I am getting rid of an old computer that was running QB 2013 for my old business. I know you can make a backup of your files, but how do you export/consolidate all your expenses, invoices, records, etc in case you get audited? Or for any multitude of reasons, really. I have 4 years I need to backup.
QB 2013 is unsupported, I'm assuming, and wouldn't be able to open it with new mac OS's.
I'd be glad to help share some information about making a backup file from your old business.
QuickBooks will save your backup data as a disk image file, you can restore the company file and attached documents by clicking the .dmg file. You can check out this article for more information: Restore a backup (.dmg) in QuickBooks Mac.
It'd be best if you make two backup copies from the old business. This way, you'll have an extra copy just in case.
As always, you can contact our QuickBooks Mac support if you need further assistance in going through the steps.
