Invoice App for Vietnam

To ensure adherence to Vietnamese tax laws, an invoice app must fully comply with the country's mandatory e-invoicing regulations, which have been in effect for most businesses since July 1, 2022. Recent updates, including Decree 70/2025/ND-CP and Circular 32/2025/TT-BTC, further refine these requirements, effective June 1, 2025.

• Mandatory E-invoice Format: The app must generate invoices in the legally binding XML format, with a PDF copy often provided for convenience.
• Digital Signatures: Electronic invoices generally require a secure digital signature to authenticate the issuer and prevent tampering. This signature must be applied within one day of the invoice issuance.
• Tax Authority Codes: Understand the two types of e-invoices:
  • Authenticated E-invoices: These receive an authentication code from the tax authority (General Department of Taxation - GDT) before being sent to the buyer. Larger or high-risk businesses typically use this type.
  • Unauthenticated E-invoices: These are sent directly to the buyer, with the invoice data transmitted to the GDT on the same day of issuance.
• Mandatory Content: Invoices must include specific details such as the seller's and buyer's names, addresses, and tax codes, invoice number, issuance date, and comprehensive transaction details including goods/services description, quantity, unit price, and VAT rate. All text must primarily be in Vietnamese, with foreign language translations in parentheses and a smaller font.
• VAT Calculation and Reporting: The app should accurately calculate Value-Added Tax (VAT). Vietnam primarily uses a "credit method" for VAT calculation, allowing input VAT to be offset against output VAT, which is common for foreign-invested enterprises. The standard VAT rate is 10%, though a temporary reduction to 8% applies to certain goods and services until December 31, 2026.

Successful integration with local payment methods is crucial for businesses operating in Vietnam. An effective invoice app should offer:

• Support for Bank Transfers and Cash Payments: Many Vietnamese businesses rely on traditional payment methods such as bank transfers and cash. An app should facilitate these transactions smoothly.
• Integration with Popular Vietnamese Payment Systems: To enhance convenience, the app should integrate with local payment systems that are widely used in Vietnam, ensuring seamless transactions.

Invoice apps must cater to the unique needs of SMEs, which often require straightforward, efficient solutions. Key features include:

• User-friendly Interfaces for SMEs: The app should offer a simple, intuitive interface that minimizes the learning curve for users.
• Features for Quick Invoice Issuance from POS Systems: Quick and efficient invoicing capabilities are essential, especially for businesses that operate point-of-sale systems and require rapid transaction processing.
