When selected the product or service why does it disappears from the spreadsheet

Glad you've joined us here today, @ivison-kurt.

Let's get your product or service item appeared on spreadsheets. Open your QuickBooks Online (QBO) account using a private browser or an incognito mode. This is to determine if this is a cache-related issue. The process depends on the browser you’re using.

Here's how:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + N
• Safari: Command + Shift + N   

Then, select a product or service items and check to see them in your spreadsheet. If it's working fine, go back to your regular browser and clear the cache. This process will optimize the QBO performance. If you continue to get the same result, use a supported browser.

Here's an article that'll help you manage customer-related tasks. It contains topics with articles that you can choose from: Topics about your company's income and customers.

Reach out to me again if you have other questions with product or services. I’ll get back to help. Have a great day ahead.
