Online MDF-e issuer — built from the trip’s CT-es
Generate the electronic manifest (MDF-e) per trip, automatically grouping the CT-es and invoices. Controlled closing, CIOT integration.
The MDF-e (Manifesto Eletrônico de Documentos Fiscais) is Brazil’s electronic manifest that declares, per vehicle and per trip, every CT-e and invoice traveling in the same transport operation. Unlike the CT-e (issued per load), the MDF-e is issued per trip — it groups the documents inside the truck and accompanies the vehicle on the road, subject to tax-authority inspection. In BrainCargo, the MDF-e is built automatically from the CT-es already issued for the trip, with no re-keying. It includes closing control at the end of the route (essential to avoid blocking future issuances), support for multiple vehicles, and native integration with the operation’s CIOT.
BrainCargo’s MDF-e issuer eliminates re-keying: the trip already has issued CT-es, and the MDF-e is built from them in a few clicks. Closing, cancellation and contingency all live in the same dashboard.
Why this module
Zero re-keying
The MDF-e is generated from the trip’s already-issued CT-es — no rework, no mismatch between documents.
Closing under control
The dashboard tracks every open MDF-e and reminds you to close it — avoiding tax-authority blocks on future issuances.
Linked to the CIOT
The trip’s CIOT is tied to the matching MDF-e, satisfying the regulator’s requirement in a single flow.

Frequently asked questions
What’s the difference between CT-e and MDF-e?
The CT-e is issued per load provided (freight operation). The MDF-e is issued per trip, grouping all the CT-es and invoices traveling in the same vehicle on the same trip.
How is the MDF-e built in BrainCargo?
Automatically: when the trip starts, the system groups the CT-es already issued for those vehicles and generates the matching MDF-e, with up-front validation before sending to the tax authority.
What happens if I forget to close an MDF-e?
The tax authority can block new issuances from the same issuer until the open MDF-e is closed. BrainCargo flags MDF-es pending closure and lets you close them in bulk.
What about trips with a vehicle change?
The MDF-e supports multiple vehicles and updates during the trip. For specific swap cases, the dashboard guides the proper record.
Is there a free plan for MDF-e?
Yes. The Free plan includes the MDF-e: up to 10 monthly issuances across CT-e and MDF-e (combined), with 1 company tax ID.
