# Can't add a service or material to a POS invoice

![](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/anvil-wrench.png) Troubleshooting **Role:** Administrator · Office Admin**Area:** Invoicing, Point of Sale (POS), Pricebook · All versions

> [!NOTE]
> **Note:** This feature requires the **Point of Sale** module to be enabled and the **Edit point of sale settings** permission. Contact Technical Support to enable the module, and your account administrator for the permission.

## **Where you see it / Where you fix it**

**Where you see it:** The POS invoice (the item won't add)

**Where you fix it:** The item's Pricebook section (**Settings > Pricebook > Materials, Services, or Equipment**) to confirm its category, and **Settings > Invoicing > POS Locations** to add that category

## **What you're seeing**

You're trying to add a task or material item to a Point of Sale (POS) invoice, and it won't add. The item exists in your Pricebook, but it isn't available to select on the POS invoice.

> [!NOTE]
> **Note:** Equipment cannot be sold on a POS invoice. A POS location can only include material and service categories, so equipment items never appear as options on a POS invoice. If you need to sell an equipment item through POS, the documented workaround is to create a duplicate Service item based on that equipment, assign it to a category that is on your POS location, and sell the Service item instead.

## **Why this happens**

**Reason 1**

**The item's Pricebook category isn't on the POS location — or the item has no category.** Tasks and materials can only be added to a POS invoice if their Pricebook category has been added to the POS location. If the item's category isn't on the POS location, or the item has no category at all, the item can't be added there.

## **How to fix it**

### **1****Add the item's Pricebook category to your POS location(s)**

Use this if a task or material won't add to a POS invoice.

1. Go to the navigation bar and click **Settings > Pricebook**, then open the section that matches your item: **Materials** or **Services**.
2. Find the item you're having trouble with, click **Actions** (the icon at the end of the row) and select **View/Edit**, then note its category in the **Categories** field. If the item has no category, assign it to one.
3. Go to **Settings > Invoicing > POS Locations**.
4. On the **POS Locations** screen, open an active POS location and check its **Pricebook Categories** list for your item's category.
5. If the category isn't listed, open the location for editing, add the category in the **Pricebook Categories** field, and click **Save**. Note: There is no "select all" option, so add each category you need individually.
6. If you have more than one POS location, repeat step 5 for each location.
7. Try adding the item to the POS invoice again.

> [!NOTE]
> **✓ Done ·** The item can now be added to the POS invoice.

> [!NOTE]
> **Note:** You cannot add discounts or fees on a POS invoice, and POS invoices do not apply rate sheet or client-specific pricing rules. If you need those, build a standard price into the item.
