At S4 Consulting, We Believe Data Drives Profitability.
We partner with Vietnamese businesses on their digital transformation journey – helping them make data-driven decisions and operate more efficiently through modern ERP platforms such as Acumatica Cloud ERP and Oracle NetSuite.
We believe that behind every number lies an opportunity to improve. When a company truly understands its data, it uncovers new paths to growth, efficiency, and cost optimization – often in places that once seemed invisible.
Our Mission
We founded S4 Consulting with a clear purpose — to help businesses in Vietnam and across Asia operate with clarity, agility, and control through modern ERP platforms such as Acumatica Cloud ERP and Oracle NetSuite.
We’ve seen too many organizations struggle with fragmented systems and delayed insights. That’s why we focus on helping our clients build a real-time financial management model where every figure — from revenue and cost to cash flow and operational performance — is transparent and actionable.
Through this, we enable business leaders to:
- Make data-driven decisions based on accurate, real-time insights rather than assumptions.
- Reduce operational waste and manual work through process standardization and automation.
- Build a culture of accountability and efficiency that scales with growth.
