This skill is the delta versus `pricing`, `discounts`, and `post-purchase`. One-off digital products → `digital-product-pricing`.\n\n## When to use\n\n- Designing or reviewing plan tiers and their prices\n- Choosing flat-rate vs pay-per-use, or pricing seats, storage, minutes\n- Adding a paid membership perk, or rewards for members\n\n## When not to use\n\n- One-off digital products → `digital-product-pricing`\n- Shared digit and component rules in isolation → `pricing`\n- Wording a plan discount → `discounts`; measuring willingness to pay per month → `price-research`\n\n## Inputs\n\nCollect, or state your assumption: tiers, prices, billing period; any per-unit component; whether members optimize for quality or lowest price; which tier you want people to move to; order/usage frequency.\n\n## Procedure\n\nOnly the rules that change for recurring plans. Shared catalogs live in the Depth skills.\n\n1. **Lead with a flat rate that covers what most members want**, priced *above* the pay-per-use equivalent. Keep pay-per-use only as a low-commitment entry. The source study is purchasing professionals buying usage-based services; applying it to consumer memberships is a transfer. Depth: `pricing`.\n2. **Put the upgrade path on the same left digit.** No just-below on the lower tier if you want Basic → Pro ($40 → $48, not $39.99 → $48). Depth: `pricing`.\n3. **Simplify every component.** Rounded per-seat / per-GB prices, the same ending, no admin fee. Depth: `pricing`.\n4. **Paid perk needs a minimum.** A membership that unlocks free shipping or member rates raises spend; without a minimum, members split into many small orders. Depth: `post-purchase`.\n5. **Rewards: automatic, single tier, threshold.** Optionally variable; combining variable rewards with auto-enrollment is untested. Depth: `post-purchase`.\n\nShared, unchanged: quality-led → rounded, price-led or post-trial → just-below (subject to step 2); \"for $0\" on free trials; abandoned-signup reminder at 24–72 h is an assumption transferred from carts. Depth: `pricing`, `promotions`, `post-purchase`.\n\n## Worked example\n\nMembership site, plan: Basic $9.99, Pro $29.99, pay-per-video $2.49, extra seats $4.61 + $6 admin fee, opt-in 3-tier rewards, goal: more Basic→Pro upgrades.\n\n- **$10 → $30** removes the just-below start that discourages the step up. Same-left-digit ($40.50 → $48.50) is the stronger version and needs closer tiers.\n- Pay-per-video stays as entry, priced so ~10 videos equals Pro.\n- Seats: **$5, no admin fee**.\n- Rewards: **auto-enroll, one tier**.\n\n## Output\n\n| Item | Value |\n|---|---|\n| Tiers | Basic $10/month · Pro $30/month |\n| Upgrade path | No .99 on Basic |\n| Pay-per-use | Entry only; heavy users cheaper on Pro |\n| Components | $5 per extra seat, no admin fee |\n| Perk / rewards | Minimum order on the perk; auto-enrolled single tier |\n| Why | one line per choice |\n\n## Common mistakes\n\n- Adding a mid-tier to \"shrink the jump\" — the jump is the .99 boundary; fix the digits first.\n- Pricing the flat rate at the pay-per-use equivalent \"to be fair\" — people pay more for the cap.\n- A perk with no minimum — members fragment usage to exploit it.\n- Opt-in tiered rewards — automatic, single tier, threshold reward.\n\n## Quick reference\n\n| Situation | Do | Depth |\n|---|---|---|\n| Plan structure | Flat rate above pay-per-use; pay-per-use as entry | `pricing` |\n| Want upgrades | Same left digit; no .99 on the lower tier | `pricing` |\n| Seats / storage | Rounded, same endings, no fee | `pricing` |\n| Membership perk | Minimum order/usage | `post-purchase` |\n| Member rewards | Auto-enroll, single tier | `post-purchase` |\n\nEvidence and effect sizes: see [reference.md](reference.md).\n"
