Often, you will not even have an opportunity to discuss the solution and payment option details with many of those individuals.
Therefore, the monthly payment options proposal (ESPECIALLY Shield) needs to be provided in a fashion that helps it stand alone and clearly convey what the payment options are designed to do. A number alone does not do that for Shield and, in fact, will create confusion, meaningless comparisons, and noise for the customer and your sales efforts.
The number by itself has little to no value to any audience and it removes all elements of differentiation that could help set you apart from competitors. The accompanying language reviews and re-enforces the dialogue of the sales process, highlights differentiators, includes a financial comparative analysis, and creates a multi-faceted approach to creating value for the customer and you.
Showing only a monthly payment alone, at best, puts you in the herd with your competitors, but, at worst, it confuses customers when they have no opportunity to understand what Shield is and whether or not it can be meaningful.
