Invoices and Billing Cycles
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 | Example |
|---|---|---|---|
| Monthly | Every month | Included in recurring invoice | $99/month on the 1st |
| Quarterly | Every 3 months | Monthly | $297 base quarterly, overage monthly |
| Yearly | Every 12 months | Monthly | $899 base yearly, overage monthly |
For quarterly and yearly plans, overage is calculated and invoiced monthly even though the base charge is less frequent.
