Charge $29 a month.

Make Leaseline Pro a $29 monthly subscription.

Bill customers every month and let them cancel on their own.

# 1. Offer.create
OFFER=$(curl -X POST https://api.sb/leaseline.app/offers \
  -H "Authorization: Bearer $STARTUP_BUILDER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"price":{"amount":29,"currency":"USD"},"interval":"month","terms":"Monthly, billed in advance. Cancel any time from the billing portal."}' | jq -r '.offer["$id"] | split("/") | last')

# 2. Offer.publish
curl -X POST https://api.sb/leaseline.app/offers/$OFFER/publish \
  -H "Authorization: Bearer $STARTUP_BUILDER_API_KEY"

import { $ } from 'startup-builder'

const offer = await $.Offer.create({ price: { amount: 29, currency: 'USD' }, interval: 'month', terms: 'Monthly, billed in advance. Cancel any time from the billing portal.' })
await $.Offer.publish({ offer: offer.$id })

OFFER=$(npx startup-builder do Offer.create --json '{"price":{"amount":29,"currency":"USD"},"interval":"month","terms":"Monthly, billed in advance. Cancel any time from the billing portal."}' | jq -r '.offer["$id"] | split("/") | last')
npx startup-builder do Offer.publish --json '{"offer":"'"$OFFER"'"}'

  "name": "do",
  "arguments": {
    "code": "const offer = await $.Offer.create({ price: { amount: 29, currency: 'USD' }, interval: 'month', terms: 'Monthly, billed in advance. Cancel any time from the billing portal.' })\nreturn await $.Offer.publish({ offer: offer.$id })"
  }
}

Change it

  • Add a $290 annual plan.
  • Give a 14-day free trial.
  • Raise the price for new customers only.

Under the hood

Systems
Billing, Ledger, Tax
Nouns
Offer, Price, Subscription, Invoice, Entry
Events
Offer.created, Offer.published, Offer.subscribed, Subscription.renewed
Stripe objects
Product, Price, Checkout Session, Subscription, Invoice, Customer Portal, Tax Calculation

Each Customer then subscribes at checkout, which runs Offer.subscribe. Revenue posts as deferred and moves to earned as each month passes. A failed renewal retries on the dunning schedule, then pauses the Customer's Entitlements.
