Headless Commerce
An architecture that separates the front end (what the customer sees) from the back end (catalog, payments, inventory). Gives full freedom in design and channel integration.
In practice
Headless suits stores that have outgrown what a template can offer. Cost: expensive development plus ongoing maintenance. Most stores don't need it.
Common misconception
'Headless is mandatory for serious stores.' 99% of stores don't need it. Shopify and WooCommerce meet 99% of needs. Headless fits stores with $1.5M+ in annual revenue.
How to fix it
Considering headless? (1) What problem does your platform not solve? (2) Costs: $55-140K in development plus ongoing maintenance, (3) alternatives: a custom theme, Shopify Hydrogen.
Example
A fashion chain moved to headless because its theme didn't support 3D view and AR try-on. Development took 8 months and cost $220K. CR +18%, load time 40% faster. Worth it — but only at scale.
Priority
Don't consider headless before $1.5M+ in annual revenue. Before that, invest in a professional custom theme and optimization.
