Hello, @Ganapathi. I've got some information you need when resubscribing to QuickBooks Online.
QuickBooks recently announced that access to QBO for existing customers in India had been extended until 30th April 2023. That said, no new sign-ups to QuickBooks products in India will be accepted. Thus, you're unable to resubscribe to your account.
However, you can download your data before April. That way, you can still save a copy of them to your local hard drive. Here's how:
Go to the Gear or Settings icon from the toolbar, then select Export Data.
Proceed to the List or Reports tab, then select what reports or lists you want to export by toggling the slider.
