Diverza is a Mexican electronic invoicing and digital tax compliance provider that operates as an authorized Proveedor Autorizado de Certificación (PAC) by the Mexican tax authority SAT. Founded in 2003 by Marcela Cisneros López and José Luis Ayala, the company provides certified electronic invoicing services, digital seals, and electronic signature solutions to businesses and professionals across Mexico. As a PAC, Diverza is authorized to issue, certify, and store fiscal documents on behalf of the SAT, meeting regulatory requirements that include maintaining a minimum subscribed and paid-in capital of 10 million pesos. The company's core offerings include electronic invoicing (CFDI) services, carta porte compliance, payroll digitalization, and tax risk management tools that monitor suppliers appearing on SAT blacklists under articles 69 and 69-B of the Federal Fiscal Code. Diverza has developed specialized solutions for various professional sectors, including medical professionals through its Ticket Fiscal product, which enables patients to easily download fiscal receipts for consultations and medical services. The company serves approximately 450,000 registered users, with 250,000 active clients, operating through 25 offices throughout Mexico. In 2011, Diverza received Series A funding from Alta Ventures Mexico, which recognized it as the largest e-invoicing provider in Mexico at that time. The company positions itself as bridging digital and traditional approaches to professional business management, with a focus on regulatory compliance, security, and automation of fiscal processes. While Diverza provides technology tools for financial and tax compliance, its primary function is regulatory technology rather than core fintech services.
