Testing a Complete Kit Bundle in Shopify without adding an app
One of the simplest improvements I found in a Shopify store came from looking at how customers were actually buying. What I found was that they were often purchasing parts of the same setup separately.
A common example of this was purchasing front and rear seat covers first, and then a month or two later buying the centre console item as a separate purchase. This was happening across a range of products including best sellers.
I had several questions. Were they forgetting to buy the console cover the first time? Was it unclear that it was a separate item that had to be added to cart separately?
I knew there must be a way to improve this buying journey and the customer experience.
The hypothesis #
In-store customers would often purchase front and rear covers along with the centre console in a single transaction. I wanted to be able to offer this same purchase option online and came up with the idea to test a Complete Kit option.
My hypothesis was that a clearly labelled Complete Kit would make the full setup easier to recognise and select. It could also encourage a higher-value purchase and potentially simplify fulfillment by reducing separate console cover orders later. A merchandising experiment worth running...
To keep things simple in the beginning, I would only test this on my most popular product ( rather than rolling the change out across the entire catalogue). A benefit of this approach was that I already had good sales data for the chosen product and it would keep the test contained.
Before making any changes, I looked at historic sales data for this product to use as a baseline for the experiment.
How I created a complete kit option in Shopify using product variants #
The product already used variants to offer different seat types e.g. front covers, rear covers, front and rear sets and standalone console covers.
I added new variants for “Complete Kit” which covered the front, rear and centre console bundle. The description clearly stated the contents and the correct price was set across the available fabrics.
I updated the variant description for the front and rear option without a console, to help the customer choose between the options.
Lastly, I updated the “Seat Type” section of the product description to list the complete kit bundle and its contents.
All of these changes used the existing store and product setup, without adding another app.
Results over the first 180 days #
The early signs were promising. In the first 180 days, Complete kits accounted for 63% of full set units sold (12 of 19). This early uptake supported testing the same approach across other popular models.
The sample was small, so I treated this as an encouraging uptake signal rather than a conclusive result.
What I learned from the project #
One of the key lessons I learned was the importance of regularly reviewing your store analytics and customer buying behaviours.
Good ecommerce optimisation isn’t always about adding more products or more features.
Sometimes it’s about understanding what the customer is trying to achieve and making the right purchase option clearer.
