Products were working but have stopped populating on the invoice

Hello, NLawell. I understand how crucial it is for your workflow to have products populate seamlessly, especially when managing multiple transactions. It can be challenging when things don't work as expected, but I'm here to help you fix this quickly.
 
Before anything else, I'd like to ask where you set up your items. This additional detail will help me better understand your situation. 

In QuickBooks Online, products should be added to the Product & Services page rather than the Chart of Accounts. It ensures proper inventory management and accurate sales tracking.
 
The Chart of Accounts is a comprehensive list of all accounts used by your business to categorize financial transactions.

If you've configured this on the designated page, let's verify its status. If it's inactive, it won't appear on your invoice. Please follow these steps:
 

1. Head to the Sales menu, then Products & Services. 
2. Locate your preferred item. If it's not on the list, click the Filter icon. 
   In the Status column, pick Inactive. Apply it. 
3. Press the Make Active option to have it re-added to the lists.
    

I'm adding a visual sample for your reference. 


When you create an invoice, you can write the first letter of your goods and select it to populate. I have tested this on my end, and I was able to do it.

If you are referring to the Product/Service column on the Invoice page, please ensure the settings are toggled on to enable it. Please refer to the attached sample for clarification.

In case everything is set up correctly, but the issue persists, let's troubleshoot this. An accumulation of historical data can lead to unexpected behaviors. 

Let's open your account and create an invoice using an incognito window to eliminate the possibility of a webpage issue. 
 

Here are the following keyboard shortcuts:
 

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

Once the product populates, return to your regular browser. Then, clear your cache to start afresh. If the issue remains, consider switching to other supported browsers installed on your system.

For future reference, once you receive a payment from your customer, you can record it in QuickBooks to mark the invoices as paid.

I hope the steps above help you get your products to populate smoothly again. If you encounter further challenges, hit the Reply button below. Your successful invoice management is our top priority, and I'm committed to ensuring you have a positive experience with QuickBooks Online.
