In 2025, electronic invoicing is no longer just a trend—it has become a legal requirement in El Salvador. This process, a key part of the country’s tax modernization efforts, represents an excellent opportunity for businesses to optimize operations, reduce costs, and comply with the regulations established by the Ministry of Finance.
What is an Electronic Invoice?
An electronic invoice, known as a Electronic Tax Document (DTE), is a fiscal document that is generated, digitally signed, and transmitted electronically, using structured standards such as JSON. After submission, the Ministry of Finance assigns a Reception Seal, which grants the document legal validity.
Who Is Already Required to Use It?
- Large taxpayers (such as banks, telecommunications companies, etc.) began issuing DTEs in early 2025.
- Starting July 1, 2025, many other taxpayers have been or will be notified to comply with this obligation.
Notifications are personalized, providing specific deadlines and dates to begin the process.
Why Is It Important to Implement Electronic Invoicing?
- Reduced operational costs: eliminates paper usage, printing, and physical storage.
- Lower error rates and greater accuracy in financial records and tax filings.
- Compliance and traceability, thanks to structured systems and official digital seals.
- Positive environmental impact, due to reduced paper consumption.
- Improved tax collection: the system has increased VAT revenue between 3.5% and 8.7% of GDP between 2017 and 2024.
- Digital delivery synchronized with intermediaries: invoices can be quickly sent to customers via email, WhatsApp, or client portals.
Options for Issuing DTEs
- Free System from the Ministry of Finance: Ideal for small businesses that issue fewer than 100 invoices per month or generate sales of up to USD 10,000, and that do not require customization.
- Private Electronic Invoicing Systems (Paid): Suitable for companies with higher transaction volumes or those requiring additional modules such as inventory management, accounts receivable, or customized PDF invoices. These solutions usually include cloud storage and technical support, with costs starting at approximately USD 100 per year.
Adoption Process: Step by Step
- Check your status on the portal factura.gob.sv using your NIT.
- Request access to the testing environment:
- 15 days if using the free system.
- Up to 2 months if using the API transmission system.
- Obtain your electronic signature certificate (e.g., JWT), required to sign DTEs.
- Complete the required tests established by the Ministry of Finance:
- Between 10 and 90 tests per DTE type, depending on the system used.
- Request authorization to operate in the production environment and start issuing legally valid DTEs.
- Store DTE files (JSON + readable version) for 15 years.
- Define a contingency plan: generate and record contingency or invalidation events if the system fails.
Key Recommendations
- Check your schedule: the notification you receive determines when you must start. If you have not yet received a date, stay prepared.
- Evaluate your provider: choose between the government’s free system or a comprehensive solution depending on your needs.
- Train your team on platform usage, certificate management, roles, and operational protocols.
- Ensure continuous backups: whether local or cloud-based, store documents for the legally required period.
- Use this transition as an opportunity to modernize related processes, such as invoicing, inventory management, and customer communication.
