Thank you for the prompt reply. Allow me to join the thread and handle your query about entering transactions by batch, @todjenhog.

The feature you described in your initial post is Batch enter transactions. This is a feature that's exclusive in the QuickBooks Desktop (QBDT) Accountant and Enterprise versions. 

What my peer @RCV stated above is correct for your situation. You can utilize IIF files to transfer transactions from one company file to another. Other than lists, it can import credit card transactions as well. 

Here's a list of every type of transaction you can import with this feature: 

• Account beginning balances
• Cash sales to customers
• Checks
• Deposits
• Invoices
• Account transfers of funds
• Vendor bills
• Cash refunds to customers
• Credit card transactions
• Estimates
• Payments from customers
• Vendor bill refunds
• Credit card refunds to customers
• Credit memos to customers
• General journal entries
• Purchase orders

If you want to go a different route, you can also use a migration tool like what @Fiat Lux - ASIA stated above. Or, you can take a look at this page: Apps for QuickBooks Desktop. It's a complete list of third-party apps you can link to your QBDT company.
