< / > The problem

Issuing the first invoice is 10% of the work. The other 90% are as follows:

Every sprint spent on tax maintenance is a sprint that wasn't on your product.
01

The Maze of City Halls

Each municipality has its own NFS-e standard: ABRASF, DSF, proprietary systems. Any change in the city hall breaks the integration., leaving your team with another urgent headache to solve alone.

02

XML, schemas, and digital signatures

SEFAZ validations, state-specific layouts, tax calculations, A1 certificate signing. This isn't fiscal, it's infrastructure that drains sprints.

03

The Tax Reform has already arrived

IBS, CBS, national NFS-e, new NF-e and NFC-e layouts. The changes are continuous and directly impact the documents your software issues.

04

A1 certificate expires and nobody warns

Each CNPJ has a .PFX or .P12 with an expiration date. When it expires without notice, issuance stops. Manual expiration management does not scale.

05

Physical POS cannot stop

When SEFAZ goes down or the internet fails, retail grinds to a halt. NFC-e in offline contingency requires a specific architecture that custom modules generally lack.

06

Invoices issued to your CNPJ arrive without recipient manifest.

Notes issued against your client's CNPJ require operation acknowledgment and XML download. Manually managing NSU is fragile, slow, and creates tax liability.

< / > The solution

Your application sends a business JSON. PlugNotas handles the rest.

No XML. No direct SEFAZ integrations. Low layout maintenance. You describe the business operation; the API assembles, signs, transmits, and sends notifications. mount, signs, transmit and notification.
End-to-end flow 4 stages · asynchronous cycle
  1. 01

    Your application sends the JSON

    Sales or service data.

  2. 02

    PlugNotas processes

    Searches for the company's registration, defines numbering, calculates taxes, and builds the XML signed with the digital certificate.

  3. Transmission to SEFAZ or City Hall

    The API transmits the document and tracks the processing. You receive the note ID immediately; the final status arrives via webhook.

  4. 04

    Authorized note - you are notified

    Webhook triggers with final status (COMPLETED, REJECTED, or CANCELED). DANFE/RPS PDF and XML available via GET route.

Asynchronous emission. The immediate return is the note ID and the protocol. Use a webhook to receive the final result or check the status whenever you want.

Resources

Built for software houses. Infrastructure for those who issue at scale.

Environments

Instant sandbox

Public sandbox with fixed token for testing without registration. Staging and production on the same endpoint, with environment switching via company configuration.

Reliability

IdIntegration as a solution for idempotency

Your system generates a unique identifier for each note. If the request fails and is re-sent, PlugNotas ensures the document is processed strictly once.

Scale

Asynchronous batch emission

Send arrays of notes in a single HTTP request. The API queues processing and responds immediately.

Real time

Webhook with automatic retries

Each fiscal event triggers a notification to your endpoint. If the receiving server fails, PlugNotas automatically attempts redelivery before closing the cycle.

e-invoice

DF-e management without NSU management

PlugNotas automatically controls the Unique Sequential Number. You activate the query and receive the assigned notes at the webhook.

Reform

National Standard NFS-e

Native compatibility, including IBS and CBS fields. To activate, simply enable the national standard in the company's registration.

Availability

Offline contingency for NFC-e

The NeverStop module issues NFC-e without internet and with the SEFAZ unavailable. When the connection returns, the notes are automatically transmitted and regularized.

< / > Tax Reform

The Tax Reform already impacts the documents your software issues.

IBS, CBS, and NFS-e Nacional: the changes are continuous and mandatory. Software houses that rely on their own modules allocate constant engineering resources. With PlugNotas, you focus on your core business.

Frequently Asked Questions about PlugNotas

PlugNotas is a REST API for tax invoice issuance from TecnoSpeed. It allows software companies to integrate the issuance of NF-e, NFC-e, NFS-e, NFCom, and MDF-e into their systems without having to deal with XML, SEFAZ schemas, municipal requirements, or layout updates. Your application sends the transaction data in JSON; PlugNotas handles assembling the document, signing it, transmitting it, and notifying you of the result.
