Why “one-size-fits-all” sales tactics are costing you big

If McDonald’s ran your sales team, every rep would flip the sales conversation the exact same way—just like burgers.

And honestly, that’s how a lot of companies do sell.

They find one “proven” method and then teach everyone to use it, word for word, script for script. No deviation. No nuance. Just “this is the way.”

But here’s the kicker: when we follow a single sales method, we risk alienating 75% of our potential buyers.

Yep—three out of four people walk away… not because they didn’t need what you offer, but because you didn’t speak their language.

Here’s what I mean:

Each buyer processes the world differently, and DISC helps us decode that.

• The Trusted Advisor model? Great for highly analytical buyers (about 12% of people—DISC type C).

• The Challenger Sale? Works like a charm on results-focused, ROI-driven types (18%—DISC D).

• Emotional storytelling? That lights up the experiential, high-energy crowd (36%—DISC I).

• Relationship-first selling? It’s gold for safety- and trust-oriented folks (34%—DISC S).

Now, if you’re using only one of these methods, you’re missing out on the other 3. That’s a LOT of untapped opportunity.

Most salespeople hover around a 20% closing ratio. Why?

Because they keep selling one way...

But when they adapt their communication to match the buyer’s DISC type?

We’ve seen that number jump to 60%, 75%… even 95%.

The key is learning how to recognize who’s in front of you—and shift your approach accordingly.

That’s exactly what I unpack inside my course, Communication Mastery.
But more on that later.

For now, just ask yourself:

Am I selling the way I like to buy… or the way they need to hear it?

Big difference.
