Invoices types

Hi People, i'm new in frontaccounting so i was searching about an option but i can't find it.

I'm from Argentina and here we have 3 or more types of invoices that affect directly to the taxes. If we go to sell a product or service and the company is legally registered we give the client an invoice depending his legal status.

For example:

If the customer is final (thats mean that customer is not suscribed to treasury we give him an Invoice type B)
If the customer is suscribed to treasury and is responsible registered we must to discriminate the VAT or the other taxes.

That is not much problem with sales, because i can see that frontaccounting can make a report of VAT and taxes of global sales in a period to know if you must to pay or not VAT to the treasury. The problem is when you must to load the invoice of the providers that can be an A invoice (with VAT and other taxes), or can be a B or C invoice, that are not discrimanated of taxes but can be deduced of the tax called PROFITS (that here is 35%).

I hope that my bad english allows you to help me in the setup of this.

Best regards and thank you very much!.
