It may not be as glamorous as a perfectly executed marketing campaign, but small parcel shipping is still the engine behind nearly every ecommerce order.
According to a recent report, in 2025, the U.S. domestic parcel market generated $196 billion in revenue on 23.9 billion parcels, averaging 91 million parcels per weekday and roughly 1.84 parcels per adult each week. With volume projected to grow at a 3.9% CAGR to 26.8 billion parcels by 2028, small parcel strategy is only becoming more central to ecommerce growth, cost control, and customer experience.
That growth alone reflects how essential ecommerce small parcel shipping has become. Yet it’s often treated like background noise; something set up once and forgotten until a problem arises.
That approach is risky.
Shipping rates are climbing. Customer expectations are shifting. To top it off, global disruptions continue to ripple through supply chains. Brands that treat their small parcel strategy as an afterthought are likely to fall behind on both customer experience and cost efficiency.
The pressure is only getting more complicated in 2026. FedEx and UPS both announced 5.9% average general rate increases, while USPS announced a temporary 8% transportation-related price increase for select domestic shipping services from April 26, 2026, through January 17, 2027.
At the same time, the carrier landscape is shifting. For example, USPS and DHL ecommerce announced a more than $10 billion multi-year agreement in May 2026, with DHL handling pickups and sorting and USPS managing last-mile delivery across the U.S. That kind of move matters because it signals more competition, more carrier combinations, and greater complexity for brands evaluating small-parcel options.
The reality is: small parcel is not a set-it-and-forget-it strategy.
For ecommerce businesses, small-parcel shipping is one of the most important and most expensive parts of fulfillment. It represents a significant portion of logistics costs and directly shapes how customers perceive the post-purchase experience.
Sean Kim, VP of Parcel & Ecommerce at Kase, explained in a recent parcel conversation, “for most companies, shipping is either the first, second, or third largest expense in the company.”
Have you ever thought twice about ordering a product due to high shipping costs or slow delivery times? High shipping costs, unclear delivery times, or unreliable tracking are all small-parcel issues that can directly erode trust at the doorstep.
To stay competitive, brands need to get smarter about their small parcel strategy. When it’s not continuously optimized, there’s an increased risk of delivery delays, lost visibility, and growing costs. But, more importantly, losing consumer trust.
What is small parcel shipping?
Small parcel shipping refers to lightweight packages that can be lifted without any special equipment. These shipments are usually packed in branded or carrier-provided boxes and handled by national or local courier services. Key characteristics include:
- Packages typically fall between 1-15 pounds.
- USPS defines small parcels as weighing less than 70 pounds and fitting into 30x30x30 boxes.
- Delivered via vans or trucks under 28 feet long.
- Vehicles typically carry 50–100 parcels.
- Carriers make multiple stops throughout the day for door-to-door deliveries.
When well-managed, this model works incredibly well for ecommerce.
But for growing brands, “well-managed” is doing a lot of work. The right small parcel strategy must account for carrier mix, delivery promises, packaging decisions, surcharges, DIM weight, customer communication, and the cost of resolving issues that arise after a package leaves the fulfillment center.
Why small parcel shipping companies are changing the conversation
Streamlined small parcel shipping requires regular recalibration. Fluctuations in fuel costs, emerging regional delivery services, and growing customer focus on eco-friendly options can all impact shipping strategies. Smart retailers adapt their approach accordingly.
That is why more brands are rethinking how they work with small parcel shipping companies. It is no longer enough to ask who has the lowest published rate. Brands need to understand which carrier, service level, and fulfillment model supports the customer experience they are trying to create.
Fuel is a major example. Parcel Industry reported that the 2026 general rate increases from FedEx and UPS were more aligned with the headline 5.9% increase than in some previous years, but noted the reality is still more nuanced because accessorials, fuel, zones, and package profiles can all change the actual impact.
Fuel-related costs have also become harder to ignore. The Wall Street Journal reported that FedEx and UPS fuel surcharges averaged 19.4% of shipping charges in 2025, up from 6.3% in 2020, and reached as high as 26% in early March 2026, according to ShipMatrix data cited in the report.
But streamlined small parcel shipping is no easy feat. At scale, it introduces plenty of operational and financial pressures. Brands often face:
- Lack of visibility after handoff to the carrier.
- Inefficient packaging leading to inflated DIM weight and costs.
- High expectations for free or fast shipping, without margin to support it.
- Delivery variability that’s often out of the brand’s control.
None of these challenges are new, but they carry more weight today. Customers expect reliability and speed, while brands are under increasing pressure to improve efficiency.
Getting smarter with small parcel? That’s a key differentiator.
A smarter approach to small parcel
1. Focus on customer experience, not just transit time
No two companies are the same, and every brand has its own experience. Small parcel plays a large role in it, yet too often it defaults to shipping speed. The thing is, speedy delivery doesn’t always equal good customer experience. What matters more is consistency, clarity, and brand alignment.
Not every brand needs to offer same-day or even two-day delivery. What matters is that shipping options are transparent, on-brand, and operationally sustainable.
“The customer experience isn’t static. It shifts with economic conditions, consumer behavior, and global trade dynamics,” said Kim. “Brands that are able to navigate these shifts thoughtfully are more likely to adapt without sacrificing what matters most to their customers.”
Kim made the point even more directly: “parcel needs to be considered part of the brand experience, the customer experience.”
In practice, this might mean introducing slower, more affordable shipping options. Or revisiting a free shipping threshold to better align with changing customer expectations. The goal should be to offer delivery experiences that make sense for your customers and your business.
This is especially important as customers become more familiar with carrier names and service levels. They may not need every package in two days, but they do need trust. If a delivery promise is unclear, inaccurate, or tied to an unfamiliar carrier with inconsistent tracking, the customer may remember that more than the product itself.
2. Build flexibility across small parcel shipping companies
Consumers don’t limit their spending to one brand. And businesses shouldn’t limit themselves to one parcel carrier.
While sticking with a single carrier might feel simpler, it restricts flexibility. Being locked into a sole provider exposes brands to service outages, pricing changes, and missed opportunities to optimize for cost or speed.
Carrier-agnostic shipping, on the other hand, expands the playing field. With a network of regional and national carriers, brands can:
- Mitigate risk by routing around service disruptions.
- Take advantage of zone skipping or regional hubs.
- Match service levels to customer expectations without overspending.
A flexible carrier strategy enables smarter routing and more cost-effective decisions, especially as a retailer’s network scales or their customer base shifts geographically.
This is where the relationship between brands and small parcel shipping companies is becoming more strategic. The lowest-cost option is not always the lowest-risk option, and a cheap delivery can become expensive if it creates more customer service tickets, reships, refund requests, or negative reviews.
Low-cost carriers and customer experience may also be a tradeoff. Kim explained, “A company may have paid $5 for that delivery, but they lost that customer.”
That does not mean brands should avoid lower-cost services. Instead, they need to understand when those services are appropriate, where they perform well, and how they affect the customer promise. A carrier that works well for low-value, lightweight goods may not be the right fit for premium products, subscription boxes, or orders with high acquisition costs.
3. Don’t set it and forget it
Customer expectations, shipping costs, consumer behaviors…none of it stands still. Small parcel strategy should evolve alongside both a brand’s business and the market.
Amazon’s shift from two-day to three-day Prime is just one example of changing expectations. Free shipping is no longer a guarantee, and in some cases, charging for delivery may actually improve perceived value or sustainability.
When retailers stick with the same carriers, service levels, and thresholds year after year, they miss an opportunity to adapt proactively and stay competitive in a crowded industry. The key is to keep revisiting your strategy. Regularly reviewing shipping data, customer feedback, and carrier performance can uncover areas to improve cost, reliability, or experience.
That review should also include packaging and dimensional weight. USPS is aligning more closely with FedEx and UPS dimensional practices by rounding fractional package dimensions up to the next inch and changing the dimensional divisor for larger packages, according to recent reporting. For brands shipping lightweight but bulky products, even small packaging decisions can create a larger cost impact.
Brands should also pay attention to how carrier partnerships evolve. The USPS-DHL deal shows that last-mile delivery, regional access, and national coverage are evolving. That creates opportunities, but only for brands (or their partners) that are watching the market closely enough to adjust.
The key to optimized small parcel solutions? A customer-centric 3PL
Kase’s approach to small parcel shipping focuses on the customer experience first and foremost. We see small parcel as an extension of the brand, not just a cost center.
We start by understanding the customer experience our partners want to create, then designing a small parcel solution that aligns with operational goals and budget.
That means evaluating carriers, optimizing packaging, and using data to improve over time. During periods of economic uncertainty or change in global trade, we work closely with our customers to adapt and adjust—without compromising the end experience.
Every brand defines customer experience differently. Kase’s role is to help translate that vision into a parcel strategy that works, not just for their customers, but for their budget.
The best small parcel strategy builds a flexible shipping program that protects margin and supports customer trust. The right 3PL should help brands compare small parcel shipping companies, understand the true cost of each service, and make better decisions before parcel costs turn into customer experience problems.
