In every sales-led company quarter end is a shitshow. It'll be even worse if there's only one chance to bring the numbers back in instead of 2 or 3. It's used to put pressure on sales teams, but the net result over the year is never good because it sours relationships and reduces overall deal value.

The best thing would be continuous daily or weekly reporting with no defined year end. Unfortunately the entire global system of tax and accounting is set up around annual reporting, so change is impossible.
