Facturama is a B2B software-as-a-service platform based in Monterrey that provides electronic invoicing solutions for businesses operating in Mexico. The company specializes in enabling small and medium-sized enterprises to generate Comprobantes Fiscales Digitales por Internet (CFDI), the mandatory electronic tax receipts required by Mexico's Tax Administration Service (SAT). Facturama functions as an Authorized Certification Provider (PAC), allowing it to validate, certify, and stamp electronic invoices with official tax validity. The platform supports both CFDI 3.3 and the current CFDI 4.0 standard, which became mandatory in April 2023. Facturama offers multiple product tiers including unlimited invoicing plans, mass invoicing capabilities that can process up to 1,000 invoices per Excel file, and an API for integration with existing enterprise resource planning systems and e-commerce platforms like Shopify. The company provides specialized complements including payroll receipts, payment complements, and Carta Porte for merchandise transport documentation. Facturama's pricing model includes flexible annual subscription plans starting at approximately 1,650 Mexican pesos, with pay-per-stamp options for additional transaction volume. The platform handles the complete invoicing workflow from document creation through cloud storage, generating both the required XML files and PDF representations with QR codes for verification. The company serves over 50,000 small businesses and startups across Mexico, positioning itself as an accessible fintech infrastructure provider that simplifies tax compliance through automated document management and direct integration with SAT systems.
