Invoice Generator for Contractors in Vietnamese

Generating invoices as a contractor in Vietnam involves specific requirements to ensure compliance with local tax regulations. Electronic invoicing has become mandatory for most businesses since July 1, 2022, as part of Vietnam's digital economy shift. As of December 2025, nearly 99.37% of businesses participated in electronic tax services, highlighting the importance of digital tools in this landscape. For contractors, understanding the invoicing process involves incorporating necessary elements like the MST (Tax Identification Number) and adhering to VAT requirements.

A valid e-invoice in Vietnam must include detailed information about the seller and buyer, including names, addresses, and MST codes. Invoices must be in Vietnamese, with supplementary foreign language text allowed in smaller font sizes. This ensures that all financial documents meet the regulatory standards set by the Law on Tax Administration and other governing bodies. Failure to comply with these requirements can lead to significant legal and financial repercussions.

Harvest supports contractors by offering tools to track project-specific expenses and labor, which can be reflected in invoices, although it does not cater to specific Vietnamese tax and e-invoice regulations. This capability enables contractors to maintain accurate records of their work and expenses, a crucial aspect of effective financial management.

To comply with Vietnamese regulations, e-invoices must contain specific mandatory elements. These include the invoice name, serial number, a unique e-invoice number, and detailed seller and buyer information. Numbers must be in Arabic numerals, and the currency used must be Vietnamese Dong (VND), with the symbol "đ". Additionally, data from these e-invoices must be securely stored for at least 10 years.

For contractors, especially those in construction, invoicing can be complex due to the nature of progress-based work. Invoices are often issued upon the acceptance and handover of completed work items, whether payment has been received or not. This can involve the "cuốn chiếu" (rolling completion) or "đại cục" (overall completion) approaches, depending on the project scope.

While Harvest does not specifically include Vietnamese MST or VAT requirements, it allows contractors to add general tax information to invoices. This flexibility can help contractors organize their financial data effectively, though they may need additional tools or consultation for full compliance with Vietnamese regulations.

Harvest offers a comprehensive solution for contractors by enabling them to track project-specific expenses and labor, which can be seamlessly incorporated into invoices. Although Harvest does not provide MST tax code inclusion or specific VAT calculations for Vietnam, it supports contractors in managing work-related financial data efficiently.

Using Harvest, contractors can organize their expenses and labor costs accurately, allowing for detailed invoicing that reflects the true cost of projects. This is particularly beneficial in the construction industry, where detailed tracking of materials and labor is essential for accurate billing and project management.

Moreover, Harvest's invoicing capabilities help contractors maintain transparency with clients by clearly outlining project expenses. This not only aids in ensuring client satisfaction but also supports contractors in maintaining clear records for financial audits or regulatory reviews.

Invoicing in Vietnam presents unique challenges, particularly for contractors who must navigate complex regulatory frameworks. The transition to electronic invoicing has been significant, with e-invoice adoption seeing a 380% increase from 2024 to 2025. However, this shift also demands that contractors stay informed about the latest compliance requirements, such as MST inclusion and VAT specifications.

One of the primary challenges is ensuring that invoicing practices align with the latest regulatory updates, such as those stipulated in Law No. 38/2019/QH14. Contractors must be diligent in maintaining accurate records of taxable transactions to avoid penalties.

While Harvest offers robust tracking and invoicing features, contractors may need to complement these with additional resources to meet specific Vietnamese compliance requirements. This approach ensures that they can leverage Harvest's strengths in expense and labor tracking while adhering to local tax laws.
