We provide comprehensive "cross-border company maintenance" services for Guangdong-Hong Kong dual-license vehicles. Whether it's the mainland business license, company seal, and tax account required during application, or the Hong Kong company's CI, BR, and seals, we assist you in managing them properly. Subsequent services include annual industrial and commercial reporting, address leasing, and timely tax filing for mainland companies, as well as full-service maintenance for Hong Kong companies—including registered agent services, address provision, annual returns, and business registration renewal.
