Our time-to-market improved by 40%.” James Okonkwo CEO, Multi-Brand Retailer | UK Start Your Success Story FAQ Product development questions, answered directly How is my intellectual property (IP) protected in China? Protecting your innovation is our top priority. We utilize comprehensive Non-Disclosure Agreements (NDAs) with all participating factories and internal staff. By acting as your on-the-ground supply chain consultant in China, we maintain strict control over who has access to your designs, ensuring your unique ideas remain confidential throughout the production cycle. Design files are shared only with the specific factory working on your project and under documented agreements. How long does the full product development process take? A typical product development timeline ranges from 6–12 weeks depending on product complexity. Feasibility assessment takes 3–5 days, factory matching and vetting 7–14 days, prototyping 7–21 days (depending on iterations), and trial production 2–4 weeks. We'll provide a detailed timeline tailored to your specific product during the assessment phase. Complex molded or tooled products may require additional time for mold development. What if my first batch sells out quickly — can I reorder fast? Yes. Because we've already completed the development groundwork — factory relationship established, tooling in place, packaging specs finalized — reorders move directly into production with dramatically reduced lead times. Our ongoing relationship with the factory means your order gets priority scheduling, and our QC infrastructure is already calibrated to your product specifications. How do you handle communication across different time zones? Our bilingual team operates on the ground in China during local business hours, providing same-day responses to your inquiries. You'll have a dedicated project manager who consolidates all factory communication into clear English updates. We use real-time messaging for urgent items and structured weekly reports for production status — so you never wait overnight for critical answers. What types of products can you help develop? We develop products across consumer electronics, home goods, textiles and apparel, hardware and tools, furniture, toys, health and beauty, sports equipment, and packaging. From sewn and handmade products to molded and tooled components — our factory network spans Shenzhen, Guangzhou, Yiwu, and Ningbo manufacturing hubs covering virtually every product category. How are production costs calculated and what's included? We provide a complete, itemized cost breakdown for every project — sampling fees, tooling and mold costs, per-unit production cost, testing and certification fees, custom packaging, carton specifications, domestic China logistics, international freight estimates, and service fees. Nothing is bundled or hidden. Every line item is explained so you can make fully informed decisions at each stage of development.
