## Understanding Prorated Billing

Invoices adjust when your team size changes during a billing period, but additions and removals are handled differently.

### Example Invoice

| **Description** | **Qty** | **Unit price** | **Tax** | **Amount** |
| - | - | - | - | - |
| Workflow AI Model Usage<br />9 May 2026 to 9 Jun 2026 | 75,000 | €0.001 | 0% | €75.00 |
| Remaining time on 3 × Langdock Business (AI models included) after 24 Apr 2026<br />24 Apr to 9 May 2026 | 3 | | 0% | €43.50 |
| Unused time on 2 × Langdock Business (AI models included) after 24 Apr 2026<br />24 Apr to 9 May 2026 | 2 | | 0% | -€29.00 |
| Langdock Business (AI models included)<br />9 May 2026 to 9 Jun 2026 | 3 | €29.00 | 0% | €87.00 |
| Langdock Business Max<br />9 May 2026 to 9 Jun 2026 | 1 | €119.00 | 0% | €119.00 |
| Extra Usage in Chat & Agents<br />9 May 2026 to 9 Jun 2026 | | | 0% | €15.00 |
| API<br />9 May 2026 to 9 Jun 2026 | | | 0% | €25.00 |
| | | **Subtotal** | | €335.50 |
| | | **Total** | | €335.50 |
| | | **Amount due** | | **€335.50** |

Personal API key usage is included in the **Extra Usage in Chat & Agents** amount. The **API** amount covers workspace API key usage.

<Note>
  Taxes depend on your billing setup and region. Your invoice may include VAT or other taxes.
</Note>

### How It Works

When you add a member during a billing period, a freed seat is reused first at no additional charge for the current period. If the member increases your total seat count, the new seat is charged only for the days remaining in the current period. Removing a seat works differently. The seat stays billed through the end of the current period and remains reusable. The renewal quantity reflects active users from the next billing period onward. Removed seats are not credited in the current period. Prorated additions can make invoices harder to read. The following section walks through an example of how the correction appears on your invoice.

Seat changes take effect immediately. The related billing changes are updated daily. Prorated charges and credits appear on your next invoice. For some annual subscriptions, added seats, seat tier upgrades, and usage charges are billed monthly before renewal. This can include Workspace API usage, Extra Usage, and Workflow AI model usage. If your workspace uses [usage credits](/en/admin/manage-usage/usage-credits), Extra Usage, API usage, and Workflow AI model usage are paid from the credits, so they do not appear on your monthly invoice.

You can split the seat subscription part of the invoice into two sections:

**Past period corrections:** prorated charges for users added during the previous period. Seat removals are not credited here; they reduce your seat count from the next period.

**Upcoming period charges:** the current number of users at the start of the new period.

<Note>
  Workspace API usage and Workflow AI model usage can appear as separate line items based on usage. The [Workflows plan](/en/admin/billing/subscription) is a subscription charge, while [Workflow AI model usage](/en/using-langdock/workflows/guides/cost-management) is a metered charge. See [Pricing](/en/admin/billing/pricing#api) and [Workflows pricing](/en/admin/billing/pricing#workflows) for details.
</Note>

### Breakdown of the Example

This invoice combines a prorated seat change, seat subscription costs, and usage costs.

**Seat corrections for the previous period:**

* 1 Business seat was added on April 24th, bringing the total to 3 Business seats.
* Langdock charges the remaining half month for 3 Business seats: €43.50.
* Langdock credits the unused half month for the 2 original Business seats: -€29.00.
* Net seat adjustment: **€14.50**

**Seat charges for the upcoming period:**

* 3 Business seats × €29 = **€87.00**
* 1 Business Max seat × €119 = **€119.00**
* Total seat subscription costs: **€206.00**

**Usage charges for the previous period:**

* Extra Usage in Chat & Agents, including personal API key usage: **€15.00**
* Workspace API usage: **€25.00**
* Workflow AI Model Usage: **€75.00**
* Total usage costs: **€115.00**

**Total:** €14.50 + €206.00 + €115.00 = **€335.50**
