What Fortec Informatica does

Fortec Informatica, operating under the trade name Isistem Gerenciador Financeiro, is a privately held Brazilian software company founded in 2013 and headquartered on Avenida Paulista in São Paulo (CNPJ 51.052.190/0001-21). The company develops and sells Isistem, a self-hosted financial management and billing platform purpose-built for small and medium-sized web hosting companies and resellers in Brazil. The product is delivered as a downloadable PHP 8.1 / MySQL application running on Apache/Linux servers, protected by ionCube Loader encryption, and is installed on the customer's own infrastructure rather than run as multi-tenant SaaS.

Isistem consolidates recurring billing, accounts receivable, expense tracking, client portal management, support ticketing, affiliate program administration, and electronic service invoice (NFSe) generation into a single interface. Its core differentiator is depth of localization: the platform natively integrates with more than 13 Brazilian payment gateways (PagHiper, PagSeguro, Mercado Pago, PIX Sicredi, PIX Banco Inter, Gerencianet, ASAAS, Iugu, Pagar.me, OpenPix, Efí Bank, Juno, F2B, BitPay), 13+ hosting and virtualization control panels (cPanel/WHM, DirectAdmin, Plesk, CyberPanel, VestaCP, KeyHelp, Proxmox, SolusVM, Virtualizor, VMware, TCAdmin, Pterodactyl, VoxStreaming, CentovaCast, SonicPanel), three domain registrars (Registro.br, ResellerClub, Namecheap), and multiple Brazilian municipal fiscal invoice APIs. The company distributes entirely online via a product-led growth motion: a public demo environment, free trial, and self-serve subscription at R$ 34.90/month standard or R$ 27.92/month on an annual plan, with a reseller program priced at R$ 29.90/license (10-license minimum). The 5-person organization has shipped over 80 product versions since launch and shows no external funding, parent company, or institutional ownership.

Regional players

• Conta Azul: Conta Azul is a Brazilian SaaS for SMB financial and operational management (banking, billing, accounting). It is comparable to Isistem as a Brazilian SaaS serving SMB finance workflows, but its horizontal Brazilian SMB focus differs from Isistem's narrow web-hosting-vertical specialization.

Broad incumbents

• Stripe Billing: Stripe Billing is a global subscription billing and invoicing infrastructure used by SaaS and recurring-revenue businesses, including operations in Brazil. It overlaps with Isistem's recurring billing and invoicing functionality but as part of a much broader payments platform, not a hosting-vertical specialist.

Direct peers

• ClientExec: ClientExec is a long-standing billing and support platform for hosting companies and ISPs, with recurring billing, provisioning, and helpdesk features. It is comparable to Isistem as a direct hosting-vertical billing competitor, though its footprint is now mostly legacy/incumbent SMB hosting customers.
• Blesta: Blesta is a commercial hosting billing and client management platform with module-based integrations to control panels, payment gateways, and domain registrars. It is directly comparable to Isistem in product category (hosting billing SaaS) and target customer (hosting providers and resellers).
• HostBill: HostBill is a commercial billing, automation, and client management platform built for web hosting, reseller, and cloud providers. It competes head-to-head with Isistem on the same core use case (recurring billing + control panel provisioning), with a broader international footprint but less Brazil-specific localization.
• WHMCS: WHMCS is the dominant global billing and automation platform for web hosting companies, offering recurring billing, provisioning into cPanel/Plesk, and domain/SSL management. It is the most direct functional competitor to Isistem in the hosting billing category, though it serves a global market rather than a Brazil-specific niche.
• BoxBilling: BoxBilling is an open-source billing and client management system for hosting companies, covering invoicing, ticket support, and order management. It targets the same SMB hosting provider niche as Isistem with a downloadable self-hosted model similar to Isistem's distribution approach.
