Electronic invoicing for freelancers in Spain: what changes before you invoice

Spain's B2B electronic invoicing rules are pushing freelancers toward more structured workflows. But the invoice is only the last step. Before that, you still need signed quotes, contracts, approvals and scope changes.


Quick answer

If you are a freelancer in Spain working with businesses or other professionals, electronic invoicing will matter for your B2B invoices. SignQuick does not replace compliant invoicing software. It helps with the step before the invoice: getting quotes, service agreements, authorizations and NDAs signed by the client.

Electronic invoicing is not just a PDF

Under Spain's B2B electronic invoicing framework, an electronic invoice is not simply a PDF attached to an email. It must be issued, transmitted and received in a structured electronic format through the applicable system.

That means freelancers who still use Word, Excel or manually created PDFs should start separating two workflows: fiscal invoicing on one side, and client approval documents on the other.

Electronic invoicing and VERI*FACTU are different topics

Electronic invoicing regulates how B2B invoices are exchanged. VERI*FACTU and Spain's invoicing system rules regulate the technical requirements for invoicing software: integrity, traceability, preservation and tamper resistance.

For invoices, use compliant invoicing software. For signed quotes, contracts and approvals, use an electronic signature workflow such as SignQuick.

The missing step: signed approval before invoicing

The invoice is usually the administrative end of the project. Before that, the client needs to accept the work, the price, the scope, the payment terms and any revisions or extras.

  • Signed quote.
  • Service agreement.
  • NDA.
  • Work authorization.
  • Scope change or extra work approval.
