Updated on July 27, 2026.
Peak season planning is here, bringing its trademark mix of anticipation and anxiety for ecommerce brands. While the holidays offer an incredible opportunity to expand reach and boost sales, the pressure is on as customer expectations for a positive experience are at an all-time high.
This year, brands face a complicated mix of stronger demand expectations and cautious consumer sentiment. The University of Michigan’s Index of Consumer Sentiment rose 10.5% from May to 49.5 in June 2026, but it remained 18.5% below June 2025. For the third consecutive month, more than half of consumers spontaneously mentioned that high prices were weighing on their personal finances.
Retailers are still preparing for growth. Kase’s 2026 Peak Season Retailer Sentiment survey found that 93% of retail and ecommerce fulfillment leaders expect demand to increase over 2025. However, 79% still anticipate being forced into reactive decisions once order volume spikes, even though 96% started peak season planning earlier this year.
Before brands start channeling their inner Grinch, there’s good news: plenty of ways still exist to stay agile, adaptable, and ready to maximize peak-season sales. Here are seven strategies to strengthen peak season planning before volume begins to rise.
When does peak season start?
When most people think of the holiday season, their minds jump straight to December, lights, cocoa, and holiday sweaters. But ecommerce insiders know the real action starts much earlier. Shopper activity may accelerate in late October, but operational peak season planning begins during the summer, when brands forecast demand, reserve carrier capacity, position inventory, confirm packaging requirements, and test fulfillment workflows.
The National Retail Federation (NRF) officially defines the holiday season as November 1 through December 31, but the main event happens with Black Friday and Cyber Monday (BFCM) weekend. That’s when inboxes overflow, carts fill up, and retailers battle for attention (and conversion).
Here are a few dates every retailer should keep on the 2026 calendar:
- November 26, 2026: Thanksgiving
- November 27, 2026: Black Friday
- November 28, 2026: Small Business Saturday
- November 30, 2026: Cyber Monday
- December 4–12, 2026: Hanukkah
- December 25, 2026: Christmas
- December 31, 2026: New Year’s Eve
Marketplace receiving windows, retailer routing deadlines, carrier schedules, and final ground-shipping dates will vary. Brands should confirm each deadline directly with the retailer, marketplace, carrier, or fulfillment partner rather than relying on dates used during a previous season.
Holiday 2025 showed that consumers still spent
If last season proved anything, it’s that cautious shoppers will still show up for the moments that matter. Holiday sales from November 1 through December 31, 2025, grew 4.1% over 2024, landing near the high end of the National Retail Federation’s forecast range.
Online shopping also reached a new milestone. Adobe reported that U.S. online holiday spending totaled $257.8 billion, up 6.8% year over year. Mobile devices accounted for a record 56.4% of online holiday sales, while traffic from generative AI sources to retail websites increased 693.4%.
Operationally, most retail teams also met the moment. Kase’s peak season survey found that 35% of organizations exceeded their 2025 expectations and 62% met them. That creates a strong baseline, but it also raises the bar. Strategies that worked at 2025 volumes may not hold if demand, costs, carrier constraints, or inventory complexity increase in 2026.
Current consumer sentiment suggests shoppers will remain selective. Year-ahead inflation expectations eased from 4.8% in May to 4.6% in June but remained well above the 3.4% reading recorded in February 2026. Brands should expect consumers to compare prices, wait for promotions, use flexible payment options, and prioritize products that deliver clear value.
But, before brands start feeling stress about the next peak season, take heart. Shoppers are spending, and there are plenty of ways to stay agile, adaptable, and ready to capture their attention all over again.
2026 peak season trends to watch
Effective peak season planning starts with understanding what may influence shopper decisions and operational performance. Consumer behavior continues to evolve, but brands that prepare for these shifts can protect margins while creating a more reliable customer experience.
Insight: AI and ChatGPT-powered shopping are becoming mainstream
The rise of conversational commerce is changing how consumers discover and buy products. Shoppers are now using AI assistants like ChatGPT to generate gift ideas, compare prices, and evaluate products before visiting a retailer’s website.
Adobe found that AI-driven traffic to retail sites increased 693.4% during the 2025 holiday season. That momentum continued into 2026, with AI-driven retail traffic rising 393% year over year during the first quarter.
Retailers that optimize their product feeds for AI search and provide clear, structured data will have a competitive advantage in visibility and conversion this year. Product descriptions should answer specific questions and consistently communicate pricing, availability, variants, delivery estimates, return policies, and product specifications.
Product data from Shopify merchants is now integrated into ChatGPT through Shopify Catalog, helping eligible products appear more accurately and completely in relevant shopping conversations. That makes product data quality an increasingly important part of peak season merchandising.
Insight: Early shopping will help consumers manage tighter budgets
With the cost of living still at the forefront of consumer concerns, many shoppers may spread holiday purchases over a longer period. Starting earlier allows them to compare prices, wait for discounts, use buy now, pay later options, redeem loyalty rewards, and avoid making every purchase within one short window.
Early promotions can help brands pull demand forward and reduce last-minute fulfillment pressure. However, they can also create uneven SKU demand, deplete individual components used in bundles, or shift inventory away from another sales channel. Promotions should therefore be planned alongside inventory allocation, replenishment, and fulfillment capacity.
The cost of those offers also requires closer attention. Kase’s survey found that 82% of retail leaders expect rising transportation and fuel costs to erode margins, while 80% said shipping costs significantly influence promotional strategy.
Insight: Reliable delivery promises will matter more than aggressive ones
As peak season nears its peak, patience runs thin. Brands that clearly communicate order cutoffs and offer reliable delivery windows will win those critical last-minute sales.
Kase’s survey found that 38% of retail leaders are already slowing or recalibrating delivery expectations. Customer satisfaction was also the top measure respondents planned to use when evaluating operational changes, cited by 61% of leaders.
Fast delivery can still be offered strategically for specific products, loyalty tiers, regions, or inventory positioned close to demand. But a realistic promise that arrives on time will generally protect customer trust better than an aggressive delivery estimate the operation cannot consistently meet.
Mastering peak season fulfillment: 7 tips for success
With an overview of what to expect, brands can utilize these tips for success:
1) Prepare to be agile
Even the best-laid plans hit snags once orders surge and networks tighten. The brands that thrive aren’t just the most prepared; they’re the most adaptable. Building contingency options, such as backup carriers, overflow fulfillment partners, or flexible inventory routing, ensures brands can pivot quickly when disruptions hit. During peak, the ability to reroute, reassign, and recover fast is what keeps promises and customers intact.
Although 90% of organizations surveyed by Kase said they have formal backup carrier plans, 81% remain concerned about carrier capacity and transportation disruptions. A plan on paper is not enough. Brands should test backup carrier connections, label generation, service mapping, pickup schedules, customer notifications, and rate-shopping rules before peak volume arrives.
2) Enable a cohesive, omnichannel experience
Flexibility is the name of the game. Mobile accounted for 56.4% of online holiday revenue in 2025, reinforcing the need for a buying experience that works consistently wherever a customer begins or completes an order.
Before creating a new channel or working on existing ones, be thoughtful in mapping out a seamless buying experience across brick-and-mortar locations, online channels, and buy online, pick up in-store options.
Whether customers grab a product off the shelf or with a quick tap on their phone, the experience should evoke the same brand personality and be packed with practical information.
Pricing, available inventory, product information, delivery estimates, loyalty benefits, and return rules should remain consistent as shoppers move among brand websites, marketplaces, social platforms, mobile devices, and physical stores. Fulfillment teams must also understand which inventory each channel can access and how orders should be routed when one location runs low.
3) Surprise and delight with a stellar unboxing experience
This is a special time of year for shoppers, especially if they are shipping gifts directly from an ecommerce store to their loved ones.
The package itself could be the ultimate present, so brands should take advantage of fulfillment marketing, like custom holiday branded packaging, marketing inserts, and discount codes to encourage repeat purchases.
If this is a first-time customer, it’s also a great opportunity to share a unique brand story, which builds identity and encourages customer loyalty.
Whether a retailer leans into creative copy or eye-catching graphics, make it a visual, engaging experience that social-media savvy shoppers feel compelled to grab their phone for.
In 2026, however, the unboxing experience also needs to account for packaging, labor, and shipping costs. Brands should finalize packaging components early, pre-kit inserts when possible, test packout times, and evaluate whether oversized boxes or decorative materials increase dimensional weight.
Pro-tip: look for a 3PL that values the customer experience over standard picking and packing.
“At Kase, we have customers that really value a certain type of unboxing experience, so we’re orienting products in a very specific way to curate that,” says John Servia, VP of Operations Excellence at Kase. “Others want branded documents, gift notes, packing slips, or other materials that reinforce their brand throughout the experience. It creates a little more fulfillment complexity on our end but ultimately helps our customers create the experience they’re looking for after the order is delivered.”
4) Prepare for shipping disruptions and stay transparent with customers
Peak season brings enormous shipping volume, and with it, plenty of potential for disruption. Weather events, carrier capacity constraints, labor shortages, and even traffic congestion around key distribution hubs can all create unexpected delays. Winter storms in particular can snarl routes, reroute freight, and extend delivery windows with little notice.
To stay ahead, leading retailers and 3PL partners should build contingency plans well before the rush. This includes diversifying carrier networks, maintaining buffer inventory across multiple fulfillment centers, and using data to monitor transit times and performance trends. Proactive communication with carriers and warehouse teams helps identify risks early and reroute shipments before they become bottlenecks.
Peak season planning should also account for demand surcharges, fuel adjustments, additional-handling fees, dimensional-weight exposure, residential delivery costs, and expedited shipping. Final carrier programs may not be available during early planning, so brands should model multiple cost scenarios instead of waiting for every fee to be announced.
Transparency is just as critical as preparation. During the holiday rush, customers are short on time and focused on delivery promises, which means even small surprises can impact brand trust. At checkout, clear communication about shipping cutoff dates, service-level expectations, and potential weather-related or carrier delays allows shoppers to plan with confidence.
Once an order is placed, integrated CRM and fulfillment systems can automatically send timely updates, including order confirmations, estimated ship dates, tracking details, and delivery notifications, keeping customers informed and reassured every step of the way.
The goal is not necessarily to promise the fastest delivery. It is to make a promise the fulfillment and carrier network can keep.
5) Avoid any ‘Goldilocks’ inventory effect
We’ve all felt the disappointment of finding the perfect present and then realizing the item is out of stock or on backorder.
While this situation is not always preventable, brands should do their best to order inventory appropriately. Ordering too much may mean a pricey bill and a packed warehouse, while too little sends customers to competitors.
But the right amount, just as Goldilocks learned, can help maximize sales.
Finding that balance is one of the biggest peak season planning challenges for 2026. Kase’s survey found that inventory imbalance is the top operational risk heading into peak, cited by 52% of retail logistics leaders. Although 85% are increasing inventory levels, 51% still identify stockouts as their leading customer experience risk.
To forecast demand, look back at historical sales data to get an accurate picture of sales, especially for seasonal items. Closely examine factors such as forecast versus order accuracy, inventory turnover, forecast accuracy, and order fill rate.
Forecasts should also be broken down by SKU, sales channel, promotion, region, and expected timing. Brands should build expected, high-demand, and lower-demand scenarios, then update those forecasts as promotional performance, inbound inventory, and consumer behavior change.
As the season approaches, stay tuned to inventory levels to see what may be running low. From there, communicate with suppliers to reorder or prepare a backup solution.
Inventory placement is as important as total inventory volume. Kase found that smarter inventory placement was the top margin-defense strategy, cited by 59% of retail leaders. Positioning high-velocity products closer to expected demand can reduce shipping zones, support faster delivery, and lower the risk that one region has excess stock while another experiences a stockout.
6) Refresh your returns process
Every retailer would love to see a zero-percent return rate for their products, but that isn’t a dream worth waiting for. In 2024, retail returns reached an estimated $890 billion, with online returns up significantly from the previous year.
Returns aren’t always seamless for consumers, which makes a clear and convenient process a key differentiator. Many brands are extending return windows during peak season and communicating policies upfront to reduce friction. Reverse logistics can be simplified through customer-friendly solutions such as the Loop X Kase partnership, while warehouse teams rely on defined SOPs to manage returns efficiently, from designating storage space to determining when to restock, refurbish, or dispose of products, particularly perishable items.
Returns planning should be completed before outbound volume peaks. Teams need clear rules for exchanges, refunds, return-to-stock timing, disposition, fraud review, seasonal labor, and inventory that arrives after a product’s strongest selling window has passed.
7) Conduct a peak season post-mortem and assess 3PL performance
Once the rush has settled, it’s the ideal time to evaluate how peak season really went and how well the logistics network performed under pressure. A thoughtful post-mortem helps identify what worked, what didn’t, and where improvements can strengthen resilience for next year.
Brands that partner with a third-party logistics provider (3PL) should take this opportunity to review service levels, communication, and scalability. A capable 3PL provides access to a broader carrier network, optimized transportation routes, and real-time visibility into inventory and fulfillment data. Many also offer value-added services (VAS) such as pre-kitting, product bundling, and retail compliance support — all of which can have a measurable impact on customer satisfaction and cost control.
The review should compare actual results with the original forecast, promotional calendar, labor plan, carrier strategy, and cost assumptions. Looking only at the final sales number can hide inventory imbalances, margin leakage, delayed orders, or customer experience problems.
To guide the review, key performance indicators (KPIs) can offer clarity on how well operations performed during the season:
Peak season KPI checklist
- On-time delivery rate: Measures carrier reliability and fulfillment efficiency.
- Order accuracy rate: Evaluates picking, packing, and labeling precision.
- Return rate: Indicates product quality, order accuracy, or fulfillment consistency.
- Average fulfillment time: Assesses processing speed from order to shipment.
- Inventory accuracy: Reflects how closely recorded stock matches physical inventory.
- Cost per order shipped: Highlights operational efficiency and cost management.
- Customer satisfaction or NPS: Captures the end-user experience post-purchase.
- Warehouse utilization: Gauges how effectively space and resources were used.
A clear-eyed review of these metrics enables teams to benchmark performance, strengthen 3PL partnerships, and set a stronger foundation for the next peak season.

FAQs about peak season planning
What is peak season preparedness?
Peak season preparedness is the process of ensuring inventory, labor, warehouse capacity, technology, carriers, packaging, customer communications, and returns workflows can support higher order volume. It includes testing the operation under multiple demand scenarios and creating contingency plans for disruptions. Preparedness should begin months before Black Friday rather than when orders have already started to rise.
How should brands plan for peak season delays in shipping?
Brands should diversify their carrier network, test backup services, review average transit times by region, and position high-demand inventory closer to customers. Checkout pages and order notifications should communicate realistic delivery estimates and explain when weather, capacity, or service disruptions affect an order. Brands should also define when orders can be upgraded, rerouted, or shifted to regional fulfillment nodes.
How should brands handle peak season surcharges?
Peak season surcharge planning should begin before carriers announce every final fee. Brands can model demand surcharges, fuel costs, dimensional weight, residential delivery fees, additional handling charges, and expedited services using expected, moderate, and high-cost scenarios. Packaging optimization, regional inventory placement, rate shopping, order consolidation, and free-shipping thresholds can help reduce exposure.
How can brands manage peak season demand planning?
Peak season demand planning should combine historical order data with promotional calendars, current sales trends, SKU velocity, channel forecasts, new product launches, and regional demand. Brands should create multiple scenarios and revisit them throughout the season. Forecasts should also be shared with fulfillment, procurement, marketing, customer service, carriers, and 3PL partners, so each team is planning around the same assumptions.
How can brands find retail shipping deadlines?
Retail shipping and delivery deadlines should be confirmed directly through the retailer, marketplace, or carrier website because dates can vary by service, seller program, destination, and inventory receiving method. Brands can also use Kase’s Peak Season Resource Center for current retail dates, carrier updates, surcharge information, planning guides, and shipping deadline resources.
