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

​
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.

​
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∗∗beyonditsincluded10,andTeamis∗∗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

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.

​
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

​
Cancelling

Cancellation takes effect at the end of the current billing period. Your organization moves to the Free plan — data retention drops to 14 days and any data older than that becomes inaccessible.
  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 10K/month
  • Data retention drops to 14 days
  • Max 2 projects and 1 member
