Tax, e-invoicing, data-protection and AI rules that shape an ERP, billing system or AI agent in Vietnam. Last reviewed October 2026.

Indirect taxVAT, standard rate 10% (8% on many goods and services until 31 Dec 2026)Resolution 204/2025/QH15 and Decree 174/2025 cut the 10% rate to 8% from 1 July 2025 to 31 December 2026 for most goods and services, now including IT and logistics. Telecoms, finance, banking, insurance, real estate, mining and excise goods are excluded.
E-invoicingMandatory · Tax-authority e-invoice (Decree 123/2020 as amended by Decree 70/2025)All businesses have had to issue e-invoices registered with the tax authority since July 2022. Decree 70/2025 and Circular 32/2025 (effective 1 June 2025) widened scope and tightened timing, content and correction rules, including cash-register-generated e-invoices for many B2C sellers.
Data protectionLaw on Personal Data Protection No. 91/2025/QH15Effective 1 January 2026, replacing Decree 13/2023, it requires data protection officers, impact assessments for processing and cross-border transfers, and sets administrative fines and criminal liability, so SaaS vendors handling Vietnamese users' data need documented assessments.

05 — FAQ

Custom software in Vietnam: common questions

Do you work with businesses in Vietnam?

Yes. Flip Retail is based in Jaipur, India, and works with Vietnam businesses remotely. We have no office in Vietnam; discovery happens on video calls, you get working software every two weeks, and the engineers who write the code are on the calls.

Can a custom ERP handle VAT and e-invoicing in Vietnam?

Yes. Invoicing is built for Vietnam's VAT (standard rate 10%). All businesses have had to issue e-invoices registered with the tax authority since July 2022. Decree 70/2025 and Circular 32/2025 (effective 1 June 2025) widened scope and tightened timing, content and correction rules, including cash-register-generated e-invoices for many B2C sellers. A custom ERP connects to the tax-authority e-invoice system through its official API or an accredited provider, and we confirm the current requirements in discovery.

How do you handle PDPL?

Effective 1 January 2026, replacing Decree 13/2023, it requires data protection officers, impact assessments for processing and cross-border transfers, and sets administrative fines and criminal liability, so SaaS vendors handling Vietnamese users' data need documented assessments. You choose where the system is hosted, access is role-based, and we work on test or masked data during development wherever possible.

Can you migrate us from MISA, Fast Accounting or Bravo?

Yes. Masters, ledgers, stock items and opening balances move across and are reconciled with your accountant before cutover, ideally at a year-end or quarter-end.

Are there AI rules we need to follow in Vietnam?

Vietnam's Law on Artificial Intelligence (No. 134/2025/QH15) took effect on 1 March 2026 with a risk-based framework, implemented by Decree 142/2026 (from 1 May 2026) and a government list of high-risk AI systems. We design AI agents with logging, human oversight and clear disclosure from the start, which covers most current requirements.
