Is the free plan actually free, or a trial?
The single-lease calculator is free forever, with no account and no credit card — and it uses the exact same engine as Pro, so the numbers are identical. A free account adds a small saved portfolio (2 leases) and 25 API computations a month so you can integrate before paying.
What do I get for $39/month?
Pro is $39/month flat. It adds an unlimited lease portfolio, Excel/CSV/PDF exports of the amortization schedule, journal entries and disclosures, lease modifications and remeasurements, and 5,000 API computations a month at a higher rate limit — everything you need to actually close and support an audit, not just calculate.
Why isn't the free calculator enough?
The free calculator is genuinely accurate and unlimited — great for a quick answer or a sanity check. But a real close needs to save many leases, export audit-ready workpapers into your files, produce journal entries to post, and handle modifications. Those are the Pro features, so free pulls toward Pro exactly when your work gets real.
How is the API metered?
The API and MCP are usage-metered per computation. The free tier includes 25 computations a month; Pro includes 5,000. Classification calls are free (0 units). Going over is billed at a small per-computation rate rather than hard-blocked — talk to us about volume pricing for high-throughput agents.
Can AI agents use the paid features?
Yes. An agent authenticates with an API key tied to your plan, so a Pro key gets Pro limits. The MCP server and API expose the same compute, schedule, journal-entry and classification tools a human uses, with structured errors, idempotency keys and an inspectable request log.
Can I cancel anytime?
Yes — Pro is month-to-month with no contract. Cancelling stops the next cycle; you keep Pro through the period you've paid for and then revert to the free limits.
Your first schedule is free.
Try the calculator, then upgrade to Pro when you need to save, export and automate.
