How Smartphone Accessory Brands Combine Product Design and eCommerce Innovation

Managing smartphone accessory collections takes careful planning. Explore how brands connect product design, inventory management, customer behaviour, and eCommerce strategies to build more organised online stores.

It could be easy to assume that an accessory such as a phone case should be an easy sell. As long as it looks great, fits well, and offers a decent level of protection, it should be a breeze. However, as you’ll see below, there can be a lot of hidden complexity.

Smartphone cases are quite different to many other fashion accessories. Whilst you may desire to buy a certain pattern, you may find that it doesn’t work with your phone. Or you may find that despite buying the right phone case, you’re unsure of the differences between the levels of protection.

As identified in an eCommerce UX benchmark by the Baymard Institute (2026). 65% of mobile and 61% of desktop sites tested had poor or average navigation on their homepages and category pages. The research was carried out on over 180 top eCommerce sites in the USA and Europe.

By really thinking about your product design, you can take advantage of the opportunities presented to give your customers a great experience.

The Hidden Complexity of Phone Cases

Product design is becoming a key element in this category. The range of finishes, patterns, bold designs, and colours means that your customers can look great in their products.

However, this can cause some issues:

If your accessory business has 40 unique patterns, 6 phone models and 3 protection options, then you have 720 variations to think about. This can quickly get complicated.

You may need to create a product for each variation. This can cause complications with your product inventory, compatibility, images, and availability.

Considerations When Designing Products

Rather than just creating new designs, you can think about how these designs will fit into your product range. By creating a recognisable style, your products can look great across multiple phones and accessories.

However, you shouldn’t create products that are interchangeable.

Depending on the level of protection, some phone cases may be more appropriate for your customers. If the patterns are the same, you will need to make sure that you clearly explain the differences between them.

A great way to help with this is by using a product variation matrix. This helps you to see where your products are falling short. By creating a matrix of your designs, phone models, case styles, and finishes, you can see where there are gaps in your product range. This can help your team know which variations need to be photographed.

The aim isn’t to limit choice, but to make it easy for you and your customers.

Improved Product Discovery Based on Device Compatibility

One of the biggest issues with selling phone accessories online is that products can look similar but have very different compatibility.

Due to slight differences in phone cameras, buttons, and size, your phone cases may not fit other phone models.

Many online stores will have wide categories. This can cause confusion for your customers.

A much better way is to start with device compatibility.

BURGA have created a specific range for iPhone 18 Pro Max cases. This makes it easy for your customers to see what designs are available.

This shows you that your product compatibility should determine what products your customers can buy. Once they’ve found compatible products, you can let them choose which one they like based on the design, colour, finish and protection.

Ensure products are easy to find using effective filters, product search and a logical naming convention. Compatibility information should be included on the product pages and in the basket so that your customers can easily see what they are choosing.

Mobile users can be complicated. If your product has lots of drop-down filters and long lists of filters, customers will struggle to find the right device.

The best way to know if your phone accessory site will work is to ask yourself this question.

Could a new customer find a compatible accessory without needing to understand how your stock is organised?

If the answer is no, then adding more products may not help improve the experience.

How to Make Products Look Great

Phone accessories are very visual products. Using images will help your customers to see the pattern, texture and finish.

However, this may not always be helpful.

A lifestyle image may help your customers to see how your phone cases will fit into their outfits and workspaces. However, it will rarely explain anything about the construction. Your customers may still need to know about the edges, camera cutout, material, and charging compatibility.

This can cause issues when there are different variations of your product.

The solution is to ensure your product images form part of your information architecture.

Your product galleries should be consistent. This will ensure your customers can easily understand what your product looks like. Having a main image will help them see the design, and having extra images will show them the sides, camera, finish, and other details.

Having consistent angles will make it easier for your customers to see the differences.

Product Descriptions

If you’re using generic descriptions such as high quality or good protection, this won’t help your customers much. Instead, by explaining what materials your product is made from, what charging it supports, and what design features it has, your customers will have a better understanding.

Having consistent product images and descriptions will help your team add new ranges. This will also minimise any mistakes being made.

The best product pages will not only entice your customers but will also answer any questions they may have.

New Smartphones Pose a Challenge

Every time a new flagship smartphone comes out, there will be new demand for compatible accessories. However, this can create a difficult situation for your business.

You’ll need to update your phone case designs to fit the new phone. This can include changes to the size, camera cutout, button alignment, and product specs. Even existing designs may need to be changed to fit the new hardware.

Your hired eCommerce team will need to create new product listings, images, navigation, inventory, and fulfilment.

Whilst these are all related, they can all be at different stages.

You may have products ready to sell but not have the images. Or you may have a range page ready to publish but not have accurate inventory. Your customers may also see multiple phone case variations for different generations of devices but struggle to see what phone they work with.

This isn’t just an issue with your website. This shows there is a gap between your product and your retail.

A better way to handle this would be to ensure you have:

• Confirmed compatibility
• Images
• Accurate inventory
• Consistent product listings.

This will create a point to check when launching your new range.

Also consider how your new range will impact your existing ranges. Not all of your customers will upgrade their smartphones straight away. Removing old phone models from your navigation can make it harder for your customers to find compatible accessories.

The aim is to cater for the new demand whilst keeping your catalog easy to use.

This shows that your eCommerce innovations don’t just need to be on your website. You can improve the processes to ensure your customers will receive accurate products and information.

Use Customer Behaviour to Decide What to Put in Your Next Range

Once your accessory range is up, you can use customer behaviour to see if your assumptions were right.

Often businesses focus on how many products are being sold. However, this may not tell you everything.

You may have a popular design, but not many customers are purchasing. This could be because there aren’t many devices available, your customers don’t understand the protection, or you’re running low on stock.

To find out why this is happening, you’ll need to look at other factors.

You can see what products, colours, or accessories your customers are searching for by looking at their search terms. You can also get an insight into what designs your customers like by looking at engagement on your product pages. Questions and returns can help you see what information you’re missing.

Looking at all of these factors together can help you understand what is going on.

If your customers are searching a lot for a certain colour but aren’t purchasing much, you may think you need to create more designs. However, on further inspection, you may notice that this colour isn’t available on the devices with the most interest.

A better solution could be to increase compatibility for this design.

If your customers are frequently asking about magnetic charging, this could mean you need to improve your product information.

You can use the data you have collected from your eCommerce site to improve your designs.

Instead of designing products in isolation, you can look at what your customers are buying, searching for, and asking. This can help you improve your future ranges.

This isn’t just about seeing numbers. If your conversion rate has dropped recently, you wouldn’t want to redesign your product page. Or if your searches have increased but only temporarily, you wouldn’t want to create a new range.

However, by knowing what patterns are happening, you can make real improvements.

Make Complex Choices Easy

Often when talking about phone accessories, we focus on trends, new materials, and increasing our ranges. Whilst this is important, there is more to it.

The great online store has a well-planned structure to ensure that the product design, compatibility, merchandising, stock, and customer feedback are all in harmony.

The biggest opportunities for innovation may not be obvious. However, by improving your product selector, product gallery, and inventory, you can really improve how your customers interact with your brand.

The aim for accessory retailers should be to make it easy for your customers to find the right choices.

Ultimately, by creating great products, your customers will want to purchase. By using smart eCommerce innovations, you can help them find, understand, and purchase with confidence.
