The following is more of a disclaimer: marketing is not the answer. Inbound marketing is not the answer. Focusing on marketing is always going to be the easy answer. I know, it's says "Mahoney Internet Marketing" on the door. But think about it.
Joke: Why do some marketers become marketers?
Punchline: Because they can't sell.
Admittedly, the word 'smarketing' is a marketing term. But don't miss this;
But call a marketer at month end? You'll probably catch them planning Feb, March and April content. At least they should. Call a sales person at month end? Good luck.
If you are in sales (and if you are an entrepreneur, CEO, customer service, HR, whatever role, you are in sales) you know it is month end. You are probably looking at the clock, either in anticipation or anxiety. If in anticipation, you are looking forward to a celebration. If anxiety, well, no need to say it, it's month's end.
Turn off your happy ears. How committed are they? To do what is necessary? To commit resources to the next step? Whether that is in the decision making or buying process. Push back. Disqualify. Politely call out the pink elephant in the room; their objections, challenges and disbeliefs.
Ask, listen and be patient. How compelling are their reasons to change something? If they are not ready, and you push, you might not just lose them this month- you might lose them this quarter. If you don't find a compelling reason to take the next step, you won't get there.
Pay attention! If you understand and get to compelling, what their commitment to that is, you can close month end AND still make it a good solid customer evangelistic sale.
