Introduction

The DIAN in Colombia stands for Dirección de Impuestos y Aduanas Nacionales (National Directorate of Taxes and Customs). It is the government agency responsible for managing and overseeing tax collection, customs operations, and facilitating international trade. Businesses in Colombia must be registered with the DIAN and have an active RUT (Registro Único Tributario) to issue electronic invoices. Invopop has partnered with Plemsi to issue invoices in Colombia (DIAN). Before you can issue invoices on a supplier’s behalf, the supplier must authorize Plemsi in the DIAN and have a configured Plemsi billing account. This guide walks you through that onboarding process. Once a supplier is registered, continue with the companion guide: Colombia: Issuing invoices.

​
Prerequisites

To register a supplier in Colombia, you will need:
  • Supplier details, including company name, RUT, address, and municipality code issued by the DIAN.
  • The supplier’s legal representative available to authorize Plemsi in the DIAN and request the billing numbering range.

​
Sandbox

Plemsi provides a sandbox environment that you can use to test the issuance of invoices and credit notes end-to-end without fiscal or legal consequences. If you wish to use this environment, please contact us via Slack or support@invopop.com so that we enable your Invopop workspace to use it. In the sandbox there’s only one supplier enabled — its tax code is 9015852843 — so no supplier registration is needed there. The steps below apply to the live environment only.

Register a supplier

You can invoice using the Plemsi provider on behalf of multiple suppliers. For each supplier, these are the steps you’ll need to follow:
1

Authorise Plemsi to issue invoices on your behalf

First, the supplier’s legal representative must authorize the Plemsi technology provider to issue invoices on your behalf in the DIAN.The following guide explains how to do it, but note that you’ll have to skip the last few steps in the Plemsi user interface. We’ll take care of them for you later in this guide:📘 Habilitar documentos electrónicos DIAN
2

Get a billing numbering range authorisation

Next, the supplier’s legal representative must get a DIAN authorization for the billing numbering range you wish to use in your invoices. This guide explains how to do it:📘 Solicitud de Autorización de Numeración de FacturaciónPlease note that these authorizations have a limit and an expiration date. If you need to renew an existing one, this other guide explains how to do it:📘 Solicitud de Habilitación de Numeración de FacturaciónThe DIAN will provide you with an 1876 form at the end of the process. Keep it at hand; you’ll need it in the following steps.

Authorise Plemsi to use the numbering range

Now, the supplier representative must give the Plemsi technology provider permission to use the numbering range when issuing their invoices.The following guide explains how to do it, but again, note that you’ll have to skip the last few steps in the Plemsi user interface. We’ll take care of them for you later on:📘 Asociar una resolución o numeración DIAN

FAQ

The supplier must be registered with the DIAN with an active RUT (Registro Único Tributario), authorize Plemsi as their technology provider in the DIAN, and hold a valid billing numbering range authorization. The supplier registration guide walks through each step.
The supplier’s legal representative authorizes Plemsi in the DIAN, requests a billing numbering range authorization (the DIAN issues a form 1876), and associates that resolution with Plemsi. Then contact us via Slack or support@invopop.com with the supplier’s company details so we can create and configure the Plemsi account. See the supplier registration guide for the full checklist.
