I'd stick to the basics when cold calling. What does the client want or need in the forseeable future? When are they likely to be making a purchasing decision? Who do you contact in future and how are you going to contact them?

As Adrain says, there is a hangover period when it comes to end of financial year, not least of which is provisional tax payments. The new annual budget might be there*, but that doesn't mean the cashflow is up to taking the hit just yet.

*in most cases it might be another month or two before capital budgets are really looked at. Also not all companies have 28 Feb as their end of financial year.
