What Does Your 3PL Need to Know Before Peak Season?

Before peak season, brands and their 3PLs should be aligned on expected order volume, upcoming promotions, inbound inventory, high-demand products, special fulfillment requirements, and important shipping deadlines.

Peak season can bring a lot of changes at once. More inventory may be arriving at the warehouse while order volume increases, promotions launch, carriers get busier, and customers expect their orders to arrive on time.

That's why some of the most valuable peak-season planning happens through conversations between a brand and its fulfillment partner.

Neither side can predict exactly what will happen during the busiest weeks of the year. But sharing what both teams know ahead of time makes it easier to prepare, adjust, and respond as demand changes.

Here are some of the conversations worth having with your 3PL before peak season begins.

1. Share What You Know About Expected Order Volume

Forecasts don't have to be perfect to be useful.

Looking at typical order volume, previous peak seasons, planned promotions, and recent growth can give both the brand and 3PL a starting point for discussing what the upcoming season could look like.

Helpful information might include:

Typical daily order volume
Expected peak order volume
Dates when larger spikes may occur
Previous peak-season volume
Significant growth or changes since last year

For example, if a brand typically ships 500 orders per day but could see significantly higher volume around Black Friday, that's helpful context for the fulfillment team.

The goal isn't to predict an exact number of orders months in advance. It's to establish a reasonable expectation and keep the conversation going as forecasts become clearer.

2. Talk Through Upcoming Promotions

Promotions can create some of the biggest order spikes of peak season, especially around Black Friday and Cyber Monday.

If you're planning a major sale, product launch, email campaign, influencer campaign, or other promotion, talking through those plans with your 3PL ahead of time can help both teams prepare.

Even if you don't know exactly how many orders a promotion will generate, sharing the timing, products involved, and expected impact gives your fulfillment team more information to plan around.

Your 3PL can also be part of that conversation. They may have questions about inventory availability, special packaging, shipping expectations, or other details that are easier to work through before the promotion begins.

The goal isn't to perfectly predict demand. It's to make sure both teams are working from the same information.

3. Coordinate Incoming Inventory

Peak-season planning isn't only about orders leaving the warehouse. There's often a lot of inventory arriving too.

Brands and their 3PLs should have a shared understanding of:

What inventory is expected
Approximately how much is arriving
Expected arrival dates
Which SKUs are included
Whether inventory is needed for a specific promotion or launch

This becomes particularly important when large inbound shipments are expected close to major sales events.

Your 3PL can communicate receiving expectations and timelines, while your team can provide updates if a shipment is delayed, quantities change, or arrival dates move.

That coordination helps both sides understand what inventory will be available and when.

4. Identify Products That May See Higher Demand

Not every SKU experiences the same increase in demand during peak season.

A brand may already know that certain products will be featured in holiday marketing, included in a promotion, or likely to become seasonal best sellers.

Sharing those expectations with your fulfillment partner gives them a better picture of how order volume could be distributed across your inventory.

This doesn't require knowing exactly how many units of every SKU will sell. Even identifying a handful of products expected to see higher demand can provide useful context.

Your team knows what's happening with marketing and merchandising. Your 3PL knows what's happening inside the fulfillment operation. Peak-season planning is stronger when those two perspectives come together.

5. Plan Special Projects Together

Holiday fulfillment can look different from the rest of the year.

Brands may introduce:

Holiday gift sets
Product bundles
Promotional inserts
Custom packaging
Subscription boxes
Gift messages
Special labeling

Projects like these can involve additional inventory, materials, labor, and fulfillment steps.

Talking through them with your 3PL ahead of time gives both teams an opportunity to work through the process before peak order volume arrives.

That might include determining what materials are needed, how products should be assembled, when the project needs to be completed, and whether anything about the normal fulfillment process will change.

Planning those details together can make the transition into peak season much smoother.

6. Align on Shipping Expectations and Deadlines

Peak season doesn't only affect warehouses. Parcel carriers and transportation networks are handling increased volume too.

Before the busiest part of the season, brands and their 3PLs should align on important shipping expectations, including:

Customer delivery promises
Carrier cutoff dates
Expedited shipping expectations
Retailer deadlines
Marketplace requirements
Time-sensitive promotions

This is another area where communication works both ways.

A brand can share the promises it's making to customers, while the 3PL can communicate carrier deadlines, operational cutoffs, or other information that may affect those expectations.

That helps keep marketing, customer service, and fulfillment on the same page.

7. Discuss What's Changing

Peak season may also coincide with changes elsewhere in the business.

Maybe you're introducing new products, adding a sales channel, working with a new retailer, changing packaging, or launching into a new marketplace.

Changes worth discussing with your 3PL could include:

New products or SKUs
New sales channels
Packaging changes
New retailers or marketplaces
Product launches
Changes to order flow
New fulfillment requirements

These conversations give both teams time to determine whether anything needs to happen differently within the fulfillment operation.

And if plans change along the way, that's okay. Keeping each other updated is more important than having every detail finalized from the beginning.

Peak-Season Communication Goes Both Ways

A strong peak-season plan isn't simply a brand handing its 3PL a forecast and walking away.

Your fulfillment partner should be communicating with you too.

That might include updates about:

Receiving timelines
Carrier cutoff dates
Operational changes
Information your 3PL needs from your team
Potential capacity considerations
Issues or delays that could affect orders

Both sides bring different information to the partnership.

The brand understands its promotions, customers, products, and growth plans. The 3PL understands what's happening inside the warehouse, with carriers, and across the fulfillment operation.

Bringing that information together makes it easier to adjust when something changes.

Frequently Asked Questions About 3PL Peak Season Planning

When should I start planning for peak season with my 3PL?

It's helpful to begin the conversation early enough for both teams to prepare for expected changes in inventory, promotions, and order volume. The right timeline depends on your operation, expected demand, inbound inventory, and any special projects. More complex peak-season plans may require earlier coordination.

What should my 3PL know before Black Friday and Cyber Monday?

Your 3PL should have a general understanding of expected order volume, promotion dates, incoming inventory, products likely to see higher demand, special packaging or kitting requirements, and important shipping expectations. These details can be updated as plans and forecasts change.

What if my peak-season forecast changes?

That's normal. Forecasts are estimates, and actual demand can change as peak season approaches. Share meaningful updates with your 3PL as new information becomes available so both teams can adjust their plans when necessary.

Better Peak Seasons Start With Better Communication

Nobody can predict every order, inventory delay, promotion result, or last-minute change that will happen during peak season.

That's not the goal.

Good peak-season planning is about making sure brands and their fulfillment partners have enough information to prepare together and can continue communicating as things change.

When both teams understand the expected volume, upcoming promotions, incoming inventory, special projects, and shipping expectations, they're better positioned to navigate the busiest part of the year together.
