Endpoint first: full price and terms at step one

Show what the user is signing up for before the first step: the total price with mandatory fees, the renewal terms, the time involved and the data requested. The first price shown should be the final price. This removes the lowball gap and the refunds that come with it.

How it works

Saying no is easiest before the first step; every step after it adds commitment and new reasons to continue, so terms revealed late are accepted under pressure and regretted afterward. Showing the endpoint first moves the decision to the moment it can be made freely. It can lower early clicks somewhat, but buyers who go ahead know the price, which protects net revenue.

In the book. Refusing is easiest before anything has been agreed; each later step adds commitment, which is what the lowball exploits (Ch.3, pp.43, 53-57, 75-76). INF-T-CC-34 (Influence Ch.3, p.43)

In a product [S]. The first price display shows the final price, and the first step shows the endpoint. In 2025 a large home-rental marketplace moved to total prices by default worldwide (CASE-M04).

Evidence Evidence grade B. Moderate evidence: solid studies with some limits.. Field evidence shows late fees raise gross sales; all-in pricing gives up part of that gain for prices buyers can trust. Measure refunds and complaints to see the net.

Evidence warning

Expect gross checkout conversion to dip where fees used to appear late; judge the change on net revenue after refunds and chargebacks.

What the research says

The book observes that refusing is easiest before anything has been agreed, and its lowball examples work by revealing the real terms late.
Influence Ch.3, pp.43, 75-76
In a large ticket-marketplace experiment, all-in prices shown from the start led to fewer purchases and lower spending than fees added at checkout: the gross gain that late fees capture, and that this technique gives up.
Blake, Moshary, Sweeney & Tadelis, Marketing Science, 2021

How to build it

E-commerce: Include mandatory fees and a shipping estimate in the first price on product and listing pages, so the checkout total matches it.
Web: Above the first sign-up button, show a short "What you are signing up for": the price after any trial, the renewal date and how to cancel.
B2B: Put the full annual cost (seats, platform fee, onboarding) on the first quote, with optional items listed separately.
Mobile: On the subscription screen, state the price per period, the trial end date and the renewal terms above the subscribe button.

By product type

E-commerce / DTC: Purchase is the value event: all-in prices from the first product view are a lead lever from M1.

What can go wrong

"From $X" prices that few buyers actually pay.
Taxes or fees left ambiguous where they are mandatory.

TechniqueEvidence grade C. Limited evidence: few or small studies.
Reduce money: lower the cost and risk of the first try
cheaper, safer first step
When money is the scarce resource, let people try before paying, start with a small first purchase, show the full price early and make canceling easy. Remove the fear of paying for something that might not work.
TechniqueEvidence grade B. Moderate evidence: solid studies with some limits.
A commitment ladder that starts with a tiny yes
small first step, then bigger
Design a sequence where the first rung is something almost everyone accepts and each next rung asks a little more, with real value at every step: pick a topic, then set a weekly digest, then share it with the team.
TechniqueEvidence grade B. Moderate evidence: solid studies with some limits.
Foot-in-the-door ladder with the endpoint visible
small first step, larger steps later
Begin with a first step nearly everyone accepts (a free calculator, saving a result), then offer larger related steps: a profile, a first project, inviting a teammate, a trial, a plan. Each rung should deliver value on its own, stopping should cost nothing, and the endpoint (price, renewal, data) should be visible from the first rung.
TechniqueEvidence grade B. Moderate evidence: solid studies with some limits.
User-written goal, shown back
goal in the user's own words
Ask users to write, in one sentence, what they want to achieve, then show it back at useful moments: on low-motivation days, at the next milestone. Writing makes the commitment active and gives users a record of their own intent; when the goal is reached, prompt the next one.
TechniqueEvidence grade C. Limited evidence: few or small studies.
Opt-in public or chosen-audience commitment
share your goal with people you pick
Let users choose to share a goal with one to five people they pick, a coach or their team, with optional progress updates. Commitments seen by others are harder to drop; keep sharing optional, scoped and reversible, and never public by default.
TechniqueEvidence grade C. Limited evidence: few or small studies.
One add-on after the main choice, with a running total
single post-choice add-on
Offer at most one relevant add-on after the main item is chosen, unchecked, with its value stated and the order total updated in view. Sequence makes a small extra look minor; showing the total keeps the order from turning into a surprise that comes back as a refund.
