Contassesc Contabilidade

What Contassesc Contabilidade does

Contassesc Contabilidade e Assessoria Empresarial is a privately held Brazilian accounting and tax advisory firm founded in 1993 in Catanduvas, Santa Catarina, by Valdenir Menegat and (initially) Joel da Silva. Following a 2004 partnership transition in which Aliciane Novello joined as managing partner, the firm repositioned itself around consultive ("contábil consultiva") accounting, emphasizing tax planning, tax regime optimization (Simples Nacional, Lucro Presumido, Lucro Real), tax recovery, and ongoing compliance rather than pure transaction processing. The company operates from six offices across Santa Catarina — Joaçaba (regional HQ), Chapecó, Catanduvas, Concórdia, Videira, and Celso Ramos — and serves clients nationwide, with reported metrics of 300+ employees, 3,000+ active client companies, and R$ 18 billion in client billing under management.

The core product stack centers on the Diagnóstico Contassesc, a free fiscal diagnostic that maps tax regime suitability, identifies risks, and projects savings, followed by recurring monthly advisory engagements with continuous tax review. Supporting products include company formation (Abertura de Empresa), an Onvio-powered client portal for ongoing access, and free browser-based simulators (Custo Efetivo de Empregado and Fim da Escala 6×1). Technology is described as an integrated accounting/fiscal/HR ecosystem with automated tasks and secure backups; the visible client-facing layer is the third-party Onvio platform, and no proprietary AI/ML capabilities are disclosed.

Commercially, Contassesc runs a consultative sales motion with WhatsApp as the primary contact channel, the free diagnostic as the lead magnet, and quote-based, subscription-style recurring fees for ongoing services. Marketing is content-led through a blog, meConta newsletter, and organic social (Instagram, Facebook, YouTube, LinkedIn). The customer base spans small and medium Brazilian businesses, entrepreneurs opening new companies, and named enterprise groups (Pegoraro, Passarella, Viza), with an average reported client tenure of 11 years and 30+ years of operating history as the primary brand assets.

Core offering

Contassesc provides recurring accounting, tax, and fiscal advisory services to companies, covering tax-regime analysis, continuous tax reviews, compliance monitoring, tax recovery, cash-flow optimization, and company formation. The service process begins with a free diagnostic that maps a client's fiscal structure, identifies tax-regime inefficiencies, compliance gaps, and recovery opportunities, and produces a structured optimization plan before recurring monthly support.

Product overview

Contassesc Contabilidade offers a unified accounting and tax advisory platform centered on its consulting approach that transforms data into business growth. The core offering is its advisory accounting service spanning tax planning, company formation, and ongoing compliance, anchored by the Diagnóstico Contassesc — a free fiscal diagnostic tool that analyzes tax efficiency and identifies savings opportunities. On top of the core advisory platform, Contassesc provides two free browser-based calculators: the Simulador de Custo Efetivo de Empregado (calculating real employee cost including employer charges and provisions) and the Simulador Fim da Escala 6×1 (estimating payroll impact of Brazil's proposed work schedule reform). The company also operates a client portal via Onvio, a newsletter service called meConta, and an educational glossary. All services are backed by a team of 300+ professionals managing 3,000+ client companies across 6 physical branches in Santa Catarina.

Direct peers

• Conta Azul: Brazilian SMB financial management SaaS platform providing accounting automation, invoicing and tax tools. Comparable as an enablement layer for SMB accounting needs, often partnered with or competing against traditional accounting firms like Contassesc.
• Agilize Contabilidade Online: Brazilian online accounting firm offering bookkeeping, tax and HR services to SMBs through a SaaS-enabled platform. Comparable in target customer (SMB) and core services (contabilidade, fiscal), competing head-on with Contassesc's mid-tier offerings.
• Contabilizei: Brazil's largest online accounting firm serving SMBs with automated bookkeeping, tax compliance and advisory. Directly comparable as a tax/accounting services provider targeting the same SMB segment, but with a digital-first delivery model versus Contassesc's office-led approach.

Broad incumbents

• Deloitte Brazil: Big Four professional services firm offering tax advisory, audit and consulting in Brazil. Comparable only at the high-end of tax advisory where Contassesc's larger enterprise clients (Grupo Pegoraro, etc.) might also engage Big Four firms.
• Sage Brasil: International accounting and ERP software vendor with a Brazilian operation serving SMBs and mid-market firms. Comparable as an incumbent in the SMB accounting software category that competes indirectly with Contassesc's advisory-driven service.
• TOTVS: Brazil's largest enterprise software company offering ERP, fiscal and accounting modules used by thousands of Brazilian businesses. Comparable as a broad incumbent in the Brazilian accounting/fiscal software category, with indirect competition via client-side automation.
• Senior Sistemas: Brazilian enterprise management software vendor providing ERP, HR and fiscal solutions to mid-market and large companies. Comparable as a technology incumbent whose fiscal/HR modules compete with parts of Contassesc's integrated service offering.

Emerging players

• ContaSimples: Brazilian fintech focused on banking and accounting automation for SMBs and MEI entrepreneurs. Comparable in serving the lower end of the SMB segment with digital-first services; represents a partial overlap with Contassesc's micro/SMB client base.
• eNotas: Brazilian SaaS platform for electronic fiscal document issuance and tax automation. Comparable as a fiscal technology enabler targeting the same SMB ecosystem; represents partial competition for tax compliance services.

Others

• Thomson Reuters (Onvio): Provider of the Onvio client portal that Contassesc uses as its core client-facing platform. Comparable as a critical infrastructure/information vendor; also offers broader tax and accounting software that overlaps functionally with Contassesc's advisory stack.
