The issue here is quite simple. If, as a critical IT supplier to a business that suddenly goes down the pan into Administration, I am likely to have within my terms and conditions of supply a clause which will state that in the event of Insolvency or implied insolvency, I have a right to immediately cease supply.
If an Administrator wishes me to continue delivery in order that he (the Administrator), can maximise any recovery to fill his pockets and pay secured creditors, then he will have to put his hand into his own pocket and guarantee me payment for any ongoing supply. I may still be peeved that debt owed prior to Administration may not be paid and feel angry enough to stick two fingers up at any guaranteed future payment unless I can increase the charge to account for this.
I'm all for business recovery and continuity but there comes a point where the playing field has to be level and fair.
