You can submit your invoices according to two types of format :

• PDF format
• XML format  

How to create your files before submitting your invoices :

The submission of invoices via the portal requires the transmission of files with one of the following extensions :

.pdf                                              .zip

   .xml                                .tar.gz

Creating a simple pdf invoice

From a word processor or spreadsheet, simply select the save as menu and select the "PDF (* .pdf)" type.

Creating a signed PDF invoice

You must use online signature software to electronically sign a PDF accounting document using an electronic certificate. Several solutions exist on the market including some free.

You should know that in Chorus Pro, the signed PDF is mandatory only for companies that have not implemented control to link invoices issued and deliveries or services that are invoiced.

Creating an invoice in PDF/A3 format

PDF file in which it is possible to include a file in XML format which contains the electronic data of the invoice. You can use a tool of the market or develop your own program internally.

Creating an invoice in XML format

Please refer to the External Specifications on the Chorus Pro Community website (https://communaute.chorus-pro.gouv.fr/documentation/external-specifications/?lang=en) to comply with the structuring and naming rules required to send your flows via the portal :

• Mixed XML : an XML invoice containing a PDF attachment (called the main attachment) that constitutes the reference invoice. This format can be used by structures that have already created PDF files and wish to transmit them by flow submission.
• Structured XML : invoice in XML format which constitutes the reference invoice and which makes it possible to send the invoice without using a PDF file attachment by simply providing the information in the tags required for its integration in Chorus Pro.

Creating an invoice in zip format

Select the relevant files and then right-click to display the context menu. Then click on the name of your file compression tool (ex: WinZip, PeaZip, IZARC or 7-Zip). We will illustrate the approach for 7-ZIP (free software) but it is roughly similar regardless of the tool used

Click on  Ajouter à l’archive (Add to the archive)…

Name the archive and select from the drop-down list the format of the zip archive.

Click on "OK". Your file .zip is created.

Creating a file « .tar.gz »

1. Select the files concerned, click on « 7-Zip » then on « Ajouter à l’archive (Add to archive)… ».

        2. Click on « Ajouter à l’archive (Add to archive)… » then name the archive in the« Archive » field.

Chorus Pro launches the recognition processing of the information contained in the PDF file.

6. Pre-filled invoice :

Once the processing is complete, Chorus Pro creates a pre-filled invoice from the data that has been recognized. The recognized data will be highlighted in blue in the corresponding fields.

Before validating the sending of your invoice, in order to allow a better recognition of the information provided in the invoice :

• check the recognized information and correct it if necessary. If Chorus Pro cannot recognize a piece of information, the field is not populated and you will have to enter it manually,
• complete the invoice by filling in the information that has not been pre-filled.

Please refer to the appendix for details of the character recognition rules.

Rules to be respected

Character recognition requires compliance with certain rules so that the information specified on invoices can be read correctly by Chorus Pro:

General principles :

Manual writing is not recognized. 

The information is scanned by a robot and there is no interpretation of the information provided.

The tool recovers all readable data but does not make any calculation (e.g.: If there are several VAT rates, a VAT TOTAL is required).

In order to avoid scanning all pages, regardless of the number of pages of the document submitted, a maximum of 3 pages will be scanned in the following order: first the first page, then the last page, and finally, if all the information to be recognized have not already been gathered, the penultimate page.

The pdf document must contain only the invoice : Do not add a purchase order or a delivery note following the invoice in the PDF file (these can be attachments).

Depending on the fields to be filled in, the tool performs a search based on keywords indicated on the invoice (ex: date, invoice, VAT...). so the keywords are therefore essential.

Data :

Separate the information and associate each data with a keyword. 

The data must be aligned with the keyword that defines it.

Do not add unnecessary letters (e.g.: Purchase Order N°= PO XXXX; The system will include the letters in the order number).

The first data that seems to meet the criteria is the one chosen by the tool. Therefore, avoid :

- Repeating the same data several times on the invoice.

- Filling in different data for the same « keyword ».

Data is intended for a computer system: respect the expected standard formats for the date, the amounts, the invoice and commitment numbers.

Characters :

In order for the data to be scanned, it must be isolated and legible :

- Words must not touch the boxes nor must letters be stuck together (e.g. : the currency must not be part of amounts),

- Avoid spaces in the codes and numbers you transmit.

Use colors and effects in moderation :

- Avoid color (red, pale colors…),

- Avoid bold or highlighted text,

- Avoid overprinting,

- Favour black writing on a white background.

3. Advice and remarks :

If you want to change the recognition criteria, you will need to send a request to which you must attach an example of the invoice you want to submit.
