What is a CC-e (Carta de Correção)?

CC-e is a Correction Letter used to fix minor errors in an authorized NF-e, such as typos in the buyer's address or product descriptions. It cannot be used to change values, quantities, or tax rates.

When should I use Inutilização?

Use Inutilização when a range of NF-e numbering has been damaged, lost, or will not be used. This tells the tax authority that those numbers are intentionally skipped.

What is DF-e Distribution?

DF-e Distribution allows you to query all fiscal documents (NF-e, CT-e, etc.) issued against your CNPJ. Use it with the last NSU to retrieve only new documents.

Can I automate my accounting department with this?

Yes! The 'List by Period' and 'Download XML & DANFE' tools allow your AI agent to fetch all invoices from a specific month, download the XMLs, and seamlessly integrate them into accounting workflows.
