If you want to use a single log in credential for multiple companies, we can follow the consolidation process. You an follow the detailed steps in this article: Sign in to multiple QuickBooks Online companies with one user ID.
Note that you can add multiple companies to your QBO account: Create or add another company.
If the merging process you're referring to is to move the company data from one QBO to another, we don't have a direct way of doing this. We'll do the following process:
- Export lists from your current QBO account.
- Import it to your other QBO account.
- For the transactions, you can either:
• Connect your bank account and import/manage the transactions.
• Manually record the transactions from the account.
- Cancel the QBO subscription you're not going to use.
You can follow this article for the detailed steps: Move your lists to QuickBooks Online.
Another option is to search a third-party application online that can directly do this.
We'll be right here if you need further assistance with this. Have a great day!
