What is Shopify Functions?

Shopify Functions is a tool for merchants that allows them to customise and extend the Shopify platform, enhancing customer cart and checkout processes to meet specific business needs. This tool enables businesses to create unique and personalised shopping experiences.

In the ever-evolving world of eCommerce, businesses are constantly seeking innovative ways to create unique shopping experiences that cater to their specific needs. Shopify Functions is a powerful tool that enables merchants to extend and customise the Shopify platform, offering unparalleled flexibility and control. This feature allows businesses to tailor their customer cart and checkout processes to meet bespoke business logic, ensuring a seamless and personalised shopping experience.

Shopify Functions empowers merchants to securely customise various aspects of the eCommerce journey, including product discounting, product bundles, delivery options, and payment rules. By leveraging Shopify Functions, merchants can enhance their online stores with tailored solutions that drive customer satisfaction and boost sales. 

In this blog post, we delve into the capabilities of Shopify Functions and explore its transformative impact on the eCommerce industry.

Key Benefits of Shopify Functions

For eCommerce businesses, Shopify Functions offer a superior way for merchants to tailor their stores with unique and customised experiences. Here are some of the key benefits:

Enhanced Customisation

Shopify Functions empower merchants to create bespoke shopping experiences by customising elements like product discounting, product bundles, delivery options, and payment rules. This level of personalisation ensures that stores can meet the specific needs and preferences of their customers.

Admin UI Integration

Merchants can access admin UI elements that work in tandem with Shopify Functions. This integration simplifies the process of managing and implementing custom functions, making it more accessible for merchants to enhance their online stores.

Compliance and Validation

Although currently in developer preview, Shopify has announced that Functions will enable checkout and cart validation. This feature allows merchants to write rules that ensure orders and carts comply with specific business requirements. For example, merchants can enforce rules for exclusive and limited products, such as limiting a product to only one per customer.

By leveraging these capabilities, Shopify Functions provide merchants with the tools to create highly customised and compliant shopping experiences, driving customer satisfaction and boosting overall sales.

Archie Rose Case Study: Applying Shopify Functions for Bulk Discounts

For Archie Rose, a premium distillery known for its bespoke spirits, offering customers bulk discounts when ordering a case instead of a single bottle was crucial. This strategy aimed to enhance customer satisfaction, encourage larger purchases, and streamline the shopping experience. To achieve this, MindArc utilised the Product Discount API within Shopify Functions to create a seamless and effective.

MindArc's developers designed sophisticated logic within the Shopify Functions framework. The system first checks if the products added to the cart are eligible for the bulk discount by verifying predefined criteria set by Archie Rose. It then assesses whether the quantity of eligible products meets the required thresholds for a bulk discount. Once these conditions are confirmed, a percentage discount is automatically applied to the total cart value.

By leveraging Shopify Functions, Archie Rose significantly improved the overall customer experience. Customers can easily see discounts applied in their cart without having to enter discount codes manually, reducing friction and enhancing satisfaction. The visible and automatic discount incentive encourages customers to purchase in larger quantities, driving higher AOV. Automating the discount logic also reduces the need for manual intervention, allowing Archie Rose's team to focus on other strategic areas of the business.

The automated system supports scalability, allowing Archie Rose to handle increased traffic and order volumes without compromising performance. By offering unique and attractive pricing options, Archie Rose can differentiate itself in a competitive market, attracting and retaining more customers.

The case study of Archie Rose illustrates the transformative impact of Shopify Functions on eCommerce operations. By strategically leveraging the Product Discount API, Archie Rose not only met a critical business requirement but also enhanced the overall shopping experience for its customers. This approach exemplifies how advanced eCommerce functionalities can support business growth, operational efficiency, and customer satisfaction.

Leveraging Shopify Functions to Achieve Business Goals

Shopify Functions offer powerful capabilities that allow businesses to meet specific goals and objectives, enhancing their eCommerce operations through tailored solutions. Here are a few ways Shopify Functions can facilitate key business goals:

Product Bundling

Shopify Functions enable merchants to group products together and sell them as a single unit. This is particularly useful for businesses aiming to increase AOV and promote complementary products. By creating bundled offers, merchants can provide customers with better value while boosting sales of related items.

Personalised Delivery Experience

With Shopify Functions, businesses can offer a personalised delivery experience to their customers. For instance, merchants can generate local pickup delivery options tailored to customers' locations, providing convenience and enhancing the overall shopping experience. Additionally, Shopify Functions allow merchants to rename delivery options, making them more intuitive and appealing to customers. This flexibility ensures that delivery options align with the brand's voice and meet customer expectations. 

Here’s a client example where the requirement is to be able to hide specific rates on certain addresses. The function code fetches the customer address input in checkout, and then does a check that’s reconciled in the admin interface to ultimately, call an operation to hide delivery rates.

Payment Customisation

By leveraging Shopify Functions’s Payment Customisation features, you can create a more intuitive and efficient checkout process, leading to higher customer satisfaction and improved sales performance. Shopify Functions allow you to enhance your checkout experience. This allows you to tailor the payment options displayed to buyers, ensuring a seamless and personalised transaction process. 

You can easily hide specific payment methods that are not relevant to your customers, streamlining the checkout experience and reducing confusion. You can also reorder payment methods to highlight preferred options, improving the overall conversion rate. Additionally, renaming payment methods to align with your brand voice or provide clearer descriptions helps customers better understand their choices.

Navigating Challenges in Implementing Shopify Functions

While Shopify Functions offers a range of powerful capabilities for customising and enhancing eCommerce operations, businesses may encounter several challenges during implementation. These can be found in detail on Shopify's official documentation. Being aware of these constraints is essential for planning and executing a seamless integration.

Security Concerns

Manipulating prices based on line item properties continues to pose a security risk, similar to the issues experienced with Shopify Scripts. During the solution design stage, merchants must be vigilant about potential vulnerabilities and ensure that appropriate security measures are in place to mitigate these risks.

Steep Learning Curve

The learning curve for Shopify Functions can be quite steep, especially for those new to the platform or to headless architecture. It is recommended that businesses engage capable and experienced merchants who are familiar with Shopify Functions. This expertise is crucial for effectively implementing and leveraging the full potential of these advanced features.

Addressing the Challenges

To successfully implement Shopify Functions and overcome these challenges, businesses can take the following steps:

  1. Engage Experienced Developers: Hiring or partnering with developers who have a deep understanding of Shopify Functions can significantly reduce the learning curve and ensure that the implementation is carried out efficiently and securely.

  2. Thorough Planning and Testing: Careful planning and rigorous testing are essential to identify and address any potential security risks or limitations. This includes understanding the constraints outlined in the Shopify documentation and designing solutions that work within these parameters.

  3. Ongoing Education and Support: Continuously educating the development team about the latest updates, best practices, and security protocols related to Shopify Functions will help maintain a robust and secure eCommerce environment.

  4. Leverage Community and Resources: Utilising the wealth of resources available through Shopify’s developer community, including forums, documentation, and support channels, can provide valuable insights and solutions to common challenges encountered during implementation.

By proactively addressing these challenges, businesses can harness the full power of Shopify Functions to create customised, secure, and efficient eCommerce experiences that align with their strategic goals.


Shopify Functions marks a notable advancement from Shopify Scripts, offering controlled cart and checkout logic customisation. Despite development limitations, Shopify continually improves its functionalities. While mastering Shopify Functions may pose a learning curve, its benefits in customisation and improved customer experiences are significant.

Businesses can achieve various objectives through Shopify Functions, from enhancing product bundling to personalised delivery options and custom payment rules. However, challenges like security concerns and the learning curve require careful planning and collaboration with experienced developers.

Overall, Shopify Functions empower businesses to customise and optimise their eCommerce operations. By addressing implementation challenges, businesses can unlock new growth opportunities and succeed in the evolving digital landscape.
