Business Application Development
1. Production Management System
Thailand is one of the countries where many Japanese manufacturing companies, especially automobile manufacturers, have advanced. Sunny Systems provides IT support to such manufacturing companies.
In addition to parts management and production planning, we offer a comprehensive application system that provides total support for manufacturing operations, including the supply chain from order receipt to shipment. We provide “tailor-made application systems” to meet your budget and requirements, if you find that commercial package systems are too expensive or do not match your business processes. We have a lot of experience in JAVA and .NET and C# development.
2. Sales Management System
Along with the production management system for the manufacturing industry, our sales management system has also been well received. We have created the application UI/UX with an emphasis on ease of use, such as displaying product information in a list, and selecting a target from the list to see the product details. In addition to product sales status, the systems can also include analysis functions such as sales by product and sales by customer. We also have a lot of experience in JAVA and .NET and C# production.
The data at the time of Quotation creation can be consistently used for entering purchase orders (POs) from customers, issuing POs to suppliers, issuing Invoices after delivery, and issuing Tax Invoices and Receipts. This not only improves working productivity by eliminating the need to re-enter the same data, but also prevents human input errors. It is also compatible with dot printers, so you can print on Invoice paper using carbon paper, reducing the number of times you have to sign.
3. Attendance and personnel management system
Customers who use our production management systems and sales management systems sometimes entrust us with systemization of their internal administrative tasks, such as attendance and personnel evaluations.
We can flexibly respond to your needs, from managing employee information, recording attendance, paid leave, and other attendance applications and approvals, to creating monthly attendance reports, and even recording personnel evaluations.
Offshore development, lab-based development
We offer offshore development services not only in Thailand but also from Japan. We propose Japanese SEs with the technology and experience to act as a bridge between you and the client (bridge SE), listening to your requirements and working with the local development team to ensure delivery. We can respond flexibly according to the characteristics of the project, such as commissioned development or lab-based development.
