Container Loading

Customer Testimonials

»GQC really makes a difference.«

"We have cooperated with several quality assurance companies before, but GQC really makes a difference.
Besides precise detection of classical defects down to the smallest details,  GQC clearly understands concepts and ideas of all different kinds of consumer products, so that they can identify those weaknesses and advise on complications/challenges for end consumers during the actual use of the product. This ability and support is a significant value adding service for us. In addition, we are positively surprised by GQCs' proactive communication and immediate on site feedback when significant issues have been detected, enabling us to react quickly and saving valuable time. Thank you very much for your great support."

Customer Testimonials

»GQC has far exceeded our expectations«

"GQC has far exceeded our expectations. GQC incorporated all our specific requests and added additional check points based on years of experience in the lighting industry. The arrangement of  the inspection appointment was made possible within a very short notice and the communication thereof was conducted in a very humble and professional manner. The inspection report with specific and realistic recommendations arrived within 24h of the inspection itself and was conclusive for the end buyer to make a decision upon accepting the goods despite minor deviations. Great job and we will continue to use GQC services in the future."

– Florian Heike, General Manager of Celinius Co., Ltd. (Taipei)

»We are now doing all quality inspection with GQC.«

"Finding the right quality inspector in china took some time for us. At the end it was kind of luck, that we have made Stephan and his company GQC. I was connected to him thanks to a sourcing agent. After the first inspection we have seen that they really pay attention at what they do. Not only have they delivered a fantastic report, but they also had great ideas on how to improve the quality. We are now doing all quality inspection with GQC."

Customer Testimonials

»I recommend GCQ.io 100%!«

"As a first-time physical product founder I went through incredible hurdles. One of them was not being able to visit China for factory and production review. Stephan and his team at GQC have been a trusted resource to count on to make sure production was on point before shipping to 36 countries. On top of that, Stephan's team helped me cut costs and timings of sample reviews from different factories by avoiding international shipping, increasing our speed of execution across several prototyping rounds of LITO CASE | Foldable Suitcase. I recommend GCQ.io 100% for the quality control of your product."

– Marco Fazio Founder of Lito Case
