# Tags
Tags are custom labels you apply to objects in PAI to add a layer of categorization beyond what the standard fields provide. You can tag:
- **Projects** — for filtering and reporting across your portfolio
- **Budget expense lines** — individual line items in a project budget
- **Vendor profiles** — records in your vendor database
Tags are shared across the organization. Workspace Owners and Admins manage them under **Settings → Tags**.

## Tag Groups
Each tag can belong to an optional **group**, such as "Project Tags" or "Vendor Tags". Groups organize your tag list: a tag field shows the group name in front of each tag, so related tags sit together. Groups don't restrict where a tag can be used — every tag is available on every object you can tag.

## Creating Tags
### From a tag field
Click a **Tags** field — on a project's Dashboard, or a Tags cell in a table — and type in **Search or Create...**. Pick an existing tag, or create a new one from what you typed. In tables, turn on the **Tags** column first if it's hidden (**Display Options → Columns** — see [Navigating PAI](../00-Understanding-PAI/Navigating-PAI.md#working-with-tables)).
### From Settings
1. Go to **Settings → Tags** and click **Add Tag**
2. Enter a **Tag Name**, pick a **Color** (or **Random**), and optionally choose or create a **Group**
3. Click **Create Tag**
The Tags list shows each tag's **Name**, **Color**, and **Group**; change any of them in place. To delete a tag, right-click its row and choose **Delete**.
> [!warning]
> Deleting a tag removes it from every object it's been applied to across the entire workspace. This is irreversible. Rename a tag instead of deleting it unless you're certain it's no longer needed anywhere.

## Use Cases
Tags are most valuable when your standard fields don't capture a dimension you want to filter or report on. Some examples:
**Project tags:**
- Content type classification (e.g., `Automotive`, `Fashion`, `Anthem`, `Comedy`) — lets you filter Insights or the project list by the kind of work, not just the client
- Production type (e.g., `Photo`, `Production`, `Post`) — useful for segmenting financial performance by what you're actually making
- Any dimension your organization wants to track across the portfolio that isn't captured by client, campaign, or stage
**Expense line tags:**
- Tracking PO numbers at the expense level (e.g., `PO-4421`)
- Marking expenses as billable vs. non-billable to the client
- Flagging expenses that require a specific approval process (e.g., `Legal Review`, `Client Pre-Approval`)
- Categorizing by cost type beyond the standard category field
**Vendor profile tags:**
- Travel availability (e.g., `Local Only`, `National Travel`)
- Specific skills or certifications beyond the standard job title
- Availability patterns (e.g., `Short Notice`, `Weekends Available`)
- Client pre-approval status (e.g., `Approved: Acme Corp`)
- Payment preferences (e.g., `NET-15`, `COD Only`)
