A simplified invoice is what is commonly known as a ticket. The tickets do not include fiscal data of the receiver and hence they are called “simple”.

On the other hand, we have the complete invoices or ordinary invoices. These are the official documents to record a commercial operation. To be valid, they must include a series of data from both the sender and the receiver. That is its main difference with the simplified ones.

No, the simplified tickets or invoices are not valid for the purposes of deducting VAT dues as they do not contain all the data necessary to do so. For this, it is necessary to request the complete invoices.

Electronic invoices can be considered:

That which is issued and received in electronic format already has the character of an electronic invoice.

The one that is received on paper but digitized. In order for it to have legal validity, it must meet a series of requirements such as digitization through software approved by the Tax Agency such as IVACK.

Yes, you have a period of 4 years to request invoices from the date of the ticket.

Indeed, yes.

IVACK requests the authorization of all its clients to perform these functions, for which we are fully empowered to do so.

We keep your invoices and tickets for 10 years.

For VAT purposes, it is only necessary to keep your invoices for 4 years, but to prevent you from having any other legal problem, we keep them for more years.

Once the deadline is over, we will notify you and allow you to download them completely so that you can save them yourself.

Any. We have proposed that you pay what is fair.

It is that complete invoice that replaces a ticket and that allows your customers to deduct VAT fees.

Take into account the following peculiarities:

· They must be current dated.

· Its numbering is different from that of ordinary invoices.

· It must be indicated that it is an exchange invoice and that the ticket it replaces (also indicating the date of the ticket it replaces).

· The ticket data should not be changed on the invoice you issue. That is, if the ticket has a non-current VAT rate, it must be indicated.

As the name indicates, a corrective invoice is one that modifies the data of another invoice in order to correct an error or if it does not comply with all legal requirements.

Corrective invoices also have a series of peculiarities:

· They must have a different numbering from the rest of ordinary invoices.

· The original invoice to be modified must be identified (number and date).

· The reason for its issue and the detail of the rectification.
Clearly indicate that it is a corrective invoice.

Yes, the law obliges ticket issuers to make the invoices requested by their clients during a period of 4 years from the issuance of the ticket.

It is an invoice that includes different operations carried out on different dates for the same recipient, provided that they have been carried out within the same calendar month.

When the recipient of these is a businessman or professional acting as such, the issue must be made before the 16th day of the month following the operations carried out.

Indeed, yes.

IVACK requests the authorization of all its clients to perform these functions, for which we are fully empowered to do so.

First of all don’t worry. Issuing an invoice for a ticket for a period already closed has no accounting or tax effect for you.

For that, it issues a payment (cancellation) of the ticket for its amount to the current date. Subsequently, it issues a new invoice also on the current date with the same amount.

Thus, at the current date, you have one negative entry and one positive entry, so its accounting or tax effect is zero.

Issues an invoice to the current date indicating that it is an exchange invoice.

It is a service that we make available to different businesses to facilitate the task of issuing ticket invoices.

A self-invoice is an invoice not issued by the business that has offered the service, but by the recipient or a third party.

In order to issue this type of invoice, you must first have authorization from the business and each time a new invoice is issued, the business must approve it.
