Invoice

The App consist of maintenance, eventually leading to the creation of a valued note which can be sent by Email.
We should first go to the company section and correctly create a company and its Email.
Once the company is created, customers and their Emails should be created to further sending of the valued notes.
Then we should register the concepts to be treated with their price.
Once the master files have been created valued notes can be registered and sent by Email.
Now we can consult valued notes between dates, note to note, by customer or all together.
There're other options, shown in the attached menus.
Each section has its own help.
