# How to record a customer self-billing invoice?

Use this function when your customer uses **self-billing** — meaning that the customer creates the invoice for your services on your behalf.

In Cloudex TMS, you should still create the **Outgoing invoice** as usual so that the revenue, customer debt and related Client orders are correctly recorded in the system.

Additionally, Cloudex TMS allows you to save the invoice number assigned by the customer in the **Self-billing No** field.

This is especially useful when the customer later makes a payment using their self-billing invoice number as the payment reference.

#### 1. How to enable self-billing for a customer?

You only need to configure this once for each customer that uses self-billing.

Go to: **Partners → Open the customer → Invoices**

1. Open the **Invoice** tab.
2. Select **Customer uses self-billing**.
3. Click the **Save** button.

After this setting is enabled, the **Self-billing No** field will become available on outgoing invoices created for this customer.

#### 2. How to enter the customer's self-billing invoice number?

Create the customer's **Outgoing invoice** in Cloudex TMS as usual.

On the outgoing invoice:

1. Find the **Self-billing No** field.
2. Enter the invoice number shown on the self-billing invoice received from the customer.
3. Click the **Save** button.

##### Example

Cloudex TMS outgoing invoice number: **INV-2026-01584**

Customer's self-billing invoice number: **SB-45879**

Enter **SB-45879** in the **Self-billing No** field.

The Cloudex TMS invoice number remains unchanged.

#### Why is the Self-billing No important?

Customers that use self-billing may use **their own invoice number** when making a payment.

Saving this number in Cloudex TMS makes it easier to identify which outgoing invoice the received payment belongs to and helps with automatic or manual payment matching.
