IT Services and IT Consulting São Paulo, SP 51–200 employees Founded 2010 Partnership

Smart Online operates a SaaS platform connecting sellers, marketplaces, and carriers across Brazil's complex fiscal and logistics landscape. The tech stack reveals a data-engineering–heavy operation: Python + Pandas + Dask + PySpark for document processing, PostgreSQL + MongoDB + ClickHouse for polyglot storage, and Dagster + Airflow for pipeline orchestration. Pain points cluster around scale (5M+ documents/month) and stability, while hiring acceleration in engineering (7 roles) signals an ongoing push to automate tax compliance and document workflows at higher throughput.

About Smart Online

Smart Online is a SaaS platform built to automate fiscal document issuance, tax payment coordination, and logistics management for sellers, marketplaces, and carriers operating in Brazil. The product addresses logistical and fiscal bottlenecks that compound as transaction volume grows—handling responsibilities like CT-e, MDF-e, and DIFAL tax compliance, as well as platform-to-carrier messaging. Founded in 2010 and headquartered in São Paulo, the company operates at scale: processing millions of documents monthly across hundreds of clients. The platform integrates directly with SEFAZ (Brazil's tax authority) and AWS infrastructure to manage both document workflows and tax settlement.
