In Colombia, a massification project is underway to promote use of e-invoicing in the country. The current e-billing system, not at all widely implemented, is under in-depth revision and will be totally replaced by the new schema, which the government intends to extend to 100% of Colombian issuers.

Tax authority: 

DIAN - National Customs and Tax Directorate

Mandatory status

In accordance with tax reform - Law 1819 of 2016, Article 308:

“Taxpayers required to declare and pay VAT and consumption tax must issue electronic invoicing as of January 1, 2019 under the terms established in the regulation. Throughout tax years 2017 and 2018, taxpayers required by the tax authorities to issue electronic invoicing shall be selected on a sectorial basis in view of the high risk of evasion identified therein and the lesser effort required for its implementation.”

Administrative transactions required

Taxpayers wishing to implement the new e-invoicing model on a voluntary basis must register with the DIAN as electronic invoice issuers.


The electronic signature consists of a private key and a certificate issued by a certification authority approved by the ONAC, used to sign the bill electronically and create the "technical key" cited in the " FISCAL CONTROL" section.

Print format

The electronic invoice issuer must provide the recipient with a graphic representation of the electronic invoice in printed format or in digital format including the specifications defined by the DIAN, such as e-signature, the CUFE or the QR code, among others.


The massification project also foresees the use of a specific UBL (Universal Business Language) type invoice format, based on XML standards.

Fiscal control

Voluntary issuers currently have to use a range of numbers issued by the DIAN to identify each invoice, as well as submitting the monthly "technical key" consisting of a unique sequence of digits.

To sum up, the tax application process controlled by the Tax Authority consists of the automatic verification of 8 validations that each document must undergo: numbering, certainty that the document has been sent within the terms, RUT, taxpayer registration, CUFE, software status and e-signature.


Safekeeping of the original electronic document is mandatory for issuers and recipients for the period laid down in the tax statute.
