AI-Powered supplier vetting

SummaryShenzhen Yibote Information Technology Co., Ltd. is a China-based limited trading company established in 2017, with six employees and a product scope covering IT networking and optical-fiber communication equipment. It provides 3D software design and multiple forms of customization, including full customization, but reports no new products in the past year. Quality assurance, complaint-handling procedures, supplier-service procedures, and corrective/preventive-action records are documented. However, finished products are checked by packing staff, and raw-material traceability identification is absent. The supplier reports export activity for eight years and derives 90% of total sales from exports, but the information also states that it has no valid import/export license, creating an unresolved export-compliance concern. Financial information confirms records for 2022–2024 but does not provide assessable performance figures. No customer cases or clear certification holdings are provided. The supplier...

Supplier typeThe supplier is identified as a limited company and trading company, with six employees and a business scope centered on IT networking, communication, office, and information-system-related products and services. Its offered products include routers, switches, wireless access points, VOIP phones, optical-fiber communication products, and smart meeting tablets.

R&D capabilityThe supplier reports no new products during the past year. Although it has R&D-related customization capability, the explicit absence of recent new-product development indicates insufficient evidence of active product innovation.

It also confirms the ability to provide 3D software design services, providing direct evidence of broad customization support.
