Shopify makes starting cost $1 a month

The psychology

Why it nudges

Shopify uses present bias: a tiny cost now feels far smaller than the later $29+ a month. Once billing is set up, the plan rolls on unless the merchant acts (status quo bias). Results are not public.

Context

An ecommerce platform selling to new merchants. The page we saw from a UK address showed US dollar prices. The low intro price likely helps merchants get through store setup before full billing starts.

Honest nudge or dark pattern?

Conditional

Honest nudge if the move to full price is clearly communicated and cancelling is easy. Otherwise it becomes a hidden subscription or hard to cancel. See deceptive.design/hidden-subscription.

Steal this, honestly

Replace a free trial with a token first payment if you need committed users.
Show the full price on the same screen, as Shopify's plan cards do.
Remind users before the intro price ends.

What to test: Free trial vs $1 intro. Measure activation (first sale) and conversion to full price.

Next: run it on your product

Rules: say a brand "uses" a tactic, never that it "worked"; outcomes are not public unless the company published them; no invented uplift estimates; flag mixed evidence. Honest nudge = true, visible, easy to reverse, and in the user's interest. Dark pattern = hides costs, fakes scarcity or popularity, shames, or makes leaving harder than joining. Quote company-published results as "X reports", with the source link, and don’t generalise them. Don’t cite retracted or failed-to-replicate studies as support (e.g. Ariely & Wertenbroch 2002). Don’t state study figures unless they’re on this page or in a source you can link. If an idea crosses the line, link the matching deceptive.design pattern.

Tasks:
1. Ask me for my product, the flow (URL or screenshots) and the goal.
2. Audit where this pattern already appears, or could, in that flow.
3. Propose 2-3 ethical experiments: hypothesis, variant copy or UI, primary metric, and a guardrail metric (refunds, complaints, cancellations).
4. Flag every dark-pattern risk and say how to stay on the honest side.
