When they realized their software architecture was outdated, they turned to SEQTEK to lead the modernization of their Legacy order system. Our client was using an old application purchase order system based on Microsoft Access that was being licensed every year. With the legacy application, only one person could use it at a time, making it a hassle to enter loads of data. The application was struggling with the scaling needs of our client. This outdated system was causing errors, missed opportunities, and frustration was at a head within the company. THE SOLUTION They trusted SEQTEK to develop a solution to deploy an updated application on their internal server so multiple users could access it simultaneously. SEQTEK’s team built the application using .NET Core and React to modernize the architecture and create an intuitive interface for their users. Several changes and enhancements were made that were not possible on the older application. There are several advantages to migrating from a legacy application to a .NET Core framework, including: - **Added Security** - **Faster Speeds** - **Cloud and DevOps Optimization** - **Support for Modern Architecture** SEQTEK integrated with the company's existing SQL Server and deployed to their Windows environment using IIS.   THE OUTCOME Our client offered a better user experience for their purchasing department. Originally, the user had to enter the same data multiple times in different areas of the system. SEQTEK streamlined the data entry process to remove the risk of duplicate data entries. Also, this solution provided a simpler architecture for future features to be created. With this new application, our client stopped paying the yearly legacy licensing fee. We have been able to identify multiple processes or features that can now be created in a fraction of the time that changes on the old application would have required.   [Manufacturing](https://blog.seqtek.com/casestudy/tag/manufacturing) ## Related posts [![](https://blog.seqtek.com/hs-fs/hubfs/Case%20Study%20API.png?height=200&name=Case%20Study%20API.png)](https://blog.seqtek.com/casestudy/making-data-and-apis-easy) [Data](https://blog.seqtek.com/casestudy/tag/data), [Software Development](https://blog.seqtek.com/casestudy/tag/software-development), [Legacy](https://blog.seqtek.com/casestudy/tag/legacy), [Tech Debt](https://blog.seqtek.com/casestudy/tag/tech-debt) ## [Goodbye Tech Debt, Hello Profitability!](https://blog.seqtek.com/casestudy/making-data-and-apis-easy) ![Picture of SEQTEK'S DEV TEAM](https://blog.seqtek.com/hs-fs/hubfs/Blog%20Imagines%20for%20Hubspot%20(1).png?width=50&name=Blog%20Imagines%20for%20Hubspot%20(1).png) [SEQTEK'S DEV TEAM](https://blog.seqtek.com/casestudy/author/seqteks-dev-team) Nov 15, 2022 1:21:00 PM Making Data and API'S Easy Problem: The company had significant tech debt from inexperienced...
