Managing tax compliance in Spain has become increasingly complex due to the country’s strict fiscal regulations and evolving e-invoicing mandates. If your business operates in Spain and you are using WHMCS, it’s now vital to comply with Verifactu, the country’s official antifraud law, or TicketBAI (Basque Country). Therefore, whether you are a hosting provider, SaaS company, or service-based business, our Spanish Fiscal E-Invoicing module ensures your Spanish operations are fully aligned with national tax regulations.
This module generates tax-compliant invoices for Spanish clients using Fiskaly’s (https://www.fiskaly.com/signes/verifactu) SIGN ES API. It supports XML exports, CSV reporting, and full log tracking within WHMCS.

They sell you a module that doesn't work. I bought it two weeks ago and we're still reporting errors that prevent the module from working. They take a long time to respond, they don't test their developments, and you have to constantly write to them about the bugs.
