# How invoices are generated
> ClassQuill automatically creates invoices when sessions are completed. Here's how the billing cycle works.
## Automatic invoice generation
When a session is marked as **completed**, ClassQuill automatically generates an invoice and sends it to the parent (or directly to the student if no parent is linked). No manual action required from tutors or admins.
The invoice includes:
* Session date, time, and duration
* Tutor name
* Rate per hour and total amount
* Payment due date (set by your org)
* Payment options (bank transfer, or card if Stripe is connected)
***
## Manually generating an invoice
Org admins can also generate invoices outside the automatic cycle — for example, for a bulk session package or a custom charge.
1. Go to **Payments → Invoices** in the org sidebar.
2. Click **New invoice**.
3. Select the student and enter the line items.
4. Set a due date and click **Send**.

## Invoice statuses
| Status | Meaning |
| ----------- | ------------------------------------------------------ |
| **Pending** | Sent, awaiting payment |
| **Paid** | Payment confirmed (card or manually marked) |
| **Overdue** | Past due date, payment not received |
| **Voided** | Cancelled (e.g. session was cancelled after invoicing) |
***
## Marking an invoice as paid manually
If a parent pays by bank transfer or cash:
1. Go to **Payments → Invoices**.
2. Find the invoice and click it.
3. Select **Mark as paid** and enter the payment method and date.
Card payments processed via Stripe are marked as paid automatically.
