Quota
How quota-based billing works for your customers
Plans can include a quota of a durable resource at no extra cost — tasks, WhatsApp numbers, parallel automations. When your customer goes over the included amount, they're charged per extra unit. Unlike a usage meter that only counts up, a quota balance rises and falls as customers create and delete.
How it works
Plan Pro: 15 included tasks, $0.75/extra task
Your customer has 25 tasks
Included: 15 tasks (no charge)
Extra: 10 tasks × $0.75 = $7.50/moThis assumes the extra tasks stay for the whole period.
Quota rises and falls
Because customers create and delete, the balance moves during the period. Commet bills the extra units above the included amount, prorated for how long they're held — so a brief spike costs less than holding units all month.
Your customer starts the month at 15 tasks, then creates 10 more on day 15 (25 total).
Included: 15 tasks (no charge)
Extra: 10 tasks held for 15 of 30 days
10 × $0.75 × (15/30) = $3.75What happens when you change the included amount
Adding more included units
More included units benefits your customers, so it applies right away.
You increase Plan Pro from 15 to 30 included tasks.
Your customer has 25 tasks (was paying for 10 extra at $7.50/mo).
After the change:
→ All 25 tasks are now within the 30 included
→ Extra charges drop to $0
→ Your customer sees the change immediatelyReducing included units
Fewer included units harms your customers, so it applies at renewal.
You decrease Plan Pro from 30 to 15 included tasks.
Your customer has 25 tasks (all included, $0 extra).
This period: Still 25 within the included amount, $0 extra
At renewal: 15 included + 10 extra = $7.50/moWhat happens when you change the price
Same as all price changes: your customers keep the current price until renewal. The new price applies starting next period.
| What your customer pays | |
|---|---|
| This period | Old price per unit |
| Next period | New price per unit |
Quota and upgrades
When your customer upgrades to a plan with more included units, their extra charges may decrease or disappear.
Example
Your customer is on Pro ($29/mo, 15 included tasks, $0.75/extra task).
They have 25 tasks — paying $36.50/mo total (15 included + 10 extra).
They upgrade to Scale ($79/mo, 50 included tasks, $0.50/extra task).
On day 15 of their cycle.
Credit:
Plan base: $29 × (15/30) = $14.50
Extra tasks: $7.50 × (15/30) = $3.75
Total credit: $18.25
Charge:
New plan: $79 × (15/30) = $39.50
Extra tasks: $0 — their 25 tasks are now within 50 included
Total charge: $39.50
They pay today: $21.25Your customer's 25 tasks are now covered by the Scale plan's 50 included tasks. They stop paying for extra tasks entirely.
