What Young Shoppers Really Want from Online Stores — A Guide for Retailers
5 December 2025
How Digital Transactions Transform Supply Chain Operations
5 December 2025If you’re selling to customers in the EU, you’ve probably already realised one thing: shipping to Europe doesn’t feel like shipping at home. Deliveries travel farther, they pass through customs and they usually change hands between several carriers before they reach the customer. And because European shoppers have pretty high expectations around delivery speed and tracking, even small issues can quickly turn into negative reviews or lost sales.
That’s why having the right logistics KPIs isn’t just “nice to have.” It’s the only reliable way to see what’s actually happening inside your delivery pipeline – which carriers are performing well, where delays come from and how consistent your customer experience really is across different EU countries.
The good part? You don’t need a long spreadsheet to make sense of it all. A focused set of KPIs can give you a clear picture of your performance and help you make smarter decisions as you scale into Europe.
In this article, we’ll walk through the key KPIs worth tracking when you ship cross-border to the EU. For each one, you’ll see what it measures, why it matters for non-EU sellers and how you can calculate and improve it. By the end, you’ll know exactly which metrics will help you deliver faster, reduce surprises and build trust with European customers.


OUR GOAL
To provide an A-to-Z e-commerce logistics solution that would complete Amazon fulfillment network in the European Union.
1. On-Time Delivery Rate (OTD)
What it measures
OTD is simply the share of orders that arrive when you said they would. So for example, if you promise 5–7 days and the parcel shows up in that window, it counts as “on time.”
Why it matters for the EU market
European customers take delivery promises seriously. If something is late, they notice — and they don’t hesitate to leave a review saying so. For non-EU sellers, this KPI becomes even more important because there are more points where delays can sneak in: customs, long flights, slower handovers between carriers or even local courier bottlenecks. A consistently high OTD tells you your cross-border setup is working the way it should.
How to calculate it
On-Time Delivery Rate = (Orders delivered on or before the promised date / Total delivered orders) × 100
Quick example:
Let’s say you shipped 500 orders last month.
455 were delivered within the promised delivery window.
45 arrived late.
Your OTD would be:
(455 / 500) × 100 = 91%
This is generally considered a healthy result for cross-border EU shipping.
Typical benchmarks
These shift by country, but as a general reference:
Around 90–97 percent is considered solid for EU B2C deliveries.
Western Europe tends to run faster and more reliably than the south or east.
Peak season can easily push your OTD down a few percentage points.
How to improve it
Look at OTD by specific destination country instead of one global average, as it can reveal potential issues much faster.
Choose carriers that handle customs efficiently or offer pre-clearance.
Don’t rely on one delivery partner — mix carriers to reduce risk.
If transit times swing a lot, consider storing your top sellers inside the EU.

2. Average Delivery Time (Transit Time)
What it measures
Average delivery time shows how long it actually takes for a package to reach the customer — from the moment the order is handed over to your carrier until it’s delivered.
Why it matters for the EU market
Many customers are used to 2–4 day domestic delivery, so even cross-border shipments are expected to be reasonably quick and predictable. When your average delivery time is longer than expected (or swings up and down week to week), you’ll see it show up in reviews, customer inquiries and conversion rates.
For non-EU sellers, this KPI is especially important because two major variables can slow things down:
Customs clearance: even small documentation mistakes can add days.
Local carrier differences: Germany, France, Spain and Italy all deliver at different speeds.
Tracking this KPI helps you understand not only “how fast” you are, but “how consistent” you are.
How to calculate it
Average Delivery Time = Sum of all delivery durations / Number of delivered orders
Quick example:
Imagine you delivered 5 orders and their delivery times were:
6 days, 7 days, 5 days, 8 days and 6 days.
Total = 32 days
Divide by 5 orders → 32 ÷ 5 = 6.4 days
Your average delivery time is 6.4 days.
Typical benchmarks
These vary a lot, but as a rough guide:
5–8 days is common for cross-border shipments to major EU markets.
Deliveries inside the EU (if you use fulfilment in Europe) often land in the 1–3 day range.
Southern Europe (e.g., Spain, Italy, Greece) usually adds 1–2 extra days compared to Germany or the Netherlands.
How to improve it
Double-check your customs documentation — even one missing detail slows everything down.
Test multiple carriers to see which ones perform best on specific lanes.
Use pickup/drop-off points in countries with lower home-delivery success rates.
For high-volume SKUs, think about storing inventory in the EU, as it removes the entire customs step.
Monitor not just the average, but also the spread — if some orders take 4 days and others 12, predictability becomes an issue.
3. First Attempt Delivery Success Rate
What it measures
This KPI shows how often the courier manages to deliver a package on the first try. If the customer isn’t home, the address is unclear or the carrier can’t access the building, the first attempt fails — and that failure usually adds 1–3 extra days to the final delivery time.
Why it matters for the EU market
Europe is a patchwork of different delivery habits. In some countries, people expect parcels to be left with a neighbour. In others, carriers rely heavily on pickup points. Apartment buildings often require access codes. Doorbells don’t always match the name on the label. All of this makes first-attempt success more complicated than it seems.
When the first attempt fails:
your delivery time goes up,
your OTD drops,
and your WISMO tickets usually spike.
For sellers shipping from outside the EU, this KPI helps you understand whether delays come from the carrier, the last-mile environment, or simply from poor address quality.
How to calculate it
First Attempt Delivery Success Rate = (Successful first attempts / Total delivery attempts) × 100
Quick example:
You shipped 300 orders.
In 240 cases, the courier delivered on the first try.
In 60 cases, they had to try again or redirect to a pickup point.
Your rate is:
(240 / 300) × 100 = 80%
In the EU, 80 percent is decent, but there’s room for improvement.
Typical benchmarks
Benchmarks differ widely between countries:
85–95% is considered strong for most urban areas in Western Europe.
Countries with a strong pickup point culture (France, Poland, Nordics) often reach even higher success rates.
Rural or southern regions may naturally perform lower.
How to improve it
Encourage customers to use pickup points — they dramatically improve delivery reliability.
Validate addresses more strictly at checkout (missing apartment numbers are a common issue).
Choose carriers with better last-mile coverage in your target country.
Send proactive delivery notifications with time windows or options to redirect.
Add an “address line 2” prompt if you see repeated failed attempts in specific regions.

4. Customs Clearance Time
What it measures
Customs clearance time tracks how long shipments spend in customs before they’re released to the local carrier. It’s the gap between “arrived at customs” and “cleared for delivery.”
Why it matters for the EU market
For non-EU sellers, this is one of the biggest sources of unpredictable delays. Even when your carrier is fast, slow customs processing can add 1–5 extra days (sometimes more). And unfortunately, customers don’t differentiate — they just see a “late delivery.”
Common reasons for longer clearance times include:
incomplete or incorrect documentation,
wrong HS codes,
no IOSS number when required,
missing product descriptions,
duty or VAT mismatches.
If customs clearance is slow, every other KPI — OTD, transit time, WISMO rate — will suffer.
How to calculate it
Customs Clearance Time = Delivery scan timestamp after customs − Arrival scan timestamp at customs
You’re basically measuring the time between “package entered customs” and “package released.”
Quick example:
A parcel arrives at EU customs on March 3 at 10:00.
It clears customs on March 5 at 14:00.
That’s a clearance time of 52 hours (a little over 2 days).
Across hundreds of parcels, you’ll normally track the average clearance time.
Typical benchmarks
24–48 hours is typical for well-prepared shipments with correct paperwork.
3–5 days is common when documentation is inconsistent or carriers batch-clear shipments.
Anything above 5 days suggests a recurring documentation or carrier-process problem.
How to improve it
Use IOSS for low-value shipments — it removes many tax-related hold-ups.
Make sure HS codes and product descriptions are clean, specific and consistent.
Work with carriers that pre-clear shipments or offer digital customs processing.
Avoid vague product names (e.g., “accessory” or “gift”) — they trigger manual checks.
Monitor customs times by country.
5. Tracking Visibility Rate (Tracking Events Completeness)
What it measures
Tracking visibility rate shows how many of your shipments have complete, clear and timely tracking events from pickup all the way to delivery. In other words: Can your customer (and you) actually see what’s happening with the parcel?
A shipment with missing scans, late updates or vague status messages counts as “low visibility.”
Why it matters for the EU market
European customers rely heavily on tracking — more than many sellers expect. If they can’t see where their parcel is, they usually assume something went wrong. That leads to:
more WISMO inquiries,
lower satisfaction scores,
more negative reviews on Amazon and other platforms.
For non-EU sellers, tracking visibility is especially important because cross-border shipments pass through multiple carriers and systems. If one handover isn’t properly scanned, the entire tracking chain goes dark. This KPI is one of the strongest predictors of customer trust.
How to calculate it
There’s no single “official formula,” but the simplest practical version is:
Tracking Visibility Rate = (Shipments with complete tracking events / Total shipments) × 100
You define what “complete” means — for example:
pickup scan,
customs arrival & clearance (when relevant),
handover to local carrier,
out-for-delivery,
delivered.
Quick example:
You shipped 400 orders.
340 have full tracking events from pickup to delivery.
60 are missing key scans (often at customs or last-mile handover).
Your tracking visibility rate is:
(340 / 400) × 100 = 85%
In cross-border shipping, 85 percent is okay, but improving it will clearly reduce support tickets.
Typical benchmarks
90–95% is strong for EU-bound cross-border parcels.
Anything below 80% usually results in noticeably higher WISMO volume.
Local deliveries within the EU often reach 95–98% because they use a single carrier network.
How to improve it
Choose carriers with reliable data integrations and real-time API updates.
Avoid carriers that frequently “drop” tracking during handovers.
Send proactive notifications even when the carrier doesn’t — it fills visibility gaps.
Standardize your tracking milestones so you can compare carriers side by side.
For high-value or sensitive shipments, pick services that guarantee full event tracking.

6. Order Defect Rate (ODR)
What it measures
ODR shows the percentage of orders that result in a “defect” — meaning the customer had a bad enough experience to trigger a complaint, return, negative review or other issue counted by the platform you sell on.
On Amazon, ODR includes things like:
negative feedback,
A-to-Z claims,
chargebacks.
In short: ODR reflects how often something goes wrong from the customer’s perspective.
Why it matters for the EU market
ODR has a direct impact on your seller health — especially on Amazon. High ODR can reduce your Buy Box chances, cause account warnings or even suspensions. And here’s the kicker: many “defects” are actually caused by logistics issues, not product issues.
The biggest drivers of ODR for non-EU sellers are:
late deliveries,
missing or poor tracking,
customs delays,
failed first delivery attempts,
damaged items due to long transit routes.
This KPI ties together everything happening in your delivery pipeline.
How to calculate it
Platforms vary slightly, but the general formula is:
Order Defect Rate = (Number of defective orders / Total orders) × 100
Quick example:
You fulfilled 1,000 orders last month.
15 triggered defects (negative reviews, A-to-Z claims, complaints linked to delivery issues).
Your ODR is:
(15 / 1,000) × 100 = 1.5%
On Amazon, the target is below 1%, so 1.5 percent is a warning sign.
Typical benchmarks
Amazon expects ODR to stay under 1%.
Most healthy EU-focused sellers sit around 0.3–0.8%.
Sellers relying heavily on long-distance cross-border shipping often struggle to stay below 1% unless their carriers and processes are very stable.
How to improve it
Improve OTD and tracking — most “defects” originate from poor delivery experience.
Use carriers with strong performance in your key EU lanes.
Make delivery promises more realistic (overly optimistic timelines hurt ODR fast).
Add better packaging for long-haul shipments to reduce damage claims.
Respond proactively to late-delivery complaints — quick resolution can prevent a defect from being escalated.

7. Return Rate (Delivery-Related Returns)
What it measures
Return rate shows how many orders come back to you — but here we're focusing only on returns caused by delivery issues, not product quality. This includes things like:
“address not found,”
“customer refused the parcel,”
“delivery attempt failed multiple times,”
long delays that made the customer cancel or return the order.
It helps you understand how often logistics (not the product) is the root cause.
Why it matters for the EU market
Europe has one of the highest return rates in the world, especially in e-commerce. Customers also expect a smooth, almost effortless returns process. When deliveries take too long, arrive damaged or never reach the customer, the return rate climbs quickly.
For non-EU sellers, this KPI is extra important because long transit distances and customs steps naturally introduce more points of failure. And every return is expensive — you lose the item or have to re-import it, you refund the order and you may take a hit to your seller metrics.
Delivery-related returns are often the hidden cost of cross-border shipping.
How to calculate it
Delivery-Related Return Rate = (Number of delivery-related returns / Total shipped orders) × 100
Quick example:
You shipped 500 orders in a month.
35 were returned due to delivery issues (failed attempts, wrong address, long delays, refusal).
Your rate is:
(35 / 500) × 100 = 7%
For cross-border EU sales, 7 percent is on the high side — it normally indicates address quality issues or unstable last-mile performance.
Typical benchmarks
For delivery-related returns:
2–5% is common for EU cross-border shipments.
Anything above 5% usually signals deeper issues with address accuracy or last-mile carriers.
Fashion and apparel tend to have higher return rates overall — but logistics-related returns should still stay low.
How to improve it
Use an address validation tool at checkout — missing apartment numbers are a huge driver of returns.
Offer pickup point delivery, especially in countries like France, Poland, Belgium and the Nordics.
Provide clear, proactive tracking updates so customers don’t refuse late parcels.
Choose carriers with strong first-attempt delivery success in your target countries.
Investigate return reasons regularly — patterns appear quickly (e.g., certain cities or carriers causing the issue).
8. Cost per Shipment (Total Landed Cost)
What it measures
Cost per shipment tells you how much you actually spend to deliver one order to an EU customer. But to make this KPI meaningful, it should include all parts of the cost — not just the carrier fee.
That means:
shipping cost (international + domestic),
customs duties (when applicable),
VAT handling or IOSS fees,
processing fees,
surcharges (fuel, remote areas, peak season),
return handling costs.
When all these pieces are included, you get what’s often called the total landed cost.
Why it matters for the EU market
Cross-border deliveries to Europe can be surprisingly expensive — and the true cost is often higher than sellers expect. Without tracking this KPI, you may have solid sales but poor margins because your logistics cost grows faster than your revenue.
It’s also common for sellers to underestimate unpredictable fees: customs holds, long-distance returns, or last-mile surcharges in certain EU countries. This KPI helps you see if your pricing, shipping model and carrier choices actually make financial sense.
How to calculate it
Cost per Shipment = (Total logistics costs for a period / Total shipped orders)
To get a more realistic number, make sure “total logistics costs” include all charges tied to shipping.
Quick example:
Last month, you shipped 600 orders to the EU.
Your total logistics spend (shipping + customs + VAT handling + returns + fees) was $9,000.
Your cost per shipment is:
$9,000 / 600 = $15 per order
If your average order margin is $12, you’re losing money on each delivery — a common pitfall for new EU sellers.
Typical benchmarks
These vary a lot depending on product size and destination, but general trends look like this:
$8–$15 per shipment for small/light products using economy cross-border services.
$12–$25 for tracked, faster services.
$4–$8 for EU-based fulfillment (because you remove the long-distance leg).
Returns from the EU back to non-EU countries can be very expensive — often $10–$20 on their own.
How to improve it
Compare different carriers by total cost, not just the line-haul price.
Use IOSS to streamline VAT and reduce customs confusion.
Consider shipping in bulk to an EU fulfilment centre for your top sellers.
Reduce failed delivery attempts — they’re surprisingly costly.
Optimize packaging size. A slightly smaller parcel can drop your rate tier significantly.

10. Customer Inquiry Rate (WISMO Rate)
(WISMO = “Where Is My Order?”)
What it measures
This KPI shows how many customers contact you (or your support team) asking where their order is, why it’s delayed or why tracking isn’t updating. It’s essentially a “stress signal” from your buyers saying:
“Something doesn’t feel right with my delivery.”
Even if your other KPIs look fine, a rising inquiry rate usually means customers are experiencing confusion or uncertainty.
Why it matters for the EU market
European customers expect transparent, timely tracking updates. When they can’t see where their parcel is — especially with cross-border shipments — they quickly reach out. A high inquiry rate often points to deeper issues such as:
tracking gaps between carriers,
slow customs clearance,
unclear delivery timelines,
inconsistent last-mile performance,
over-optimistic promised delivery dates.
For non-EU sellers, reducing WISMO contacts is one of the fastest ways to improve customer satisfaction and reduce support workload.
How to calculate it
Customer Inquiry Rate = (Delivery-related inquiries / Total shipped orders) × 100
Quick example:
In a month, you shipped 1,200 orders.
Your support team received 96 delivery-related questions.
Your inquiry rate is:
(96 / 1,200) × 100 = 8%
For cross-border shipping, 8 percent is on the higher side and normally means customers aren’t getting enough clarity or updates.
Typical benchmarks
3–6% is common for EU cross-border shipments.
Below 3% usually indicates excellent tracking visibility and predictable delivery times.
Above 8–10% signals that customers are confused or worried about delivery progress.
How to improve it
Provide more detailed, proactive tracking notifications — especially during customs or carrier handovers.
Make your delivery window realistic based on real data, not estimates.
Give customers alternate delivery options (pickup points reduce both delays and inquiries).
Fix tracking gaps by choosing carriers with better event visibility.
Add a simple, automated “Where’s my package?” tracking page so customers don’t need to contact support.
How Flex Logistics helps you improve these KPIs
If you're planning to grow in the EU market, you’ll quickly notice one thing: European customers expect fast, predictable delivery. And most of the KPIs we talked about (OTD, transit time, WISMO rate, returns, even ODR) depend on how close your inventory is to the buyer.
Shipping all the way from the US or Asia to France or Germany can work when you’re just starting out. But keeping those deliveries consistent as you scale? That gets tough. Long transit times, customs checks and handovers between carriers make it hard to maintain stable performance. That’s why so many non-EU sellers eventually move part of their inventory into Europe. It’s the easiest way to speed up delivery, cut unpredictability and instantly improve most of your logistics KPIs.
And this is exactly where we can help.
At Flex Logistics, we run fulfilment warehouses in Germany, France, the UK and Poland. You can rent storage space from us and handle operations yourself — or you can let us take over part (or all) of your fulfilment flow, including picking, packing and returns. You choose the setup, and we make sure it works smoothly.
Storing inventory inside the EU doesn’t just make shipping faster. It makes your entire logistics pipeline more reliable — and that’s what European customers expect from top-tier sellers.
If you want to improve your delivery performance in the EU, reach out to us. We’d be happy to talk through the best setup for your store.

Conclusion
Selling to customers across the EU can feel like a big step, especially when you’re shipping from outside Europe. Different countries, different delivery expectations, and plenty of things that can slow a parcel down along the way. But once you start tracking the right KPIs, the whole process becomes much easier to understand — and much easier to improve. You don’t need a giant dashboard to stay on top of your logistics. A small set of well-chosen KPIs can tell you everything you need: which carriers are doing a good job, where delays are creeping in, how long customers really wait and what’s hurting the experience.
The most important part is building a habit. Check your KPIs regularly, compare results between countries, and tweak your setup as you grow. Small adjustments often translate into big improvements for customers.
And if you ever feel like cross-border shipping is holding you back, remember that you don’t have to keep all your inventory overseas. Moving products into Europe — even partially — can instantly make your delivery faster, more predictable and much more competitive. At the end of the day, good data makes good decisions. Track the right KPIs, keep an eye on your trends, and you’ll know exactly what to do next to level up your EU logistics.
