Hello,

First, I would like to congratulate this idea of project! Nice!

I would like suggest add the function of electronic invoice.

Based on the 44-character code of an electronic key, to create one function to idnetify the type of document, for example:

Hello @svjr. I'm happy with your feedback, thanks!

About your idea, I really don't know what is it, I'm tried to read and I didn't understand to much... Can you explain your idea to us? I think that we can discuss and do something from that.

Hello hyanmandian!

So, in Brazil I fear the electronic invoice composed of 44 characters. There is a rule for the formation of each part of this character set.
See the example:

51080701212344000127550010000000981364112281
(02 digits) *** State code (UF) of the issuer
(04 digits) *** Year and month of issue of the NF-e (in AAMM format)
(14 digits) *** CNPJ of the NF-e issuer (CNPJ of your company)
(02 digits) *** NF-e model
(03 digits) *** NF-e series
(09 digits) *** NF-e number
(09 digits) *** NF-e code - Number generated by the system
(01 digits) *** Checksum - DV (Calculation in module 11).

My initial suggestion was to create features that could read and extract this information.

There are numerous types of electronic invoices, see:

Electronic Invoice (NFe) - model 55
Electronic Consumer Invoice (NFCe) - model 65
Electronic Bill of Lading (CTe) - model 57
Electronic Manifesto of Tax Documents (MDFe) - model 58

Here are some links that explain it a little better:
