Jettax

What Jettax does

Jettax Tecnologia e Servi\u00e7os Online Ltda. is a Brazilian SaaS company founded in 2017 and headquartered in S\u00e3o Paulo that builds fiscal automation software for accounting offices. Its core offering is a cloud-based platform that connects directly to Brazilian tax authorities (SEFAZ) and more than 2,200 municipalities via A1 digital certificates, automatically capturing NF-e, NFC-e, CT-e, CFe and NFSe fiscal documents without requiring clients to submit XML files. The product is organized into six modules: Federal (NFe/NFCe capture and PIS/COFINS/ST), Servi\u00e7os (NFSe across 2,200+ municipalities plus 'Tomados de Fora' in 600+ cities with integrated retention auditing for IRRF, INSS, ISS, PIS, COFINS and CSLL), Simples Nacional (daily DAS calculation with automatic Fator R, ST and monophasic application), Preven\u00e7\u00e3o (daily monitoring of e-CAC, DEC-SP and DUC-SP), Automa\u00e7\u00e3o ICMS (24+ audit stages per item with automatic DARE generation for ST and DIFAL) and Automa\u00e7\u00e3o SPED (batch SPED import, validation and transmission).

The platform includes an open API and native integrations with six major Brazilian accounting ERPs (Contmatic, OMIE, NIBO, Confi, WebCounter, Acess\u00f3rias), allowing Jettax to operate as a fiscal data layer that feeds existing office systems rather than displacing them. Revenue is generated through modular SaaS subscriptions on an annual billing cadence with annual price readjustments, sold via a hybrid motion combining direct sales (commercial demo requests), self-serve adoption (start with one module and expand) and ERP-channel distribution. Marketing is content-led, anchored by a weekly Fiscal News newsletter, blog, free resources and social presence targeting Brazilian accounting professionals.

Jettax is controlled by Vela Software Brazil Participa\u00e7\u00f7es LTDA, a holding entity headquartered in Belo Horizonte that aggregates vertical software assets, placing the company within a roll-up ownership structure rather than as an independent venture-backed or bootstrapped entity. A related operational entity, MXM JETTAX SOLUCOES E SERVICOS LTDA, appears in the website footer.
