As most of you know, as of July 1, 2017, companies that meet certain billing conditions are required to provide detailed information on each invoice they issue and receive within a maximum of 4 days.

Although this information will be explained below, we can summarise that this affects companies with a monthly VAT return and based in Spain, excluding the Basque Country and Navarre, from 1 July. Most of them are large companies or those with a high percentage of exports.

For all other companies, the obligation is expected to arrive on 1 January 2018 or shortly thereafter.

SII Project

Until the current version 10, Odoo SA has always supplied the product in English and with "generic" accounting. From then on, the translation into Spanish and the adaptation to the Spanish tax regulations is a task entrusted to the professional community in Spain.

That is why, as usual when there are these types of regulatory changes, this community of professionals has organized itself to jointly provide a solution to this need.

The work began in January and we took advantage of the days in June in Barcelona to give it an important boost that almost left it finished (see more info of the Conferences).

Although it has been the work of many people, I think it is fair to thank especially Acysos for leading the development and Comunitea, Diagram, Minorisa, Studio73, Factor Libre, Otherway and Tecnativa for their important contributions.



How does the module work?

Will it affect the posting of invoices?

The idea has been that our accountant will not be affected by this change and will continue to do things as before.

We have several options when it comes to sending the bill:

  • Once the invoice is validated.

  • At a specific time.

  • Time interval after the validation of the invoice.

Once this and some other parameters are configured, we will see that a new tab appears in the invoice model, called SII.

Let's say our accountant has decided that the invoice will be sent after being validated. Once this has been done, Odoo will connect to the AEAT server and send the invoice. Thanks to the Odoo connector, in the event of an error (server down, for example), the invoice will be saved in the queue and sent as soon as possible.

 In the case that everything went correctly, the information we'll see will be that of the image next to it.

More information about the SII

Who will be affected by the SII? All VAT-taxable persons? 

The new IRS will be applicable on a mandatory basis to taxable persons who are currently required to self-assess VAT on a monthly basis:

  • Registered with REDEME (Monthly VAT Return Registry)

  • Medium and large companies (turnover over 6 million euros)

  • VAT groups

The new SII will also be applicable to taxpayers who voluntarily choose to use it.

It is important to note that it is an obligation of the Tax Agency (AEAT), so that companies that pay taxes in the provinces (Euskadi and Navarra), will not be affected until January 2018.

 What will be the basic lines of operation of the SII? 

Taxpayers under the SII are obliged to keep, through the Electronic Headquarters of the AEAT, by means of the electronic supply of the invoicing records, the following Registry Books:

  • Record book of invoices issued.

  • Logbook of incoming invoices.

  • Registry book of investment goods.

  • Register of certain intra-Community transactions

To do so, they must send the AEAT their invoicing details, with whose information the different Registry Books will be configured almost in real time.

This information will be sent electronically, specifically through Web Services based on the exchange of XML messages.

The structure of this shipment will have a common header with the information of the holder of each record book, as well as the information of the year and period in which these operations are recorded. This header will be accompanied by a block with the contents of the invoices.

In addition, the electronic supply of invoice records will be carried out by means of a web form in the case of taxable persons who carry out only a few transactions or when they wish to send individual invoice records in isolation.

This information will be provided in accordance with the registration fields approved by the Minister of Finance and the Civil Service through Ministerial Order HFP/417/2017 of 12 May.

For official information, see AEAT's SII page.



With this, we want to convey to all our customers the certainty that Odoo is prepared to tackle both this change and all those that may arise over time.

Thanks to the Odoo open source model, it has been possible to carry out collaborative work between a number of partners in the Spanish community, which has once again enabled us to present this tool in time for our customers to comply with their tax obligations. All this, at a more than acceptable cost.
