When I tried to renew my subscription, I have opened new company by mistake!!Can I marge the new company with the old one with that subscription?Or what Can I do?

Hi there, @info-qannas-app. 

I'll make sure that you'll be able to renew your subscription in QuickBooks Online .

In QuickBooks Online (QBO), you're only allowed one company per subscription. You can cancel your QuickBooks Online subscription and contact our Support Team for a refund. 

Here's how:

1. Click the Help (?) icon at the top.
2. Type Talk to a human.
3. Enter your issue or question on the What can we help you with box.
4. Choose I still need a human.
5. Select the Start messaging option.

To ensure you can reach out to our agents, please see our support hours.

I’m including a couple of links with great info on how to move or merge data files and lists in the company you want to keep: Merge data files; Move lists to QuickBooks Online. This will help combine the data as quickly as possible.

Don't hesitate to place a comment below if you have other questions in mind. I'll get back to you as soon as I can.
