Problem
Business and private customers need to see prices with different tax wording, and the theme showed the same text to everyone. Products with colour options also showed no colour choice on product cards or in filters.
Solution
I added theme settings for the tax text and a customer tag that marks business customers, then showed the right label on product prices, the cart and search. For colours, I made cards, the variant picker and filters draw swatches from the product's colour option, using the variant image when there is one. I also added deferred loading for scripts and fixed header, pagination and footer details.
Key decisions
Chose customer tags for the tax label
Why The label follows the logged-in customer, so one theme serves both audiences.
Chose editable tax text in theme settings
Why The client can change the wording without a developer.
Chose swatches built from existing product options
Why No new product data was needed.
