Your Financial Governance Expert. In Hanoi. On Your Team.
One Plus One has partnered with a senior Internal Audit and Finance professional with over 20 years of hands-on experience inside Vietnam’s most complex corporate environments — from Sacombank’s risk control operations to the boardrooms of Bach Viet Group, a multi-entity listed conglomerate spanning real estate, education, manufacturing, and FMCG.
This is not advisory from a distance. We embed directly into your operations, understand your actual exposure — financial, compliance, and operational — and deliver controls that work in the Vietnamese context while meeting the standards your international stakeholders, auditors, and investors expect.
Whether you need a focused one-off review or a fully outsourced Internal Audit function reporting to your board, we operate as an extension of your own team.
Senior expertise, no overhead, on the ground.
What makes this different
- Bilingual Vietnamese & English — no interpretation layer between you and your operations
- Native understanding of Vietnamese regulatory and business environment
- COSO-aligned Internal Control System design and implementation
- CIA-certified (IIA USA) — the global standard for internal audit
- Lean Six Sigma Green Belt — we improve processes, not just report on them
- Board-level communication experience with listed and public companies
- Full-scope coverage: financial audit, compliance, procurement, M&A, risk registers
What We Do
A complete financial governance service — six core capabilities, delivered by one senior consultant who knows your business, not a rotating team of juniors.
Internal Audit
Annual audit plans, quarterly and year-end financial statement audits, compliance reviews across all business units. We run the full cycle and report findings to management or your board.
Internal Control System Design
We build your ICS from scratch or strengthen what you already have — control environment, control activities, monitoring mechanisms, all aligned to COSO. Then we stay to make sure it works.
Risk Assessment & Registers
Structured risk mapping across your entity or group, compiled into a living enterprise risk register. Periodic review sessions keep it current — not a document that sits in a drawer.
Procurement & Tendering Governance
Vendor qualification frameworks, tender committee management, contract review, and spend controls. Proper procurement governance without slowing your operations down.
M&A Due Diligence
Financial and operational due diligence on Vietnamese acquisition targets. We look inside what others miss — control quality, compliance posture, real risk exposure, governance gaps.
Governance Documentation
Full policy, procedure, and process map libraries. Regulatory compliance monitoring. Investor disclosure management for listed or public companies. The infrastructure that makes governance real.
How We Work — No Black Boxes
Every engagement follows a clear, transparent sequence. You know exactly what we’re doing and why at every step.
Diagnostic & Scope Definition
We start by listening. A structured intake session maps your business, your risk exposure, and what’s keeping you up at night. We define scope and deliverables before any work begins — nothing vague, nothing open-ended.
On-Site Assessment
We go inside the operation. Document reviews, process walkthroughs, interviews with key personnel, transaction testing. We look at what actually happens — not what the manual says should happen.
Findings & Risk Register
Every finding is rated by severity, root-cause-analysed, and matched to a practical recommendation. We produce a risk register and prioritised action list — clear enough for a board presentation, specific enough for operations to act on immediately.
Controls Design & Implementation
We don’t drop a report and disappear. We help design the control activities, build the policy and procedure library, and support your team through implementation — until the controls are actually working, not just documented.
Training & Knowledge Transfer
We train your staff on ICS, COSO frameworks, risk management, and compliance — not generic awareness sessions, but targeted, practical training built around your own systems and processes.
Ongoing Monitoring & Board Reporting
For clients who want continuous coverage, we run periodic audit cycles, maintain the risk register, and report directly to your leadership or board. Your permanent internal audit function, at a fraction of the cost.
We don't work for your company. We become part of it.
The same philosophy that runs through every One Plus One service applies here: assigned consultant, full availability, total transparency.
Experience
20+ years of audit and controls work inside Vietnamese banking, real estate groups, listed companies, and manufacturing. Not advisory from abroad — expertise built from the inside, on the ground.
- Sacombank — 13 years banking audit & risk
- Bach Viet Group — 7 years group-level audit
- Listed & public company experience
Total Transparency
No fine print. No surprises. No softened findings to keep things comfortable. You’ll always get a direct, honest assessment of your control environment — and a practical path forward.
- Plain-language board reports
- Root-cause analysis, not just symptoms
- Constant communication throughout
Support
One dedicated senior consultant assigned to your engagement. Not a rotating team. Not junior staff. The person who assesses your controls is the same person who designs and monitors them.
- Assigned senior consultant
- Full availability during engagement
- Bilingual — Vietnamese & English
