# DIAN supplier registration guide

> Register suppliers to issue invoices in Colombia through the DIAN with Plemsi.

## Introduction

The [DIAN](https://www.dian.gov.co/) 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](https://plemsi.com) 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](/guides/co-dian).

## 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](mailto: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:

<Steps>
  <Step title="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](https://ayuda.plemsi.com/docs/tutoriales/configuracion/habilitar-documentos-electronicos-dian/)
  </Step>

  <Step title="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 Facturación](https://www.dian.gov.co/impuestos/factura-electronica/Documents/Numeracion2022-AutorizacionF.pdf)

    Please 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 Facturación](https://www.dian.gov.co/impuestos/factura-electronica/Documents/Numeracion2022-Habilitacion-F.pdf)

    The 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.
  </Step>

  <Step title="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](https://ayuda.plemsi.com/docs/tutoriales/configuracion/registrar-resolucion-dian/)
  </Step>

  <Step title="Create and configure your Plemsi account">
    Now you need a Plemsi account created and configured. We have to do this for you, so please contact us via Slack or [support@invopop.com](mailto:support@invopop.com).

    You'll need to provide us with this information about the supplier company:

    * NIT with verification digit
    * Name
    * Phone number
    * E-mail address
    * Address
    * City
    * Region (*Departamento*)
    * Postal code
    * Country
    * Tax Obligations (whether any of the following apply):
      * *Responsable de IVA*
      * *Gran contribuyente*
      * *Autoretenedor*
      * *Agente de retención en el impuesto sobre las ventas*
      * *Régimen Simple de Tributación - SIMPLE*
    * Business registration number (*Número de Registro Mercantil*)
    * Legal representative data:
      * Full Name
      * Identification number (*Cédula de ciudadanía*)
      * Phone number
      * E-mail address

    Also, from the previous steps, you'll need to provide us with the following:

    * The `TestID` code resulting from Plemsi authorisation in the DIAN
    * The numbering range registration document (*Resolución DIAN*)
  </Step>
</Steps>

At this point, you're ready to start sending invoices on behalf of the supplier. Head over to the [DIAN issuing invoices guide](/guides/co-dian) to continue.

## FAQ

<AccordionGroup>
  <Accordion title="What does a supplier need before issuing invoices in Colombia?">
    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](/guides/co-dian-supplier) walks through each step.
  </Accordion>

  <Accordion title="How do I register a supplier for Colombia?">
    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](mailto:support@invopop.com) with the supplier's company details so we can create and configure the Plemsi account. See the [supplier registration guide](/guides/co-dian-supplier) for the full checklist.
  </Accordion>

  <Accordion title="Does the billing numbering range authorization expire?">
    Yes. DIAN numbering range authorizations have both a number limit and an expiration date. When one runs out, the supplier's legal representative must file a renewal ("Solicitud de Habilitación de Numeración de Facturación") with the DIAN and associate the new resolution with Plemsi.
  </Accordion>

  <Accordion title="Do I need my own Plemsi account?">
    No. You can use Invopop's Plemsi billing account, or create your own and provide your credentials. In either case, contact us to configure the account — Plemsi account setup for Invopop suppliers is done by our team.
  </Accordion>

  <Accordion title="Do I need to register suppliers in the sandbox?">
    No. The Plemsi sandbox has a single pre-registered supplier with tax code `9015852843`, which all test invoices must use. Supplier registration only applies to the live environment.
