What to Ask Before Signing a 3PL Contract: A Seller's Checklist

Introduction

Choosing a 3PL is a big decision. Your inventory, your customer experience, and a good part of your margins end up in someone else's hands. Most of the important details are not in the sales pitch, they are in the contract and the pricing sheet.

This checklist covers the questions worth asking before you sign, so you know what you are agreeing to and can compare providers fairly. It is general guidance, not legal advice, so it is a good idea to have any contract reviewed by someone qualified before you commit.

The Checklist at a Glance

1. Pricing and Fees

Fulfillment pricing is rarely one number. Ask for a full fee schedule and make sure you understand each line before you compare quotes.

• What are the receiving, storage, pick and pack, and packaging charges?
• How is storage priced, by pallet, shelf, bin, or cubic foot, and when does it start?
• Are there account minimums, monthly minimums, or onboarding and setup fees?
• What do returns processing, kitting, special projects, and labeling cost?
• Are there extra charges for oversized, fragile, or multi-item orders?
• How much notice is given before prices change?

2. Service Levels

Speed and accuracy should be written down, not just promised.

• What is the order cutoff time for same-day shipping?
• How quickly do inbound shipments get received and made available to sell?
• What accuracy rate does the warehouse aim for, and how is it measured?
• Is there a written service level agreement, and what happens if it is missed?

3. Inventory, Damage, and Liability

Things go wrong occasionally, so what matters is how the contract says they will be handled.

• Who is responsible for inventory that is lost or damaged in the warehouse?
• Is there a liability limit, and does it cover the real value of your product?
• How often is inventory counted, and how are discrepancies resolved?
• What insurance does the warehouse carry, and should you carry your own?

4. Technology and Visibility

• Does it integrate with your platform, such as Shopify, Amazon, or WooCommerce?
• Can you see inventory levels and order status in real time?
• How are inventory syncing errors detected and fixed?
• Are reports available for storage, orders, and shipping costs?

5. Contract Terms

This is the part people skim, and it is where problems tend to hide.

• How long is the initial term, and does it renew automatically?
• What is the notice period if you want to leave, and are there exit fees?
• Can you get your inventory back quickly if you leave, and at what cost?
• What happens to unpaid invoices or held inventory if there is a dispute?

6. Support and Room to Grow

• Will you have a named contact, and how fast do they usually respond?
• How does the warehouse handle peak season and sudden spikes in orders?
• Can it support new sales channels, kitting, or branded packaging as you grow?
• Are there storage or volume limits that could get in your way later?

Red Flags to Watch For

• A pricing sheet that is vague or only shows a few headline rates.
• Reluctance to put service levels or accuracy targets in writing.
• Long lock-in terms with heavy exit penalties.
• No clear answer on liability for lost or damaged inventory.
• Poor communication during the sales process, which rarely improves after signing.

Frequently Asked Questions

Should I sign a long-term contract with a 3PL?

It depends on your confidence in the provider. Shorter initial terms or clear exit conditions reduce risk, especially if it is your first time using a 3PL.

What are the most common hidden fees in fulfillment?

Account minimums, onboarding and setup charges, returns handling, special projects, and surcharges for oversized or multi-item orders are common ones to ask about.

Do I need a lawyer to review a 3PL contract?

It is often worth having a qualified professional review it, particularly the liability, term, and termination sections, since they have the biggest impact if something goes wrong.
