In Spain, taxpayers’ sales invoices are recorded in the national VERI*FACTU system. To record your invoices, you must use invoicing software such as Eemel.com, which can communicate with the system. In order for Eemel.com, through our partner Fiskaly, to report your invoice data to the Tax Agency on your behalf, you must sign a collaboration agreement as part of the connection process.

The VERI*FACTU connection is made from the Orders page. When you activate VERI*FACTU, the system will request the information to be stored with the Tax Agency.

If you are representing a company and not acting in your own name, please also complete the representative fields so that the collaboration agreement is addressed to the correct signatory.

Sign the collaboration agreement using your national electronic certificate, for example with the Autofirma program developed by the Spanish Ministry of economic affairs and digital transformation.

In Spain, invoice numbering must:

Eemel.com creates continuous series without gaps for sales invoices and credit notes, but you are responsible for maintaining chronological order. Send your invoices on the same day as the invoicing date so that the invoice date is always the same or later for higher invoice numbers.

Sales invoice numbering starts at 1000 unless you set an alternative number in Settings → Invoicing settings → Invoice numbering start number. Credit notes start with the “R” series from the same start number.

If your company already has an existing number series without a prefix and you are changing software, set Settings → Invoicing settings → Invoice numbering start number to the next number in your sequence so that the first sales invoice will use it.

If you have also been using a credit note series with the “R” prefix, after issuing the first sales invoice, set the Invoice numbering start number for credit notes to the next highest number in that series so that the first credit note uses it.

Once the collaboration agreement is signed, sales invoices sent from Eemel.com will be recorded in the VERI*FACTU system as part of the sealing process. During sealing, the invoice number will also be assigned.
