Every business needs these systems:

1. Lead generation

2. Qualification

3. Closing.

If it's missing one or more, it won't make money. A fourth system, for Fulfillment, is also a darn good idea.

Many tools are sold as a "business in a box" or a complete solution when in actual fact they are a small piece of just one of these systems. For example, whiteboard explainer videos were all the rage awhile back. People jumped on board because they were told the videos would make sales brainlessly easy. Ha ha, the joke's on them and the only people who made money were the software creators.

Where's the traffic in that situation (leads system)?

Maybe a little qualification in the video, if it's written correctly.

Maybe a little closing (conversion to sale, moving the lead to become a buyer) if the copy is good and the offer is a match to the viewer.

But as a "business in a box"? A complete system? Seriously flawed. Many pieces missing.

You have an idea of your target market. How will you attract them? How will you capture those leads, then nurture them? And after that, what offer will you present them with?

These are the nature of all those mistakes you want to avoid. No one is going to give you this expertise for free. It's earned by the school of hard knocks--they sure didn't teach it to me 20+ years ago in college--and it comes at a price.
