Welcome to the Community, Zulqarnain.

I appreciate you for switching to QuickBooks Online. Setting your invoice numbers to start from 10301 in QBO is straightforward. I'll guide you through the process.

Here's how to do it:

1. In the upper left corner, click the +New button.
2. Choose Invoice under the Customers section.
3. In the Invoice no. field, enter 10301.
4. Select Save and close.
   
   

The next invoice will automatically follow the sequence from your customer number. I've included a screenshot for your reference.
