Introduction

Brazil has a variety of electronic tax documents that must be issued in different cases for various tax purposes. These include service invoices (NFS-e), product invoices (NF-e), and consumer invoices (NFC-e). Each document type is subject to variations from state to state and municipality to municipality, with each jurisdiction applying its own rules, formats, and APIs for issuing fiscal documents. Invopop’s Documentos Fiscais Eletrônicos app provides a unified way to issue fiscal documents across all Brazilian states and over 2000 municipalities using GOBL. You can find the full list of supported municipalities here. This guide will walk you through the steps required first to register a supplier and then issue electronic fiscal documents in their name.

​
Prerequisites

To issue electronic fiscal documents in Brazil, you will need:
  • Supplier details, including:
    • name,
    • CNPJ (Cadastro Nacional da Pessoa Jurídica),
    • address,
    • municipality code (IBGE),
    • municipal registration number (for NFS-e),
    • state registration number (for NF-e and NFC-e),
    • whether the supplier opts into the Simples Nacional tax regime,
    • whether the supplier benefits from a fiscal incentive, and,
    • optionally, any special tax regime (MEI, estimated, coop…) the supplier is subject to.
  • Customer details (except for NFC-e where the customer is optional).
  • Details of the goods or services provided:
    • quantity,
    • price,
    • applicable tax rates (ISS, ICMS, PIS, COFINS, etc.), and,
    • (only for services) service code (Código Item Lista Serviço) as defined by the municipality.
  • To have chosen an invoice series
  • A certificate and password accepted by the municipality (for NFS-e) or the state (for NF-e and NFC-e) to send electronic fiscal documents in the name of the supplier.

​
Setup

There are four key processes to prepare:
  • connect the Documentos Fiscais Eletrônicos Brazil app,
  • create the supplier registration workflow,
  • configure the supplier post-registration workflow,
  • prepare the invoicing workflows.
These instructions apply to both the sandbox and live environments. Please note that the sandbox environment is simulated, and most responses are mocked. You’ll still need to register suppliers in the sandbox, but the company details, certificates or passwords don’t need to be valid or real.
All of the following steps must be carried out from the Invopop Console.
1

Connect the Documentos Fiscais Eletrônicos Brazil app

Enter the Configuration section, then tap Apps. Tap on the Connect button of the Documentos Fiscais Eletrônicos Brazil app.
DF-e Brazil App
2

Create the supplier registration workflow

Follow one of the methods below and ensure to Save and Publish the workflow:

DF-e register supplier

This workflow will start the registration of a supplier to issue electronic tax documents.
3

Configure the supplier post-registration workflow

Follow one of the methods below and ensure to Save and Publish the workflow:

DF-e process supplier post-registration

This workflow should contain any processing that needs to happen after a supplier completes the registration process.
This workflow will automatically be executed once a supplier completes the registration process. You can customize it to suit your needs (e.g., adding a webhook, or an email notification after a supplier has been registered.)
Now you need to go back to Configuration > Apps, tap the Configure button on the Documentos Fiscais Eletrônicos Brazil app, choose the “Post-registration workflow” we just created and Save the changes.
4

Prepare NFS-e Workflow

You can skip this step if you’re not interested in issuing NFS-e documents.
Follow one of the methods below and ensure to Save and Publish the workflow:

DF-e issue service invoice (NFS-e)

This workflow will issue a service invoice (NFS-e) in Brazil.
5

Prepare NF-e Workflow

You can skip this step if you’re not interested in issuing NF-e documents.
Follow one of the methods below and ensure to Save and Publish the workflow:

DF-e issue product invoice (NF-e)

This workflow will issue a product invoice (NF-e) in Brazil.
6

Prepare NFC-e Workflow

You can skip this step if you’re not interested in issuing NFC-e documents.
Follow one of the methods below and ensure to Save and Publish the workflow:

DF-e issue consumer invoice (NFC-e)

This workflow will issue a customer invoice (NFC-e) in Brazil.
7

Prepare NFS-e Cancel Workflow

You can skip this step if you’re not interested in cancelling NFS-e documents.
Follow one of the methods below and ensure to Save and Publish the workflow:

DF-e cancel service invoice (NFS-e)

This workflow will cancel a previously sent NFS-e invoice in Brazil.
8

Prepare NF-e Cancel Workflow

You can skip this step if you’re not interested in cancelling NF-e documents.
Follow one of the methods below and ensure to Save and Publish the workflow:

DF-e cancel product invoice (NF-e)

This workflow will cancel a previously sent NF-e invoice in Brazil.
9

Prepare NFC-e Cancel Workflow

You can skip this step if you’re not interested in cancelling NFC-e documents.
Follow one of the methods below and ensure to Save and Publish the workflow:

DF-e cancel consumer invoice (NFC-e)

This workflow will cancel a previously sent NFC-e invoice in Brazil.

​
Running

In this section, we’ll provide details on how to first persist and register a supplier, followed by issuing invoices on their behalf. As usual, the recommended approach for running jobs is to perform two steps; first upload the document to the silo, second create a job. All operations described in the following sections can be performed manually via the Invopop Console, or programmatically via the API. The process is essentially the same in both cases, so we’ll demonstrate the manual method for this guide.

​
Register a Supplier

Find the Parties section of the sidebar and click Suppliers. Tap the + New Supplier button to be presented with a new editor. Copy and paste the example provided below (for testing purposes only, in production you’ll need the details of an actual company). The example includes all the fields required to register a supplier for both NF-e/NFC-e and NFS-e issuance.

        "br-ibge-municipality": "3550308",
        "br-nfse-simples": "1"
    }
}
Tap Build, ensure there are no errors, and click Save. We should now see the document. Find and click the Select Workflow button. Select the Register Supplier workflow created during setup, and click Run workflow. The execution should be successful, and the silo entry will now be in the Processing state. Tap the Meta tab to see the registration link:
Supplier Registration Link
You can access the registration link via the API by fetching the silo entry and reading the meta row where the key is set to registration-link.
Tap the registration link. A new browser window will open with a form to upload the supplier’s credentials. Note that this form can be shared directly with the supplier, if necessary.
Supplier Registration Form
The details from this form are sent securely to Invopop’s local partner, PlugNotas, who will use them to authenticate the supplier in the corresponding tax authority. The supplier must ensure that the certificate and password are valid and accepted by the municipality or state where they operate. Once the form is submitted, the supplier will be registered, and the post-registration workflow will be executed, changing the supplier’s state to Registered. From this point on, you can send service invoices on behalf of the supplier.

​
Send Invoices

The following examples are of example GOBL documents you can copy and paste directly into the Invopop Console or store via the API as silo entries. Then, you must run the appropriate issue workflow created during setup — “DF-e issue service invoice (NFS-e)”, “DF-e issue product invoice (NF-e)”, or “DF-e issue consumer invoice (NFC-e)” — over them.
In the sandbox environment, you’ll notice that executing the workflow will always result in the same PDF and XML being attached to the silo entry. These are mock-up files returned by the sandbox environment for testing purposes.In production, the actual XML file sent to the tax authority and the actual PDF generated will be attached to the silo entry.
In this example, we’re issuing a simple service invoice (NFS-e) from a Brazilian supplier to another Brazilian business customer.Notice:
  • we’ve added the br-nfse-v1 addon; this ensures the document will be validated using the NFS-e rules built into the GOBL library,
  • extensions (ext) and identities have been used in multiple locations for fields whose values cannot be determined any other way,
  • ISS percentage is provided explicitly as it varies depending on the municipality and type of service,
  • there are no totals or calculations; all these will be made automatically when uploading, and,
  • make sure to process it with the “DF-e issue service invoice (NFS-e)” workflow created during setup.

In this example, we’re issuing an extended product invoice (NF-e) from a Brazilian supplier to another Brazilian business customer.Notice:
  • we’ve added the br-nfe-v4 addon without the simplified tag; this sets the br-nfe-model extension to 55 (NF-e),
  • the customer is required for NF-e and must include a full address; Brazilian customers must declare the br-ibge-municipality extension and a valid state, while foreign customers can be identified by a country-qualified identity (e.g. a passport) instead of a tax_id,
  • supplier and customer addresses must include a country; it is auto-filled from the party’s tax ID (or first identity that declares a country) when omitted,
  • each line must include a br-nfe-cfop extension to classify the fiscal operation,
  • item identities carry the NCM product classification code (cProd in the NF-e XML) and the GTIN barcode (cEAN),
  • item.ref maps to the supplier’s internal product code, and item.unit is converted to a UNECE unit code,
  • line discounts reduce the taxable base (vDesc); line charges with key delivery map to freight (vFrete) and key insurance to insurance value (vSeg),
  • line.order provides the line reference within the purchase order (nItemPed),
  • a line notes entry with key goods maps to per-item additional information (infAdProd),
  • ordering.code sets the purchase order number (nPed in compra) and ordering.contracts[0].code sets the contract number (nCont),
  • delivery.receiver sets a separate delivery address (entrega) when goods ship to a different location than the buyer’s fiscal address,
  • the payment instructions key is set to credit-transfer, which causes the br-nfe-payment-means extension to be set automatically to 18 (transferência bancária),
  • a general note maps to complementary information (infCpl) in the NF-e XML,
  • tax percentages are provided explicitly as they vary depending on the state and type of goods,
  • there are no totals or calculations; all these will be made automatically when uploading, and,
  • make sure to process it with the “DF-e issue product invoice (NF-e)” workflow created during setup.

In this example, we’re issuing a product invoice (NF-e) from a supplier enrolled in the Simples Nacional tax regime.Notice the differences from the previous example:
  • the supplier declares its regime with the br-nfe-regime extension set to 1 (Simples Nacional); use 2 for Simples Nacional, Excess or 4 for MEI — omitting it defaults to 3 (normal regime),
  • each ICMS line carries the br-nfe-icms-csosn extension (here 101, taxed with credit permission) instead of the br-nfe-icms-cst code that normal-regime issuers use,
  • PIS and COFINS are still required on every line but are not levied per item under Simples Nacional, so they use the br-nfe-pis-cst and br-nfe-cofins-cst extensions set to 49 (other operations) at a 0% rate,
  • there are no totals or calculations; all these will be made automatically when uploading, and,
  • make sure to process it with the “DF-e issue product invoice (NF-e)” workflow created during setup.

In this example, we’re issuing a NF-e that fully returns the goods of a previously issued B2B product invoice — a devolução total under the pre-reform (pre-RTC) rules.Notice the differences from a standard product invoice:
  • the document type is credit-note; it keeps the br-nfe-v4 addon and is still issued as an NF-e, so br-nfe-model is derived as 55,
  • a preceding entry references the original NF-e and carries its SEFAZ access key (chave de acesso) as a stamp — you can copy it from the sefaz-key entry in the stamps array of the original invoice’s envelope head, where it was added once the tax authority authorized the document,
  • because this is a full return, the br-nfe-purpose extension is set to 4 (Goods Return) and the br-nfe-operation-type extension to 0 (Inbound / Entrada), since the returned goods re-enter the supplier; standard invoices set these automatically to 1 (normal) and 1 (outbound), but corrective documents must set both explicitly,
  • no br-nfe-credit-note-type extension is used: that field only applies to post-reform IBS/CBS credit notes (those set br-nfe-purpose to 5),
  • the line br-nfe-cfop is a return code — 2202 (Devolução de venda de mercadoria adquirida ou recebida de terceiros) — mirroring the original 6102 sale but recorded as an inbound inter-state operation (CFOP starting with 2),
  • the payment sets the br-nfe-payment-means extension to 90 (No payment), as a return does not involve a new payment,
  • there are no totals or calculations; all these will be made automatically when uploading, and,
  • make sure to process it with the “DF-e issue product invoice (NF-e)” workflow created during setup.

In this example, we’re issuing a simple consumer invoice (NFC-e) from a Brazilian supplier.Notice:
  • we’ve added the br-nfe-v4 addon with the simplified tag; this sets the br-nfe-model extension to 65 (NFC-e),
  • the customer is optional and in this example we’ve omitted it,
  • extensions (ext) and identities have been used in multiple locations for fields whose values cannot be determined any other way,
  • the payment instructions key is set to card, which causes the br-nfe-payment-means extension to be set automatically to 03 (cartão de crédito),
  • tax percentages are provided explicitly as they vary depending on the state and type of goods,
  • there are no totals or calculations; all these will be made automatically when uploading, and,
  • make sure to process it with the “DF-e issue consumer invoice (NFC-e)” workflow created during setup.

Cancel an invoice

If you need to cancel a document that has already been sent to the tax authority, you can use the cancel workflows created during setup. Run the appropriate cancel workflow — NFS-e, NF-e, or NFC-e — over the silo entry you want to cancel. On success, the entry will be set to Void.
NFS-e cancellations are subject to the rules of each municipality. Some require a specific cancellation code. NFC-e cancellations must be requested within the cancellation window set by the originating state.

​
Configuration

Both cancel actions accept optional parameters that control the cancellation request. They can be set as a default on the workflow step (via the step’s configuration page in the Console) or overridden per job by passing them as arguments when creating the job via the API.
ParameterJob argumentApplies toNotes
Cancellation reasonnfe-br-cancel-reasonNFS-e, NF-e, and NFC-eFree-text reason for the cancellation. For NF-e and NFC-e, must be at least 15 characters if provided. Defaults to the system default when omitted.
Cancellation codenfe-br-cancel-codeNFS-e onlyMunicipality-specific cancellation code, for example 9 for “Outros” in the National NFS-e system. Defaults to the system default when omitted.
Job arguments take precedence over the step configuration. To pass them when creating a job via the API: 
{
  "workflow_id": "...",
  "silo_entry_id": "...",
  "args": {
    "nfe-br-cancel-reason": "Cancelamento a pedido do Prestador",
    "nfe-br-cancel-code": "9"
  }
}

FAQ

Invopop supports NF-e, NFS-e and NFC-e documents. Transport documents (MDF-e and CF-e) are not currently supported.
