Billing Sandbox

Spaces on their own Stripe test clock, for QA of usage billing. Create a space, add usage, and move its clock forward to settle a period, or follow a guided scenario.

Guided QA

One billing cycle end to end: usage, prepay, settlement and a spend limit.

1. Create a Starter space, billed monthly

Starter includes 50 consumers and 100 GB of storage.

Usage at zero
A paid first invoice
Usage billing on this period

2. Check the billing page

Log in as the space's owner to see it.

The empty state: no usage, no overage, no settled periods

3. Add 550 consumers and 150 GB of storage

A projected overage of $85.00: $75.00 for 500 consumers, $10.00 for 50 GB
Alerts 50, 75, 90 and 100 on both rows

4. Prepay 200 consumers

Consumers show 200 under Next while Prepay stays 0: prepay starts next period
The upcoming invoice gains a $27.00 prepay line

5. Check the billing page again

Usage over the allowance, the projected overage and the staged prepay

6. Advance the clock to settle the period

Moves past the period end plus the 2 day settlement delay. Takes a minute or two.

Settled 1 usage period(s), and an invoiced settled period of $85.00
A paid renewal invoice (subscription_cycle) of $232.00: the plan, the prepay and the $75.00 and $10.00 overage lines
Consumers at prepay 200, with usage back to 0

7. Set a $50 spend limit

8. Add 800 consumers

550 over the allowance of 250, so about $83 spent against the $50 limit
Blocked until the period ends, and would charge $50.00

9. Try editing in the app

A spend limit banner in the space
Uploading an asset or creating a kit fails; viewing and deleting still work

10. Remove the limit

The block lifts right away

Each scenario starts with a new space. After advancing, the clock runs ahead of real time: plan changes made in the app can be rejected, and a spend limit block won't expire on its own. Stripe deletes test clocks after 30 days, so old spaces stop working.
