Both vendors and buyers want the sales process to move quickly, whether that's due to targets they've set, budgetary cycles, etc. But it is really important to consult everyone who should be bought in before it gets too late.
Sometimes a company trials a software, sees results compared to what they were doing before, but still doesn't convert to a full license only because the team was happy with the old way they did things. Solving business problems isn't always enough because stakeholders need to illicit bravery and curiosity in the face of new changes.
Technology can be successful and solve problems, but it needs people to champion it if you're going to get in a position to see its value. Make sure both parallel stakeholders and potential users understand why the software needs to be adopted.
As an example, a few years ago, Turtl sold to a company and was heading to their office for the first onboarding meeting. After about five minutes, three people stood up and stormed out of the room. It turned out they hadn't been consulted in any way until this point, in fact, our software hadn't even been mentioned to them!
From our side, we didn't know whether they should have been consulted or not, that was our contact's responsibility, but it put everyone in a very difficult and awkward spot, especially given stakeholder seniority and contracts had already been signed. While we were able to get them on board eventually, it slowed everything down by months and wasn't the smoothest of experiences.
