How to review a 3PL or fulfillment agreement before you sign
What to check in a 3PL or fulfillment agreement before signing: volume minimums, storage and accessorial fees, inventory liability, shrink allowances, exit terms and data access — with the fix to ask for.
A third-party logistics agreement is the contract that holds your inventory, ships your orders and bills you by the touch. For an ecommerce or distribution business it is often the largest vendor relationship after the product itself, and it is the hardest to leave: moving pallets is slow, expensive and visible to customers.
The risk in a 3PL agreement is less about one bad clause than about the gap between the quoted rate card and the contract. The rate card shows pick-and-pack. The contract decides minimums, accessorials, who pays for shrink, what happens when a shipment is lost, and how many months of notice an exit takes. Check these in order.
Who usually signs it: The owner or head of operations of an ecommerce, DTC or distribution business; in central Ohio, often one shipping from the Rickenbacker or Groveport warehouse corridor.
Columbus is a logistics city, and 3PL agreements from the Rickenbacker and Groveport corridor are among the contracts central Ohio owners send most often. Vendor agreement review for Columbus businesses →
The clauses to check, in order
- 01
Minimum volume or minimum monthly fee
Why it matters: A minimum turns a variable cost into a fixed one. In a slow quarter you pay for orders you did not ship.
What to ask for: No minimum in year one, or a minimum set below your trailing-three-month average, with a right to renegotiate if volume falls for two consecutive months.
- 02
Accessorial and storage fees outside the rate card
Why it matters: Receiving, kitting, returns, long-term storage, "special handling" and re-labeling are billed per event at rates that sit in an appendix, not on the quote.
What to ask for: Every billable event listed with its rate in the agreement, a cap on storage rate increases, and 60 days' notice of any new fee.
- 03
Inventory liability and shrink allowance
Why it matters: Many 3PLs cap their liability for lost or damaged inventory at a low per-unit figure and allow a shrink percentage before any liability attaches.
What to ask for: Liability at your landed cost, a shrink allowance you have actually measured, and an annual physical count with discrepancies reconciled in writing.
- 04
Term, auto-renewal and exit timeline
Why it matters: A multi-year term with auto-renewal and a 90–180 day exit, combined with the time it takes to move inventory, can lock you in for a full extra year.
What to ask for: A one-year initial term, 60–90 days' notice, and a written transition plan: inventory released within a set number of days of notice, at a defined cost.
- 05
Lien on inventory
Why it matters: A warehouseman's lien lets the 3PL hold your goods until disputed invoices are paid. In a billing dispute, your inventory becomes the hostage.
What to ask for: A lien limited to undisputed, overdue invoices, with a dispute process that releases goods on escrow or partial payment.
- 06
Service levels without remedies
Why it matters: An order-accuracy or ship-by-time target with no credit or termination right is a goal, not an obligation.
What to ask for: Defined accuracy and on-time metrics, monthly reporting you can audit, credits for misses, and a termination right after repeated misses.
- 07
Data and system access
Why it matters: Your order, inventory and customer data sit in the 3PL's WMS. Without an export right you leave blind.
What to ask for: Full data export on request and at exit, in a standard format, at no charge.
Before you sign: the checklist
- Compare the rate card to the fee schedule in the agreement — list every fee that is not on the quote.
- Find the minimum and compare it to your actual monthly volume.
- Read the liability clause for lost or damaged inventory and the shrink allowance.
- Write down the term, the notice window and the time to get inventory out.
- Check for a lien on inventory and how disputes are handled.
- Confirm service levels have a remedy.

Questions
What is a reasonable shrink allowance in a 3PL contract?
It depends on your product, packaging and velocity, and the honest answer is that most owner-operators have never measured it. Before agreeing to a percentage, run a physical count against the 3PL's inventory report. An allowance you have not measured is a liability you have not priced.
How long does it take to leave a 3PL?
Read the agreement, not the sales rep: the notice period plus the time the 3PL is allowed to take to release inventory, plus the time your next warehouse needs to receive it. A review flags all three dates so the exit can be planned before the renewal window closes.
Does Sidecar review 3PL agreements or only SaaS?
Any vendor agreement: 3PL and fulfillment, freight, SaaS, agency MSAs, leases, supplier terms. Upload the agreement and its rate card or appendices as attachments, and the review reads them together.
