3PL Notice Periods: How Much Notice to Give and How to Send It

Short answer: Most 3PL contracts require 30 to 90 days' written notice to end the agreement, and 90 days is common for larger operations. Your notice period sets the start of your whole switching timeline: count back from the contract end date, move the deadline to the previous business day if it lands on a weekend or holiday, and send notice exactly the way your contract's notices clause requires, with proof of delivery. Get your final inventory report, data export and fee list requested in the same letter. This is general information, not legal advice; check your own contract and, for anything contested, a lawyer.

How much notice do 3PL contracts usually require?

Industry guides put the typical termination notice period at 30 to 90 days. Warehouse marketplace Warematch describes it as "typically 30 to 90 days" and one of the more negotiable terms. Fulfillment consultancy F. Curtis Barry & Company calls 90 days common and, for large operations, recommends longer notice or a guaranteed wind-down period, because moving a big operation can take months.

Two other clauses decide how much room you really have:

• Termination for convenience vs. for cause. Leaving for convenience (no specific reason) usually triggers the full notice period and sometimes an early exit fee. Leaving for cause, such as repeated SLA failures, may follow a different process with a cure period.
• Auto-renewal. Many contracts renew automatically unless you send notice within a window before the term ends, often 30 to 90 days. Miss it and you may be committed to another term. Our guide to 3PL contract clauses covers term and renewal language in more detail.

How do you find your exact notice deadline?

1. Find the end date. Check the term clause and any renewal that already happened.
2. Find the notice period. Note whether it is counted in calendar days or business days.
3. Count back. End date minus notice period equals the last day notice can be received.
4. Check the calendar. If that date falls on a weekend or holiday, send it the business day before. The contract may not extend the deadline for you.
5. Check "received" vs. "sent." Many notices clauses count notice when it is received or deemed received, not when you mail it. Build in delivery time.

Worked example: your contract ends March 31, 2027 and requires 60 days' notice. Counting back 60 days lands on Saturday, January 30, 2027, so plan for your notice to arrive by Friday, January 29. With a 90-day notice period, the deadline is December 31, 2026, a holiday-season date when people are out of office, so send it well before. The 3PL Switching Timeline Planner does this math and moves weekend dates to the previous business day automatically.

How should you send notice to your 3PL?

Open the notices section of your contract (it is often near the end) and follow it exactly. It usually specifies:

• Method: commonly certified mail, a tracked courier or hand delivery. Email may or may not count; if the contract doesn't list it, don't rely on it alone.
• Recipient: a named person, title or legal department, and a specific address, which may differ from your account manager.
• Form: written notice, sometimes signed by an authorized officer of your company.

Good practice is to send by the required method, email a copy to your account contact the same day, and keep the tracking receipt and any written acknowledgment.

What should your notice letter include?

1. Your company's legal name and the contract name and date.
2. A clear statement that you are ending the agreement, the clause you are relying on and the effective end date.
3. A request for a final inventory report by SKU and lot, plus a full export of order, product and returns data.
4. A request for a list of removal, palletizing and outbound fees and the timing of final invoices.
5. Instructions on open returns and the date to stop accepting new orders.
6. A named contact on your side for the transition.

These are the same items the Timeline Planner recommends collecting before you give notice. Asking for them in writing at the start avoids surprises at the end.

What happens to your inventory after notice?

Your inventory stays yours, but a warehouse may hold it until charges are paid. Under the Uniform Commercial Code, a warehouse can have a lien on stored goods for storage and handling charges. F. Curtis Barry & Company notes that some vendors require invoices to be current before releasing inventory, and recommends separating undisputed amounts from disputes so inventory doesn't become leverage. Pay what is clearly owed, document disputes in writing, and agree the release schedule early. Our post on the real cost of switching 3PLs lists the fees to budget for.

How do you plan the switch around your notice period?

The notice period usually sets your overall timeline. Atomix's planner estimates four to eight weeks of hands-on work: one to three weeks for integrations, one to four weeks to move inventory and two to four weeks of overlap with both warehouses running. It also suggests avoiding moves between October 15 and January 10, when carriers and warehouses are at capacity. If your notice deadline falls in peak, give notice on time but schedule the physical move for January. For the full step-by-step process, see how to switch 3PL providers.

Frequently asked questions

Can I give notice by email?

Only if your contract's notices clause allows it. If it lists certified mail or courier, use that and send an email copy as a courtesy.

What if I miss my notice deadline?

You may be bound to the next notice window or a renewal term. Ask the 3PL in writing whether it will accept late notice or a shorter wind-down. Many will negotiate rather than keep an unhappy client.

Should I tell my 3PL before sending formal notice?

A short call is courteous, but the formal written notice is what counts. Make sure you have your data exports or your request for them in writing.

How much notice should I negotiate in a new contract?

Shorter notice gives you flexibility; longer notice gives the 3PL time to plan. Many brands look for 30 to 60 days without cause plus a clear exit clause covering data, inventory release and fees.
