What finkok does

FINKOK (legal entity: FINKOK, SAPI DE CV) is a Mexican Authorized Certification Provider (PAC) founded in 2014 and headquartered in Morelia, Michoacán, Mexico, specializing in electronic invoicing (CFDI — Comprobantes Fiscales Digitales por Internet) for businesses operating in Mexico. The company delivers its core service through SOAP/XML WebServices APIs that partner applications consume for CFDI 4.0 certification, Nómina (payroll) invoicing, Retenciones (withholding tax invoices), and the new SAT-mandated invoice cancellation scheme. FINKOK operates its own non-virtualized infrastructure across two US data centers — Santa Clara, California (primary, co-located with Facebook's facility) and Phoenix, Arizona (redundant backup) — with full-stack redundancy (VRRP firewalls, SMLT switches, HSRP links, NIC bonding) and a claimed 100% uptime record since inception.

The platform is complemented by a cloud-based administrative panel (Business Partner Panel / BPP) for invoice management, a free test environment (Kit de Pruebas), 24/7 support, and a dedicated system integrator assigned to each business partner at no cost. FINKOK's commercial model is differentiated by OnDemand usage-based pricing — customers pay only for invoices issued at month-end, with a 500-invoice monthly minimum and a 30-day free trial — positioning it as the only PAC in the Mexican market to offer this billing structure. The go-to-market is hybrid: API-first for high-volume enterprise and integrator channels, paired with direct sales-led onboarding for end-customers across industries including healthcare, government, retail (Cinepolis, Marti.mx), technology, education, non-profit, and manufacturing.

The company is privately held with no disclosed funding rounds, no parent company, and no public listing. Its 16-person team is led by an experienced C-suite (CVO, CFO, CIO, CBDO, CISO, CCO), and the integrated management system is aligned to ISO 9001:2015 and ISO 27001:2013. Revenue is not publicly disclosed; customer logos span a diversified mid-market and enterprise base with notable infrastructure-management track record handling high-traffic Mexican properties.
