IQ eSign Facturae

It's the standard electronic invoice format in Spain, a structured XML file following an officially defined schema, rather than a simple PDF that looks like an invoice. It's mandatory for invoicing public administrations: any company selling to a public body in Spain needs to generate its invoices in this format and submit them through official channels — sending a PDF by email isn't enough. IQ eSign generates the Facturae file directly from Business Central based on the invoice you already issue in the ERP, automatically filling in all the mandatory fields of the official schema, with nothing to fill in by hand in a separate tool and no risk of the file being rejected because of a badly formatted field.

It's the General Entry Point for Electronic Invoices of Spain's General State Administration: the official platform through which companies must submit their invoices when the recipient is a public body (town councils, ministries, autonomous agencies and much of the public sector in general). Instead of sending the invoice by email or through each administration's own specific portal, FACe centralises receipt and routes it internally to the right body. The solution lets you submit your Facturae-format invoices to FACe directly from Business Central, with no need to log into the FACe portal manually for each invoice or manage that platform as a separate step disconnected from your ERP.

Yes. The invoice is digitally signed with your certificate (the same one you might use for other dealings with the administration), which guarantees both authenticity — that the invoice was genuinely issued by your company — and document integrity — that it hasn't been modified after signing — giving it full legal validity before the receiving administration. The whole process happens digitally, with no need to print the document, sign it by hand, scan it and upload it again, a process that besides being slow wouldn't meet the structured electronic invoice requirement demanded by public administrations, which don't accept a simple scanned image of a signed paper invoice.

The solution is built for electronic invoicing and keeps evolving alongside the regulations, particularly the Crea y Crece Law, which is progressively extending the electronic invoicing requirement to business-to-business (B2B) relationships too, not just towards public administrations as happens today with Facturae and FACe. The specific deadlines and requirements depend on company size and are being published in phases, so rather than giving you a generic answer, we analyse your specific case — your invoicing volume, your customers, your applicable deadlines — to tell you clearly what you need and by when, and get your Business Central ready with enough lead time before the requirement reaches you.

No. The entire cycle — generating the invoice in Facturae format from your Business Central invoice, digitally signing it with your certificate, and sending it to FACe or your customer — happens within the same ERP, with no external tools or manual steps that ever force you to leave Business Central. This avoids the common scenario of having to export data from the ERP, import it into a separate e-invoicing program, generate the file there, sign it with yet another tool and finally upload it to FACe by hand: each of those steps adds time and one more chance for something to go wrong or be left half-finished.

Facturae and Verifactu are two different requirements: Facturae is the invoice format, while Verifactu regulates how the software you bill with must behave (traceability, a chained hash and reporting to the Spanish tax agency), regardless of the format or the recipient. Business Central is rolling out the Spanish localization needed to comply with Verifactu together with Microsoft, and we help our clients get their environment configured and verified ahead of their deadline (January 2027 for companies, July 2027 for the self-employed and professionals).
