It is all a disaster because politicians do not understand computers (programming), at the end of last year they made here (Spain) a change by which a VAT rate became 3 decimals, we had to spend "Christmas Eve" and "Christmas" programming everything and preparing the shipments of everything with the servers of the Treasury (government). But the government software was not prepared for 3 decimals, they changed everything back to 2 decimals, so we had to spend "new year's eve" and "new year" undoing everything we had done.
With the added problem that the 3 decimal place invoice submissions during that week did not add up, resulting in piles of invoices from thousands of companies, I don't know how they will fix this without fining the companies for not adding up.
In another thread in this forum someone complains that a QR code must be included in the invoices and that many companies have dot matrix printers, do those who have created this law have any idea of what a dot matrix printer is?
And so on all the time, besides here in Spain we have 17 autonomies (regions) and each one has its different system, so it is not the same invoice management if you are in Bilbao, Barcelona, Malaga, Madrid or Tenerife.
In short, a total disaster.
I just hope to win the lottery soon and retire
