Here we explain in simple terms what that is. electronic invoicing, Who is required to file, how to get started step by step, and how much it might cost.

What is electronic invoicing?
Electronic invoicing It's a sales invoice generated in a standardized digital format (XML), signed with a digital certificate, and validated by the Colombian Tax Authority (DIAN) before or at the time of delivery to your client. It's not a PDF you send by email: it's a legally valid tax document that is registered in the DIAN's system.
In Colombia, this isn't a standalone procedure, but rather part of a larger system. The DIAN (Colombian Tax and Customs Directorate) calls it the... Electronic Billing System, and brings together several documents:
- Electronic sales invoice: your sales and service support.
- Electronic equivalent document: It replaces the invoice in specific cases, such as the cash register ticket.
- Supporting document: for your purchases from those who are not required to issue invoices.
- Electronic payroll support document: back up payments to your employees.
- RADIAN: the registry where the invoice can circulate as a security (useful if you want to negotiate or finance it).
Who is required to use electronic invoicing in Colombia?
The short answer: if you regularly sell products or provide services, you're most likely obligated to issue invoices. The obligation to invoice arises from the sale or service itself, not from whether or not you're a taxpayer, as established by Article 615 of the Tax Code. And it's not just a legal matter: digitalization is already the norm among SMEs in the country, as these examples demonstrate. Statistics on digital SMEs in Colombia.
Today they are required to use electronic invoicing:
- Legal entities: SAS, Ltda., SA and other companies with economic activity.
- Those responsible for VAT and consumption tax.
- Independent professionals and merchants who invoice regularly.
- Taxpayers under the simplified tax regime.
Some very specific cases are excluded, such as certain low-income individuals who are not merchants. If you're unsure about your situation, the best course of action is to check your RUT (tax identification number) or ask your accountant before continuing to sell on paper. For a business that is just starting out... online store, Electronic invoicing from day one saves you headaches later.
How to get started with electronic invoicing step by step
Getting started is easier than it seems. This is the path we recommend to the businesses we support:
- Check your RUT. Log in to your DIAN account and verify that you have Responsibility 52 (electronic invoice issuer) active. If you don't, update your RUT online.
- Choose your tool. You can use the DIAN's free service or hire an authorized technology provider. We'll help you decide below.
- Enable yourself. Register on the enablement portal, configure your data and obtain your digital signature certificate (with the DIAN, free).
- Do some testing. The system asks you to issue some test invoices to validate that everything matches up before going into production.
- Start billing. Once enabled, you will generate valid invoices that are automatically reported to the DIAN.
The most common mistake we see is leaving the RUT (Taxpayer Identification Number) outdated. Without Responsibility 52 active, the system simply won't let you register, no matter how much software you have.
Requirements and the role of the DIAN
To issue electronic invoices, you basically need: a RUT (Taxpayer Identification Number) with Responsibility Code 52, an invoicing tool (either your own or one provided by the DIAN), a digital signature certificate, and an internet connection. The DIAN validates each invoice and issues the approval seal (CUFE), which makes it a legally valid document.
Another point that confuses many is the value of the UVT. Several regulations are calculated in UVT, a unit that the DIAN (Colombian Tax Authority) updates annually. For 2026, it was set at $52.374, according to Resolution 000238 of December 15, 2025. Understanding this figure helps you grasp the limits and penalties without getting lost.
Electronic invoicing software and providers
Here you have two paths, and choosing well depends on how much you invoice and how complex your business is.

| Basic technology provider | Medium-sized SMEs seeking integration | $30,000 – $80,000/month |
| Accounting software with invoicing | Companies that integrate inventory and accounting | $80,000 – $250,000/month |

Common mistakes when invoicing electronically
These are the pitfalls we most need to correct:
- Leaving the RUT without Responsibility 52, and then not understanding why it cannot be enabled.
- Confusing a PDF sent by email with a valid electronic invoice (it is not if it has not been processed by the DIAN).
- Do not issue the supporting document for purchases from people not required to issue invoices.
