Peak season puts shipping under the most pressure of the year. Order volumes surge, carriers add surcharges, delivery windows tighten, and one slip can mean late parcels, unhappy customers, and margin that disappears into costs you didn’t plan for.

The good news is that most of it is predictable. This guide covers how to prepare for peak shipping, understand where costs hide, choose and negotiate with carriers, run your warehouse, set realistic delivery promises, and review what happened afterward. For the wider season, see our peak season ecommerce guide.

How to prepare for peak season

Start with demand. Forecast what you expect to ship, using last peak’s data, current trends, and your promotions calendar. Your past peak season data holds most of what you need. Ask which products sold fastest, where the bottlenecks were, and which products didn’t sell. See our guides to inventory forecasting and peak season inventory planning.

Then talk to suppliers and carriers earlier than you think you need to. Share your forecasts and inventory plans, build the relationships, and set clear expectations so everyone is working to the same plan. Here’s a quick checklist:

• Forecast demand. Use your sales history and trends to estimate order volume by week.
• Plan inventory. Get stock in early, and in the right locations.
• Analyze past data. Find patterns in what sold and where fulfillment struggled.
• Coordinate with suppliers and carriers. Agree expectations and cut-off dates before the rush.

Understand peak surcharges before they reach your invoice

A peak surcharge is an extra fee carriers add during the busiest weeks of the year, on top of fuel, size, and weight charges. Most sellers know they exist. What catches people out is how they stack up and where they hide. In Linnworks’ analysis of nearly 70 million peak-season shipments in the US and UK, a few patterns stood out:

• The rate card isn’t the real price. Peak surcharges sit on top of other charges, and negotiated discounts often don’t cover all of them. A good contract doesn’t guarantee no peak exposure, so ask your account manager what your discount actually applies to.
• Small details trigger costs. In Shippo’s peak-season data, 4.3% of shipments triggered a post-purchase surcharge that the merchant hadn’t seen at checkout, and costs tend to go missing in small shipments, not just the big, obvious ones.
• Carrier windows start early. Peak programs begin in the autumn, and several structural surcharges have already risen. Revisit contracts now, not in November.

The sellers who come out ahead aren’t the ones who find a cheaper carrier after the invoices arrive. They’re the ones who know where their costs go missing and who’ve automated the decision for every order before the season starts.

Ways to optimize your shipping strategy

A reliable peak shipping strategy takes planning. In the State of Commerce Ops 2026 report, around 40% of mid-market retailers cited shipping cost inflation as a top fulfillment challenge, and high-performing retailers were more likely to diversify their carriers. These are the key steps:

• Evaluate carriers. Assess reliability, coverage, and customer service. Not all carriers are equal, and the right ones help you deliver on time.
• Compare rates and times. Look for carriers that offer the best rates for the delivery speeds you need, and balance cost with efficiency. Cheaper isn’t better if it compromises delivery times or service.
• Use more than one carrier. Relying on a single carrier is risky. A multi-carrier approach lets you choose the best option for each shipment based on destination, cost, and delivery time.
• Make carrier choice a per-order decision. Instead of setting one default, route each order to the carrier that suits that specific package. Linnworks’ rules engine can do this automatically, and its shipping management connects to 70+ carriers.

A well-optimized shipping strategy improves your bottom line as well as customer satisfaction. For more, see our guides to getting better shipping rates and common shipping problems.

Set delivery promises and cut-off dates you can keep

Fast delivery wins sales at peak, but a promise you can’t keep costs more than a slower promise you can. To protect both:

• Set clear order cut-off dates for each delivery speed, and show them on product pages, at checkout, and in your emails.
• Build in a buffer. Carriers slow down at peak, so don’t promise the fastest possible timeline.
• Offer expedited options where the economics work. Many shoppers will pay more for faster delivery, but only offer what you can deliver.
• Tell customers early about any delays, and send status updates at key stages.

How to enhance your warehouse operations

Warehouse performance isn’t something you can fix once and forget. It needs a plan and regular tuning. Start with these three things:

• A layout that cuts travel time. Organize your warehouse to minimize walking and make the most of your space, with safe aisles and clear paths. Place best sellers where they’re easiest to pick.
• Training for peak. Train existing and temporary staff on safety, equipment handling, and efficient picking, packing, and shipping.
• Systems that track stock and tasks. Inventory and warehouse software tracks stock levels, manages reordering, and guides picking, which reduces errors and frees your team for higher-value work.

See our guides to efficient order picking, warehouse KPIs for peak season, and when you need a warehouse management system. For staffing, see seasonal hire vs. overtime.

Outsourcing holiday fulfillment

If your warehouse can’t handle peak volumes, or you want stock closer to customers, a third-party logistics (3PL) provider can add capacity. Outsourcing can make sense for overflow, for new regions, or for the whole season. In the State of Commerce Ops 2026 report, high-performing retailers were more likely to use 3PL partners to extend their fulfillment reach. Before you commit, ask any provider about:

• Capacity and cut-off dates during peak, and any peak fees
• How inventory and order data will flow between your systems and theirs
• Service levels, accuracy, and how they handle returns
• Onboarding time, which can be longer than expected

See our guide to 3PL warehouse logistics.

The importance of effective packaging solutions

Packaging is your first line of defense against damage and extra cost. Choose materials that fit your products snugly and are durable, such as corrugated boxes, protective inserts, and eco-friendly alternatives that match your brand. A well-packed item arrives intact and reduces returns.

Packaging also affects cost. Carriers charge by size as well as weight, and oversize and additional handling thresholds can add charges, so right-sizing your packages helps. Accurate labels are the final touch: clear, durable labels with the shipping address, return address, and any handling instructions keep parcels moving. See our guide to ecommerce packaging.

A quick checklist of packaging materials, which often get overlooked:

• Custom-fit inserts: prevent movement and protect items
• Void fill: fills space so products don’t shift
• Shrink wrap: keeps items secure and protected from moisture
• Desiccants: prevent moisture damage in transit
• Fragile labels: alert handlers to take extra care
• Reinforced tape: keeps heavy packages closed

The role of tracking and communication

Even with good packaging and an efficient warehouse, things go wrong: stock falls short after an order is placed, or a carrier hits a road closure. When they do, tracking and communication reassure customers and let you act on a solution.

Set clear delivery timelines and send automated notifications at key stages: order confirmation, dispatch, and expected delivery. Shoppers at peak are impatient, so proactive updates reduce support contacts and protect your reputation.

Ways to manage returns during peak season

More orders mean more returns. You’ll need to fulfill new orders while accepting returns and restocking, and the surge usually lands after the holidays. To prepare:

• Set a clear return policy. Consider an extended gift return window, and make the terms easy to find.
• Plan capacity. Assign staff and space to receive, inspect, and restock returns.
• Make returns easy. A returns portal or prepaid label process reduces contacts and speeds things up.
• Restock quickly. Returned items that are back in available stock can still be sold during the season.

See our guide to returns management.

How to use technology and automation

You can’t prevent every peak-season complication, but you can set up systems that handle the repetitive work. Linnworks’ research points to three places to apply automation: when you allocate inventory, when you choose a carrier, and before you print a label. A packaging or dimension check before label printing, for example, can catch an order drifting toward an oversize or additional handling charge while there’s still time to repack. Start by documenting:

• Reorder points for inventory items: to automate replenishment and prevent stockouts
• Supplier lead times: to time restocking and manage inventory levels
• Order fulfillment workflow steps: to find tasks that can be automated
• Carrier performance: to choose carriers on speed, cost, and reliability
• Customer order patterns: to predict demand and set inventory levels

For example, if your analysis shows supplier lead times often delay restocking, automated reorder points that account for those lead times keep inventory at the right level during peak. To calculate a reorder point, you need two things: lead time demand (the inventory you sell between ordering and receiving stock) and safety stock (extra inventory to cover unexpected demand or delays).

Reorder point = (average daily usage × lead time) + safety stock

If you sell 10 units a day, your lead time is 7 days, and you keep 20 units as safety stock, your reorder point is (10 × 7) + 20 = 90 units. When stock reaches 90 units, place a new order. See our guide to the safety stock formula.

For more on automating peak workflows, see our guides to rules engine workflows and what to automate first.

Ways to collaborate with shipping partners

Strong carrier relationships are a core part of a peak shipping strategy. Keep in regular contact, not just when something goes wrong, and plan together. Collaborate on contingency plans so you know what happens if a carrier hits capacity limits.

Negotiate early. You’re offering volume, and carriers often reward higher volume or longer commitments with discounted rates. Ask which fees your discount covers, including peak surcharges and accessorial charges, and what the cut-off dates are for peak programs. A platform that connects your carriers to your orders and inventory makes it easier to compare rates and switch volume when you need to. See our guide to getting better shipping rates.

Why post-peak analysis matters

When peak is over, review what happened and what to change. Take stock of five areas:

1. Order fulfillment rates. How quickly and accurately were orders processed and shipped? Find bottlenecks and plan to fix them.
2. Customer feedback. Look for patterns in complaints and praise. If many customers mention damaged packaging, you may need better materials or carriers.
3. Inventory management. Check for stockouts and overstock, and adjust planning and reorder points.
4. Carrier performance. Review delivery times, costs, and reliability, and decide whether to renegotiate or change carriers.
5. Financial impact. Look at margins, shipping costs, and unexpected expenses, including surcharges, and use them to refine next year’s budget.
