Can I convert 2 company folders into one

I can help you with merging your vendor list, @Terri56.

Yes, you are permitted to transfer your vendor list from Company 2 to Company 1. Simply export the vendor list from company 2 and import it into company 1. You can then merge identical vendors.

To export your vendor list from Company 2:

1. Go to the Gear icon (⚙) and choose Export Data.
2. Click the Lists menu.
3. Toggle the slider to green for Vendors.
4. From the Reports menu, toggle the slider to gray to remove reports.
5. Click the Export to Excel button at the bottom.

Once done, check out the following article on how to format your vendor list and import it successfully to company 1: Move your lists to QuickBooks Online. It'll also guide you on fixing errors you'll possibly encounter when importing lists. 

Then, once you notice some duplicate vendor accounts, refer to the following article on how to merge their profiles to keep one vendor account: Merge duplicate accounts, customers, and vendors in QuickBooks Online. It'll help you choose what profile to keep and then edit the display name to merge it successfully. QuickBooks moves past transactions from the duplicate to the vendor you want to keep.

In case you want to add your vendor balances in company 2, here's how you'll add unpaid bills you owe the vendor: Manage outstanding balances for customers and vendors in QuickBooks Online.

It is possible but you will spend time or money to make it happen.
