Pioneering The 2-Tier ERP Model In Vietnam.
S4 is an advisory firm specializing in optimizing the 2-Tier ERP model, and also directly implements Acumatica at Tier 2 for subsidiaries. This is a deeply vertical-specific solution, where the Unlimited User License policy is especially well suited to operationally heavy subsidiaries.
Three Success Factors For Enterprise
ERP Architecture
An effective 2-Tier ERP architecture needs all three layers working in sync – it’s not simply about choosing two pieces of software.

High-Volume Transaction Processing
The Tier 1 ERP system (SAP S/4HANA, Oracle Fusion, Oracle EBS) processes millions of transactions and acts as the single source of truth for the entire group – consolidating finance and centralizing control at the highest level.

Flexibility And Cost Optimization
Specialized subsidiaries in Construction, Manufacturing, Logistics, F&B chains, and Distribution need a system flexible enough to closely track real operations, at an optimized cost even with a large user base – while still being able to consolidate financial reporting up to the group.

A Powerful Integration Backbone
The two system tiers need a connection backbone strong enough to synchronize data in real time – avoiding discrepancies between levels and minimizing the risk of manual reconciliation across multiple systems.
How Does S4 Consulting Solve These Three Challenges?
Acumatica – The Perfect Choice For Tier 2
Thanks to its deeply vertical-specific editions (construction, manufacturing, distribution, F&B…) and its Unlimited User License policy – exactly what an operationally heavy subsidiary needs: flexibility and cost optimization even with many users.
Mastery Of Integration Technology
S4’s own No-Code/Low-Code Integration Middleware platform connects Tier 1 and Tier 2 with real-time synchronization – exactly the integration backbone a 2-Tier architecture needs to run smoothly.
Deep Expertise In Tier 1 Systems
A firm command of the data structures and financial-consolidation logic of Tier 1 platforms such as Oracle (Fusion, EBS) and SAP (S/4HANA) – ensuring data from Tier 2 connects accurately up to the group’s standards.
