HW Sistemas builds and supports end-to-end management software for Brazilian businesses — from inventory control and electronic invoicing to full ERP solutions. Trusted by hundreds of companies since 1999.
From the sales counter to the boardroom, our modular platform covers every operational need — and grows with you as your business scales.
Our most comprehensive release yet: a fully integrated enterprise resource planning platform with AI agent capabilities, real-time dashboards, and deep fiscal compliance built in from the ground up. Designed for businesses ready to operate at scale.
Real-time visibility across multiple warehouses, automatic reorder triggers, batch and serial number tracking, and full purchase-to-sale traceability.
Certified electronic invoice generation for goods (NF-e) and services (NFS-e), with automatic SEFAZ communication, XML storage, and DANFE printing.
Automated generation of SPED Fiscal, SPED Contábil, and EFD-ICMS/IPI files — keeping your company permanently compliant with Brazilian federal and state tax authorities.
SEFAZ-certified fiscal coupon management for retail environments, with cashier control, TEF integration, and operator-level access permissions.
A unified operations hub — receivables, payables, cost centers, cash flow projections, and executive reports — so decision-makers always have the full picture.
HW Sistemas was born in Governador Valadares in 1999 with a clear conviction: technology should empower entrepreneurs, not overwhelm them. Over two decades later, that principle still shapes every product we ship and every support call we take.
We believe businesses thrive when they operate with clarity. Our software brings transparency to every transaction, report, and fiscal obligation.
Brazilian fiscal legislation is among the world's most complex. Our team has navigated every reform since 1999 — that institutional memory is your competitive advantage.
From PAF-ECF to AI-powered assistants, we adopt new technology deliberately — integrating it seamlessly into workflows your team already knows.
Plenty of vendors sell software. Very few have been in the room with your industry for 25 years, iterating through every tax reform, every technological shift.
Brazilian tax rules change constantly. Our dedicated compliance team monitors SEFAZ, Receita Federal, and IBGE releases continuously — your software is always current, without any action on your part.
You speak to engineers, not chatbots. Our support lines are staffed Monday through Friday 08:00–18:00 and Saturday mornings. Critical issues are escalated through a named on-call rotation.
Start with exactly what you need — a single module for invoicing, or stock control alone. Add capabilities as you grow. No forced bundles, no licensing bloat.
All client data is stored in auditable formats you can export at any time. Vendor lock-in is not our business model — long-term trust is.
Retail, services, manufacturing, distribution — each vertical has its own fiscal and operational quirks. Our platform ships with pre-configured profiles tested in real-world environments.
Our upcoming ERP release includes a native AI agent layer — automating repetitive tasks, flagging anomalies in financial data, and generating plain-language reports from complex datasets.
Our most ambitious product release is on the horizon. The HW ERP integrates an AI assistant that reads your operational data, surfaces insights, and automates routine fiscal tasks — designed specifically for the Brazilian regulatory environment.
Our offices and support lines will observe adjusted hours during the Corpus Christi public holiday. Emergency on-call support remains available via our dedicated plantão line throughout the period.
In observance of Dia do Trabalhador (Labour Day, 1 May), HW Sistemas will be closed. Regular business hours resume the following day. Planned support requests should be submitted before the holiday where possible.
We've answered these many times over 25 years. If something isn't covered below, our team is a message away.
