Take the deals pending a March 31 signoff and call those vendors. Let's talk in April. The more a vendor pushes back, the more sure you can be that this deal may be better for the vendor than it is for you. Deals made in the last two hours of the quarter are just plain bad all around. They are bad for the vendor because less revenue means less ability to innovate.
Less revenue means lower levels of support and service.
Less revenue means lower profitability. These deals are bad for you. No user wants to get stuck with an IT plan built on the back of a vendor that isn't growing and innovating, or, worse yet, is going out of business.
