Lyon Métropole commits to simplifying your invoicing. Are you a supplier of goods and services for Lyon Métropole? Are you a public entity and need to send an invoice to Lyon Métropole?

Starting on 1 January 2017, you can transmit and track your invoices free of charge electronically to save time and money.

Why dematerialize your invoices?

Aiming to modernize public action and improve invoice processing time, the French government has committed to a process of dematerializing invoice processing. Starting on 1 January 2017, suppliers of the public sector and public entities will be required to transmit their invoices electronically. This requirement will be progressively implemented until 2020, according to company size.

In addition to reducing your carbon footprint, electronic invoicing has many other advantages:

  • guarantee that your invoice has been received;
  • possibility of following the processing of your invoices live;
  • time saved in sending, processing and tracking your invoices;
  • savings on expenses for sending and storing invoices on paper.

Information on Lyon Métropole

After identifying yourself on Chorus Pro, you will need specific information in order to deposit your invoice and transmit it to Lyon Métropole. This information is found on the contractual document you received (order form, commitment voucher, market, service order, etc.) from your Lyon Métropole contact.

  1. I enter the Métropole identifier in the "SIRET / Identifier" field; this is the SIRET code of Lyon Métropole shown on the contract document relating to my invoice:
    • Please note: Lyon Métropole has several SIRET numbers, so be careful!
    • Main budget: 200 046 977 00019

  2. I do not complete the "Contract number" field.

    • Attention: the form of the "reference to be quoted" needs to be observed. It starts with the letter "E" or "C" immediately followed by a series of figures, without spaces or hyphens.
