I found the file that has that 3 months, but now I have 3 more months on input on an older file but missing the middle 3 months. Can I merge info? It is the same company, same clients.

merging two back up files

Hi, Tom757.


Glad you've reached out to us. I'm here to help ensure that you're able to restored the complete file transactions in QuickBooks. 


QuickBooks Desktop doesn't have an option to merge the Timesheets, checks, and invoices. The option is, you can open your old company file and export the missing transactions using Intuit Interchange Format (.IIF). Once done, you can import it to the correct file.


To export the the file, here's how: 

  1. Sign in to your company file as the Admin.
  2. Make sure you are in Single User mode.
  3. From the File menu, select Utilities.
  4. Go to Export, and click Lists to IFF Files
  5. Put a check mark next to each of the list you want to export then click OK.
  6. In the Export window:
       a.    From the Save in: drop-down, choose the location where you want to save the .IIF file (often, this will be your desktop).
       b.    In the File name field, delete the asterisk (*) and type a file name.
       c.    Select IIF Files (*.IIF) for the file type.
       d.    Choose Save.
  7. Select OK to the message that the file was successfully saved.
