# How to add a Custom Line Item to a Generated Booking

## Add a custom line item to a generated booking to invoice a client for non-standard services or bundled packages that you offer.

**Note:** This feature is **only** available to *Platinum Members*. To add custom line item(s) to your generated project/session bookings, signup for the **[Platinum Membership Plan](https://engineears.com/add-subscription)**.

Service Providers can bill clients for additional non-standard services being offered when generating a booking link for a standard service (mixing, mastering, dolby atmos, recording session). This enables greater flexibility in the services offered on the EngineEars platform, consolidated payment collection and payouts for services rendered, and the ability to bundle multiple services or customize differentiated offerings as an add-on.

This article covers the following:

- **[Add a Custom Line Item to a Generated Session Booking](https://support.engineears.com/en/knowledge-base/how-to-add-a-custom-line-item#custom-line-item-session-bookings)**

 

### Add a Custom Line Item to a Generated Project Booking

**Notes:**

- You **cannot** edit or delete a custom line item for a generated project booking link once the client has submitted payment for the project booking. If new charges arise, you should create a new generated project booking link.
- To itemize separate charges, you can add **each** individual custom line item one at a time to your generated project booking to display the items and their prices separately in the order summary. Alternatively, you can bill all the added charges as a lump sum under a single custom line item by entering the **total service rate** for the sum of all added charges in the service rate field. In the customer description field, specify the individual items and their individual prices to reflect the itemized details being charged in total.
- Payouts occur when the service on the project booking link has been completed in full, custom line items are also paid out at the same time. If the booking link is for full-stems mixing, once the mixing project has been approved and completed by the client, then the payouts for the mix plus any custom line items billed on the booking will be **paid out together** (regardless of timing of deliverables specified for the custom line item).
