Checkify Pro vs Checkify Plus: Key Differences Explained

Checkify.pro positions itself as a customizable single-page checkout for Shopify merchants. An active subscription to this platform is required. Sellers benefit from Shopify’s robust CRM, app store and custom apps, and the support of its established community and experts.

While Checkify.pro operates within the one ecosystem, Checkify.plus does not need a specific platform to operate. This customizable one-page checkout solution is designed for online sales across a variety of industries and niches. By offering a wide range of out-of-the-box features, it makes a bold move to capture market share from established eCommerce platforms. Launched in spring 2025, Checkify.plus is experiencing steady growth, with many merchants using both Checkify products, but in different contexts.

Conclusion: a draw.

Checkify.plus offers complete flexibility when it comes to managing multiple stores or web properties. Merchants can connect and sell via any number of storefronts, landing pages, email campaigns, social media, etc. from a single Checkify.plus account, making it ideal for businesses operating across different brands, domains, or sales channels. This approach significantly reduces complexity and allows for a streamlined workflow and faster setups.

On the other hand, Checkify.pro follows a more strict “one store – one account” rule, meaning each new store requires its own separate setup. While this principle aligns well with Shopify’s structure, it may present limitations for merchants managing multiple storefronts under one organization.

Conclusion: advantage, Checkify.plus.

Both Checkify.pro and Checkify.plus are fast checkout pages, but Checkify.plus has the upper hand when it comes to raw speed and responsiveness.
The reason lies in the architecture. Checkify.pro relies on real-time communication with the eCommerce platform to fetch product data, pricing, discounts, inventory details, and various other settings, attributes and parameters. This constant back-and-forth introduces extra requests and responses before and during the checkout process, which can slightly slow things down.

Checkify.plus, on the contrary, has all critical data stored internally. Product properties, discounts, and configurations are managed within the platform itself, eliminating the need for external calls. As a result, page loads and interactions are noticeably smoother and faster, giving users a frictionless experience that can potentially impact conversions.

Conclusion: advantage, Checkify.plus.

When it comes to upselling and offering additional paid options during checkout, both Checkify.pro and Checkify.plus deliver very similar functionality. Merchants can create tailored offers, add extras, and increase average order value through strategic prompts within the checkout flow.

However, there is a notable difference at this stage. Checkify.pro includes a one-click upsell feature, along with a ‘second chance’ offer (an additional pop-up that appears if the initial upsell is declined). This can be particularly effective for squeezing out extra conversions without disrupting the user experience.

Currently, this specific upsell mechanism is not available on Checkify.plus. While its upselling capabilities are still strong, the absence of the one-click and second chance features at the checkout stage puts it slightly behind in this aspect.

Conclusion: advantage, Checkify.pro.

Stability is where Checkify.plus really shines. With no reliance on Shopify or any other third-party platform mechanics, the risk of unexpected errors is significantly reduced. Everything is self-contained: no external dependencies, no fragile connections, just a solid, well-tested and predictable checkout flow.

Checkify.pro, in contrast, can occasionally run into issues, most of them outside of Checkify’s direct control or issues that are really hard to detect, test and troubleshoot. The sources of such problems can be different, for example:

- custom Shopify themes that interfere with how the checkout is triggered;
- modified or missing “add to cart” logic that breaks the connection to the checkout flow;
- API rate limitations.

With Checkify.plus, the logic is built in, the environment is controlled by its developers, and the bugs caused by platform quirks simply cannot exist.

Conclusion: advantage, Checkify.plus.

Both Checkify.pro and Checkify.plus provide tools for managing orders directly within their respective dashboards. Merchants can easily track and review purchases, ensuring awareness, access to data and smooth post-purchase experience.

However, there is a slight difference in scope. With Checkify.pro, the order handling process (fulfillment, tagging, status updates) is typically managed outside the app, through Shopify itself. Shopify’s native order management tools are irreplaceable for it.

Since Checkify.plus operates independently, it needs to cover more ground. This includes additional built-in functionality for handling orders end-to-end, especially in scenarios where no external eCommerce platform is present. That added flexibility gives merchants more control directly within Checkify.plus.

Still, for most use cases, both solutions get the job done well.

Conclusion: a draw.

Checkify.pro handles abandoned checkouts and buyer notifications and retention by leveraging Shopify’s built-in tools and third-party integrations. Popular platforms like Klaviyo, Postscript, Yotpo (SMS Bump), Omnisend, and others can be connected to manage email and SMS marketing, create custom flows, and re-engage hesitant shoppers. The email sending process depends on Shopify's ecosystem almost entirely, which may bring some limitations.

Checkify.plus, in contrast, offers native solutions for managing abandoned checkouts and retention emails, which are built directly into the platform and available for all customers at no extra costs. Merchants have access to powerful automation tools without needing to rely on external services. At the same time, Checkify.plus still supports the same suite of third-party integrations, so, if the native features are insufficient, it is always possible to work with more sophisticated and professional tools.

This dual approach gives merchants more versatility, independence, and fine-tuned control over how and when they communicate with actual buyers or those who abandon checkouts.

Conclusion: advantage, Checkify.plus.

With Checkify.plus, products and their variants are managed directly within the app. Sellers can set up their physical items, digital products or even services, configure options, and adjust details, all without relying on an external platform. This self-contained system gives merchants full control, especially useful for those not tied to traditional eCommerce ecosystems.

Checkify.pro gets data from a Shopify product catalogue. Merchants create and edit products within their CRMs, and Checkify.pro pulls the necessary data in real-time. For those already operating inside Shopify, this is convenient and fits seamlessly into existing workflows.

Ultimately, neither approach is inherently better. It depends on the business case. Sellers who prefer a fully integrated Shopify experience may stick to the platform, while those wanting more autonomy and flexibility might favor Checkify.plus.

Conclusion: a draw.

Both Checkify.pro and Checkify.plus support payment acceptance through some of the world’s most popular and trusted processors, including Stripe, PayPal, and Adyen. Merchants can offer buyers a wide range of payment options, such as express checkout buttons, buy now pay later, credit and debit card payments, as well as dozens of local and alternative payment methods.

Additionally, both solutions enable manual payment options, often known as “cash on delivery”, providing flexibility for merchants serving different markets or for those who have no Stripe, PayPal or Adyen account.

Checkify.plus has ambitions to expand its payment processor offerings beyond the current set, aiming to bring even more options to its users. However, these enhancements are not yet live or widely available to all customers.

Conclusion: a draw.

The two eComm solutions have a similar pricing model. It consists of a fixed part and a variable, usage-based part, billed weekly.

Both fixed subscription and variable transaction costs of Checkify.pro are quite diverse, offering several plans and the option to request a custom plan for large, enterprise-level businesses.

Checkify.plus, by contrast, offers just two plans with a minimal fixed weekly fee and slightly higher transaction fees. The key advantage is that a single subscription includes even more features out-of-the box. This helps businesses cut down on additional software expenses, reduce complexity, and stay focused on what truly matters: selling.

Conclusion: advantage, Checkify.plus.

They bear a similar name but address different pain points for online sellers. Shopify fans may surely continue with the .pro version, while those seeking more flexibility, speed, and platform independence will find a strong ally in Checkify.plus.
