Executive Summary
Saigon South International School (SSIS) is a leading international K-12 school in Ho Chi Minh City, Vietnam, serving approximately 1,600 students with more than 400 faculty and staff.
As the school expanded, its administrative environment became increasingly complex. Tuition structures varied by grade level and student circumstances, procurement required multiple approval layers, staff development budgets needed individual tracking, and finance teams relied heavily on spreadsheets and manual coordination.
SSIS needed more than a new software system, it needed a digital foundation capable of connecting these processes without disrupting established school operations.
Working with A1 Consulting - a brand from AHT Tech’s ecosystem that specializes in ERP solutions streamlining operations, automation, and digital transformation for sustained growth for businesses across Vietnam, Malaysia and Southeast Asia; SSIS implemented Odoo through a phased transformation approach. The project connected student information with tuition workflows, digitized internal approvals and procurement, and established a centralized platform for approximately 270 users.
The result was faster financial processing, improved operational visibility, reduced manual administration, and a scalable ERP foundation that can continue evolving with the school.

The Business Context
Running an international school involves significantly more operational complexity than managing student records alone.
Behind the academic environment, SSIS manages tuition billing, family-specific fee structures, procurement, staff expenses, professional development budgets, internal approvals, and financial administration.
As the school grew, many of these processes became more difficult to coordinate.
Student information and financial workflows did not always move through the same system. Staff relied on spreadsheets and email for parts of internal administration. Procurement required multiple levels of review, while the finance team had to manage increasingly complex tuition scenarios across a large student population.
Each process could still function independently.
The real challenge was the effort required to keep them working together.
SSIS therefore needed an ERP foundation that could connect critical administrative workflows while remaining flexible enough to coexist with existing systems and operating practices.

The Challenges
1. Fragmented Student and Financial Data
Student enrollment data and tuition processes were not fully connected. Finance teams needed accurate information about individual students before invoices could be prepared, but fragmented data flows created additional administrative steps.
Business impact: Repeated manual work increased the time required to prepare tuition invoices, particularly during high-volume billing periods.
2. Complex Tuition and Fee Structures
International school billing is rarely based on a single standard fee. SSIS manages different tuition structures across grade levels as well as mandatory charges, optional services, and family-specific circumstances.
Managing these variables manually increased operational complexity.
Business impact: The finance team faced greater dependence on manual calculations and reconciliation, increasing workload and making large-scale invoice preparation time-consuming.
3. High-Volume Procurement with Multiple Approval Levels
Preparing for academic operations can involve hundreds of purchasing requirements. At the same time, SSIS needed to maintain clear financial controls and ensure appropriate authorization across multiple management levels.
Business impact: Without structured workflows, maintaining governance could also create significant administrative overhead and slow down purchasing decisions.
4. Manual Employee and Professional Development Administration
With more than 400 faculty and staff, SSIS also needed to manage employee expenses and professional development funding. Requests, supporting documents, available budgets, and approvals all had to be tracked accurately.
Business impact: Fragmented email and document-based processes made it harder for employees and managers to maintain consistent visibility over request status and remaining budgets.
The Solutions
A Phased ERP Transformation Built Around Operational Priorities
Rather than replacing every administrative process at once, SSIS and A1 Consulting (AHT Tech) adopted a phased ERP implementation strategy.
The transformation focused first on workflows where integration and automation could create the clearest operational value. This allowed the school to modernize core processes progressively while reducing the risks associated with a large-scale, one-time system rollout.
The implementation followed four main priorities.
-
Connect Student Information with Financial Workflows
One of the priorities was creating a more direct connection between student information and tuition administration.
SSIS's student information environment was integrated with Odoo so relevant enrollment data could flow into downstream financial processes. Instead of requiring finance teams to repeatedly recreate or reconcile student information, the ERP could use synchronized data to support quotation and invoicing workflows.
What changed
Student information became part of a connected process:
Student Records → Odoo → Tuition Configuration → Invoice Generation
This reduced duplicate administrative work and created a more consistent foundation for billing.
-
Configure Odoo for Complex Tuition Scenarios
The ERP environment was configured to support SSIS's different tuition structures and associated charges.
Mandatory fees, optional services, and student-specific conditions could be handled within connected workflows rather than managed across independent spreadsheets.
The objective was not simply to automate invoice creation.
It was to create a repeatable financial process that could handle operational complexity at scale.
-
Digitize Procurement and Internal Approvals
SSIS also introduced structured approval workflows for procurement.
Requests could move through predefined authorization levels based on the school's governance requirements.
For larger purchasing cycles, related requirements could be consolidated rather than forcing senior management to review large numbers of isolated line items individually.
This helped maintain financial control while reducing unnecessary approval workload.
-
Bring Employee Requests and Expenses Into a Shared Workflow
Professional development and employee-related processes were also moved into Odoo.
Employees could submit requests, attach supporting documentation, review available budgets, and track approval status through the system.
Managers could review and approve requests digitally, including through mobile access.
The result was a clearer workflow for both employees and administrators, with requests, approvals, and associated expenses managed within a shared environment.
The Impact
Grade-Level Invoice Processing Reduced from 2 Hours to 10 Minutes.
The most visible improvement came from tuition invoicing.
- Before - Generating invoices for one grade level could take approximately: 2 hours
- After- Following implementation, the same process could be completed in approximately: 10 minutes
This represents a substantial reduction in repetitive administrative work during billing periods.
For the finance team, the value was not simply faster invoice generation. It reduced the amount of time employees needed to spend preparing routine transactions and allowed greater focus on exceptions, reconciliation, and other higher-value financial activities.
Average Collection Cycle Shortened by 25%
SSIS also introduced dynamic QR-code payment capabilities as part of its payment workflow. The school reported that its average collection cycle improved from: 16 days → 12 days
That represents a: 25% reduction in average collection time
The improvement supported both financial operations and the payment experience for families.
Greater Visibility Across Administrative Workflows
Processes that previously relied more heavily on manual coordination could now operate through connected workflows.
- Student information could feed into financial processes.
- Employee requests could move into approvals and expenses.
- Procurement could follow predefined authorization structures.
Management gained clearer visibility without requiring teams to manually consolidate information across multiple spreadsheets and email threads.
Less Administrative Friction Across 270 ERP Users
Odoo now supports approximately 270 users across SSIS. At this scale, even small reductions in repetitive tasks can create meaningful operational gains.
By centralizing key workflows, the school reduced the amount of manual coordination required between employees, managers, and administrative teams. This helped move the organization from process-by-process digitization toward a more connected operating environment.
From Process Automation to a Scalable Operating Foundation
The immediate benefits of the SSIS transformation are measurable.
- Invoice preparation became dramatically faster.
- Payment collection cycles shortened.
- Procurement and approval workflows became more structured.
But the longer-term value goes beyond individual KPIs. SSIS now has an ERP foundation that connects multiple administrative processes while remaining flexible enough to evolve alongside the school's needs.
Instead of rebuilding workflows every time operations change, the school can continue extending and optimizing a shared platform. This is particularly important for complex organizations where transformation cannot realistically happen all at once.
A phased approach allowed SSIS to modernize high-impact processes first, validate the operating model, and expand from a stable foundation.
What the SSIS Case Shows About Enterprise Transformation
Digital transformation is rarely successful because an organization simply installs a new platform. Value comes from how technology connects existing data, people, workflows, and decision-making.
For SSIS, the objective was not to replace spreadsheets for the sake of modernization. It was to reduce the operational effort required to manage increasingly complex administrative processes.
A well-designed ERP transformation should not force an organization to choose between operational control and efficiency. It should create a foundation where both can improve together.
Through a phased implementation, integration with existing systems, and structured workflow design, SSIS moved toward a more scalable and data-connected operating model while maintaining the flexibility required by a dynamic international school environment.
