La palabra del día: Factura

Feminine noun. Account in which items sold or services performed are detailed with their price and delivered to the customer to demand payment. E.g.: La factura en este caso se basará en los precios ofrecidos por el proveedor : The Invoice will therefore be based on prices offered by our supplier.
The verb is facturar.
By the way, in Argentina, una factura is also a specific kind of pastry very good for breakfast with mate, and facturar is the whole process of making hams, sausages and other cold cuts out of a pork. I also remember vividly that my mother used to call facura a bad spell, but I haven’t found that meaning in the RAE. dc
