SUSPECTED BUG (QB Singapore): Saved invoice with selected Product codes linked to specific revenue A/Cs- it posted as a negative expense in an unrelated head of account

This is unusual behavior, anjalisaini.

The outdated stored cache in the browser can affect the performance of QuickBooks Online. Let's access your account via a private window to resolve this issue.

Here are the keyboard shortcuts: 

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

Once signed in, create invoices using the product codes that cause the issue. If it works, I'd recommend clearing the browser's cache to avoid unexpected problems in the program.

You can also use other supported browsers as alternatives if private browsing doesn't work.

If the issue persists, I'd recommend contacting our QuickBooks Support Team. They're equipped with tools to investigate the cause. It'll also allow them to submit a ticket to our engineering team to alert them about the issue if necessary.

Additionally, I've added an article that'll guide you in personalising your invoice templates. Doing so helps you add the info that matters to your business: Customise Sales Forms.

Please keep us posted if you need help creating and managing your sales transactions and items. We're always here to assist you.

Will let you know if it recurs. 

Is there an option to add LATE FEE and interest to the invoice without raising a SEPRATE invoice ? In the USA version we have that option. 

Great idea you have there, @anjalisaini. I'll share some updates about the late fees in QuickBooks Online (QBO).

At the moment, there are no options to add the late fee setup in QBO International. I'd suggest sending a feature request directly to our Product Development team. They are always open to any suggestions as this can help us make QuickBooks better. 

Here's how:

1. Go to the Gear menu and then select Feedback.
2. Type in your feature request in the description box.
3. Once done, click on Next.

You can also track the feature requests through the Customer Feedback for QuickBooks Online website.

In addition, you can view our Community help articles for QuickBooks Online International. It has topics with articles, videos, and posts with our Community users to guide you along.

Know that you can always reply to this thread if you need help with invoices or with late fees. I'll be around for you. Take care and have a good one.
