IT Case Study

In today’s era of rapid information development, efficient office software is crucial for the growth of enterprises. Haidongxinxi is a tech pioneer from Chengdu China that deeply understands this. The company focuses on "professionalism" as the core philosophy of its products and services. Dedicated to developing office software products that meet the needs of various industries, the company has observed the growing demand for digital document management. 


Soon, Haidongxinxi plans to launch a comprehensive, easy-to-operate, and highly compatible multi-platform PDF editing tool. This tool is intended to provide users with a practical and efficient PDF editor to facilitate effective information management and further improve work efficiency and document processing professionalism.

Haidongxinxi needed a stable and efficient PDF SDK as the core capability provider for its Windows platform office product. This SDK must secure functional performance while saving internal development time. It should have market-tested features and a standardized UI interface for direct user access, enabling rapid integration to shorten the product development cycle and expedite time-to-market.


Haidongxinxi had specific expectations when looking for a partner:


         - Availability of a mature and market-approved PDF SDK product: This is a critical aspect the company considers while evaluating PDF SDK providers. They seek a long-term partner to avoid future changes due to technical issues.

         - Authorization for commercial sale: As a tech company providing professional office software, the ability to sell products is a vital cooperative condition. ComPDFKit’s flexible licensing is also a major advantage.

         - Cross-platform SDK with consistent user experience: Supporting multiple platforms is prepared for future business expansion. Choosing a PDF SDK provider with support for multiple development platforms saves the trouble of searching for new partners later.

         - UI: Haidongxinxi wanted a readily usable and user-friendly UI. ComPDFKit not only provides standardized UI but also supports UI customization.


Among many competitors, ComPDFKit won the favor of Haidongxinxi with its professional PDF solutions, thus becoming a trusted partner. Haidongxinxi is confident in the partnership with ComPDFKit and looks forward to continuous collaboration in the future.
