## FAQ

**How much does Observe cost?**
Free tier is free forever. Pro is $29/mo, Team is $99/mo, billed monthly. No per-seat charges.

**How much does the Platform cost?**
Platform pricing is custom. Contact us for details.

**Do I need a credit card to start?**
No. Sign up for Observe Free with no credit card.

**Can I cancel at any time?**
Yes. No contracts, no cancellation fees.

**We already use Stripe. Why would we need Tanso?**
Stripe handles payment collection. Tanso handles everything upstream: which customers get access to which features, how much they've consumed, whether they're within limits, what it cost you to deliver, and what your margin looks like. Tanso syncs invoices to Stripe automatically.

**Can I change my customers' pricing without a code deploy?**
Yes. Plans, pricing rules, usage limits, and credit grants are all configured in the Tanso dashboard. Changes take effect immediately with no code changes or deployments.

**What is a pre-flight entitlement check?**
Before your app runs expensive compute (LLM inference, API calls, data processing), call Tanso's entitlement API. Tanso checks the customer's plan limits, credit balance, and subscription status. If they don't have capacity, the request is denied before you incur infrastructure costs.

**How long does integration take?**
Most teams are billing in a day. One API call for entitlement checks, one for usage events.
