What's the difference between issuing and capture?

Issuing covers documents your company generates: Openi receives the data from your system, sends it to SEFAZ or the municipality and returns the response. Capture covers documents another company issued to your CNPJ: Openi fetches them from official sources, without you asking the supplier for the XML.

Is NFS-e available in my municipality?

NFS-e coverage varies by Brazilian municipality, for both issuing and capture. Look yours up in the municipality list on this page; if it's not there, the team confirms the path in the demo.

What does each CNPJ need?

The digital certificate and the registrations each document requires: state registration for NF-e, NFC-e and NFCom, municipal registration for NFS-e, and the taxpayer security code for NFC-e. Each company is set up once.

Can I run several companies?

Yes. Headquarters, branches and group companies stay separate, each with its own setup, and are tracked in the same view, filtered by company, document type and status.

What happens when an invoice is rejected?

The rejection comes back with the reason given by SEFAZ or the municipality and is delivered to the system that requested the document. Once the data is fixed at the source, the invoice is issued again through the same flow. A rejection creates no document.

How do cancellations and status updates work?

A cancellation is an event sent to the tax authority, within each document's deadline and rules. Until the event is registered, the invoice shows as cancellation requested, not canceled. Authorization, rejection, cancellation and correction letter reach your system with each event.

How does Openi integrate with my ERP?

The ERP or your platform sends the data to issue and gets back the number, protocol, files and status of each document. Received invoices move on to document management and to the ERP. The method for each integration is defined in the technical assessment.

Is Openi ready for Brazil's tax reform?

The new IBS, CBS and Selective Tax groups enter the layouts by technical note, on different schedules for each document, and the validation rules are still being adjusted. In the demo, the team shows what's already updated for the documents you use. Openi doesn't replace your company's tax analysis.

Every issued document is tracked from submission to response, with protocol, time and history. Tax status, integration status and the action needed are shown apart, because they are different things.

Integration statusWhether the response came back and whether it has reached the system that requested the document.

Brazil's tax reform

Get your flows readyfor the new tax documents.

Brazil's consumption tax reform changes what invoices carry before it changes how taxes are calculated. New information groups enter the layouts, validation rules are adjusted by technical note, and every new field has to reach the systems that use it.

01New groups and fieldsIBS, CBS and the Selective Tax (the reform's new taxes) enter the NF-e and NFC-e layouts, with equivalents in other documents according to each one's technical notes.
02Validation rulesRejections tied to the new groups are switched on, postponed or adjusted by technical note version.
03Updates by document and versionEach document changes at its own pace: NF-e, NFC-e, NFS-e, CT-e and NFCom have their own schedules and layouts.
04Data all the way to your systemsA new field only matters if it reaches the ERP, tax and accounting systems that depend on it.

Challenge: Several companies in the group, each sale and service with its own invoice under the right CNPJ, without checking invoice by invoice what was authorized or rejected.
What was built: Each issuer registered once. Issuing is one call, processing is asynchronous and every event reaches the group's system.
Events tracked: Authorization, rejection with the reason, cancellation and correction letter. Documents downloaded one by one or in bulk.
