At SmartSize, our goal is to make size and fit guidance simple, accurate, and effortless for every merchant.
Most customizations are easy to implement through our app. However, some merchants require advanced customization, such as placing the Size Chart button in a very specific location on their store’s Product Page.
This type of request falls under Premium Support, which is included only in our Enterprise plan.
Below, we explain why.
Every Shopify theme is unique
Shopify themes vary greatly in structure, code organization, and integration logic.
When merchants request a custom button placement, our team must:
Review and understand the store’s theme
Identify the correct insertion point for the code
Adjust the solution to the merchant’s layout and styling
This requires deep knowledge of Shopify theme architecture and can differ dramatically from theme to theme.
To properly customize the button location, our team must:
Analyze theme files
Insert and adapt code
Test the solution across devices (e.g. desktop + mobile)
Test across different browsers
This work requires time, expertise, and careful QA to ensure a smooth shopper experience.
Additional adjustments are common
After installation, merchants often request further refinements:
Minor repositioning
Alignment updates
Styling adjustments
Changes after theme updates
These iterations take additional time from the team and must be handled by experienced technical staff.
Why isn’t this included for all plans?
To keep SmartSize accessible, we maintain a competitive price across all plans.
However, highly tailored technical work—especially when it requires theme-level analysis and custom coding—is resource-intensive.
For this reason, Premium Support (custom implementation & adjustments) is available exclusively to Enterprise merchants that keep this subscription for 3 months.
This helps us:
Maintain fair pricing for all users
Provide high-quality service where advanced support is required
Ensure fast & reliable technical execution
