Most 3PL contracts in Australia are written by the 3PL's lawyers, optimised for the 3PL's risk profile. That's normal — every commercial template starts somewhere. What's not normal is brands signing them as-is. Across 47 audited contracts we've reviewed since 2024, the median brand could have negotiated $1,180/month off their bill simply by pushing on 4–5 of the clauses below.
This is the list, ranked by what we see costing brands the most. For each one we've included the language we typically see, why it matters, and how we'd push back. Severity tags reflect what we observe in audits — high means we frequently see real money lost, low means it's housekeeping.
| # | Red flag | Typical annual cost | Severity |
|---|---|---|---|
| 1 | Cost-plus shipping with hidden margin | $3,000–$15,000 | High |
| 2 | Uncapped annual rate increase | $2,000–$8,000 | High |
| 3 | Long-term storage trigger at 90 days, 2× multiplier | $1,500–$6,000 | High |
| 4 | Asymmetric indemnity / liability cap | Catastrophic | High |
| 5 | 12-month auto-renewal with 90-day notice | Lock-in | High |
| 6 | "Reasonable fees" / open-ended pass-throughs | $1,000–$5,000 | Medium |
| 7 | Minimum monthly fee with no soft-launch protection | $1,000–$4,000 | Medium |
| 8 | Asymmetric force majeure | Variable | Medium |
| 9 | Inventory shrinkage threshold below 0.25% | $500–$3,000 | Medium |
| 10 | Exclusive supplier / non-compete clauses | Strategic | Medium |
| 11 | Data ownership ambiguity | Switching cost | Medium |
| 12 | Vague SLAs without remedies | Variable | Low |
| 13 | Insurance minimum below $5M | Risk exposure | Low |
The thirteen, in order of cost.
Cost-plus shipping with hidden margin.
High severity · most commonThe 3PL bills you "carrier rates plus a small handling fee" but never shows you the actual carrier invoice. The "small fee" is 8–18% of the rate, often layered on top of the carrier's own margin. We see this in roughly 60% of audits.
Uncapped annual rate increase.
High severity"Rates may be adjusted annually with 30 days written notice." That's it. No cap, no benchmark, no negotiation trigger. We've seen 3PLs push 9–14% increases on brands with this language while CPI was 3%.
Long-term storage triggers at 90 days, 2× multiplier.
High severityInventory that sits over 90 days flips to "long-term storage" billed at 2× or 3× the standard rate. This is reasonable in principle — slow inventory hurts the 3PL's space turn. But the trigger is too short for many AU brands (especially those with seasonal product) and the multiplier is too high.
Asymmetric indemnity / liability cap.
High severity · catastrophic if it bitesThe contract caps the 3PL's liability at "fees paid in the previous 3 months" or "$10,000" — but requires you to indemnify the 3PL for any third-party claim, with no cap. You carry the entire weight of customer claims, regulator action and IP issues; the 3PL carries one quarter of fees.
12-month auto-renewal with 90-day notice window.
High severity · lock-in mechanicThe contract auto-renews for 12 months unless you give 90 days notice. Miss the window and you're locked in for another year — at the time of year that's hardest to switch, usually right before peak season.
"Reasonable fees" / open-ended pass-throughs.
Medium severityThe contract reserves the right to charge "reasonable fees" for any service "not specifically enumerated" in the rate card — pallet repair, label re-print, sample-pull, special projects, fuel surcharges. "Reasonable" is whatever the 3PL invoices.
Minimum monthly fee with no soft-launch protection.
Medium severityThe 3PL requires a minimum monthly spend (often $3,000–$8,000) from day one — even while you're still onboarding, integrating systems, and have no inventory in the warehouse yet. We've seen brands pay 2–3 months of minimums before a single order ships.
Asymmetric force majeure.
Medium severityThe 3PL is excused from performance during a force-majeure event (pandemic, natural disaster, transport strike) but you're still required to pay storage. Or worse — they get to suspend the SLA but you can't terminate even if performance has been zero for months.
Inventory shrinkage threshold below 0.25%.
Medium severityThe 3PL accepts no liability for inventory loss up to a stated threshold. Industry norm is 0.25% of inventory value. We've seen contracts at 1.5% — which on $500K of stock is $7,500 of "free shrinkage" for the 3PL before they owe you anything.
Exclusive supplier / non-compete clauses.
Medium severityYou're prohibited from using any other 3PL during the term, including for new geographies, channels, or product lines. This is sometimes legitimate (dedicated capacity) but more often it's a strategic lock-in dressed up as "operational consistency".
Data ownership ambiguity.
Medium severity · switching taxWho owns your inventory data, order history, customer addresses, SKU master? If this is silent or vague, the 3PL can charge you to extract your own data when you switch — we've seen "data extraction fees" of $5,000–$25,000 quoted at termination.
Vague SLAs without remedies.
Low severity but irritating"99% pick accuracy" with no definition of how it's measured, no reporting cadence, and no remedy if it isn't met. Without a defined remedy (service credit, escalation right, termination right) the SLA is decorative.
Insurance minimum below $5M.
Low severity but increasingly importantThe 3PL's minimum insurance — public liability, warehouse liability, transit insurance — sits below what your inventory at peak is worth. If your inventory is worth $800K at peak season and the 3PL carries $1M warehouse liability, a partial loss covers you, but a full loss leaves the recovery in their balance sheet, not their insurer's.
"You don't have to win every clause. Win the four expensive ones — shipping margin, rate increase cap, long-term storage, mutual indemnity — and you'll come out ahead of 80% of the brands we audit."
