Beyond Off-the-Shelf: Custom WooCommerce Functionality
WordPress and WooCommerce offer incredible power to UK businesses, providing a flexible and scalable foundation for e-commerce. The vast library of available plugins promises a solution for almost any requirement. But many business owners know the reality: you install a plugin to solve one problem, another to solve a second, and a third to bridge the gap between them. Soon, your website is slowed down by bloated code, you’re managing multiple subscriptions, and the “solution” still doesn’t quite fit your unique workflow.
There is a better alternative. Instead of stacking generic tools, a lightweight, bespoke plugin can provide the exact functionality you need. It’s often a more efficient, secure, and perfectly tailored solution.
At Barrett Solutions, we specialise in developing custom WooCommerce functionality that solves the specific, real-world challenges our clients face. Here are a few examples of how we’ve extended the power of WooCommerce with purpose-built tools.

Case Studies in Custom WooCommerce Functionality
These examples show how a targeted, bespoke plugin can solve problems that generic tools often can’t.
Case Study 1: Increasing Average Order Value with a Smart Cart Upsell
These examples show how a targeted, bespoke plugin can solve problems that generic tools often can’t.
- The Business Problem: A key client, We Love Collectibles (WLC), noticed that customers buying trading cards often forgot to purchase essential, high-margin accessories like card sleeves, binders, or protective cases. They needed a way to suggest these items at the most relevant moment without being intrusive.

Case Study 2: Managing Scarcity with a "One Per Customer" Purchase Limit
The first step was an on-site audit to understand the physical reality of the buildings and the environment. It was immediately clear that a wired connection from the main office to an external access point would be the only viable solution to bypass the signal-blocking walls.
- The Business Problem: In the world of collectibles, high-demand, limited-edition products are common. WLC needed a robust way to prevent a single buyer from purchasing all available stock, ensuring fair distribution among their customer base and preventing frustration.

The Bespoke Solution: We added a simple checkbox and an optional expiry date field to the WooCommerce product inventory tab. When enabled for a product, the plugin enforces a strict “one per customer for their lifetime” rule. Our solution is thorough; it checks at every possible point:
- When a user tries to add the item to their cart.
- If they try to update the quantity in the cart.
- Crucially, it checks the billing email against all past orders during the final checkout process.
Case Study 3: Enhancing Product Pages with Integrated Video Galleries
The result was immediate and decisive. Once the externally mounted primary mesh unit was powered on, the other two mesh units inside the warehouses connected instantly. The client now has full-speed, reliable Wi-Fi coverage even at the furthest reaches of their warehouse properties.
This successfully resolved a long-term issue that had been a major source of daily frustration, and the client was extremely happy with the outcome. This project highlights that a robust solution for Wi-Fi for metal buildings often relies on expert physical installation and creative problem-solving, not just the technology itself.
- The Business Problem: The standard WooCommerce product gallery is excellent for images, but WLC wanted to embed videos—like product unboxings, reviews, or showcases—directly within the gallery to provide a richer experience and increase buyer confidence.
- The Bespoke Solution: We developed a robust plugin to add a simple meta box on the product edit screen where the client can paste multiple YouTube video URLs. On the front-end, the plugin automatically fetches the video thumbnails and adds them to the product gallery. When a user clicks a video thumbnail, the main image area is replaced with the embedded YouTube player.
- The Business Outcome: This piece of custom WooCommerce functionality creates a far more engaging and informative product page. Customers can see the product in action without leaving the page, which helps increase time-on-page and can directly contribute to a higher conversion rate.
Our Approach to Building Bespoke WordPress Plugins
These solutions work well because they are purpose-built. Our development process for creating custom WooCommerce functionality is focused on efficiency and precision:
- Understanding the Bottleneck: We start by analysing the specific business process or workflow that is causing friction.
- Writing Clean, Efficient Code: Build what’s needed, and nothing more. This avoids the code bloat that can slow down your website.
- Using WordPress Best Practices: Implementing the correct hooks and filters to integrate our code with WordPress and WooCommerce. This ensures compatibility and makes future updates smoother.
- Creating Simple Admin Interfaces: The backend controls for our custom plugins are designed to be intuitive for you and your team to use directly within the familiar WordPress dashboard.


Invest in a Solution That Truly Fits Your Business
The WordPress plugin ecosystem is vast, but sometimes the most effective, secure, and fastest solution isn’t another off-the-shelf product. A bespoke plugin, designed to solve your specific problem, can be a powerful investment in your business’s efficiency. Building out custom WooCommerce functionality is a core part of what we do.
If you’re wrestling with a WooCommerce limitation or a workflow that generic plugins just can’t solve, it might be time to consider a tailored approach. The right tool can make all the difference, and often, the right tool is one that is built just for you.
We find that many businesses need custom WooCommerce functionality when they want to take their e-commerce operations to the next level.
