BigCommerce Legacy Checkout Sunset: What You Need to Know

BigCommerce is officially retiring Legacy Checkout on February 28, 2025. If your store is still using it, you’ll need to switch to a modern checkout solution to avoid disruptions and maintain a smooth customer experience.

This change is part of BigCommerce’s effort to enhance security, performance, and compliance with the latest PCI DSS 4.0 standards. While some store owners may find the transition straightforward, those with custom checkout setups, third-party integrations, or legacy payment providers may face challenges.

That’s where WebDesk Solution comes in. As an experienced BigCommerce development company, we specialize in seamless checkout migrations, ensuring that your store transitions smoothly without downtime or lost functionality.

In this blog, we’ll cover why BigCommerce is making this change, key deadlines to be aware of, and how our team at WebDesk Solution can help make this transition hassle-free.

Why Is BigCommerce Sunsetting Legacy Checkout?

BigCommerce is retiring Legacy Checkout to ensure stores are equipped with a faster, more secure, and conversion-friendly checkout experience. The eCommerce industry has evolved significantly, and outdated checkout systems can slow down transactions, increase security risks, and limit growth opportunities.

Evolution of eCommerce Checkout Experiences

Over the years, customer expectations around checkout have changed. Shoppers today demand:

• Faster and frictionless checkout experiences to reduce cart abandonment.
• Secure payment processing to protect their data and build trust.
• Mobile-optimized checkouts for seamless shopping on any device.

To keep up with these expectations, modern checkout solutions must offer speed, security, and flexibility—something Legacy Checkout lacks. BigCommerce’s Optimized One-Page Checkout is designed to meet these evolving demands, providing a better experience for both store owners and customers.

Limitations of Legacy Checkout

The Legacy Checkout system was built on outdated technology that no longer meets today’s eCommerce standards. Some of its key limitations include:

• Security vulnerabilities – Legacy Checkout does not comply with the latest PCI DSS 4.0 requirements, making stores more susceptible to fraud and security risks.
• Limited customization options – Many store owners rely on checkout customizations that Legacy Checkout does not fully support.
• Incompatibility with modern payment solutions – Many newer payment gateways and checkout enhancements do not work with Legacy Checkout.
• Performance issues – A slow or outdated checkout can increase cart abandonment rates and lost sales.

By retiring Legacy Checkout, BigCommerce is ensuring that all merchants have access to a secure, optimized, and future-proof checkout experience.

For store owners still using Legacy Checkout, this transition is not just necessary—it’s an opportunity to upgrade to a checkout solution that drives higher conversions and a smoother customer experience.

Key Dates and Timeline for the Sunset

BigCommerce has set a final deadline of February 28, 2025, for the retirement of Legacy Checkout. After this date, all stores still using it will be automatically migrated to the Optimized One-Page Checkout, which may impact customizations, third-party integrations, or payment settings.

Official Announcement from BigCommerce

BigCommerce officially announced the sunset of Legacy Checkout in early 2024 as part of its plan to enhance checkout security, performance, and compliance with new standards. Store owners were encouraged to begin migrating as soon as possible to avoid last-minute issues.

Important Deadlines for Store Owners

• Now – February 27, 2025: Store owners should review their checkout setup and start planning the transition if they are still using Legacy Checkout. This is especially critical for those with custom checkout workflows or third-party integrations, as adjustments may be required.
• February 28, 2025: BigCommerce will disable Legacy Checkout completely. Stores that haven’t transitioned will be automatically switched to the Optimized One-Page Checkout, which could affect checkout functionality if not properly prepared in advance.

Is Your Store Affected? Here’s How a WebDesk Solution Can Help!

Not sure if your store is affected by the Legacy Checkout sunset? Here’s the simple truth: If your BigCommerce store is still using Legacy Checkout, you need to take action before February 28, 2025. Otherwise, you risk unexpected checkout changes that could impact your sales, customer experience, and store functionality.

Who Needs to Take Action?

While some store owners may have a smooth transition, others will need to act quickly to prevent disruptions. Your store is likely affected if:

• You are still using Legacy Checkout – After the deadline, it will no longer be available, and your store will be automatically moved to BigCommerce’s Optimized One-Page Checkout.
• You have custom checkout features – If you’ve made modifications to your checkout process, they may not work after the transition.
• You rely on legacy payment gateways – Some older payment providers may not be compatible with the new checkout system.
• You use third-party apps or integrations – Any checkout-related BigCommerce apps or plugins connected to Legacy Checkout might stop working.

If your store falls into any of the above categories, waiting until the last minute could result in checkout issues, lost sales, or a broken user experience.
