A 3PL contract should answer six questions in plain words: how long you are committed, exactly what you will be charged, what performance the provider promises, who pays when something goes wrong, how either side can leave, and who owns your data and inventory records. If any of those is vague, resolve it before you sign. This checklist walks through each one so you can read a fulfillment agreement with confidence. It is general guidance, not legal advice, so have your own lawyer review the final document.
The six areas to check
1. Term, renewal and minimums
Check the initial term, how the contract renews and how much notice you must give to stop it. A common trap is automatic renewal for another full term with a notice window you can easily miss, so put the date in your calendar. Look for any minimum commitments (volume, storage space, monthly spend) and what happens if you fall short. A brand with seasonal volume should compare the minimums against its slowest month, not its average.
2. Fees: every charge, by name
Contracts that read cleanly on the headline rate can hide costs in the schedule. Make sure the rate card lists each charge by name and says when it applies. Typical categories include onboarding or setup, receiving, storage, pick and pack, packaging materials, shipping and postage handling, returns processing, special projects, and any minimum monthly charge. Ask what triggers a price change and how much notice you get. Our guide to 3PL pricing in Canada explains each fee type and how to model your total cost. Build a worked example with your own order profile and ask the provider to confirm the invoice it would produce.
3. Service levels (SLAs)
A service level agreement turns “we are fast and accurate” into numbers you can measure. For each commitment, check four things: what is measured, how it is measured, how often it is reported, and what happens if it is missed.
Common SLA topics include:
- Receiving time: how long from dock arrival to available inventory.
- Order cutoff and ship time: the cutoff for same-day processing and the time to ship after release.
- Order accuracy: the share of orders shipped correctly, and how errors are counted.
- Inventory accuracy: how counts are checked, and how discrepancies are reported and resolved.
- Returns turnaround: time from receipt to restock or disposition.
- Reporting and support: which reports you get and how quickly questions are answered.
Targets mean little without reporting. Ask to see a sample report, and read our guides on warehouse KPI scorecards and inventory accuracy and SLA reporting. Check, too, whether remedies are realistic: a service credit is only useful if it is actually paid when a target is missed.
4. Liability, loss and insurance
This is the clause most brands skim and most regret. Find out who is responsible if inventory is lost, damaged or shipped in error, and what the maximum payout is. Some contracts limit the warehouse’s liability to a small amount per pound or per unit, or to a multiple of recent fees, which can be well below your inventory’s replacement cost. Ask what insurance the provider carries, what it covers and whether you should hold your own coverage for stored inventory. Our article on who covers inventory in a 3PL warehouse explains how this usually works. Ask what counts as loss: shrinkage, damage in handling, carrier loss and customs delays can each be treated differently.
5. Termination, exit and inventory return
Read the exit terms before you need them. Check how much notice either side must give, whether there are early-termination fees, how and when your inventory is returned or transferred, who pays for that move, and what happens to unpaid invoices. A provider that makes leaving easy is usually confident about staying. Also confirm what happens if the 3PL changes ownership or moves facilities.
6. Data, systems and confidentiality
Your order history, SKU data, customer information and inventory records belong to your business. Confirm that you can export them, that access to your data ends when the contract does and that customer information is handled under the privacy rules that apply in the countries you ship to. Also check integration commitments, such as which systems connect, who builds the connection and who pays for changes. Read our guide to 3PL ERP integration for what to define in writing.
Other clauses worth a second look
- Products handled: what the provider will not store or ship (for example hazardous or perishable goods), and what happens if you add a new product type. Evolution Fulfillment, for example, does not handle dangerous goods or perishables.
- Cross-border responsibility: who handles customs documents and duties on shipments to another country.
- Peak-season terms: capacity commitments, cutoffs and any seasonal surcharges.
- Subcontracting: whether the 3PL can hand your inventory to another warehouse or carrier without telling you.
- Audit rights: whether you can inspect the facility and count your inventory.
- Dispute process: how disagreements about invoices or errors are raised and resolved.
What is usually worth negotiating
Standard 3PL agreements are written to suit the provider, so it is reasonable to ask for changes, especially for brands with growing or seasonal volume. The points that most often matter:
- Minimums: whether a monthly minimum can start lower and step up as volume grows, or be measured over a quarter instead of a month.
- Rate reviews: how often prices can change, how much notice you get and whether a cap applies.
- Notice periods: a shorter notice window gives you flexibility if the relationship is not working.
- Liability limits: whether the cap can be raised for high-value products, or whether you can declare a higher value and insure the difference.
- SLA remedies: a clear credit or corrective-action process when a target is missed.
- Exit support: an agreed timeline and cost for returning or transferring your inventory.
Put every agreed change in the signed document. A promise made during sales calls carries little weight if the contract says something else.
Where the contract fits in the selection process
A contract is the last step, not the first. Compare providers with our RFP question list, then use this checklist to review the draft agreement of the provider you pick. Once signed, our onboarding checklist shows what to prepare so you go live smoothly.
Ask for the contract early
Whichever provider you choose, review its terms in writing before committing. If you are considering Evolution Fulfillment, tell us about your products, channels and monthly volume, see which of our fulfillment services you need, and we will respond with a quote. Ask for the contract terms in writing as part of that conversation. Request a fulfillment quote.
Frequently asked questions
What should be in a 3PL contract?
A 3PL contract should state the term and renewal rules, every fee and when it applies, measurable service levels with reporting and remedies, liability and insurance terms, termination and exit conditions, and who owns your data. Anything left vague in these areas is worth clarifying before you sign.
What is a 3PL service level agreement (SLA)?
A 3PL SLA sets measurable performance targets, such as receiving time, order cutoff and ship time, order accuracy, inventory accuracy and returns turnaround. A good SLA says how each target is measured and reported and what the provider does if it is missed.
How long is a typical 3PL contract?
Terms vary by provider and by the size and complexity of your account. Whatever the length, check how it renews, how much notice you must give and whether any exit fees apply. Ask the provider for its standard term in writing and compare it with others.
Who is liable for lost or damaged inventory in a 3PL warehouse?
It depends on the contract. Many agreements limit the warehouse’s liability to a defined amount that can be lower than the value of your inventory, so read the cap carefully, ask what insurance the 3PL carries and consider insuring your own stock.
Can I leave a 3PL contract early?
Only on the terms the contract allows. Look for the notice period, any early-termination fees and the process for returning your inventory. Understanding exit terms before you sign avoids surprises later.
Can I review Evolution Fulfillment’s terms before I commit?
You should review any provider’s terms in writing before committing, and that includes ours. Contact us with your products, channels and volumes, and ask for the contract terms in writing as part of the quote conversation.
