The economic health of an e-commerce business depends on unit economics. A key metric in this field is the cost per order. This metric tracks the total cost to acquire and fulfill a single customer order.
Many businesses focus only on making more sales. However, sales volume does not always lead to more profit. If the cost to fulfill an order is too high, the business may lose money on every sale. Reducing cost per order is important for long-term survival.
In the quest to trim the fat, many brands are turning to white-label shipping solutions to maintain a premium brand image without the overhead of custom-built logistics. That can help slash operational costs. But there are many more ways you can reduce the cost per order. We’ll share them here:
#1 Boost Your Average Order Value
One of the most effective ways to lower the cost per order relative to revenue is to increase the amount spent in each transaction.
Many fulfillment costs, such as the labor to pick an order or the base shipping rate, remain relatively fixed regardless of whether a customer buys one item or three. Increasing the average order value (AOV) allows these costs to be spread across more revenue.
Free shipping is a powerful tool here. Data shows that about 45% of US adults expect free shipping on every order. However, 16% of those are willing to abandon their carts entirely if a shipping fee appears.
You don’t have to offer free shipping on every order, as it can destroy profits. Instead, you can set a free shipping threshold. This tells the customer they must spend a certain amount to get free shipping. This pushes them to add items until they cross the free shipping threshold.
Upselling and cross-selling are also effective. Upselling asks the customer to buy a better or bigger version of an item. Cross-selling suggests items that go well with what is in the cart. These methods work because the customer is already in the mood to purchase.
#2 Outsource Fulfillment
For many e-commerce enterprises, the logistics of storing and shipping products eventually outpace their internal capabilities.
Outsourcing these operations to a third-party logistics (3PL) provider allows you to convert fixed costs into variable costs. You can also leverage the economies of scale that only large-scale fulfillment centers can provide. No wonder the 3PL market is expected to generate $4.3 trillion in 2035.
Retail-rate shipping is a primary driver of high CPO for small businesses. To counter this, 3PL providers aggregate shipping volume across hundreds or thousands of merchants to negotiate deep carrier discounts. That alone can slash standard shipping costs significantly and improve profit margins almost immediately.
If you want to maintain brand integrity, choose 3PLs that offer white-label order fulfillment. ShipOffers explains that, unlike traditional fulfillment, where third-party logos often clutter the packaging, white-label fulfillment keeps all branding strictly consistent with the e-commerce company. That ensures a seamless brand experience.
#3 Reduce Returns Through Better Product Education
Returns are one of the biggest silent killers of e-commerce profits. In 2024, returns cost retailers about $890 billion in the U.S. alone. When an item is returned, businesses lose the shipping cost, the labor to inspect it, and the product’s value if it cannot be sold again as new.
Most returns happen because the product fails to live up to customers’ expectations. Clothes, for instance, are mostly returned because they are the wrong size. Another common issue is bracketing, where a customer buys multiple sizes of the same shirt with the plan to return two of them.
A good product description does more than just sell. It informs the buyer. Descriptions should include exact dimensions, materials, and colors. This prevents surprises when the package arrives. If a customer knows exactly how a shirt fits, they are less likely to return it for being the wrong size.
Good visuals are the best way to stop a return before it happens. Upload high-resolution photos of your products from multiple angles. Offer Zoom features, so customers can see the texture and quality of the fabric.
Reducing the cost per order is not about doing one big thing, but about doing multiple small things correctly.
It takes a bit of detective work to look through your shipping invoices and ad reports, but the clarity you gain is worth its weight in gold.
Remember, you don’t have to change everything overnight. Pick one area and optimize that first. Once you see those few dollars coming back into your pocket, you’ll have the momentum to tackle the rest.
Over time, your business becomes more resilient. You won’t be as stressed when ad prices fluctuate, or a competitor enters the market, because your business will be running more efficiently than theirs.
