A conditional guarantee is a guarantee that requires the customer to meet specific terms and conditions to qualify. These guarantees are often framed as “better than money back” (126) and are tied to the key actions a client must take to succeed (e.g., attending sessions, completing modules). The required conditions typically correspond to the actions the customer must complete to remain eligible for the guarantee.

Divergent thinking is a creative problem-solving process that involves generating many possible solutions to a single problem rather than converging on one correct answer. During offer creation, the author instructs entrepreneurs to list every possible way a customer’s problem could be solved before narrowing those possibilities to a specific deliverable.

The “Grand Slam offer” is an offer combining an attractive promotion, a high-value proposition, a premium price, an unbeatable guarantee, and favorable payment terms in a configuration that competitors cannot easily replicate or match on price. Because the offer has no direct equivalent, the author describes it as selling in a “category of one” (26).

Lifetime value is the gross profit accrued over the entire lifetime of a customer. The author defines this specifically as the gross profit per purchase multiplied by the total number of purchases, excluding indirect costs like administrative overhead or rent. Unlike definitions based on total revenue, this calculation focuses on gross profit.

A five-part framework for naming an offer to maximize its appeal to a target audience, the M-A-G-I-C Headline Formula stands for: make a magnetic reason why, announce your target customer (avatar), give them a goal, indicate a time interval, and complete with a container word—a word that packages the offer as a named product (e.g., program, system, bootcamp). The resulting name is intended to make the offer more specific and distinctive.

Niche slap is a term coined by the author to describe the mistake of jumping between different market niches too quickly without committing to one long enough to succeed. According to the author, the problem is usually a weak offer rather than a bad market.

Price to value discrepancy is the gap between what a customer pays for an item (price) and what they believe that item is worth (value). People buy when the perceived value far exceeds the price. In the book, a Grand Slam Offer increases perceived value to widen this gap.

The sales-to-fulfillment continuum is a framework illustrating the trade-off between an offer’s ease of sale and its ease of delivery. Offers that are easy to sell (e.g., fully “done-for-you” services) are often hard to fulfill, while offers that are easy to fulfill (e.g., “do-it-yourself” products) are typically harder to sell. The framework helps businesses balance these competing considerations.

The “starving crowd” is a metaphor for a market with massive, pre-existing, and urgent demand for a solution. According to the author, this level of demand outweighs every other business variable, allowing even a mediocre offer to succeed.

The value equation is the author’s formula for calculating the perceived value of any offer: (dream outcome × perceived likelihood of achievement) ÷ (time delay × effort and sacrifice). The equation combines the desired outcome, the customer’s confidence in achieving it, the time required, and the effort and sacrifice involved to determine perceived value.
