Fake‑Door to First‑Dollar: 5 Payment‑Light Experiments You Can Run in 72 Hours

What it is: a pricing page with a clear outcome and a buy CTA wired to an off-the-shelf payment link (Stripe/PayPal payment link or PSP-hosted checkout) so purchases require no backend build. Use it to validate willingness to pay for a specific outcome: an early-bird seat, a lifetime microfeature, or access to a closed alpha.

Telemetry map: intent = CTA clicks; commitment = customer begins payment flow (payment link open); conversion = successful payment & receipt. Record referrer, cohort, and variant (price or copy). Decision rule: ship the feature if conversion ≥ your threshold (e.g., 2–5% from targeted landing traffic) and initial ARPU covers incremental build cost within 6–12 months.

What it is: collect a tokenized card via your PSP client SDK and optionally run an auth-only hold. That hold is an inexpensive, highly credible signal — it requires a real card and the user’s willingness to commit funds without capturing them. Use for reservation mechanics, limited presales, or high-consideration features.

Telemetry map: intent = open of payment modal; commitment = tokenization success & auth hold created; conversion outcome = capture or explicit opt-in to convert token into a charge. Decision rule: if >N users create tokens and >M% respond to follow-up to convert, invest in the backend flow that will capture tokens and deliver product.

What it is: charge a small refundable deposit ($5–$50) to reserve a seat, feature spot, or early access. It reduces friction compared to full-price purchases while raising the psychological and transactional cost above a click or email capture.

Telemetry map: intent = deposit page views & clicks; commitment = successful deposit payment; conversion = deposit holders converting to full price or retained as refundable holders who respond to your outreach. Decision rule: if deposit-to-convert rate exceeds your minimum (e.g., 20–40% depending on cohort), you have a viable pricing anchor.

What it is: provide a short, high-value interaction (advanced demo step, export, or a 24–72 hour access pass) behind a small payment. The offer is: pay to see the feature now. This is effective when the value can be demonstrated in minutes and the product’s ‘aha’ moment is gated.

Telemetry map: intent = view of gated CTA; commitment = payment for timed access; conversion = subsequent full purchase within retention window. Decision rule: run the gated access test for a fixed cohort and escalate to subscription/pilot if paid-access users convert at a materially higher rate than control.

What it is: run several compact payment surfaces in parallel: pure fake-door (Reserve button + manual follow-up), immediate payment link, refundable deposit, tokenization+auth, and timed-access. The goal is to find the minimum friction that still produces an on-chain or PSP traceable commitment.

Telemetry map: use three universal metrics across all variants: intent (CTA click), commitment depth (email + payment modal or token creation), and conversion outcome (successful payment or captured charge). Predefine escalation criteria: e.g., choose the winner if conversion rate and ARPU reach thresholds and you can project ROI on full build costs.
