Vedor name for expen

Hello,

i'm sorry if my question is a duplicate, but i didn't find an answer so .. here my question :)

Now i possible connect the expenses to a Customer and after make an Invoice.
My question is:
is possible connect expenses to a Vendor ?
Because in Italy is need at the end of the year give a list of all customers and all vendors and invoices and expenses
So maybe is possible add a category of user called Vendor where is possible put, name, surname, company TAX ID, Address ecc ecc

any idea about this ?

Thank you very much
