Pricing

One price for the whole org.
Set by how many of you there are.

Not per person, not per term. Drag the dial — that's the whole pricing model.

Hitting the limit

Only growth stops.

Go past your plan and you can't add the next person. Nothing else changes.

What stops

  • Approving requests past capacity (people can still send them).
  • Un-archiving someone.

What doesn't

  • Every member keeps access.
  • Every page keeps working.
  • Exports keep working.
When things change

A failed card or a cancellation deletes nothing.

Payment failedPast due

The card didn't go through

  1. Stripe retries and emails the billing address.
  2. New members wait until it's sorted.
  3. Updating the card settles it at once.

You want to stop paying

  1. A few clicks in the billing portal; you keep the month you paid for, then drop to Free.
  2. 40 people stay 40 — you just can't add the 41st.
  3. Changed your mind? Resume before it ends.

Questions

Asked before paying.

Is this the same as the dues we track?

No. This is what your org pays us. The dues and ledger you keep in the app never touch it.

Who handles billing?

Your org admins. They add the card, change the plan and see the invoices.

We're bigger than 120.

Billing asks for a quote instead of a card, and nothing stops working meanwhile.

We run more than one org.

Admins of two or more orgs can ask about a group plan from Billing.
