Demo video: Vietnam Chart of Accounts - Circular 99 and 133
Stop struggling with Odoo's default Vietnam chart of accounts. This module replaces and upgrades the built-in l10n_vn with a production-ready Chart of Accounts that actually follows the latest regulations — Circular 99/2025/TT-BTC (for enterprises of all sizes) and Circular 133/2016/TT-BTC (for SMEs). It auto-installs on top of l10n_vn so you get the right COA from day one, with no manual data entry.
The standard Odoo l10n_vn module provides a basic Vietnamese Chart of Accounts, but its implementation has significant problems for actual use by Vietnamese accountants:
- Account codes are zero-padded to 4 digits (e.g. 511 becomes 5110), which doesn't match the codes accountants work with daily.
- No Circular 133 option for SMEs — only one chart is available.
- Import/export tax setup lacks the per-rate breakdown Vietnamese customs requires.
This module fixes these issues and provides two production-ready Charts of Accounts:
- Circular 99/2025/TT-BTC — 202 accounts with correct variable-length codes (3 to 5 digits), for enterprises of all sizes.
- Circular 133/2016/TT-BTC — 124 accounts for small and medium enterprises.
Both charts are selectable per company, so a single Odoo database can serve entities of different sizes.
What You Get
Correct Chart of Accounts
- Variable-length account codes matching the official circulars (111, 131, 6352, not 1110, 1310, 6352).
- Full Vietnamese and English account names from the official text.
- Account tags mapped to each account for Vietnamese financial report grouping.
- Automatic alignment when installed on a database already using base l10n_vn.
Tax Configuration
- Per-rate import duty taxes (0%, 5%, 10%) instead of a single flat rate.
- Export duty and VAT exemption taxes pre-configured.
- Tax report lines adjusted to match the Vietnamese VAT declaration structure.
Vietnamese Report Templates
- Payment receipt layouts following Template 01-TT (receipts) and 02-TT (payments).
- Journal entry report in the standard Vietnamese format.
- Report headers and footers with circular reference (TT99 or TT133) per company.
Safe Upgrade Path
- Installing on a database with existing l10n_vn data automatically renames padded account codes, replaces obsolete account references, and deprecates removed accounts — no manual cleanup needed.
- Existing journal entries and configurations are preserved.
Who Is This For?
- Any business operating in Vietnam that uses Odoo for accounting — this module brings Odoo's default Vietnam localization up to current regulatory standards.
- Odoo implementers and consultants deploying for Vietnamese clients who need a correct COA without hours of manual setup.
- Accountants who need Vietnamese-standard printed vouchers (Phiếu thu/chi) from Odoo.
