# Project line options

Settings for project lines - descriptions, ETAs, dimensions, tax calculation, suppliers on lines, and the returns workflow.

Choosing a supplier for every product you add to a project slows quoting down, and a line with no supplier can't be ordered. The **Project Lines** settings in System Settings decide which supplier a new line takes, what each line shows, and which workflow returned projects follow.

### Before you start

You'll need the **Organization Setup** permission, in the **Settings** permission group.

### How to change your project line options

1. In the main menu, go to **Settings** > **Organization Setup**.
2. Select the **Configuration** tab.
3. Under **Project Lines**, change the settings you need.
4. Select **Save**.

You see "System Settings saved successfully".

### What lines show

* **Show both project line descriptions and line notes:** The description and line notes are shown together, in one "Description & Line Notes" column.
* **Enable ETA on projects:** Adds an **ETA** (expected arrival date) column to project lines. What you enter there is also shown on your PDF documents.
* **Use product and box dimensions:** Uses product and box dimensions for packing and courier quotes. On by default. Turn it off if your courier doesn't need dimensions. With a courier app installed, it also shows **Box Dimensions** in the menu. See [Box Dimensions](/central/order-management/settings/box-dimensions.md).
* **Enable On Demand Tax Calculation:** Tax is worked out by an installed app from the App gallery that calculates tax. It has no effect without such an app.

### Suppliers on lines

* **Require Supplier for Project Lines:** You can't add a product without a linked supplier to a project. You're told why.
* **Use Default Supplier:** A new line takes the product's default supplier straight away. If no supplier is marked as the default, the first linked supplier is used.
* **Project Fallback Supplier:** The supplier given to a line when no other supplier applies.

When **Use Default Supplier** is off, which is the default, you're asked to choose a supplier when a product has more than one. A line added without asking, such as from an import, takes the cheapest supplier.

**Example:** A chair is linked to two suppliers, and "Office Direct" is marked as its default. With **Use Default Supplier** on, adding the chair to a project gives the line "Office Direct" at once. With it off, you're asked which of the two suppliers to use.

### Returns

**Returns Workflow** is the workflow given to projects created with **Return this Project**. Until you choose one, nobody can start a return. You can also choose it in the Workflow Manager.
