Should a potential name be the company name or the deal name?

Should a potential name be the company name or the deal name?

We write custom software and can write multiple things for a single client.

If I have an account for 'Client' and they are interested in having 'Application' developed do I set the potential name to 'Client' or 'Application'?

Or something else? A combination of the 2?

What do others do?
