Converting Old Peachtree Data to QuickBooks: What Still Works

Moving legacy Peachtree Complete Accounting data, such as a 2006 install, into QuickBooks, and why the age of the file decides the approach.


Businesses still run old Peachtree installs, sometimes on an aging Windows machine that is the only thing keeping the books alive. Peachtree Complete Accounting 2006 belongs to that era. If you are moving to QuickBooks, the age of the data matters more than the version of QuickBooks you are heading to.

Why old Peachtree files are a special case

Modern conversion tools expect data from reasonably recent Sage 50 releases. A company file created in Peachtree 2006 predates the current Sage 50 data format, and the software that opens it may not even install on a current version of Windows.

That does not mean the data is stranded. It means the conversion usually happens in two stages: first bring the old data forward into a format that can be read, then convert that data into QuickBooks.

What you need before you start

Gather the essentials before anything else. You need the original Peachtree company folder, not just a shortcut to it, and a backup if one exists. You also need a working install of the Peachtree version that last opened the file, or a machine that can still run it.

Check that the data actually opens and that key reports, such as the balance sheet and trial balance, print correctly. A file that will not open cleanly in Peachtree will not convert cleanly either.

What typically carries over

A conversion of this kind generally moves your chart of accounts, customer and vendor records, item lists, and transaction history. How much history transfers, and how cleanly, depends on the condition of the source data and the tool used.

Older Peachtree versions stored some data differently than later ones, so expect some cleanup after the conversion. Reconciling the first month in QuickBooks against the final Peachtree reports is the best way to confirm nothing drifted.

Should you convert the history or start fresh?

For data this old, it is worth asking whether you need every transaction. Many businesses convert lists and open balances, then keep the old Peachtree install read-only for historical lookup. That shortens the conversion and reduces the risk of carrying old errors forward.

If you need full history, for tax or audit reasons, plan for a longer conversion with more verification on both ends.

Getting help with the conversion

A staged conversion of legacy Peachtree data is something our engineers handle regularly. If you would rather not resurrect an old install yourself, see our Peachtree to QuickBooks conversion service for what is involved, or read more about converting Sage 50 US to QuickBooks when your data comes from a later Sage release.

Before you commit to either route, print a full set of financial reports from the old system: balance sheet, trial balance, and aged receivables and payables. Those reports are your yardstick for proving the conversion landed correctly, and they are far easier to produce now than after the old machine gives out.
