Invoice Maker for Vietnam

Choosing an invoice maker for Vietnam means prioritizing features that ensure compliance with local tax regulations and cater to specific business practices. A critical feature is the ability to accurately include the MST (Mã số thuế) tax code for both the seller and, where applicable, the buyer. This code is either 10 or 13 digits, with the latter used for subsidiaries. Your system must support transactions in Vietnamese Dong (VND), denoted as "D," and if foreign currency is used, the invoice must clearly state the exchange rate to VND. Furthermore, customizable templates are essential. These should allow for all mandatory information in Vietnamese, with foreign language text placed in parentheses and a smaller font size. Crucially, all e-invoices must be in a structured XML format and include a digital signature for authenticity.

Creating a legally compliant invoice in Vietnam involves adhering to specific General Department of Taxation (GDT) requirements, which have been mandatory since July 1, 2022.

1. Register with GDT: Before issuing e-invoices, businesses must register with the GDT, either directly or through an accredited service provider.
2. Include MST Codes: Ensure the seller's MST (Mã số thuế) is prominently displayed. If the buyer is a business, their MST is also mandatory. Parent entities and individuals use a 10-digit MST, while subsidiaries use a 13-digit MST.
3. Format and Language: Invoices must be in a structured XML format. The primary language must be Vietnamese. If foreign language text is necessary, it should be placed in parentheses or below the Vietnamese text, using a smaller font.
4. Currency and Totals: All monetary values should be in Vietnamese Dong (VND), expressed as "D". The total amount payable must also be stated in Vietnamese words.
5. Digital Signature: All e-invoices, except those from POS cash registers, require a digital signature from the issuer to ensure integrity.
6. GDT Verification/Reporting: Depending on your business type, invoices either receive a GDT verification code in real-time or are reported to the GDT on the same day of issuance.

The time of invoicing for goods is when ownership transfers, and for services, it's upon completion, regardless of payment.

Navigating Vietnam's e-invoicing landscape requires vigilance to prevent common errors that can lead to non-compliance and penalties. A frequent pitfall involves common mistakes with MST codes, such as incorrect formatting (e.g., not following the N1N2...N10-N11N12N13 structure for 13-digit codes), omitting the buyer's MST, or leaving the buyer's name blank. These errors can cause the tax system to reject the invoice.

Errors in currency formatting are another concern. While VND is the standard, if a foreign currency is used, failing to state the exchange rate to VND on the invoice is a mistake. Additionally, improper rounding on VAT invoices can lead to discrepancies.

Regarding template customization issues, ensure all mandatory information is present and accurate, including the correct tax rates. Issuing invoices at the wrong time (e.g., not at the point of goods transfer or service completion) is also a common procedural error. Remember that all e-invoices must be archived for 10 years in their original electronic form.
