Which accounting service company is the best? This is a question almost every business owner asks at least once when starting a new business, when an in-house accountant suddenly leaves, or after being subject to tax audits due to erroneous records. The problem is that the market has hundreds of companies claiming to be "reputable," while the consequences of a wrong choice don't appear immediately, but only become apparent during the tax audit period when the tax inspection team intervenes. This article systematizes the evaluation criteria according to the regulations of the Accounting Law, and compiles a list of the Top 10 accounting service companies currently trusted by the market to provide businesses with a basis for objective comparison.
Why is the question "which accounting service company is good?" always so difficult to answer accurately?
There is no official ranking that declares which accounting service company is best for every business, because "good" for a small business is completely different from "good" for a foreign direct investment (FDI) company with related-party transactions. Therefore, the first step is not to find a name, but to understand what legal conditions and professional capabilities you need to meet as a partner.
Three risks of choosing the wrong accounting service provider.
Firstly, there is the risk regarding the legal status of the service provider itself. According to Article 60 Accounting Law No. 88/2015/QH13Accounting services are a conditional business sector. A company wishing to operate legally must obtain a Certificate of Eligibility to conduct accounting services, employ practicing accountants under full-time employment contracts, and follow the procedures stipulated in Circular 297/2016/TT-BTC. Many small businesses in the market only possess ordinary business licenses and lack the qualifications to practice accounting services; therefore, the company hiring them ultimately bears the legal consequences.
Secondly, there is the risk of operational errors leading to tax arrears and penalties for late payment. Tax policies are constantly changing; by 2026, businesses with related-party transactions alone will have to update their policies immediately. Decree 255/2026/ND-CP Regarding the 30% EBITDA threshold for interest expense, an accounting service provider that fails to keep up with the new regulations will put clients at risk of having expenses disallowed, taxes collected retrospectively, and late payment interest charged.
Thirdly, there is a risk of operational disruption when the service provider lacks the capacity for long-term support. Abandoned accounting records and incomplete handovers when changing accounting firms are common situations for small companies lacking internal quality control processes.
The legal framework determines the reputation of an accounting service company.
To determine which accounting service company is good and qualified to entrust with its bookkeeping, businesses need to compare three original documents: the Accounting Law No. 88/2015/QH13 (conditions for practicing the profession in Articles 59 and 60), Circular 297/2016/TT-BTC (Issuing and managing Certificates of Eligibility for Accounting Services), and current tax decrees and circulars that the unit must be familiar with in order to provide accurate advice to each type of business. This provides an objective basis for comparison, instead of relying solely on advertising or subjective assessments.
6 criteria for evaluating which accounting service company is best for your business.
Once they understand the legal framework, businesses can use the following six criteria to quickly filter which accounting service company is good and suitable for their size.
Conditions for practicing accounting services
Require the provider to supply copies of the Certificate of Eligibility for Accounting Services and the Professional Registration Certificate of the assigned accountant. This is a minimum requirement and non-negotiable, as a provider that avoids supplying these documents is almost certainly not a safe choice.
Professional competence and ability to stay updated on new tax policies.
A reputable accounting firm must demonstrate the ability to keep up-to-date with legal regulations almost in real time, from value-added tax and corporate income tax to new regulations on related-party transactions.
Service scope and long-term partnership capabilities
Businesses should prioritize providers offering comprehensive services such as accounting, tax filing, financial statement preparation, tax settlement, related party transaction consulting, and support during audits. A company that only handles bookkeeping without a specialized tax consulting department will struggle to manage complex situations that arise throughout the year.
Commitment to responsibility, confidentiality, and compensation.
The service contract should clearly state the provider's responsibilities in the event of errors due to operational mistakes, along with a commitment to maintaining the confidentiality of the company's financial data.
Service costs are transparent and there are no hidden fees.
The price list should clearly show what is included in the package price and what additional charges apply (e.g., processing tax refund applications, providing explanations during audits). Prices that are too low compared to the general market often involve cutting back on qualified personnel, risking a decrease in service quality.
Real-life reviews from customers who have used the product.
Referencing feedback from customers in the same industry and of similar size will give you a perspective that closely matches your business's actual needs, instead of relying solely on general ranking articles. Businesses can also refer to additional resources. reputable tax accounting services company To compare the criteria before making a decision.

Why do businesses choose MAN when looking for a good accounting service company?
Looking solely at price lists, many companies on the market appear similar. The real difference only becomes apparent when a business encounters a complex situation, and this is when MAN's value becomes most evident.
Specialized expertise in related-party transactions. With Decree 255/2026/ND-CP recently coming into effect, the threshold for identifying related-party relationships has been clarified and expanded, bringing many businesses previously not subject to regulation now within its scope. MAN's team of accountants closely monitors each provision, from the calculation of net interest expense, the 30% EBITDA threshold, to the right to carry forward expenses for no more than 5 years, ensuring clients do not miss out on legal benefits and avoid common technical errors that lead to expenses being disallowed during audits.

Instead of waiting until the tax settlement period to review, we build a continuous monitoring system for our clients: a ledger tracking interest expense accruals for each year, early warnings when the business is at risk of exceeding the threshold, and advice on capital restructuring to sustainably reduce tax pressure.
The required documentation is essential when dealing with the tax authorities. All spreadsheets and conclusions regarding affiliation status are stored by MAN with specific references to legal provisions and audited financial statements.
We work together transparently and fulfill our contractual obligations. MAN provides complete accounting service business licenses, contracts clearly outlining the scope of responsibilities, and maintains direct communication channels with clients throughout the settlement process, ensuring that businesses are not left "alone" when inspection teams arrive.

Frequently Asked Questions about Which Accounting Service Company is Good?
Which accounting service company is best for a newly established business?
Newly established businesses should prioritize providers offering comprehensive service packages with clear costs, parallel support for initial legal procedures and periodic tax filing, and possessing all necessary certificates of eligibility to conduct accounting services in accordance with the Accounting Law.
What accounting firm should a business with related-party transactions choose?
Priority will be given to units with a dedicated team specializing in transfer pricing, possessing a thorough understanding of the regulations in Decree 255/2026/ND-CP, and capable of preparing documentation for determining transfer pricing and tracking the carry-forward of interest expense over multiple years.
How can you tell if an accounting service company is legally qualified to practice?
The applicant is required to provide a Certificate of Eligibility to Conduct Accounting Services issued by the Ministry of Finance and a Certificate of Professional Registration for the accountant in charge, as stipulated in Articles 59 and 60 of the Accounting Law No. 88/2015/QH13.
Should the cost of a full-service accounting package be as low as possible?
No. Unusually low prices often come with cuts to qualified personnel, increased risk of errors, and delays in updating to new regulations, resulting in significantly higher costs for back taxes and late payment penalties than the initial savings.
Should you change your accounting service provider in the middle of a fiscal year?
It is possible, but the former unit needs to hand over all books and documents, and the new unit needs to review all data before taking over to avoid disruptions or discrepancies in the data during settlement.
