5 Things to Look Out For Before You Sign Your 3PL Contract

The patterns below show up across most supplier-favorable drafts. They are standard 3PL drafting, optimized for the people who wrote it.

Five things to check before signing.

Check whether Schedule 1 is actually populated.

This happens more often than it should. The body of the contract references the Charges schedule throughout, but the schedule itself is blank, or contains "to be agreed" placeholders.

What it costs: without a locked rate card, the supplier can quote any rate after signing. Combined with the unilateral price-amendment clause (see #4), they can raise prices on a short notice period. The deemed-acceptance language in most drafts means silence inside the notice window waives your right to dispute.

What to ask for: complete per-pallet storage rates, receiving fees, pick and pack rates by volume tier, kitting time plus per-unit, returns processing, full courier matrix with zones and weight breaks, every surcharge enumerated, minimum monthly, setup fee. Rates lock for the Initial Term.

3PL contracts almost always include an explicit termination charge, usually phrased as a flat rate per pallet on the estimated final month.

The line right after is the one to read carefully. Standard drafting reads something like: "any other reasonable costs incurred by the Supplier in connection with the termination of the Agreement as may be calculated by the Supplier in its sole determination."

Sole determination means the supplier picks the number with no cap, no veto, no documentation requirement, and no third-party benchmark. The defined per-pallet fee is the starting point. Whatever else the supplier writes on the invoice gets added on top.

What it costs: unquantifiable. Sign with this language and you've taken on an open-ended exit liability that sits on your balance sheet as a contingency you cannot size.

What to ask for: strike "sole determination" entirely. Replace with documented third-party out-of-pocket costs reasonably and necessarily incurred by the Supplier in connection with the termination, capped at one month's average Charges over the preceding 12 months, with invoices evidencing such costs.

Storage charges are calculated against your inventory volume. The question is how that volume gets measured.

Three common bases:

Daily average. Volume snapshot summed across days, divided by number of days.

Weekly average. Snapshot on a fixed day each week.

Maximum in the period. The single highest volume during the billing month sets the rate.

Maximum billing inflates the storage line in any month with volume volatility. A single day's surge (a big inbound, a Q4 buildup, a restock cycle) sets the storage rate for the whole month. Whatever your peak-to-average volume ratio is, that ratio shows up in your storage line every month. A brand whose peak month runs 1.5x its average pays a 50 percent storage premium every month of the year under maximum billing.

What it costs: multiply your true daily-average storage spend by your peak-to-average ratio minus one to size the monthly overcharge. Multiply by contract months for total exposure over the term. Beyond the direct overcharge, maximum billing means the supplier configures the warehouse around your peaks rather than your averages, which removes their incentive to help you optimize.

What to ask for: daily average. If the supplier refuses, weekly average. If they still refuse, cap the peak-vs-average premium at 15 percent.

The Service Levels schedule is often blank, or filled with soft language like "the Supplier shall use reasonable endeavours to perform with reasonable care and skill." This kind of drafting ensures there is never a measurable breach.

What it costs: leverage. Without defined SLAs, you cannot point to a specific failure when the supplier ships late, mispicks orders, runs 95 percent inventory accuracy, or sits on claims for weeks. You are stuck arguing "reasonable," which is unwinnable. The supplier can underperform indefinitely and you have no contractual remedy short of full termination, which costs you (see #2).

What to ask for: populated SLAs with specific numeric targets. Inventory accuracy at or above 99.5 percent on quarterly cycle counts. Order accuracy at or above 99.5 percent at SKU-line level. Same-day pick cutoff at a defined time. Damage rate at or below 0.2 percent. Claims response within a defined number of business days. Each SLA needs a measurement method, a service credit at defined thresholds, and a termination right on chronic failure (three misses in any rolling six-month period is a defensible trigger).

Tying chronic SLA breach to no-fee exit is the structural ask worth pushing on. If the supplier consistently misses the standards they themselves agreed to, you leave without paying the termination fee or serving the notice period. The supplier either commits to performance standards or signals they cannot meet them. Refusing the structure tells you what you need to know about whether they expect to perform.

The most operationally dangerous clauses in a 3PL contract govern what the supplier can do with your inventory during a dispute or non-payment.

Standard supplier-favorable drafting includes:

A lien clause. The supplier has a claim on your goods as security for any sums it claims, disputed or not.

A power of sale. After a short notice period (often 14 days), the supplier can sell your inventory to recover claimed amounts.

A move-stock clause. During an unresolved dispute, the supplier can relocate your inventory to a non-disclosed location, at your cost.

Together, these mean the supplier can take your inventory if you do not pay, even when you formally dispute the invoice. They can move your stock to a location you do not know about and bill you for the transport. None of this requires a court ruling.

What it costs: operational paralysis at the moment you most need control. The wrong invoice dispute can trigger a sequence where your inventory is suddenly inaccessible, in transit to an undisclosed warehouse, while you negotiate from a much weaker position.

What to ask for:

3PL contracts are almost always written by the 3PL, optimized for the supplier's position. Signed without redlines, they shift pricing power, operational risk, and exit cost asymmetrically toward the supplier.

Most of these are negotiable. None of the asks above is exotic. A half-win on each one materially changes the economic and operational profile of the contract you sign.

The math worth knowing before signing: total cost of leaving, total cost of staying, and how leverage shifts between you and your supplier if performance slips.
