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

How It Works

Prorated billing means you only pay for the time a seat is active in your workspace. You can flexibly add or remove seats during a billing period and only pay for the time the seat is active, but this 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: adjust for users added or removed during the billing period.

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

API and Workflow usage can appear as separate line items based on usage. See Pricing and Workflow cost management for details.

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
