inventory Removal Fees
What it is: Charges to get your inventory back if you leave.
How much: $2 to $5 per unit for packing and shipping out, plus carrier costs.
Why it hurts: Bad 3PL relationships happen. If it costs $10,000 to leave, you're trapped.
How to avoid: Get exit terms in writing before signing. Negotiate reasonable removal fees and notice periods.
How to Spot Hidden Fees Before Signing
- Request a sample invoice from an existing client — not a quote, an actual invoice
- Get a custom quote using your real order data from last month
- Ask "what else?" after every fee they list
- Read the contract — every word, especially the fine print on rate changes
- Benchmark 3 providers minimum before deciding
The Real Cost of Hidden Fees
A brand doing 5,000 orders/month with "competitive" $3.50/order fulfillment rates discovered they were actually paying $5.20/order after:
- $750 monthly minimum (hit in slow months)
- 15% shipping markup
- $500/month "technology fee"
- Peak surcharges in Q4
That's $102,000/year more than quoted.
