Usage and invoices

The Billing page shows what you have spent and why. What you see depends on your role:

Tab	Who sees it	Scope
Overview	Everyone	Your own credits. Admins and billing admins also see the plan summary and recent organization activity.
Plan	Admin, Billing Admin	The organization’s subscription.
Seats	Admin, Billing Admin	The organization’s seat pool.
Usage	Everyone	Your own balance and your own labs.
History	Admin, Billing Admin	Every credit movement in the organization.

Credit figures always describe your own balance, even for an admin: each member spends their own credits, and the organization holds none of its own.

Overview tab

The Credits this period card shows a meter of credits used out of your grant, the credits remaining, and when they renew:

Line	Meaning
Refreshes followed by a date	Seat credits renew on that date.
Refreshes monthly	Seat credits renew every month.
One-time grant, does not renew	Your organization is on Community, whose credits are granted once.
Concurrent sessions · up to N	How many labs can run at once across your organization, when a limit is set.

Admins and billing admins also see the plan summary (plan, Billing cadence, Seats, Credit grant, and Renews or Cancels date) and a Recent activity list of the latest credit movements.

Usage tab

This period

Granted, Used and Remaining show where your own balance stands right now. Granted is what you had this period, spent or not, so a zero means you had no credits.

What a lab costs

A reference table of each Environment and its Credits / hour. See How a lab consumes credits.

Your labs

Every lab charged to you, so you can check a charge against a lab you remember running. A lab appears here when it ends.

Column	Meaning
Session	The lab session.
Started / Ended	When the lab started and ended.
Billed for	The running time you were charged for. When the lab was paused, it reads, for example, 1h 10m less 20m paused: paused time is free.
Rate	The environment’s credits per hour, for example 2/h.
Credits	What the lab cost, to the hundredth of a credit.

If you have not run a lab yet, the table reads No labs charged yet.

History tab

The Credit ledger lists every credit movement in the organization, most recent first. Because each member has their own balance, the Member column says whose balance moved, and Balance is that member’s balance after the movement.

Column	Meaning
Type	The kind of movement (see below).
Member	Whose balance changed.
Reference	What the movement relates to, such as a lab session.
Date	When it happened.
Amount	Credits added (positive) or spent (negative).
Balance	The member’s balance afterwards.

Movement types

Type	Meaning
Session usage	A lab ended and its cost was charged.
Plan credit grant	A plan granted credits: the one-time Community welcome credits, or a paid seat’s monthly renewal.
Grant expired	Unused credits were cleared just before a monthly renewal. Seat credits do not roll over.
Cohort overage	Cohort places beyond those included, paid in credits before launch.
Credit transfer	Credits given from one member to another. A transfer shows as two rows: one for the giver, one for the recipient.
Seat assigned	A paid seat was assigned to the member, with the credits left on it.
Seat released	A paid seat was taken back, with the credits left on it.
`VOUCHER_REDEMPTION`	A member redeemed a credit voucher.

Invoices and payment

Klastro charges your subscription through Stripe. There are no separate invoices for lab usage: labs are paid in credits, and once your credits run out, labs pause rather than run up an overage.

Invoices and receipts are sent by email to the Billing email set in your organization settings. See Organization settings.

To update your payment method, change plan or cancel:

Open Billing, then the Plan tab.
Click Manage subscription.
Make your changes in the secure billing portal.

If the portal does not open, the page shows Could not open the billing portal. Try again, and if it keeps failing, open a support ticket.
