## Understanding Prorated Billing

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

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

### How It Works

Prorated billing applies when you add seats during a billing period: a 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 your seat count decreases from the next billing period onward. Removed seats are not credited mid-period. Prorated additions can make invoices harder to read. The following section walks through an example of how the correction appears on your 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>
  API and Workflow usage can appear as separate line items based on usage. See [Pricing](/en/admin/billing/pricing#api) and [Workflow cost management](/en/using-langdock/workflows/guides/cost-management) 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: **€15.00**
* API usage: **€25.00**
* Workflow AI Model Usage: **€75.00**
* Total usage costs: **€115.00**

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