🌏 For FDI subsidiaries in Vietnam · 5 languages · TT 200/TT 78
Accounting + e-invoicing for foreign companies in Vietnam
One system for your HQ in Tokyo / Seoul / Singapore and your accounting team in Hanoi / HCMC. Bilingual templates, multi-currency, English support, full Vietnamese-VAS compliance.
Why FDI subsidiaries pick est-invoice
Four reasons Japanese, Korean, Singaporean, and US parent companies specify est-invoice for their Vietnam subsidiaries.
100% Vietnamese-VAS compliant
TT 200 (accounting standards), TT 78 (e-invoicing), TT 32 (electronic books), Accounting Law Article 41 (10-year retention). Big-4 audited for three FDI customers.
Bilingual templates out of the box
Invoices, contracts, quotes printed side-by-side in Vietnamese + your HQ language (EN/JA/KO/ZH). HQ can read them; Vietnam tax authority accepts them.
Multi-currency + State Bank FX
VND/JPY/USD/SGD/CNY/KRW/EUR. FX rates auto-fetched from the State Bank of Vietnam (NHNN) — not user-entered rates. Audit log records the rate at transaction time.
English support in real time
Email + chat in English (08:00–22:00 ICT). Onboarding via Zoom with a translator on call. Docs in 4 languages.
Bilingual document templates — ready to use
Every document prints in two languages side-by-side. HQ overseas can read it; Vietnamese accountants stay compliant.
- ✓Bilingual VAT invoices (TT 78 standard, GDT-verified)
- ✓Bilingual contracts + addenda with parallel-column layout (Vietnamese left, foreign right)
- ✓Quotes, purchase orders, acceptance reports — all have bilingual templates
- ✓P&L / Balance Sheet exported in English for HQ; in Vietnamese for tax authority — same data, two outputs
Multi-currency + State Bank FX rates
FDI subsidiaries deal in multiple currencies daily. est-invoice handles foreign currency transactions and records FX correctly by Vietnamese law.
- ●FX rates from the State Bank of Vietnam (sbv.gov.vn) — automatic, real-time, audit-proof
- ●Captures the rate at transaction time (not the current rate), as required by VAS
- ●Period-end FX revaluation — automatic recognition of exchange-rate gain/loss
- ●Export reports in any of 7 currencies — no manual translation needed
