Inventory Control & Stock Management
Knowing exactly what you have, where it is, and when to reorder is the backbone of any profitable operation. Our inventory module delivers granular, real-time visibility across unlimited product categories, suppliers, and storage locations — eliminating the guesswork that quietly erodes margins.
What's Included
- Automatic stock-level alerts and minimum-quantity triggers to prevent out-of-stock events
- Multi-location warehouse tracking with location-based lot and serial-number control
- Full purchase-order lifecycle: from requisition and supplier quotation to goods receipt
- Product cost history and average-cost recalculation on every movement
- Consolidated inventory reports by category, supplier, period, or custom filter
- Barcode and label printing integrated directly with receiving workflows
- Returns management and stock adjustment audit trail for compliance
Companies that migrate to our inventory module typically cut stock discrepancies by over 60% within the first quarter and reclaim hours previously spent on manual reconciliation every week.
Electronic Invoice Issuance — NF-e & NFS-e
Issuing fiscal documents correctly and on time is a legal obligation — but it doesn't have to be a burden. HW Sistemas automates the entire electronic invoice lifecycle, from XML generation and digital signature to transmission to SEFAZ (the Brazilian tax authority) and automatic storage for the mandatory five-year retention period.
What's Included
- NF-e (Nota Fiscal Eletrônica) issuance for product sales, with automatic DANFE generation and email delivery to recipients
- NFS-e (Nota Fiscal de Serviços Eletrônica) integrated with the municipal systems of the operating municipality
- Automatic XML transmission to SEFAZ with real-time authorization status feedback
- Contingency mode — offline issuance that synchronizes the moment connectivity is restored
- Cancellation, correction letter (CC-e), and XML manifest workflows fully managed within the system
- Secure XML repository with easy retrieval for audits, accountants, and fiscal reviews
- Tax rate tables maintained and updated by HW Sistemas as legislation changes
Automated invoice issuance eliminates manual keying errors, reduces rejection rates at SEFAZ, and ensures your business is always audit-ready — without dedicating a dedicated fiscal team to the task.
Automation
SPED — Brazilian Public Digital Bookkeeping
The Sistema Público de Escrituração Digital (SPED) requires businesses to transmit structured accounting and fiscal records electronically to federal authorities. Our SPED module generates, validates, and delivers these files automatically — built directly on top of your everyday transactional data so there's no manual re-entry.
What's Included
- SPED Fiscal (EFD-ICMS/IPI) — digital tax bookkeeping for state and federal goods taxes
- SPED Contribuições (EFD-Contribuições) — PIS and COFINS structured record generation
- Built-in validation engine that flags inconsistencies before transmission, preventing penalties
- Automatic registry block construction from live sales, purchase, and inventory data
- Transmission log history with confirmation codes for every successfully sent file
- Accountant-friendly export mode: share SPED files directly with your external accounting firm
What previously required days of manual data gathering and accountant intervention is reduced to a scheduled, automated process — dramatically lowering the risk of fines for late or incorrect SPED submissions.
Record Generation
PAF-ECF — Fiscal Front-End for Point of Sale
For businesses that operate with fiscal receipt printers (ECF), Brazilian legislation requires the use of a certified PAF-ECF (Programa Aplicativo Fiscal — Emissor de Cupom Fiscal) application. HW Sistemas delivers a compliant, fast, and operator-friendly PAF-ECF solution that meets SEFAZ certification requirements while keeping the checkout experience smooth and error-free.
What's Included
- SEFAZ-certified PAF-ECF integration with all major fiscal printer brands
- Operator screens designed for speed — rapid product lookup, quantity entry, and payment processing
- Multiple payment method support: cash, card, voucher, mixed tender
- Automatic reduction Z and fiscal memory reporting in compliance with state requirements
- Customer discount policies and loyalty price rules configurable per operator or register
- Full synchronization with the inventory module — every sale updates stock immediately
- Shift opening/closing controls with operator cash-count reconciliation
Retail and service businesses using our PAF-ECF module stay permanently on the right side of state fiscal legislation while their sales staff spend less time troubleshooting and more time serving customers.
Compliance
Business Manager — Integrated Operational Control
Running a company means tracking many moving parts simultaneously: purchases, sales, receivables, payables, and staff performance. The HW Sistemas Business Manager (Gestor) brings all of these into a single, coherent operational view — giving owners and managers the clarity they need to make better decisions faster.
What's Included
- Sales order management — from quotation to confirmed order to dispatch and invoicing in one workflow
- Purchasing and supplier management with price history comparison and preferred-supplier rules
- Accounts receivable and payable: installment control, due-date alerts, and aging summaries
- Cash flow projection based on real open receivables and scheduled obligations
- Customer and supplier registry with full transaction history and credit limit management
- Customizable management reports: revenue by period, top products, margin analysis, and more
- Multi-user access with role-based permission levels per department or function
- Integration layer connecting every module — inventory, fiscal, and financial data flow without duplication
Business owners who adopt the Gestor module report spending significantly less time chasing down figures from disparate spreadsheets and more time acting on reliable, centralized business intelligence.

Support that's there when you need it most
Software is only as valuable as the help you get when something unexpected happens. Our multi-tier support structure ensures that no matter when an issue arises, you have a clear, reliable path to resolution.
Helpdesk Support
Our primary support channel for operational questions, configuration guidance, and software troubleshooting. Staffed by product-trained technicians who know HW Sistemas inside and out.
Saturday Morning Support
For businesses that operate on weekends, our Saturday support window keeps you covered during one of the busiest retail days of the week — no waiting until Monday to resolve a critical issue.
Emergency On-Call Line
When an issue simply cannot wait — a system-down scenario on a critical trade day, for example — our emergency line connects you directly to a technician outside normal business hours.
Scheduled On-Site Visits
Some situations call for a technician in the room. We offer scheduled on-site visits for implementation, major upgrades, hardware integration, and training sessions tailored to your team's needs.
25 years of refinement you don't start from scratch with
Every feature we ship has been shaped by real feedback from real businesses operating in a demanding fiscal and regulatory environment.
Years of Continuous Development
Founded in 1999, our software has been tested, iterated, and battle-hardened across more than two decades of Brazilian tax law changes, technology shifts, and client growth cycles.
Zero Compliance Guesswork
We monitor federal and state fiscal regulation changes as they happen and push updates to our clients — so you're never caught off-guard by a new SPED layout version or NF-e schema revision.
Single Point of Accountability
Every module — inventory, fiscal, POS, financial — comes from the same team. When you call support, you reach people who understand the full system, not just an isolated component.
Investing in What's Next
While we support the systems businesses rely on today, we're actively building the AI-powered ERP platform that will carry our clients confidently into the next era of business management.
