You can have great products, a well-designed website, and customers ready to buy. But if your checkout process creates frustration or doubt, you could be losing sales without realizing it.
Many business owners hear that around 70% of shopping carts are abandoned and assume they need to recover every lost cart. But not every abandoned cart represents a lost sale. Some shoppers are simply browsing.
The bigger opportunity is identifying the customers who genuinely wanted to buy but ran into a problem that stopped them.
Here are five checkout problems that could be quietly costing your e-commerce store sales, along with practical ways to find and fix them.

1. Unexpected Costs That Surprise Customers
Imagine a customer finds exactly what they want, adds it to their cart, and starts checking out. Everything looks good until the final step, when shipping, taxes, or additional fees suddenly increase the total.
Even if those costs are completely reasonable, the surprise can damage trust.
Customers want to understand what their purchase will cost before they get too far into the checkout process. When the final amount is different from what they expected, they may decide not to complete the order.
What to Check
Walk through your checkout and ask yourself:
- Can customers estimate shipping costs before reaching the payment step?
- Is your free shipping offer easy to understand? Do customers know how much they need to spend or which products qualify?
- Are taxes and additional fees displayed before the final screen?
- Is the full purchase cost easy to find early in the process?
Sometimes, fixing this problem does not require a major technical change. You may simply need to make existing information easier to find.
The goal is to help customers understand their total cost before they invest time entering their information.
2. A Checkout Process That Feels Like an Obstacle Course
When customers reach checkout, they are already showing interest in buying. This is not the time to make them jump through unnecessary hoops.
A long or complicated checkout can frustrate customers who were ready to complete their purchases. Requiring them to create an account can add another barrier.
Every additional field, confusing instruction, or unnecessary step gives customers another reason to leave.
What to Check
Go through your checkout on a desktop computer, mobile phone, and tablet. Then ask yourself:
- Do you really need every field in your checkout form?
- Can you simplify the information customers must enter?
- Does the address form follow the format customers expect in the countries you serve?
- Is guest checkout available and easy to find?
- Are customers forced to create an account before they can buy?
Guest checkout is particularly important. Some customers do not want to create an account just to make a purchase.
Your checkout should collect the information you need to fulfill orders and provide good customer service, without asking customers to do more work than necessary.
It is also worth asking someone unfamiliar with your website to test the process. You and your team know how the checkout works, which can make confusing steps harder to notice.
3. Checkout Bugs That Only Appear in Certain Situations
Placing one successful test order does not prove that your checkout works for every customer.
Some problems only appear when specific conditions come together. A particular product, coupon code, shipping method, payment gateway, or customer address might trigger an error that your team has never encountered.
For example, checkout might work perfectly for a customer ordering one product within your usual shipping area. But what happens when someone orders 50 products, uses a coupon, selects a different shipping method, or enters an address outside your normal geographic area?
If you only test the simplest scenario, you could miss problems that prevent real customers from completing their purchases.
What to Check
A more thorough checkout test should include different combinations of:
- Browsers and devices, including Android and iPhone
- Logged-in and guest customers
- Shipping methods and delivery locations
- Coupons that are applied and removed
- Payment methods
- Small and large shopping carts
- Different product combinations and unusual address details
The goal is to simulate the variety of situations your customers might encounter.
Platforms such as Magento, WooCommerce, and X-Cart have multiple components working together during checkout. Testing only one successful order can leave important gaps in your quality assurance process.
You may not discover a problem until a customer experiences it, and that customer may leave without telling you what went wrong.
4. Payment Errors That Make Customers Give Up
Sometimes checkout technically works, but a payment problem still costs you the sale.
A credit card might be declined. A payment gateway might time out. A digital wallet might stop working.
The error itself does not have to mean a lost sale. What matters is what happens next.
If customers receive a vague message such as “Payment failed,” they may not know how to fix the problem. If the checkout erases everything they entered and sends them back to the beginning, the frustration can be enough to make them abandon the purchase.
What to Check
Test what happens when a payment fails, and ask yourself:
- Does the error message explain what the customer needs to fix?
- Are errors specific to the problem, such as an incorrectly entered phone number?
- Does the checkout preserve the customer’s address and other information?
- Can the customer easily try another payment method?
- Do you offer payment options your customers actually want to use?
Depending on your audience, useful options might include digital wallets, PayPal, Venmo, Apple Pay, or buy now, pay later services.
Think about how customers shop, too. Someone ordering from a phone may prefer a payment option they can access without getting out their credit card.
Clear instructions, preserved information, and convenient payment choices can make it easier for customers to recover from a problem and finish their orders.
5. A Checkout Experience That Doesn’t Feel Trustworthy
Trust is not something you create by adding a security badge to your checkout page. It is something you maintain throughout the entire buying experience.
Customers may hesitate when something about the payment process feels unfamiliar or confusing. Often, they will not contact customer support to explain why. They will simply leave.
Small details can create doubt at exactly the wrong moment.
What to Check
Look for anything that might make a customer question whether it is safe to complete their purchase:
- Does the checkout page suddenly look different from the rest of your website?
- Are customers redirected to an unfamiliar-looking payment screen?
- Is your return policy visible and easy to find?
- Do your buttons clearly explain what happens next?
- Is the order total easy to understand and consistent with what customers expect?
- Is there a clear indication that payment information is handled securely?
For example, a button labeled “Continue” may leave customers wondering what happens next. A more specific label, such as “Place Order,” makes the action clearer.
These issues are not just about trust badges. They involve your design, wording, and the way your e-commerce platform is configured.
Your checkout should feel like a natural continuation of your website, not a confusing or unfamiliar experience that makes customers second-guess their decision.
How to Find Checkout Problems on Your Own Website
You do not have to guess whether your checkout is creating problems. You can start by experiencing it the way a new customer would.
Here is a simple exercise to try:
- Pull out your phone and open a different browser, if possible.
- Visit your website as a brand-new customer.
- Do not use an existing customer account or an admin account.
- Choose a product and go through the buying process.
- Pay attention to anything confusing, frustrating, or unexpected.
Notice when shipping costs appear, how many fields you must complete, whether payment options are easy to find, and whether anything makes you hesitate before placing the order.
Then ask a business friend who has never purchased from your website to do the same thing. Their experience may reveal problems you and your team have overlooked simply because you are so familiar with your own checkout.
You may be surprised by what you discover.
Small Checkout Improvements Can Make a Difference
You do not necessarily need a complete website redesign to improve your checkout experience.
Start by finding the obstacles that prevent willing customers from completing their purchases. Make costs clear, remove unnecessary steps, test more than one checkout scenario, improve payment error messages, and make sure customers feel confident when entering their payment information.
Most importantly, do not assume that a successful test order means everything is working as it should.
Your checkout is one of the most important parts of your e-commerce website. Giving it a closer look can help you identify problems that are easy to overlook but costly to ignore.
