Pre and immediately post Christmas are the times when businesses tend to go to the wall, sadly. With Christmas being the saviour of many a terrible trading year; cashflow being critical for the survival of every type of business; and the business world always able to spot a business in trouble... you have a perfect recipe for disaster. You need a big investment in stock to do well at Christmas, which ties up your money thereby reducing your cashflow until you sell that stock (which is why Q were flogging the Elemis TSV so long and hard in advance of the TSV day). Lines of credit die up when the difficulties aren't fully known, and worse, suppliers won't release the stock you order without payment up front... that's before the rug gets pulled up from under the business by the main creditors like the banks.
