Abandoned carts: how to get more checkouts completed
Why shoppers leave products in the cart without buying — and what you can change in your online store to keep them.

Key takeaways
- Unexpected costs at the last step are one of the most common reasons shoppers leave.
- Guest checkout, without a mandatory account, removes friction.
- Familiar payment methods and trust signals matter a lot.
- A reminder email, with the customer’s consent, brings back some purchases.
A shopper found the product, added it to the cart… and left. Abandoned carts are one of the most common and most expensive problems for any online store: the visitor was already very close to buying.
Some people are just comparing prices and will leave whatever you do. Many, though, leave for reasons you can fix. Here are the most common ones and what you can change.
1. Unexpected costs at the end
Shipping, cash-on-delivery fees or other charges that appear only at the last step create distrust. The fix:
- show shipping costs or a shipping calculator on the product page or in the cart,
- clearly state the free-shipping threshold, if there is one,
- don’t add charges the customer doesn’t expect.
2. Mandatory account creation
Many shoppers don’t want yet another password. Allow guest checkout and offer account creation after the purchase, in one click, explaining the benefit (order tracking, faster future checkouts).
3. A complicated checkout
Every unnecessary field is a reason to stop. Check:
- are you asking only for what’s necessary?
- does browser autofill work?
- is it easy on mobile, with the right keyboard for each field?
- are errors shown clearly, next to the field that needs fixing?
4. Few or unfamiliar payment methods
If customers don’t find their preferred method, they may leave. Offer the essentials: cards, digital wallets such as Apple Pay and Google Pay, and in some markets cash on delivery. Any redirect to a bank page should be quick and return correctly to the store.
5. Lack of trust
Especially with a new store, shoppers want reassurance:
- full business details and easy contact,
- a clear returns policy,
- customer reviews,
- a secure connection (HTTPS) and a professional look at every step.
6. A slow or buggy page
A checkout that lags or freezes on mobile costs sales. Measure the speed of your cart and checkout pages and test a complete purchase regularly.
7. Reminder emails
When the shopper has given their email and consent settings allow it, a short, friendly email listing the items in their cart can bring back some purchases. Keep it simple: what they left, a link to continue and contact details for questions. One or two messages are enough.
Measure to improve
With the right Google Analytics set-up you can see at which step most shoppers leave. If they leave at the cart, look at costs; if they leave at payment, look at payment methods and speed. Change one thing at a time and measure again.

Frequently asked questions
Can I email people who left products in their cart?
Yes, as long as the customer gave you their email and data-protection rules are respected. The email should be helpful, not pushy, and include an easy way to unsubscribe.
How many steps should checkout have?
As few as possible without leaving out anything necessary. Often one or two well-organised screens are enough: details, shipping, payment and a clear summary.
Does free shipping help?
Often, yes, because it removes one of the most annoying “surprise” costs. A free-shipping threshold can also raise the average order value.
