We need both sequences in Spain as it is a legal requirement [1]. Yet, it should not be all that difficult to choose the sequence depending on the sign of the invoice. > So what do you think? It has some advantages and simplifies things. Specially makes supporting the negative quantities/amounts from sales much simpler.
