We can transfer the customer names and re-enter their transactions, @gorgevic. I'll ensure we can achieve this in a breeze.
To start, let's export these data as lists to Excel and then import it to your new QuickBooks account. I'll show you how:
- Go to the Gear icon and select Export data.
- Click the Lists tab and switch off Employees and Suppliers.
- Tap Export to Excel.

After that, follow these steps to add your customers' names to the new one:
- Go to the Gear icon and select Import data.
- Choose Customers.
- Browse the folder where you save the exported list and pick the Excel file.
- Map your data and click Next.
- Adjust your data if necessary and tap Import.

We can also import transactions such as invoices, credit notes, and sales receipts from a CSV file. However, we're unable to Export them. That said, I recommend looking for a third-party app that suits your needs.
Here are some references that can help you with downloading your data from the old QBO account and importing multiple invoices to the new company:
