NFER Emissor Fiscal

NFER Emissor Fiscal seamlessly connects your WooCommerce store to the NFER fiscal intelligence cloud platform (nfer.me). Engineered under rigorous software standards and fully compatible with WooCommerce HPOS (High-Performance Order Storage), the plugin eliminates complex manual REST API setups and unifies billing for physical products, digital goods, courses, services, and subscription clubs.

NF-e – Product Invoices (Model 55)

• 100% Automated SEFAZ Flow: Transmission, protocol query, DANFE (PDF) and authorized XML handled end to end by the NFER Cloud Engine.
• Complete Tax Engine: ICMS, ICMS-ST (MVA), IPI, PIS/COFINS and CFOP routing, with automatic Reforma Tributária (IBS/CBS — LC 214/2025) support.
• E-book Immunity: Digital books (NCM 4901) issued with constitutional ICMS immunity (Art. 150 CF), even when set as Virtual in WooCommerce.
• Contingency Ready: Automatic SVC-AN / SVC-RS handling whenever SEFAZ goes offline.

NFS-e – Service Invoices (National Standard)

NFER is connected to the National Data Environment (ADN / Serpro) and to municipal tax authorities, in compliance with Resolução CGSN nº 191/2026:

• Full National Coverage: Since November 1st, 2026, all 5,570+ Brazilian municipalities are enabled for the National NFS-e standard for Simples Nacional (ME and EPP) and MEI companies.
• Broad Regime Support: Lucro Presumido and Lucro Real companies issue through unified DPS emission and integrated municipal webservices.
• Standardized Fields: National Tax Code (cTribNac), itemized service descriptions, and municipal tax withholdings.

Automated Cancellation & Smart Return (Devolução)

• Status-triggered Cancellation: When an order is changed to Cancelled or Refunded in WooCommerce, the plugin automatically requests invoice cancellation via NFER.
• 24-Hour SEFAZ Smart Window:
  • If the NF-e was authorized within the last 24 hours, an automated cancellation event (Evento 110111) is transmitted directly to SEFAZ.
  • If the legal 24-hour deadline has expired, NFER automatically issues a Return / Reversal NF-e (CFOP 1202) referencing the original invoice key, avoiding tax penalties and reversing ICMS/PIS/COFINS.
• Manual Cancellation on Order Screen: Admin button in order metabox with mandatory audited justification (15+ characters).

Fiscal Intelligence for B2B and B2C Sales

NFER automates Brazilian tax compliance complexities:

• B2C Operations (Final Consumer): Consumer sales with automated Final Consumer flag (indFinal = 1).
• B2B Operations (Interstate CNPJ to CNPJ): Corporate sales for resale or industrial manufacturing (indFinal = 0), handling DIFAL exemptions and applying Tax Substitution rules (ICMS-ST / MVA) and State Registration (IE) status.
• Interstate DIFAL Sharing (EC 87/2015): Automatic calculation of interstate tax differentials without maintaining manual tax tables.
• Broad Tax Regime Compatibility: Supports companies under Simples Nacional (CSOSN), Lucro Presumido, and Lucro Real (CST).

Key Features

• Digital E-books Intelligence (NCM 4901): Automatic recognition of digital books with NF-e (Model 55) emission under constitutional ICMS tax immunity (Art. 150 CF), even when set as Virtual in WooCommerce.
• Hybrid Fiscal Split: Dual simultaneous billing for a single order (e.g. 60% NF-e Merchandise/E-book + 40% NFS-e Service/Course), enabling legal tax optimization for digital creators.
• Fiscal Data Product Tab: NCM (8 digits), CEST (7 digits), Merchandise Fiscal Origin (0 to 8), Standardized Unit of Measurement (UN, PC, KG, etc.), and SPED Item Type. Supports simple and variable products with parent fallback.
• Complete Brazilian Checkout Fields: Injects CPF, CNPJ, Company Name (Razão Social), State Registration (Inscrição Estadual with Isento toggle), Address Number, and Neighborhood with dynamic input masks.
• B2B Purchase Purpose Dropdown: Lets corporate buyers select whether the purchase is for End Consumption, Resale, or Industrialization.
• Compatibility with Brazilian Market Plugins: Works out-of-the-box independently or seamlessly alongside Brazilian Market on WooCommerce (Claudio Sanches) without duplicating fields.
• One-Click or 100% Automated Emission: Configure automatic emission upon payment confirmation or issue manually via order actions or quick modal.
• Instant Access to DANFE, NFS-e PDF & XML: Direct buttons to download DANFE PDF and authorized XML from the WooCommerce order list and order screens in the admin.
