HoyFacturo is a cloud-based electronic invoicing platform operating in Mexico that provides businesses and individuals with tools to generate Comprobantes Fiscales Digitales por Internet (CFDI), the digital tax receipts required by Mexico's tax authority, the Servicio de Administración Tributaria (SAT). The platform specializes in offering compliant invoicing solutions for taxpayers who need to meet their fiscal obligations without downloading software or managing complex technical infrastructure. HoyFacturo supports multiple CFDI versions including both CFDI 3.3 and the current CFDI 4.0 standard, ensuring users remain compliant with the latest SAT specifications. The platform enables users to issue various types of fiscal documents including invoices, payroll receipts, payment complements, honoraria receipts, carta porte transportation documents, donation receipts, credit notes, and invoices with VAT withholding. Target users include freelancers, small businesses, and medium-sized enterprises seeking an accessible web-based solution to manage their tax compliance requirements. HoyFacturo operates through a cloud infrastructure where all user information and generated documents are securely stored in individual profiles, allowing complete accessibility from any device with internet connectivity. The platform incorporates accounting and statistics modules that help users track their business movements and maintain organized financial records. While HoyFacturo provides the invoicing generation interface, the actual certification or stamping (timbrado) of CFDI documents must be performed by a Proveedor Autorizado de Certificación (PAC), entities authorized by the SAT to validate and certify digital invoices. The platform positions itself as an emerging solution in Mexico's competitive electronic invoicing market, competing with numerous other platforms serving the country's tax digitalization needs.
