Bookkeeping in Vietnam: What the Law Actually Requires
Short answer: every company operating in Vietnam must keep its books in Vietnamese, in Vietnamese dong, under Vietnamese Accounting Standards (VAS), and must produce annual financial statements within 90 days of its financial year end. Foreign-invested enterprises must also have those statements audited by an independent auditor before filing. Outsourced accounting services in Vietnam exist to carry that obligation for you — not to replace your finance function, but to make it compliant.
The Statutory Baseline
| Requirement | What it means in practice | Legal basis |
|---|---|---|
| Accounting language and currency | Books in Vietnamese and in VND; a foreign currency may be used as the accounting currency only where the conditions are met | Law on Accounting 88/2015/QH13 |
| Accounting framework | Vietnamese Accounting Standards and the applicable corporate accounting regime | Law on Accounting 88/2015/QH13 |
| Annual financial statements | Prepared and filed within 90 days of financial year end | Law on Accounting 88/2015/QH13 |
| Independent audit for FDI | Annual statutory audit before the statements are filed | Decree 17/2012/ND-CP |
| Chief accountant | A qualified chief accountant, in-house or engaged as a service | Law on Accounting 88/2015/QH13 |
| Document retention | Accounting records retained for the statutory period and producible on inspection | Law on Accounting 88/2015/QH13 |
A company that reports to a foreign parent usually needs two sets of numbers: the statutory VAS set that is filed in Vietnam, and the group set under IFRS or the parent’s local GAAP. Producing one from the other is a conversion exercise, and it is where most reporting errors originate.
What Full-Service Accounting Covers
Monthly and quarterly cycle
- Recording of purchases, sales, cash, bank and payroll transactions into the VAS chart of accounts
- Input and output VAT reconciliation against e-invoices issued and received
- Payroll calculation, personal income tax withholding and social insurance declarations
- Periodic VAT, PIT and provisional CIT declarations filed on the statutory dates
- Monthly management reporting in the format your head office needs
Annual cycle
- Year-end closing entries, accruals, provisions and fixed-asset roll-forward
- Statutory financial statements under VAS
- CIT and PIT annual finalisation
- Audit support: preparing the working paper file and answering auditor queries
- Filing to the tax authority, the statistics office and the licensing authority
Where an engagement usually starts
Rarely from a clean sheet. Most companies come to us with prior-year books that need review before the current year can be closed: unreconciled balances, VAT that does not tie to the e-invoice system, payroll that does not tie to the social insurance filings, or fixed assets recorded without depreciation schedules. That review is the first deliverable, not an add-on.
Outsourced Accounting vs an In-House Team
| In-house accountant | Outsourced accounting service | |
|---|---|---|
| Coverage when the person leaves | Work stops; handover risk is high | Continuity is contractual |
| Regulatory updates | Depends on that individual keeping current | Applied across the whole client book |
| Segregation of duties | Difficult with one or two people | Preparer and reviewer are different people |
| Chief accountant qualification | Must be hired separately | Can be provided as part of the engagement |
| Scaling with transaction volume | Requires new headcount | Scope is adjusted |
| Best suited to | Companies with high daily transaction volume and an internal finance lead | SMEs, FDI subsidiaries, representative offices, companies in the start-up phase |
The honest answer is that the two are not mutually exclusive. A common arrangement is an in-house accounts clerk handling daily entries, with the statutory reporting, chief accountant role and tax filings outsourced.
Who This Service Is For
- FDI subsidiaries that need VAS-compliant statutory books and a parallel reporting pack for the parent
- Newly licensed companies that must have an accounting system in place from the first month of operation
- SMEs whose accountant has left, or whose books have fallen behind
- Companies preparing for audit, due diligence or a bank facility, where the books must withstand outside review
- Dormant companies that still carry filing obligations
Accounting outsourcing: which companies use it
Accounting outsourcing means the whole accounting function is delivered for you — documents, books, declarations and statements — rather than one person being placed in your office. In practice the companies that gain most are:
| Company profile | The problem it starts with | What outsourcing changes |
|---|---|---|
| Newly incorporated company | No finance staff; the first filing obligations are unclear | The compliance calendar starts correctly from the first period |
| Small and medium enterprise | One accountant doing every task, with no review | Preparer and reviewer separated at a lower total cost |
| Foreign-invested enterprise | Group reporting in English, statutory filing in Vietnamese | One team producing both from the same ledger |
| Representative office | Low volume but the full set of compliance obligations | Compliance maintained without a dedicated hire |
| Company preparing for financing or sale | Records that will not survive due diligence | Books standardised before the buyer or the bank arrives |
Where prior-year records are incomplete, a review of the historic books usually runs before the recurring service starts, so the opening balances the new cycle depends on are known to be sound.
If what you need is a person rather than the function — a chief accountant or an accounting team working under your own processes — see accounting staff outsourcing instead.
Frequently Asked Questions
Can bookkeeping in Vietnam be done entirely in English?
The statutory books and filings must be in Vietnamese. The reporting you receive, the working papers and all correspondence can be in English, and for FDI clients they normally are.
We are behind by several months. Can you still take this on?
Yes. Catching up prior periods is a defined piece of work with its own scope: we reconstruct the periods, quantify any late-filing exposure, and then move you onto the normal monthly cycle.
Do you provide the chief accountant?
Yes, as a separate engagement where the company does not employ a qualified chief accountant directly.
Which accounting software do you work with?
We work in the client’s system where one exists, and provide one where it does not. The software matters far less than whether the underlying records reconcile.
Who owns the data?
You do. Books, working papers and supporting files are your property and are handed over in full at the end of any engagement.
