Shipping

Shipping is the process of transporting a product from a seller, warehouse, or fulfillment center to a customer’s address, covering everything from carrier selection and rate calculation through to final delivery and tracking.

Shipping is widely cited as one of the largest operating costs in ecommerce, and its price depends on several interacting factors rather than a single fixed number. Carriers calculate cost based on package weight, dimensions, destination, and delivery speed, with most major carriers pricing destinations using shipping zones that group locations by geographical distance from the shipment’s origin.

A frequently overlooked factor is dimensional weight, calculated by multiplying a package’s length, width, and height and dividing by a carrier-specific factor; carriers charge whichever is higher, actual weight or dimensional weight, meaning a large but lightweight box can cost more to ship than its physical weight alone suggests.

How it works

From the moment an order is placed to the moment it reaches the customer, shipping generally follows a consistent sequence. Rate calculation: a price is determined, either through a flat rate, a single fixed price regardless of weight or destination within a set zone, or a carrier-calculated rate, which pulls live pricing from a carrier such as UPS, FedEx, or USPS based on exact weight, dimensions, and destination.

Carrier selection: the seller chooses which carrier and service level will handle the shipment, often using more than one depending on package size and cost, since no single carrier is cheapest for every shipment type.

Label generation and handoff: a shipping label is created and the package is handed to the carrier through drop-off or scheduled pickup. Transit and delivery: the carrier moves the package through its network to the final address, with tracking typically available to both seller and customer throughout.

Example

An online store selling both small jewelry items and larger home décor pieces is deciding on a shipping strategy. For the lightweight jewelry, the store owner finds that a flat $5 rate works well, since the items are cheap to ship regardless of destination. For the bulkier décor pieces, where shipping costs vary significantly by weight and distance, the owner switches to carrier-calculated rates at checkout, so customers see an accurate price reflecting the specific item’s size and their location, rather than a flat rate that might lose money on distant or oversized orders.

Key characteristics

• Flat rate vs. carrier-calculated: Flat rate offers customers one predictable price and simplifies checkout, while carrier-calculated rates reflect the exact cost for each specific order, better suited to stores with highly variable product sizes.
• Shipping zones affect cost: Carriers generally charge more for destinations farther from a shipment’s origin, grouping locations into zones that determine the base rate before other factors are added.
• Dimensional weight matters for large, light items: Carriers charge based on whichever is greater between a package’s actual weight and its dimensional weight, calculated from its size, which can significantly affect the cost of bulky but lightweight products.
• Surcharges add to the base rate: Fuel surcharges, residential delivery fees, and charges for oversized or fragile items are common additions on top of a carrier’s base shipping rate.
• Unexpected costs drive cart abandonment: Studies consistently identify unexpected shipping costs at checkout as one of the leading reasons online shoppers abandon their carts before completing a purchase.

Frequently asked questions

What is the difference between flat rate and carrier-calculated shipping?

Flat rate shipping charges customers one fixed price regardless of a package’s exact weight or destination within a set zone, simplifying checkout. Carrier-calculated shipping pulls live pricing from a carrier based on the order’s specific weight, dimensions, and destination, generally offering more accurate pricing for stores with varied product sizes.

What is dimensional weight and why does it matter?

Dimensional weight is a pricing method based on a package’s size, calculated by multiplying length, width, and height and dividing by a carrier-specific factor. Carriers charge whichever is higher between actual and dimensional weight, meaning large but lightweight packages can cost more to ship than their physical weight suggests.

Why do shipping costs vary by destination?

Most carriers group destinations into shipping zones based on geographical distance from the shipment’s origin, charging higher rates for farther zones. This is why shipping the same item to a nearby address typically costs less than shipping it across the country or internationally.

How does unexpected shipping cost affect online sales?

Unexpected shipping costs revealed late in checkout are consistently cited as one of the top reasons online shoppers abandon their carts. Many stores address this by showing shipping costs earlier in the buying journey, offering flat rates, or setting free shipping thresholds to reduce checkout surprises.
