Business System Consulting & Integration Services for Small & Medium Enterprises

Business System Consulting & Integration Services

Hello,

[View Vietnamese Version]

My name is Nghia Nguyen. I provide consulting and implementation services focused on SAP Business One, DMS (Distribution Management System), and various tools to support internal operations, reporting, and system integration – including Power BI, Microsoft 365, and custom-built applications.

I don’t aim to take on as many projects as possible. Instead, I focus on working closely with each business, reviewing existing systems, identifying real issues, and proposing solutions that are simple, effective, and easy to adopt for internal teams.


🎯 Experience & Technical Background

I’ve spent many years implementing SAP Business One and DMS solutions for businesses across different industries: manufacturing, distribution, retail, food production, and pharmaceuticals.

In most projects, I directly handle:

  • System configuration and business process alignment.

  • Custom report development and function enhancement.

  • Troubleshooting ERP issues and bridging gaps across departments.

  • Integrating SAP with systems such as CRM, HRM, e-invoicing, e-signature, banking, and POS.

Technically, I’ve worked extensively with:

  • SAP B1: Configuration, Crystal Reports, SQL, AddOn, DI API / Service Layer.

  • Integration: Building APIs and middleware to link SAP with third-party systems.

  • Application development: CRM, WMS, POS tools (.NET, Java, Windows Forms, Windows Service).

  • Reporting & analytics: Power BI, Excel, SQL Views for dashboards and management reporting.

I don't claim to be the top expert, but I understand system logic and how real businesses operate – and I can help make systems work better for you.
