FAQ
Common questions
Which platforms do you build on?
Headless storefronts on Next.js connected to commerce backends like Shopify, Medusa, or custom APIs — you get platform reliability with none of the theme limitations.
Can you handle international payments?
Yes. Multi-currency routing, localized payment methods, and checkout flows tuned per region — which directly reduces payment rejections abroad.
Will the store survive a flash sale?
That's the point of the architecture. Edge caching and load testing mean traffic spikes hit the CDN, not your backend.
Can you migrate our existing store?
Yes. Products, customers, and order history move over in a staged migration with URLs and SEO preserved throughout.
