The ultimate ecommerce checkout guide for customers like this guy

Cart abandonment is the nemesis of ecommerce. With 70% of carts left stranded, every tweak to your checkout process can lead to significant revenue recovery. 

Here's how to create a seamless experience, win over customers, and boost conversions.

PSST! If you like what you see but don’t want to have to read it, here’s a FREE downloadable guide (in checkbox format for your convenience) for all you skimmers out there. We seriously won’t ask you for a credit card… or anything, really.

Building a frictionless checkout experience

A smooth checkout makes all the difference. Start by optimizing the basics:

  • Mobile optimization: With mobile commerce projected to hit $856 billion by 2027, a mobile-friendly interface is non-negotiable. Use auto-resizing pages, finger-friendly buttons, and readable fonts.
  • Guest checkout: Avoid forcing account creation. New customers are wary of commitments—provide a guest option to keep things simple.
  • Address autocomplete: This one’s huge. Tools like Smarty's US and International Address Autocomplete save time and prevent errors, reducing friction at a critical moment.

Checkout features that drive sales

Beyond the basics, these elements make the checkout process delightful and trustworthy:

  • Trust signals: Include security badges, SSL certificates, and clear return policies. Over 25% of abandonment stems from site distrust.
  • Transparent pricing: Hidden fees? Big nope. Show shipping costs upfront to avoid cart shock.
  • Multiple payment options: From digital wallets to buy-now-pay-later, cater to customer preferences. With 13% of carts abandoned due to limited payment options, this is a must.

Tackling cart abandonment

It hurts when customers leave, but recovery is possible:

  • Abandoned cart emails: Send a 3-part email sequence starting an hour after cart abandonment.
  • Exit-intent popups: Offer discounts or incentives just before a customer bails.
  • Retargeting ads: Remind shoppers what they’re missing with personalized ads.

Selling it psychologically

Sometimes, just the upfront nature of your site can give a person all they need to trust you and purchase your product or services:

  • Display security badges: Especially for first-time visitors, they want to know that you aren’t going to sell their information or steal their identity to get that new car they always dreamed of. Put security badges where customers can see them and trust you and your product from the first encounter with your site.
  • Install promotion clock countdowns: Get your customers to buy sooner rather than later with a countdown for the end of a promotion.
  • Provide customer reviews: Get that bandwagon effect rolling and show your new site visitors how much others loved what’s sitting in their cart. Nothing says, “Buy me!” quite like 50 other positive reviews.

When all else fails…

customer support chat is important

Customer support is the secret sauce to success when your other systems might miss the mark:

  • Live chat during checkout: Sometimes, customers just have a quick question about your products and services. If a real human can answer those quickly, you just might land the sale.
  • Display contact info prominently: Getting ahold of you should be the last thing they are worried about if they encounter an issue buying your product. Put that phone number, email, and chat bubble in a loud and proud location.
  • Enforce quick response times: Nobody wants to wait more than 24 hours to buy a pair of pants. Let’s answer those questions quickly.

Address data: Your ecommerce secret weapon

Accurate address data is the silent hero of ecommerce. Use address verification and geolocation tools to pre-fill forms, provide precise delivery times, and personalize shipping promotions. Smarty's solutions ensure every address is valid and verified, eliminating delivery mishaps and boosting operational efficiency.

TL;DR: Simplify, optimize, convert

Don't forget to do this high-five.

Our guide is much more detailed, so if you still feel like there’s more to be discovered, you’re right! 

Ecommerce success comes down to simplicity, speed, and security. From mobile-friendly designs to robust address tools, these best practices create a checkout process that customers love. 

Also, don’t forget to keep it real. Stay human and genuine in your customer service approach and features. Be helpful and consistent while still making shopping fun. That’s what will make you memorable.
