Hello there, @hassansaeed.
The option to import sales receipts from POS is unavailable in QuickBooks Online. However, you can manually enter them into the program to keep track of your transactions.
You can also look for a third-party app inside QuickBooks that will help you with this process. Just log in to your account and search for the app from the Apps menu.
I'll surely take note of this suggestion for future updates. For more details in handling customer transactions, refer to these links:
