In the following video, we will explain and share how to prepare, create, and review the 347 model of Odoo Community OCA that you can download from GITHUB . Remember that if you have an Odoo Enterprise Odoo. SH or On-Premise, you can install it at no cost on the server.

This manual for the 347 model of Odoo is based on the calculation of the 347 tax, which quickly and easily calculates the customers and suppliers that exceed €3,000 in total invoice (Base + VAT) during the previous year. This information can be communicated quickly and en masse to all our customers and suppliers for their review. 

We will also see how to prevent customers or suppliers that do not need to be declared in the 347 form, from being excluded from their contact record or from the invoice, facilitating the preparation of the tax in future years. It is important to remember that all customers, creditors, and suppliers in Odoo must always have the correct data of name, province, and NIF so that the 347 does not present errors. 

Once our 347 form is validated, we can generate the AEAT file to send it to the tax office and forget about this tax until next year, which is usually tedious but very easy to complete and validate with Odoo.

If you are a Contaldia client, remember that we calculate and submit the 347 form from your Odoo, to reduce errors and submit your taxes on time and correctly with your Odoo.

If you want to create and verify the 347 form using an Excel VAT book, because you have part of the invoices in a previous program or because you want to verify the data that appears in Odoo Enterprise, you can follow this tutorial to create a 347 form with your Excel VAT book from your Odoo.
