Billing is visible to Owner, Admin, and Billing roles. Only Owner and Billing can make changes — upgrade, downgrade, cancel, or update payment details. Admin can view the plan and usage but cannot modify billing. Editor and Viewer have no billing access at all. See Organizations for the full role breakdown.
Zespan bills per organization through Polar. Manage your subscription from Settings → Billing.

Plans

​
Your 14-day trial

Every new organization starts on a 14-day Team trial — no credit card required, and nothing is charged automatically when it ends.
Your trial includes everything on the Team plan: Team’s features, and Team’s limits on seats, trace quota, data retention, projects, and ZespanPilot usage. See the plan comparison above for the exact numbers.
1

The trial starts automatically

A new organization’s 14-day trial begins the moment it’s created — there’s nothing to activate.
2

You're reminded as it winds down

Zespan emails your organization’s owners 7 days, 2 days, and 1 day before the trial ends, plus a final email on the day it ends.
3

Pick a plan before it ends

From Settings → Billing, choose Solo, Pro, Team, or Scale — or do nothing and your organization moves to Free.

​
When the trial ends

Projects, members, and existing data are always kept, no matter which plan you land on.
  • You chose a paid plan. Your organization continues on it. Team or Scale keeps everything the trial included. Solo or Pro doesn’t include every Team feature, so anything that requires Team (see What’s gated by plan below) becomes unavailable until you upgrade again.
  • You didn’t choose a plan. Your organization moves to Free: ingestion pauses once you hit the Free plan’s trace limit, and Guardrails, Policies, and Evaluations become unavailable.
You can change plans at any time from Settings → Billing — see Upgrading your plan below.
Trials are for organizations created going forward. An organization that existed before this feature shipped keeps its current plan and does not receive a trial.

​
Overage billing

When your organization exceeds its monthly trace quota, additional traces are billed at the end of the period: On the Free plan there is no overage — traces are dropped once the monthly limit is reached. The usage bar in Settings → Billing shows your current month-to-date count against your quota and updates in real time. A sample trace sent during onboarding counts as 3 events.

​
Extra seats

Each plan includes a set number of members before you pay per seat: Free and Solo don’t allow extra seats at all (you must upgrade to add members), Pro is $10/seat/month** beyond its included 10, and Team is **$8/seat/month beyond its included 15. Settings → Billing shows a seat-cost preview before you confirm an invite that would push you over your included count.

​
What’s gated by plan

Semantic Judge guardrail usage on Zespan’s AI is counted per Semantic Judge rule evaluated, not per check. A check that runs several Semantic Judge rules counts once for each. See Guardrails → AI usage limits.
Beyond trace quota, retention, and seats, several features require a specific plan or higher:
This table lists plan-level feature gates as implemented in the product. If a page elsewhere in these docs states a different minimum plan for a specific feature, trust that page’s own gating note first — some features (like Audit log) are gated by plan rather than by role, so every role can see them once the organization is on a qualifying plan.

​
What a locked page shows

When a whole page needs a higher plan than yours (for example Evaluations, Datasets, Alerts, Simulations, Cost attribution, Forecasts, Guardrails, Policies, Users, Incidents or Annotations), the page does not just stop at a wall. It shows:
  • The page’s title, what it is for, and when to come here.
  • What you get on the plan that unlocks it, with its plan chip and price.
  • Upgrade to , the one main action, and Compare plans, which opens this page. Only Owners and Billing-role members can change the plan, so for Admins, Editors and Viewers Compare plans is the main action and a note says to ask an Owner or a Billing member to upgrade.
  • A grey outline of how the page is laid out, captioned Example layout. Your data appears here after you upgrade.
The outline is bars and boxes only. It never shows sample numbers, names or charts, and it never opens the demo project, because nothing on a locked page is real data. A smaller feature inside a page that you can use (for example one panel) keeps a short upgrade notice instead. A page is shown as locked only when Zespan knows your organization’s plan is below the one the page needs. Every role, including Viewers and Editors, sees the pages its organization’s plan includes.

​
Opening billing settings

  1. Sign in as an Owner, Admin, or Billing-role member of your organization.
  2. Click your organization name in the top navigation.
  3. Go to Settings → Billing.
You’ll see your current plan and month-to-date usage. Owner and Billing additionally see options to upgrade, downgrade, or manage payment — Admin sees this page read-only.

​
Upgrading your plan

  1. In Settings → Billing, click Upgrade or Change plan.
  2. Select the plan you want.
  3. If you don’t have an active subscription yet, you’re redirected to a Polar checkout page — enter or confirm your payment details. Zespan never stores card information. If you already have an active subscription, the change applies in place (no redirect) and is prorated automatically.
  4. Once payment is confirmed, your new limits take effect immediately, and Zespan emails the organization’s owners a confirmation.
Mid-month upgrades are prorated for the remaining days in the billing period.

​
Downgrading your plan

  1. In Settings → Billing, click Change plan.
  2. Select a lower plan (Solo, Pro, or Team — downgrading to Free is done by cancelling instead).
  3. Zespan applies the change to your existing subscription via Polar with prorated billing — no separate checkout is needed.
  4. The new (lower) limits take effect immediately, the same as an upgrade.

​
Payment, invoices, and billing details

  1. In Settings → Billing, click Manage billing.
  2. You’re taken to the Polar customer portal where you can:
    • Update your credit card or payment method
    • Download past invoices as PDFs
    • Update billing address or tax ID

​
Subscription status

The plan card on the billing page shows one status for your subscription:

​
Cancelling

Cancellation takes effect at the end of the current billing period. Your organization moves to the Free plan and data retention drops to 14 days. Data your previous plan covered is kept for 30 days after the change; after that, data older than 14 days is permanently deleted. See Data retention and deletion.
  1. In Settings → Billing, click Manage billing.
  2. In the Polar customer portal, cancel your subscription.
  3. Your current plan stays active until the end of the billing period.
After downgrade to Free:
  • Traces capped at 50K/month
  • Data retention drops to 14 days
  • Max 2 projects and 1 member
