< / > About NFCom

Entendendo a NFCom

NFCom is the digital document that formalizes the provision of communication services, telephony, internet, pay TV, and other media. For any software serving telecom operators, ISPs, or regional providers, correct NFCom issuance is mandatory.

TecnoSpeed's solution helps you structure the XML, handle signing, and print the DANFCom, keeping your team focused on business logic rather than telecom tax specifics.

Most common questions

Frequently Asked Questions

NFCom (Communication Service Electronic Invoice) is the mandatory tax document for companies providing communication services — telephony, internet, pay TV, and similar services. It formalizes the service provision, details the fees charged and applicable taxes, and serves as an official receipt for both the customer and the tax authority.

O Component (DLL/OCX) runs directly within the application's environment, supporting Delphi, C#, and VB6—ideal for developers who prefer handling the messaging process locally. The REST API (PlugNotas) is designed for systems built in PHP, C#, Java, or Python, featuring JSON integration that abstracts tax rules and XSD schemas. Transmission via PlugNotas is asynchronous, returning an ID and status updates via query or webhook.

Technically, it is possible to issue NFCom outside of your software, but this creates real friction for the end user: they have to leave your system, enter data into another tool, and then manually reconcile the information. Integrating NFCom directly into your ERP's workflow eliminates this redundant work, keeps billing data centralized in a single place, and strengthens your software's position as a complete solution for communication service providers.
