Let's work together to change the language in your QuickBooks Online (QBO) account, cftikklji.

In QBO, we have a feature that helps International version users modify the language to better work with their books. We support English, Chinese, French, Italian, Spanish, Arabic, Thai, Portuguese, German, Japanese, and Korean.

Here's how to edit the settings:

1. Go to the Gear icon and then select Accounts and settings.
2. Choose Advanced and go to the Language section.
3. Click the pencil icon to edit and choose Thai from the drop-down.
4. Hit Save, and then Done when you're ready.

Alternatively, you can change it on your browser. For Google Chrome, follow these steps:

1. At the upper-right of the opened browser, select the vertical ellipsis ⋮. 
2. Choose Settings, then Languages. 
3. From the Language drop-down, click Add languages. 
4. Add Thai. Then, hit Add. 
5. Click the vertical ellipsis ⋮ and then Display Google Chrome in this language checkbox.

If you use other browsers, visit the Microsoft Forms website to update the settings.

Additionally, I've added these resources that you can utilize in searching for articles to help you manage your sales transactions:

• Sales and Customers
• Invoices and Payments

Please keep me posted if you need additional assistance with the process. My main goal is to ensure this gets resolved.
