I think that all depends on how you setup your deal pipeline. The way ours is our first deal stage is “Active.” And we define active as a lead has made a request for quote or some sort of communication hinting at a potential need for our services.
In our pipeline it wouldn’t make sense to make a deal for everyone we made at a tradeshow because not everyone is needing our services at that time. But they might later so they are nice to have in the CRM to keep tabs on.
