Shipping delays are every retailer’s worst nightmare.

Whether it’s a package stuck in transit or the awkward job of explaining the delay to a customer, shipping mishaps can hold back your growth.

The problem is widespread. In Linnworks’ State of Commerce Ops 2026 report, more than a third of mid-market retailers said they struggle to manage delivery times, and around 40% cited shipping cost inflation as a top fulfillment challenge.

But it doesn’t have to be all doom and gloom. This guide explains what causes shipping delays, what they cost you, and nine practical steps to keep your shipments moving, including how Linnworks can help simplify your shipping operations.

What causes shipping delays?

Understanding what triggers delays helps you plan to avoid or reduce them. Here’s what’s typically rocking the boat.

Increased ecommerce demand

Online shopping volumes keep rising, and they spike around peak seasons and promotions. Those surges strain fulfillment centers and carrier networks, and when capacity runs short, delays follow. For how to prepare for peak demand, see our peak season ecommerce guide.

Port congestion and labor disruption

Major ports can become congested because of high trade volumes, labor disputes, or equipment and staffing shortages. When goods queue at the dock, everything downstream, including your restocks and customer orders, slows.

Carrier capacity shortages

When demand for shipping outstrips supply, available carrier capacity tightens. The result is a double hit: delayed shipments and higher transportation costs, including peak-season surcharges. For how those surcharges build up, see our report Lost in Transit: Why peak season shipping costs are so hard to track.

Customs and regulatory delays

International shipments are particularly vulnerable to delays caused by customs checks and duty regulations. Trade rules change often. The U.S. ended its de minimis exemption for low-value imports in 2025, for example, which added duties and paperwork to many small cross-border parcels. Check the current rules for every market you ship to.

Weather and natural disasters

Extreme weather and natural disasters disrupt shipping routes and logistics networks every year, and the increasing frequency of severe events keeps the risk to on-time delivery high.

The cost of shipping delays

When shipping grinds to a halt, the ripple effects can drain your business faster than you’d think.

Rising operational costs

Every day your goods are stuck in transit or at a port, the cost climbs. Think warehousing fees that add up, rerouting expenses when you’re forced to switch plans, and the premium you pay to expedite shipments that needed to be somewhere yesterday. It all eats into your margins.

Sales on the line

Nothing tests customer patience quite like a late delivery. Delays often lead to cancellations and lost sales, because customers may turn to competitors who can deliver on time. Every package stuck in shipping limbo is a missed chance to delight a customer and secure a sale.

Your reputation takes a hit

In the era of instant feedback and social media, a few shipping problems can trigger a wave of negative reviews. Persistent delays tarnish your brand’s image, shake customer trust, and can put off new customers. It’s a long road back once the damage is done.

9 ways to prevent shipping delays

Now that you know what causes delays and what they cost, here’s how to prevent them.

1. Communicate proactively with customers

When it comes to shipping, the first rule is clear communication. Keep customers informed about their orders. It’s not just transparency. It builds trust. Whether it’s a dispatch confirmation, a progress update, or an alert about a potential delay, every message shows you value their peace of mind.

Automate those updates so they’re timely and accurate. Linnworks sends tracking details back to each sales channel when an order ships, so customers can follow their parcel where they bought it, and you can pair that with automatic email or SMS notifications from your messaging tools. Good communication can turn a possible delay into a showcase of your customer service.

2. Choose the right service for each order

Choosing the wrong carrier or service level is a common, avoidable cause of late deliveries. The best option depends on the order’s destination, weight, and required speed, and picking it by hand for every order is slow and error-prone.

With Linnworks shipping management, you can set rules that choose the carrier and service for each order automatically, so orders go out by a method that meets the delivery promise at a sensible cost.

3. Offer free shipping

Free shipping has gone beyond a simple perk. It’s one of the strongest incentives for shoppers, and it can soften the sting of a wait by keeping the perceived value of your offer high. When shipping is free, customers tend to view extra transit time more forgivingly.

To make it work, manage shipping logistics carefully so free shipping stays cost-effective while still meeting delivery expectations. Setting a minimum order value, or building the cost into your pricing, are common ways to protect margin.

4. Keep on top of your inventory

Accurate inventory management is the backbone of efficient order fulfillment. When your records are precise, products are available when orders come in, which helps you avoid the backorder scenario that so often leads to shipment postponements.

Linnworks keeps stock counts accurate across your channels and warehouses, so you can see which items are running low and need replenishing. This proactive planning smooths fulfillment, prevents unexpected delays, and prepares you for peak seasons and promotions. Accurate data also shows which products to stock more of and which to phase out.

5. Use reliable shipping partners

Choosing a shipping partner isn’t only about who offers the fastest service. Reliability and trust matter just as much. Your carrier is an extension of your brand, and its performance can enhance or hurt your customers’ satisfaction. Performance history and reviews are your best clues to how well it will handle your parcels.

Negotiating service level agreements (SLAs) can be a game-changer. They should specify delivery times and include penalties for delays, which holds partners accountable and encourages them to prioritize your shipments. Working with carriers that consistently meet their promises reduces the risk of delays and protects your reputation.

6. Diversify your shipping options

Don’t put all your shipping eggs in one basket. Using multiple carriers, and alternative transportation modes such as air, sea, rail, and road where they fit, means there’s always a plan B. Whether it’s a port strike, unexpected weather, or a geopolitical issue, having multiple options keeps operations moving.

Linnworks lets you manage and connect multiple carriers from one platform, which makes it easier to switch carriers or adjust service levels quickly when conditions change.

7. Track shipments from dispatch to delivery

Tracking is your early warning system. Carrier tracking data lets you see where each parcel is, spot ones that have stalled, and contact customers before they contact you. It also gives customers the transparency they expect and cuts “where is my order?” inquiries.

Make tracking links easy to find in dispatch emails and on your order status pages, and check regularly for parcels with no recent scan. Catching a stalled shipment early gives you time to chase the carrier or send a replacement.

8. Strengthen supplier relationships

Strong supplier relationships are good business practice, and they’re also a strategic asset in minimizing supply chain disruption. Suppliers who value your partnership are more willing to go the extra mile when the unexpected hits.

Start by improving communication: regular meetings, shared performance metrics, and joint planning sessions help align objectives and expectations. That leads to better forecasting, smoother operations, and faster resolution of issues that could otherwise cause delays. If a supplier knows about a disruption in their region, they can warn you early, so you can pivot to alternative sources or adjust your inventory.

9. Increase supply chain resilience

Resilience is crucial for handling the unpredictable side of global commerce. Safety stock gives you a buffer to meet demand during unexpected supply disruptions. Regularly reviewing your suppliers and logistics strategy helps you adapt to market changes. See our guide to retail supply chain management for a step-by-step contingency plan.

Keep an eye on global events, and put contingency plans in place so you can react quickly. With accurate inventory and supplier data in Linnworks, you’re better prepared for whatever comes next.
