When adding new features to your storefront, choosing between an app store install and custom Shopify theme customization impacts your site speed and balance sheet.
1. Financial Comparison: Recurring Fees vs One-Time Code
Five $30/month apps cost $1,800 every single year. Replacing them with custom Liquid sections is a one-time investment that pays for itself in months.
2. Impact on Mobile PageSpeed & Google Rankings
Every app adds external scripts, stylesheets, and tracking calls that degrade mobile Core Web Vitals.
3. When an App Makes Sense vs Custom Code
Complex systems like Klaviyo email syncing or subscription recurring gateways justify apps; UI features like sticky buttons, FAQ accordions, and cart upsells should always be custom Liquid.
