Frequently Asked Questions

What is an invoice?

An invoice is a commercial and tax document that certifies the sale of products or the provision of services between a company, freelancer, or professional and a client. It is an essential element for any business, as it serves as legal and accounting proof of a completed financial transaction.

An invoice includes important information such as the details of the issuer and the client, the billed products or services, the price, the applicable taxes (VAT), the issue date, and the total amount to be paid. Thanks to this information, invoices allow businesses to maintain accurate control of income, expenses, and tax obligations.

Issuing invoices is mandatory for companies and self-employed professionals in Spain when carrying out economic activities, whether through the sale of goods or the provision of services. In addition, regulations require businesses to keep invoices and their copies for the legally established period in order to comply with tax and accounting obligations.

Invoices are also essential for the financial management of a business, as they help track pending payments, record transactions, prepare tax returns, and maintain organized and transparent accounting. They also strengthen the relationship between businesses and clients by providing security, clarity, and legal support in every transaction.

In short, an invoice not only reflects a commercial transaction, but is also a key tool for administration, accounting, and tax compliance for any company or self-employed professional.

Does this tool issue legal invoices?

Yes, this JubiERP tool is fully valid for issuing legal invoices in Spain. Freelancers, companies, and professionals can generate invoices in PDF format and send them by email while complying with all current tax and accounting requirements.

In addition to making it easy to create professional invoices, JubiERP allows users to include all the mandatory invoice information, such as the tax details of the issuer and the client, applicable taxes, invoice number, issue date, and total amount. This ensures a safer, more organized, and regulation-compliant invoicing process.

While electronic invoicing is not yet mandatory for all businesses, PDF invoices remain completely valid. However, JubiERP already supports electronic invoicing and is adapted to systems such as Verifactu, promoted by the Spanish Tax Agency to improve invoice control, traceability, and digitalization.

Thanks to this, companies and freelancers can manage all their invoicing from a single software solution, automating processes, improving financial control, and ensuring legal and tax compliance in a simple, fast, and efficient way.
