FAQ
Common questions about FXTech and our services.
What kind of company is FXTech?
FXTech (Shenzhen Feixing Keyao Technology Co., Ltd.) is an e-commerce technology agency based in Shenzhen and a Shopify Partner. We help cross-border e-commerce companies and brands expanding overseas with Shopify / Shopify Plus development, Headless DTC storefronts, website performance optimization, and cross-border VAT compliance systems.
Who are your clients?
Mainly cross-border e-commerce companies and brands expanding overseas, from early-stage DTC sellers to established brands that need custom systems. The team has worked with clients in fashion, beauty, electronics and home goods, with 100+ clients to date.
Should I build on Shopify or on an open-source storefront?
If you want to launch quickly, keep operations light, and your business processes fit the Shopify ecosystem, Shopify / Shopify Plus is usually the better choice. If you have higher requirements for the shopping experience, business workflows, data ownership or platform fees, a Headless storefront built on an open-source framework such as MedusaJS is worth considering. We look at your business stage and team first, then make a recommendation; we do not start from a preset answer.
Can you optimize performance without rebuilding the site?
Yes. Performance optimization is a standalone service: we establish a Core Web Vitals baseline (LCP, INP, CLS, TTFB), locate the bottlenecks, then optimize images, JavaScript, CSS, caching and CDN on the existing site, and keep tracking the metrics before and after. This applies to both Shopify stores and self-built sites.
How do we get started, and how is pricing calculated?
Describe your needs via the Telegram, email or phone listed on the contact page. We discuss your business goals and current state first, then provide a proposal and quote based on the scope. Because the degree of customization varies a lot from project to project, we do not offer fixed package prices.
Do you work in English and with overseas teams?
Yes. The team works in both Chinese and English and can collaborate remotely with overseas operations, design or engineering teams.
