For most newly established FDI companies in Vietnam, the first finance question is not “how” but “who”: build an in-house accounting team, or use outsourced accounting for FDI companies in Vietnam? The decision shapes operating cost, compliance quality and penalty exposure — because Vietnamese Accounting Standards (VAS) differ substantially from the IFRS framework your head office uses, and Vietnam’s tax filing calendar is denser than most of the region.
Why the accounting staffing question is uniquely hard for FDI companies
Three local particularities mean you cannot simply copy the staffing model from your home market:
- VAS is mandatory; IFRS is only a reference. Statutory books must be kept under VAS, in Vietnamese. An accountant fluent in IFRS but new to VAS can still misstate revenue recognition, accruals or foreign-exchange differences.
- The Accounting Law requires a Chief Accountant. The role demands a prescribed certificate — a position that is hard to recruit and retain at a reasonable salary, especially outside the major cities.
- Every report lives in two languages. The tax authority works in Vietnamese; your head office reads English. Missing either side means management information always arrives one beat late.
The true cost of an in-house accounting function
Many CFOs compare salaries only, yet the total cost of owning an accounting hire in Vietnam typically runs 35–45% above gross salary:
- A general accountant with FDI experience in Hanoi or Ho Chi Minh City commands a significant salary — and a properly certified Chief Accountant costs considerably more;
- Employer-side mandatory insurance adds roughly 21.5% on top of payroll;
- Accounting software, digital signatures, e-invoicing and annual tax-policy training all add up;
- The hardest cost to price: a resignation mid-finalisation season, taking the institutional memory of your books along with it.
What outsourced accounting for FDI companies should include
A proper outsourcing engagement goes well beyond “keeping the books for you”. The standard scope an FDI company should demand has four layers:
1. Monthly and quarterly accounting
Transaction recording, bank reconciliation, receivables and payables management, depreciation and prepaid-expense allocation — delivered with a bilingual management-reporting pack so the parent company sees the position in near real time.
2. VAS statutory financial statements
Year-end statutory financial statements prepared on the correct VAS templates, plus a VAS-to-IFRS conversion package for group consolidation. FDI financial statements are subject to mandatory independent audit, so the books must stay audit-ready all year — not “cleaned up” in the final month.
3. Tax filing and finalisation: VAT, CIT, PIT
Value Added Tax declared monthly or quarterly; Corporate Income Tax provisionally paid each quarter and finalised annually; Personal Income Tax withheld, declared and finalised for both Vietnamese and expatriate staff. Late filings can attract fines of tens of millions of dong per instance under the prevailing penalty regime — before late-payment interest is counted.
4. Representation during tax audits and inspections
The layer most often ignored in price comparisons. When the tax authority requests explanations, a professional provider prepares the file, sits across the table from the inspection team and defends the accounting treatments applied — instead of leaving a foreign director to improvise through an interpreter.
Quick comparison: in-house vs outsourced
| Criteria | In-house accounting | Outsourced accounting |
|---|---|---|
| Monthly cost | Salary + ~21.5% insurance + software + training | One bundled fee, typically far lower below ~50 headcount |
| Certified Chief Accountant | Separate hire or appointed service | Included in scope |
| Operational continuity | Interrupted by resignations | Backed by a team, not one person |
| Vietnamese–English reporting | Depends on the individual | Contractually committed |
| Direct internal control | High — same office | Via process and reporting cycles |
| Best fit | Large manufacturers, complex costing | Trading, services and office-based FDI under ~50 staff |
When an FDI company should hire in-house
Outsourcing is not the answer in every case. Consider building an internal team when transaction volume exceeds several thousand documents a month; when manufacturing operations involve complex cost accounting; or when the group requires consolidated close within the first 3–5 working days of the month. At that stage, the common model is hybrid: an internal team runs daily operations while an advisory firm provides tax review and represents the company before the authorities.
