TOP 5 highest rated electronic invoice software

I. Overview of Electronic Invoices

1.1. What is an electronic invoice? Common types of electronic invoices

Electronic invoices (E-invoices) are an inevitable solution in the digital age, encouraged by the Government and tax authorities to completely replace traditional paper invoices. In essence, E-invoices are a collection of electronic data messages about the sale of goods and provision of services, created, created, sent and stored by electronic means.

In Vietnam, legal regulations on electronic invoices have been standardized and continuously updated. The main legal basis is stipulated in Decree No. 123/2020/ND-CP and Decree 70/2025/ND-CP (replacing some articles of Decree 123). Most recently, Circular 32/2025/TT-BTC has taken effect since June 1, 2025, providing detailed instructions on the process of creating, managing and using electronic invoices, especially encouraging the use of electronic invoices generated from cash registers.

Based on these regulations, E-invoices in Vietnam are divided into three main types:

• Invoice with tax authority code: This is the type of invoice that is given an authentication code by the tax authority before the business sends it to the buyer. This type is suitable for small and medium-sized enterprises, or newly established businesses that do not have much experience in tax, helping to reduce the risk of errors due to inspection by the tax authority.

• Invoices without tax authority codes: For large enterprises with strong information technology systems and low tax risks. Enterprises self-issue invoices without waiting for codes, helping to save time and optimize processing speed.

• Cash Register Invoice: This special type of invoice is automatically generated from the cash register and has a direct data connection with the tax authority. It is ideal for retail business models, supermarkets, restaurants with high transaction frequency, making invoice issuance quick, convenient, and transparent.

1.2. Outstanding benefits of using electronic invoices

The transition to electronic invoices brings strategic benefits, directly affecting the business efficiency and management of the enterprise.

• Comprehensive cost savings: Electronic invoices help businesses significantly reduce the costs of printing, transporting, storing and preserving paper invoices. Many suppliers commit to storing electronic invoices for free for up to 10 years, helping to optimize long-term budgets.

• Improved efficiency and speed: Invoices are created, issued and sent to customers in just a few minutes, reducing waiting time compared to sending paper invoices by post. This process helps the accounting department reduce manual work, focusing on more important operations.

• Increased safety and security: Electronic invoices help reduce errors due to manual data entry and prevent counterfeit invoices. Professional electronic invoice systems often use high security technology such as Blockchain, ensuring data integrity and safety.

• Compliance with the law and reduction of tax risks: Using electronic invoices helps businesses comply with legal regulations on invoices. Electronic invoice software will automatically synthesize and transmit invoice data to tax authorities, helping businesses avoid errors and tax risks.
