# When importing an inventory file into Xero, I get an error related to Purchase Account 300. Should I create a new account or use an existing one?

**(For: Certificate in Xero Assessment)**

If you encounter an error related to **“Purchase Account 300”** while importing an inventory CSV file into Xero, it is likely because you are not using the Demo Company.

 

This error typically occurs when the account code assigned to your inventory items does not exist or is not properly mapped in your Chart of Accounts.

 

**How to Switch to the Demo Company:**

To resolve the issue, switch to the **Demo Company** by following these steps:

1. Click on your **Organisation Name** in the top-left corner of your Xero dashboard.
2. Select **My Xero** from the dropdown menu.
3. Under your list of organizations, click **“Try the Demo Company.”**

 

*Tip: You may need to scroll down if you have access to multiple organizations.*

 

Once in the Demo Company, try importing the inventory file again.

If the error persists, feel free to contact our **Support Team** (tutor@thecareeracademy.com) for further assistance — we're here to help!
