What is headless commerce?
Decide whether your store needs a separate frontend or whether an existing theme can meet your goals.
( when it helps )
Start with the experience your store needs.
Custom UX
Build buying guides, content-led shopping or multi-brand journeys when a theme makes them difficult to manage.
Connected systems
Connect content, product search, inventory and customer systems through APIs, with clear ownership of each integration.
Multi-channel reuse

| Area | Headless commerce | Theme-based store |
|---|---|---|
| Frontend | Custom app, often Next.js, connected by APIs | Theme or template tightly coupled to backend |
| Performance | Depends on frontend code, APIs and hosting | Depends on theme, apps and platform behavior |
| Flexibility | Control over custom journeys and integrations | Build within theme and platform extension points |
| Maintenance | Requires frontend engineering ownership | Lower engineering overhead |
| Useful when | A separate frontend solves a clear requirement | Existing storefront features cover the requirements |

Common questions
Is headless commerce better than Shopify themes?
Consider headless for custom journeys, multiple channels or integrations that are difficult to maintain within a theme. A well-built theme is often simpler for a standard catalog or a team with limited engineering capacity.
Which backend can power a headless storefront?
Common choices are Shopify, Shopify Plus, Magento, BigCommerce, WooCommerce, and custom commerce APIs.
Does headless commerce improve SEO?
It gives you control over rendering and page structure, but does not automatically improve search visibility. Crawlable content, metadata, redirects and performance still need to be implemented and checked.
What does headless commerce cost?
Udaan typically scopes headless commerce from $8k to $35k depending on catalog complexity, integrations, checkout, content model, and migration needs.
Can checkout stay on Shopify?
Yes. A custom storefront can use Shopify checkout. Confirm that required payment, subscription and checkout features support your chosen setup.
When should a brand avoid headless?
Avoid headless if the catalog is simple, the team cannot maintain a custom frontend, or a theme already meets performance and conversion goals.
