How Commet generates invoices, what they contain, and when customers are charged.

Invoices are the financial records Commet generates automatically whenever a subscription event or billing cycle occurs.

Invoice types

Type	When Generated	Example
Recurring	Every billing cycle	$99 plan base + $12.50 overage
Overage	Between cycles (quarterly/yearly only)	15k extra API calls billed monthly
Plan change	Customer upgrades mid-cycle	Starter to Pro, prorated $45
Credit purchase	Customer buys a credit pack	500 credits for $40
Balance top-up	Customer adds funds	$50 balance top-up
Adjustment	Manual correction issued	$10 refund for service issue

When charges happen

Component	When Charged	Example
Plan base price	Advance (period start)	$99 on Jan 1
Boolean features	Included in plan base	SSO, Custom Branding
Metered overage	True-up (period end)	2,500 extra API calls
Included seats	Advance (with base)	5 editor seats
Additional seats	True-up (period end)	3 extra seats added mid-cycle

Billing intervals

Interval	Base Invoice	Overage Invoice	Consumption Reset	Example
Weekly	Every 7 days	Included in recurring invoice	Every 7 days	$25/week every Monday
Monthly	Every month	Included in recurring invoice	Every month	$99/month on the 1st
Quarterly	Every 3 months	Monthly	Every month	$297 base quarterly, overage monthly
Yearly	Every 12 months	Monthly	Every month	$899 base yearly, overage monthly
One-time	Single charge at checkout	At period end (if overage exists)	Never	$299 lifetime, no recurring charges

For quarterly and yearly plans, overage is calculated and invoiced monthly even though the base charge is less frequent. For weekly plans, everything runs on a 7-day cycle. For one-time plans, the customer pays once at checkout and never receives a recurring invoice — only overage charges if applicable. See One-Time Payments for details.
