Every ecommerce merchant will deal with lost, damaged, and stolen packages. It's not a question of if, but how often and how well you respond. Americans lost an estimated $15.7 billion to package theft alone in 2024, with 241 million parcels disappearing from doorsteps, lobbies, and mailrooms. Add in damaged and lost-in-transit shipments, and the total cost to retailers runs well beyond that.
For merchants, every one of these incidents represents two problems at once: a direct financial hit and a customer relationship at risk. The good news is that most shipping failures follow predictable patterns, which means you can build systems that resolve the majority of them quickly and consistently. This article walks through how to handle each type of shipping failure, what to tell customers at each stage, and how to set up processes that keep these problems from consuming your support team.
Understanding the Three Types of Shipping Failures
Not all shipping problems are the same, and treating them as interchangeable leads to slower resolutions and frustrated customers. Each type of failure has different causes, different evidence requirements, and different resolution paths.
Lost Packages are shipments the carrier has no record of delivering. They may be stuck in transit, misrouted to the wrong facility, or simply unaccounted for. Lost packages are typically identified when tracking stops updating or the estimated delivery date passes without a delivery scan. Carriers have specific timelines before they'll officially classify a package as lost: USPS requires 7 days for Priority Mail and up to 30 days for Media Mail. FedEx waits 5 business days past the delivery date for most services. UPS requires that the delivery date has passed with at least 3 days without a tracking scan.
Damaged Packages arrive at the customer's door but the contents are broken, crushed, dented, or otherwise compromised. Damage can happen at any point in the shipping chain, from warehouse packing to carrier sorting to last-mile delivery - perhaps at the last moment of being thrown over a gate onto the porch. The cause matters because it determines who's responsible and what you can do to prevent it in the future.
Stolen Packages are confirmed as delivered by the carrier but never received by the customer. This is porch piracy, and it's the fastest-growing category of shipping failure. A recent survey found that 58% of Americans experienced package theft in 2024, up from 49% the year before. Unlike lost or damaged packages, stolen packages present a unique challenge because the carrier has technically fulfilled their obligation by completing the delivery.
The Financial Impact on Your Business
The direct costs of shipping failures are straightforward: you either reship the product, issue a refund, or both. But the indirect costs are where the real damage accumulates.
Direct costs include the replacement product, new shipping charges, refund processing fees, and the labor involved in handling the claim. For a typical mid-range ecommerce order, this adds up to $15 to $30 per incident excluding the direct cost of the replacement items.
Support costs compound on top of that. Each customer inquiry costs an estimated $4 to $6 to handle, and shipping problems rarely resolve in a single interaction. Between the initial complaint, the investigation, and the resolution, a single lost package can generate three or four tickets.
Customer churn is the most expensive consequence, and the hardest to measure. Research shows that 51% of consumers are unlikely to repurchase from a merchant after receiving a damaged order. The damage extends beyond the individual customer: 23% of shoppers who have a poor delivery experience say they will never order again, and 16% actively warn others to avoid the brand. When delivery failures are the leading cause of 1-star reviews, each unresolved incident has a long tail.
For a merchant processing 1,000 orders per month with a combined loss/damage/theft rate of 3%, that's 30 incidents per month. At a conservative average cost of $25 per incident in direct costs alone, that's $750 per month, or $9,000 per year, before accounting for churn and reputation damage. If the AOV for the store is $100, that brings the total direct financial costs above $40,000!
Setting Up a Process for Lost Packages
When a customer reports that their order hasn't arrived, the first step is determining whether the package is actually lost or simply delayed. Check the tracking information before taking any action. If tracking shows the package is still in transit and within the carrier's delivery window, the best response is to share the tracking status with the customer and set expectations for when to follow up.
If tracking has stalled or the delivery window has passed, it's time to act.
Step 1: Verify the shipping address. A surprising number of "lost" packages were shipped to an incorrect or outdated address. Confirm the address on file matches what the customer intended before assuming the carrier lost the shipment.
Step 2: File a tracer or claim with the carrier. Each carrier has its own process and timeline. USPS requires you to file within 60 days of the mailing date, with decisions typically coming in 5 to 10 business days. UPS allows 60 days from the shipment date. FedEx requires claims within 60 days for undelivered shipments. Keep in mind that carrier claims can take anywhere from one to several weeks to resolve, which is far too long to leave your customer waiting.
Step 3: Decide whether to reship or refund immediately. This is where many merchants get stuck. The instinct is to wait for the carrier investigation to conclude, but that puts the customer in limbo. A better approach is to set a dollar threshold: for orders below a certain value (many merchants use $50 to $75), reship or refund immediately without waiting for the carrier. For higher-value orders, communicate clearly with the customer about the investigation timeline and provide interim updates.
Step 4: Communicate proactively. Don't make the customer chase you for updates. Send an acknowledgment as soon as they report the issue, provide a timeline for resolution, and follow up at each stage. Even if there's no new information, a brief "we're still working on this" message shows the customer they haven't been forgotten.
Handling Damaged Shipments
Damaged packages require a slightly different approach because you need evidence to determine what happened and, in many cases, to file a carrier claim.
Collecting evidence from the customer. Ask the customer to provide photos of the damaged item, the packaging, and the shipping label. Make this as easy as possible. A simple email reply with phone photos is sufficient for most claims. Avoid requiring customers to fill out lengthy forms or provide excessive documentation, as the friction will push them toward a refund request or a negative review instead.
Determining the cause. Damaged shipments generally fall into three categories. Packaging failure means the product wasn't adequately protected for transit. This is your problem to fix, and it will keep happening until you improve your packaging. Carrier mishandling is when the package was dropped, crushed, or exposed to weather during transit. This is the carrier's responsibility, and you should file a claim. Product fragility means the item is inherently difficult to ship without damage. If certain products consistently arrive damaged, the solution may be upgraded packaging, different carrier services, or clear customer-facing warnings about shipping limitations.
Resolving the issue. Speed matters more than process here. For low-to-mid-value items, the fastest path to a satisfied customer is to reship immediately or issue a refund, then deal with the carrier claim on the back end. For higher-value items where you need the damaged product returned for inspection or a carrier claim, provide a prepaid return label and reship the replacement as soon as the return is in transit, rather than waiting for it to arrive.
Using damage data over time. Track which products get damaged most frequently, which carriers and routes have the highest damage rates, and which packaging configurations perform best. This data is one of the most actionable things your returns and claims process can produce. If a particular SKU has a 10% damage rate while the rest of your catalog sits at 2%, that's a packaging or product issue worth fixing.
Responding to Stolen Packages
Stolen packages are the most difficult category to handle because the carrier's job is technically done once the package is marked as delivered. That leaves the merchant in an uncomfortable position: the customer says they didn't receive it, the carrier says they delivered it, and someone has to absorb the cost.
What you can verify. Start with the carrier's delivery confirmation. Many carriers now provide photo proof of delivery, which can help determine whether the package was left in a visible or vulnerable location. GPS data on the delivery scan can confirm whether the driver was at the correct address. If the delivery photo shows the package at the wrong door or in an insecure location, you have grounds for a carrier claim.
What you can't control. Once a package is on a customer's doorstep, you have no ability to prevent theft. This is an important reality to acknowledge, both internally and with customers. Some merchants ask customers to file a police report before processing a replacement, but this adds friction and rarely leads to recovery of the stolen goods. For most order values, the cost of the police report requirement (in customer frustration and churn) outweighs the cost of simply replacing the order.
Setting a policy. Decide in advance how you'll handle theft claims and apply the policy consistently. Many merchants use a tiered approach: for first-time claims under a certain dollar threshold, reship without additional requirements. For repeat claims from the same customer or high-value orders, require additional verification such as a police report or a signed declaration. This balances customer experience with fraud protection.
The role of shipping protection. Stolen packages are one of the strongest use cases for shipping protection, because most carrier insurance policies do not cover theft after delivery. When a customer has opted into shipping protection at checkout, the protection provider handles the replacement claim, removing both the financial cost and the support burden from the merchant.
Proactive Prevention Strategies
The best approach to shipping failures is to prevent as many as possible before they happen. While you'll never eliminate them entirely, several strategies can meaningfully reduce the volume.
Shipping protection at checkout. Offering shipping protection shifts the financial risk of loss, theft, and damage to the protection provider. It also gives customers a clear, fast claims path that doesn't depend on carrier investigation timelines. (For a deeper look at how shipping protection works and what to look for in a provider, see our companion article on shipping protection.)
Signature confirmation for high-value orders. Requiring a signature on delivery is one of the most effective theft deterrents available. Studies show a signature requirement reduces theft by as much as 89%, and the reduction reaches 91% when combined with specific delivery instructions. The trade-off is convenience: customers need to be home to sign, which can lead to missed deliveries and redelivery attempts. For orders above a certain value threshold (many merchants use $100 to $200), the trade-off is worth it.
Proactive delivery notifications. When customers know exactly when their package will arrive, they can plan to be available or make arrangements. Real-time tracking updates, delivery day alerts, and "out for delivery" notifications all reduce the window during which a package sits unattended. 88% of online shoppers already use at least one strategy to monitor their packages in transit, so the infrastructure of customer attention is already there. Give them the information they need to act on it.
Discreet packaging. Branded packaging is great for the unboxing experience, but it also advertises what's inside. For high-value items or categories with high theft rates, consider offering a discreet packaging option that uses plain boxes without logos or product imagery. This is especially relevant during the holiday season, when porch piracy spikes.
Packaging upgrades for fragile items. If certain products consistently arrive damaged, the packaging is the first thing to revisit. Investing in better inner cushioning, double-walled boxes, or custom inserts for fragile items is almost always cheaper than the cost of replacements and lost customers over time.
Building an Internal Playbook
Handling shipping failures ad hoc is expensive and inconsistent. A written playbook ensures your support team resolves issues the same way every time, and it lets you set clear expectations with customers.
Decision trees by claim type. Create a simple flowchart for each type of shipping failure (lost, damaged, stolen) that guides your support team through the steps: verify the issue, collect necessary evidence, determine the resolution, and communicate with the customer. The flowchart should include specific dollar thresholds for automatic resolution vs. escalation.
Dollar thresholds for automatic resolution. Set a clear value below which your team can immediately reship or refund without waiting for carrier investigations or manager approval. Many merchants set this at $50 to $75. For orders above the threshold, define the escalation path and the expected resolution timeline. The goal is to resolve the vast majority of claims at the first level of support, quickly and without friction.
Carrier performance tracking. Not all carriers perform equally on all routes. Track damage rates, loss rates, and delivery accuracy by carrier and by region. If one carrier consistently underperforms on shipments to a particular area, that's actionable information you can use to adjust your shipping strategy. Some merchants find that switching carriers for specific zones reduces their incident rate significantly.
Fraud monitoring. A small percentage of shipping claims are fraudulent. Track claim frequency by customer, flag accounts with repeated claims (especially for theft), and watch for patterns like multiple claims from the same address or claims filed within hours of delivery. Build fraud thresholds into your playbook so your team knows when to apply additional verification without slowing down legitimate claims.
Regular review cadence. Set a monthly or quarterly review of your shipping failure data. Look at total claim volume, cost per claim, resolution time, and customer retention after claims. Identify trends, adjust your packaging or carrier strategy, and update your playbook based on what the data shows. The merchants who treat shipping failures as a data problem rather than a one-off customer service problem are the ones who see their incident rates decline over time.
Conclusion
Lost, damaged, and stolen packages are an unavoidable part of running an ecommerce business. The difference between merchants who lose customers over these incidents and merchants who strengthen relationships through them comes down to systems. A clear internal playbook, dollar thresholds for fast resolution, proactive communication at every stage, and prevention strategies like shipping protection and signature confirmation all work together to keep shipping failures from becoming customer failures. The goal isn't to eliminate every incident. It's to resolve them so quickly and smoothly that the customer's trust in your brand actually increases.
