Pricing recommendations
- Set break-even at no less than $3.40 per user/month.
- For a 70% gross margin after Stripe fees, target about $12.18 per user/month.
- For pure usage-based billing, charge at least $7.38 per 1,000 API calls.
- Keep a base subscription fee so low-usage customers still cover support, auth, hosting, and billing overhead.
- Use Stripe metered billing only after you can reliably count billable events and explain usage on invoices.
