Hi Debit n Credit,

Welcome to the Community! Thank you for reaching out, I'd be happy to provide some assistance with moving your transactions to your new account.

To combine your two companies in QuickBooks Desktop Pro 2020 and transfer transactions to a new file, I recommend following these steps:

• Backup Your Existing Company Files:
  Before making any changes, backup both of your existing company files. This ensures you have a safe copy in case anything goes wrong.

1. Export Transactions from Company A:
    a) Open Company A in QuickBooks Desktop Pro 2020.
   b) Go to the File menu and select Utilities.
   c) Choose Export and then select the Lists to IIF Files option.
   d) Export relevant transactions such as bills, payments, invoices, and credit card charges.
    
2. Import Transactions into Company B:
   a) Open Company B (the new file) in QuickBooks Desktop Pro 2020.
   b) Go to the File menu and select Utilities.
   c) Choose Import and then select the IIF Files option.
   d) Import the IIF files you exported from Company A. Map the fields correctly during the import process.
    
3. Review and Adjust:
   a) After importing, review the transactions in Company B.
   b) Ensure that opening balances are correctly set for both companies.
   c) Make any necessary adjustments to match the data accurately.
    
4. Reconcile and Verify:
   a) Reconcile your accounts in Company B to ensure everything balances.
   b) Verify that all transactions, balances, and opening balances are accurate.
    

• Consult with an Accountant:
  It’s advisable to consult with an accountant or bookkeeper to ensure compliance and accuracy. They can guide you through the process and provide specific advice based on your unique situation.

Remember to take your time during this process and double-check everything to avoid any discrepancies. If you encounter any issues, consider using third-party tools as mentionned in the reply above.
