What our customers say

Early testers of our AI Agentic system share their experience.
I just type 'bought 500kg steel from Hoa Phat, 15M VND' and the AI creates the full journal entry. I used to rely on my accountant for everything. Now I can input transactions myself.
Mr. Tai Le
Director
Since thuế khoán was abolished, I was worried about kê khai and e-invoices. Vietbooks handles TT 152 books automatically. I just enter what I buy and sell. The tax form 01/CNKD is generated with one click.
Mrs. Loan Nguyen
Hộ kinh doanh owner
I used to depend on my accountant for everything. Now I just type what I bought or sold, AI creates the entries. The Knowledge Agent explains regulations when I have questions.
Mr. Hieu Nguyen
Small Business Owner
The Analytics Agent showed me that our Q3 material costs rose 23% while revenue was flat. That insight led us to renegotiate supplier contracts. No other accounting software does this.
Mr. Cong Vo
CEO
The Entry Agent handles 80% of routine entries from XML invoices. I just review and approve. What took 3 hours now takes 30 minutes. The Knowledge Agent answers circular questions with article references in seconds.
Ms. Ngoc Le

AI & Agentic

1. What is Vietbooks Agentic?
Vietbooks Agentic is an AI-powered accounting add-on that automates your workflow using agentic AI. It includes three intelligent agents:
  • Entry Agent — automatically creates journal entries from descriptions and processes e-invoice XML files into ready-to-post entries
  • Knowledge Agent — looks up circulars and regulations, then delivers specific answers with references
  • Analytics Agent — builds financial reports from your data and combines them with real-time market research to deliver actionable business insights
The AI learns from your corrections, improving accuracy over time for your specific company.
2. How accurate is the AI? Can I trust it?
Vietbooks uses a human-in-the-loop approach: all AI-generated entries require your approval before posting. You can review and edit any AI draft before it becomes final. The agentic system tracks accuracy metrics and uses machine learning to learn from your corrections, continuously improving for your company's specific accounting patterns. No AI entry is ever posted without human verification.
3. Is my accounting data used to train AI or LLM models?
No. Your accounting data is never used to train AI models or LLMs. The AI agents use your data only within your account to answer questions and generate entry drafts. Correction data (your edits to AI-generated entries) is stored separately and used exclusively to improve AI accuracy for your company — it is never shared or used for general model training.

E-Invoice (Electronic Invoice)

4. What e-invoice providers does Vietbooks support?
Vietbooks integrates with Viettel SInvoice for issuing e-invoices directly from the software. For importing purchase invoices, Vietbooks can process XML e-invoices from any provider.
5. Can I issue e-invoices directly from Vietbooks?
Yes. With a Viettel SInvoice account, you can issue e-invoices directly from Vietbooks. The workflow supports: save as draft, issue individually, or batch issue up to 100 invoices at once. You need to register a SInvoice account with Viettel separately.
6. How does auto XML import work?
Upload XML e-invoice files (up to 50 at once). Vietbooks automatically reads all invoice fields and creates accounting entries, vendors, customers, and products. Smart mapping remembers your product and vendor classifications for faster processing next time.
7. Is Vietbooks compliant with current e-invoice regulations?
Yes. Vietbooks is fully compliant with Decree 123/2020/ND-CP, Decree 70/2025/ND-CP (effective June 2025), and Circular 32/2025/TT-BTC. The e-invoice XML format follows the standard defined by the General Department of Taxation.

Hộ kinh doanh & Business Owner Mode

8. What is Mode for Business Owners? Is it suitable for hộ kinh doanh?
Mode for Business Owners (Regular Mode) is a simplified interface for non-accountants, including hộ kinh doanh owners. Manage sales, purchases, customers, vendors, and products without accounting complexity. For HKD, Vietbooks fully supports TT 152/2025/TT-BTC with simplified books, tax declarations per TT 18/2026, and e-invoice issuance — all through this easy-to-use interface. Your accountant can use Accountant Mode on the same data.
9. Lump-sum tax (thuế khoán) is abolished. What must HKD do from 2026?
From 1/1/2026, all HKD must self-declare taxes (kê khai). Under Nghị Định 68/2026, HKD are classified into 4 revenue groups: Group 1 (≤500M — exempt, use book S1a-HKD), Group 2 (500M–3B — tax on revenue %, use S2a-HKD), Group 3 (3B–50B — quarterly + annual settlement, use S2b–S2e-HKD), Group 4 (>50B — monthly). Tax forms: 01/TKN-CNKD for Group 1, 01/CNKD + 02/CNKD-TNCN-QTT for Groups 2-4 (per TT 18/2026). E-invoices mandatory for revenue ≥ 1B VND/year. Vietbooks handles all of this automatically.
10. What books and tax forms does Vietbooks support for HKD?
Accounting books per TT 152/2025/TT-BTC (effective 1/1/2026, replacing TT 88/2021): S1a-HKD (revenue book for Group 1), S2a-HKD (revenue with tax for Group 2), S2b-HKD (revenue with VAT), S2c-HKD (revenue & expense detail), S2d-HKD (inventory detail), S2e-HKD (cash detail), S3a-HKD (other tax obligations). Tax declaration forms per TT 18/2026/TT-BTC: 01/TKN-CNKD (annual notification for Group 1), 01/CNKD (periodic VAT & PIT for Groups 2-4), 02/CNKD-TNCN-QTT (annual PIT settlement), 01/BK-STK (bank account notification). All auto-generated from your transaction data.
11. What are the VAT and PIT rates for hộ kinh doanh?
Under Nghị Định 68/2026, rates depend on industry: Distribution/supply of goods: VAT 1%, PIT 0.5%. Services, construction without materials: VAT 5%, PIT 2%. Property rental: VAT 5%, PIT 5%. Manufacturing, transport, construction with materials: VAT 3%, PIT 1.5%. Other activities: VAT 2%, PIT 1%. Vietbooks automatically applies the correct rates based on your registered industry categories.

Data security and safety

16. How is my data secured?
Your data security is our top priority. We take extensive measures to make sure that your data is 100% encrypted. These measures include:
  • Encryption at rest:
    • Your data is stored 100% encrypted on disk. This means that, any third party who gets a hold of the hard drive or a copy of the data but does not have the encryption key, still cannot read your data.
  • Encryption on the move:
    • When data is transmitted over the Internet, it is also encrypted with HTTPS. HTTPS is used by the world's top banks. This is the method protects your data from any third party on the Internet.
    • At our data center, when your data is transmitted among our own servers, they are also protected with TLS. This means that your data is also protected from anyone who can tap into the data centers network.
Last but not least, Vietbooks's cloud service provider Amazon AWS follows strictly international security management standard that specifies security management best practices and comprehensive security controls. Amazon AWS has certifications for compliance with ISO/IEC 27001:2013, 27017:2015, and 27018:2014.
17. How is my data safe?
Besides security, safety of your data is also of utmost important to us. To make sure your data is safe, we continuously replicate and store your data in an extensively careful manner:
  • At Amazon AWS, one of the most reputable datacenters.
  • On different time scales: in real time and every set hour.
In total, your data is replicated 20 times. In summary, you will never have to worry about the safety of your data on Vietbooks.
18. What happen to my data after I stop using the service?
You can delete all accounting data that you created by yourself before you stop using the service. If you do not delete them, we will retain your data only up to 30 days and might delete them permanently. You can also request us to delete your accounting data immediately.
19. What is data encryption at rest?
When your data is stored on a hard drive, it is normally not encrypted. Therefore, whoever gets a hold of your physical hard drive can read your data by simply plugging the hard drive into a different system. Encryption at rest means that data is stored as encrypted files, and from the perspective of the file system, they are just binary scrambled data. Using this method, any third party who gets a hold of the hard drive or a copy of the data but does not have the encryption key, still cannot read your data.
20. What is HTTPS? How does Vietbooks use HTTPS?
When the web just started, HTTP protocol is the default protocol. Information sent using the protocol is plaintext and anyone who can capture packets can read the data. To protect sensitive information sent over the Internet, an extension of HTTTP was proposed, called HTTP Secure (HTTPS). In this version, HTTP data is encrypted (using TLS protocol) before sending, thus data is protected from eavesdropping. HTTPS is widely used today by many reputable websites including the world's top banks.

To protect our customers, Vietbooks does not provide service over HTTP and only provide service over HTTPS. HTTPS is provided with strong 128-bit key, TLS 1.3, and Vietbooks' TLS/SSL certificate is provided by Let's Encrypt

Service availability

21. What is the level of availability of Vietbooks?
Vietbooks follows industry best practices to provide you with highly available (HA) services:
  • Vietbooks runs on Amazon Web Services (AWS), one of the most modern and largest cloud service providers in the world. Inherently, there are redundancies for services provided on a cloud platform. In particular, AWS has committed at least 99.99% server uptime every month.
  • Moreover, we set up additional redundancies for every component used to provide the service: from app servers, databases, and load balancers to DNS servers. This makes sure that any software error or hardware failure of any single component will not disrupt our service.
As a result, you can be assured that Vietbooks will be available to accompany you anytime and anywhere.
22. Will Vietbooks be slow when Internet optic cables have problems?
Minimal. Vietbooks optimizes data transfer so that it operates well under degraded international connections.
23. Can I access Vietbooks without Internet?
No, you need an Internet connection to use Vietbooks.
24. What accounting circulars and regulations does Vietbooks support?
Vietbooks fully supports Vietnamese accounting circulars 99 (200), 133, and TT 152/2025 for hộ kinh doanh. The software automatically applies the correct chart of accounts, report templates, and compliance rules based on your selected circular.
