Strengths:

• Gives a sense of freedom of choice while steering the decision.
• Increases perceived value by presenting several successive options.

Weaknesses:

• If the gaps between the options are too obvious, the other party may see through the manipulation.
• There is a risk that the customer opts for the least advantageous option.

When you want to steer a choice without imposing it head-on.
When the other party is hesitating and several levels of proposal can influence their decision.

Although both techniques rest on the idea of a progression in choice or perceived value, they differ in their application and in their psychological impact on the other party.

The tiered offer presents several options from the outset, leaving the other party to choose the one that seems most suitable. It plays on the comparison effect, highlighting different proposals that vary in terms of price, services or benefits. Its aim is to create a perceived move up-market, while preserving a sense of freedom of choice.

The staircase offer, by contrast, works in a progressive way. Rather than presenting every option at once, you start with a base offer and then add successive improvements that make the final option more attractive. This approach exploits gradual commitment, leading the other party to accept add-ons little by little rather than comparing different offers from the start.

For example, in commercial sales, the tiered offer would directly present three versions of a product (standard, intermediate, premium), whereas the staircase offer would begin with a basic version, then progressively add an additional warranty, an after-sales service, or accessories to encourage the customer to pay more.

The tiered offer works well when the other party needs to compare and make a decision based on their needs, whereas the staircase offer is more effective when you want to shift the perception of value over the course of the discussion and encourage gradual acceptance of a more advantageous offer.

• Present several variants of equivalent value to the seller so that the buyer chooses rather than simply saying yes or no
• Surface the other party's hidden priorities and preferences by observing which option they lean towards
• Anchor the discussion on the 'how' and the scope rather than on price alone
• Preserve the relationship by giving the buyer a sense of control and freedom of choice
• Protect your margins by concealing concessions within predefined tiers (drawers)

Commercial · The IT provider's three packages: Faced with a client demanding a discount on a maintenance quote, a software vendor presents not a revised price but three 'tiered' offers of equivalent value to itself: an Essential package (fewer tickets and a wider response window, low price), a Standard package (the initial quote), and a Premium package (priority intervention and additional hours included, high price). Instead of haggling over the figure alone, the client settles on the Standard package while negotiating a payment deadline. The vendor thus discovers that the client's true priority was cash flow, not price, and closes the deal without eroding its service margin.

Everyday life · The garage owner's choice: A motorist is hesitating over a costly repair. The garage owner offers three tiers: a minimal safety repair, a full repair with original parts, or an all-inclusive package with a service and extended warranty. By reasoning in terms of options rather than a single 'take it or leave it' quote, the customer feels in control of the decision and settles on the intermediate option, revealing that the constraint was the monthly budget rather than the total amount.

• Offering tiers that are NOT of equivalent value to you, so that the customer consistently chooses the option that is least profitable for you
• Multiplying the options (five or six tiers) and triggering choice paralysis rather than a decision
• Revealing your preferred option from the start, which destroys the technique's function of revealing the other party's preferences
• Using the tiers as mere window-dressing for a discount, turning the technique into haggling over price
• Failing to work out in advance the real value of each tier and improvising, at the risk of conceding more than intended

The difficulty of this technique is written into its very description: it creates the illusion of choice. Yet choice is precisely what underpins consent, and a technique that stages it strikes at the heart of a negotiation's good faith. The line is nonetheless one that can be drawn with precision. Presenting several genuinely open options, ones you would sincerely be prepared to honour if the other party selected them, is a service rendered: the other party compares, weighs things according to their own priorities, and decides better than when faced with a single offer. The practice becomes improper the moment an option is there only so as not to be taken, placed there to make its neighbour shine, what the literature calls the decoy effect. Consent then rests on a stage set. The test is clear and you can apply it to yourself before the meeting: if the other party chose the tier you are not expecting, would you be put out? Any discomfort at that question is the mark of staging. Offering genuinely open options respects choice; arranging options destined never to be taken is a staging of choice.
