Abandoned carts in OpenCart: simplify checkout

On average most shoppers who put something in the cart never complete the order. Some can’t be won back, they were just comparing prices. But the default six-step accordion checkout in OpenCart on its own loses a noticeable share of people who were ready to buy.

What gets in the way in the default checkout

  • six steps with a “Continue” button after each; on a phone that’s six rounds of scrolling and tapping;
  • the “register or guest” choice on the first step: the customer hasn’t ordered yet and is already asked about an account;
  • extra fields: fax, company, second address line, region; for most deliveries you don’t need them;
  • the delivery address is typed by hand with nothing to help;
  • errors appear after submitting instead of right next to the field.

What checkout should look like

  • one page: contacts, shipping, payment and the summary visible at once;
  • a minimum of fields: name, phone, address; e-mail if you need it;
  • a phone mask with the country code so the number can’t be mistyped;
  • city and pickup point chosen by search with suggestions, not a dropdown of thousands of rows;
  • guest checkout by default, an account as a checkbox;
  • shipping cost and total update instantly when an option changes.

That’s how my one-page checkout module for OpenCart 3 works.

Find out where customers drop off

In Google Analytics 4, set up the add_to_cart, begin_checkout and purchase events. If people reach begin_checkout but not purchase, the problem is the checkout itself. If most drop off in the cart, look at shipping costs and the terms shown there.

Also test checkout on a phone with a slow connection. That’s often where you notice the “Confirm” button hiding under the keyboard.

Win back those who didn’t finish

Even a perfect checkout won’t remove every drop-off. The customer may have closed the payment page or the bank may have declined the card. These people are worth a reminder by e-mail or message with a “Pay now” button while the purchase is still on their mind. That’s what the abandoned and unpaid order module does.

If orders with online payment disappear from the admin, that’s a different problem, covered in a separate article.

FAQ

Can checkout be one click?

Yes, for some products that works well: the customer leaves only a phone number and a manager calls back. For a store with shipping and online payment, a full but short form usually works better.

Will a new checkout module break my theme?

The module hooks in via OpenCart events and ships its own styles, so it works with the default theme and most themes based on it. I can test it on a copy of your store before you buy.

Rather not dig into it yourself?
