Hi there, @Kishorkp.
Thanks for looping into this post. I can share some information about the invoice number in QBO.
QuickBooks has a sticky setting feature which will remember the previous information and continue to use it (unless changed). In your case, you will have to manually change the invoice number when creating an invoice to different locations.
I'll help you pass along your feedback to our developers. You can visit the QuickBooks Online Feature Requests website to post your request. I'll do the same on my end for the request to get more votes. You can also do that within QuickBooks by clicking the Gear icon and choosing Feedback.
For additional information about customizing invoices, you can refer to these articles:
Drop me a comment below if you have any other questions about invoices. I'll be happy to assist you.
