# Can I use the ServiceTitan API to create bills?

## Problem

The ServiceTitan API does not directly create bills. However, you can use Purchase Orders to generate bills automatically.

## Solution

### Set up automatic bill creation for Purchase Orders

1. Go to **Settings ![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/can-i-use-the-servicetitan-api-to-create-bills-image-q6gxygia.png?sv=2026-02-06&spr=https&st=2026-10-31T02%3A38%3A32Z&se=2026-10-31T03%3A38%3A32Z&sr=c&sp=r&sig=dPY8Wgfmg3DtowyyiOs7dE00MUcZUVAwIp1F%2BOYbFzE%3D)** in the top toolbar.
2. In the side panel, go to **Inventory > Configuration**.
3. On the Purchasing tab, select **Automatically create bill when PO is received**.
4. When you're finished, click **Save**.

### Use the API to create a Purchase Order

1. Access the [ServiceTitan API](https://developer.servicetitan.io/).
2. Go to the **PurchaseOrders_Create** endpoint.
3. Use this endpoint: [https://developer.servicetitan.io/api-details/#api=tenant-inventory-v2&operation=PurchaseOrders_Create](https://developer.servicetitan.io/api-details/#api=tenant-inventory-v2&operation=PurchaseOrders_Create)

### Receive the Purchase Order

1. Mark the Purchase Order as received in ServiceTitan.
2. The system will automatically create a bill based on the PO.

By following these steps, you can use the ServiceTitan API to create bills indirectly through Purchase Orders.
