What GRUPO SENIOR - SOLUÇÕES INTEGRADAS does

Grupo Sênior - Soluções Integradas is a privately held Brazilian accounting and financial services firm headquartered in Itaguaí, Rio de Janeiro, founded approximately in 1980 originally as Contabilidade Marinho. The company delivers integrated accounting, tax, payroll (DP), financial consulting, and tax credit recovery services, and claims to have recovered R$ 780M+ in tax credits for clients across a lifetime book of 5,000+ engagements over 45+ years of operation. It serves primarily SMB clients across general industries in Brazil, with a recently added Florida unit (2025) extending service to Brazilian entrepreneurs seeking US investment exposure.

The firm operates as an ecosystem of six wholly-owned sub-brands covering distinct professional service lines: Campos Marinho Contabilidade (core accounting), Y.Opportunity (strategic consulting), DigiSimples (digital transformation and process automation), Contabimóveis (real estate asset management and appraisal), RHS Consultoria (HR and organizational development), and Administração Judicial (judicial administration, mediation, and arbitration). No proprietary technology platform is disclosed — the offering is built around human expertise delivered as professional services, with the CEO (Nilton C. M. Junior) holding multiple regulated credentials including CRC-RJ, CRA-RJ, Judicial Administrator, FEBRABAN, and ABECIP certifications.

Revenue is generated through customized, quote-based professional service fees billed monthly on each engagement. Go-to-market is consultative and direct-sales led: the website prominently features an "Agende sua reunião" (Schedule a Meeting) call-to-action and displays the CEO's direct contact details (email and mobile), alongside phone, WhatsApp, and general email channels. Distribution is physical-consultative at the Itaguaí HQ and the Florida office, with no digital self-service channel and no publicly disclosed pricing tiers. Customer acquisition leans on the firm's long-standing regional reputation, client testimonials, and direct outreach rather than performance or paid marketing.
