Roughly forty nine percent of abandoned carts in the US cite unexpected shipping cost as the reason, per Baymard Institute research. Most stores are leaving real revenue on the table because their shipping policy is buried, vague, or contradictory with what the checkout actually charges.
Your shipping policy is one of the highest leverage pages on the entire site. Done well, it prevents abandonments, prevents support tickets, and gives customers the confidence to click buy. Done poorly, it does the opposite.
What customers want to know in under ten seconds
Customers do not read shipping policies. They scan them, looking for four specific answers. If they do not find each one quickly, they bounce.
How long until you ship my order? How long until it arrives? How much does shipping cost? At what cart value does shipping become free?
Anything else is supplementary. Lead with those four. Detail comes after.
The shipping policy is the most-read page on the store after the product detail page. Treat it like a sales asset, not legal boilerplate.
The four decisions you have to make
Processing time
How many business days between order and ship. One to two days is the default expectation for in-stock items. Three to five if you are a small operation. Five to seven if everything is made to order. Be honest. Under promise and over deliver beats the reverse.
Shipping zones
Domestic only is fine to launch with and adds zero international complexity. International unlocks thirty to sixty percent more addressable market but adds customs work, returns logistics, and translation issues. A clean middle ground is domestic free shipping plus international flat rate.
Free shipping threshold
Set your threshold roughly thirty percent above your current average order value. If AOV is forty dollars, set free shipping at fifty. If AOV is seventy, set it at ninety. This pulls customers to add one more item without making the threshold feel out of reach. Brands that set free shipping at AOV waste margin. Brands that set it at twice AOV leave conversion on the table.
Delivery estimates per method
Standard is five to seven business days. Express is two to three. Overnight is one. List exact numbers, not "fast" or "soon." Stores that list specific ranges get fewer "where is my order" tickets because customers self serve from the policy.
The DDU versus DDP decision
The single most important call on an international shipping policy is how you handle duties and customs.
DDU (Delivery Duty Unpaid) means the customer pays duties at the door. Simpler to set up, but creates the worst customer service moments when the package arrives and someone owes the carrier an unexpected forty dollars.
DDP (Delivery Duty Paid) pre collects duties at checkout. Better customer experience, requires Shopify Markets or a duties calculator integration like Zonos.
For most stores under a million in GMV, DDU is the right starting point with one clear sentence in the policy. For premium brands or anyone whose international AOV exceeds eighty dollars, DDP pays for itself in customer experience.
What every working shipping policy includes
The four core decisions above, plus these specifics that prevent the most common support tickets.
An address edit window. Customers will type wrong addresses. The policy should tell them how to fix it. Usually a one hour window before fulfillment locks. Without that line, you absorb the cost of every re-route.
What happens to lost or stuck in transit packages. One line each. The policy does not have to solve every case, but it has to tell the customer how to reach you so the case starts moving.
Damaged on arrival policy. Photo within 48 hours plus replace or refund. Standard, but state it.
Holiday processing windows. Black Friday week. December. State explicitly that processing may extend by 1 to 2 business days during high volume periods.
What kills shipping policy conversion
Promising "fast" without a number. Fast means nothing. One to two business days means something.
Ignoring weekends and holidays. Business days, not calendar days. State it once at the top of the policy.
No tracking expectation. Customers expect a tracking link within twenty four hours of shipping. The policy should say so explicitly.
Treating international as an afterthought. One line on duties, one line on countries served, one line on extended timelines. Three sentences saves dozens of tickets a month at scale.
The shortcut
Writing a shipping policy from scratch is an hour long job the first time. If you have not done it before, our free shipping policy generator produces a clean policy in under a minute. Pick scope, processing time, delivery estimates, free shipping threshold, and duties model. The generator fills the template. Download as markdown, paste into Shopify, done.
The shipping policy pairs tightly with your return policy. Customers read both together when they are deciding to buy. Make them consistent in voice and explicit on the numbers. Or skip the entire assembly and have Zentrix build the full store from your idea, both policies included.
