Web & Business System Development
We start by deeply understanding your business processes before designing and building. One team supports you end-to-end, from requirements definition through ongoing operations and maintenance.
Facing challenges like these?
- We want to turn processes still run on Excel or paper into a proper system.
- An aging legacy system and rising maintenance costs have become a real problem.
- We handed development to a vendor, but the result drifted from our actual business requirements and ended up unused.
- We want to untangle and unify workflows that span multiple departments.
The VIETIS Approach
We start by digging deep into your workflows
We hold repeated interviews with front-line staff to understand how work actually gets done before moving into requirements definition — an essential step for delivering a system people actually use.
End-to-end, from requirements to operations
The same team handles design, development, testing, release, and ongoing operations and maintenance, so no information is lost in handoffs.
AI-driven development that balances speed and quality
We fold AI into our development process and combine it with a deep track record and expertise to reliably deliver high-quality systems.
Scope of Work
We cover everything from new business-system development to replacement projects and feature expansion.
Internal business systems
Design and development of systems that streamline operations — order management, inventory management, attendance management, expense reimbursement, and more.
Core system integration and modernization
Replacement of aging core systems and construction of integration APIs with ERP platforms, including migration design for existing data.
E-commerce systems and customer management
E-commerce platform builds and systems that support customer touchpoints, including membership management, points management, and CRM integration.
API development and system integration
Design and development of integration APIs between existing systems, including SaaS integrations and migration toward microservices.
Admin panels and dashboards
Admin panels built as a foundation for KPI visualization and data analysis, including BI tool integration and custom dashboard development.
Security and quality assurance
Process management based on CMMI Level 3 and ISO 27001, covering everything from security requirements design through vulnerability response.
Development Process
Starting from a solid understanding of your business, the same team carries the project through five well-defined phases.
-
01
Business interviews and requirements definition
We conduct repeated interviews with front-line staff to visualize workflows and produce a clear requirements document.
-
02
Basic and detailed design
We carry out screen design, database design, and API design, while also defining the approach for integration with existing systems.
-
03
Development and code review
We develop using an agile or waterfall approach, sharing progress along the way, and use AI to accelerate development speed.
-
04
Testing and user acceptance
We run unit, integration, and system testing, and also support user acceptance testing (UAT).
-
05
Release and operations
After go-live, we continue to provide system monitoring, incident response, and ongoing feature improvements.
