Why my payment is 36000 rs.

Hi there, vvnakshar.

Welcome to QuickBooks Community, vvnakshar. I'll share information about the billing amount of the subscription in QuickBooks Online.

There are several reasons your monthly charge increased to 36000. One of those is, you may have availed of the discounted monthly subscription and it had expired, so you're charges now with the regular price. To further check and verify the payment being charged, I suggest contacting our QuickBooks Support Team. 

Here's how:

1. Log in to your QuickBooks Online (QBO) account.
2. Go to the Help menu.
3. Type your question in the search box below or click on one of the following frequently viewed topics.
4. Click No, I still need help.
5. Select Contact QuickBooks Support.
6. You'll be routed in the Choose a way to connect with us page.
7. Choose Chat or select how you want to contact them and fill in the information.

I'm also adding different articles to further guide you in effectively managing your business using QBO: Help guide for QuickBooks Online. It contains topics about advanced accounting, banking, and payments.

This should point you in the right direction. I'm always here if you need further assistance in your subscription. Have a great rest of the day!
