Converting Peachtree to QuickBooks: What Carries Over and What Does Not
A practical guide to moving from Peachtree (Sage 50 US) to QuickBooks: which lists and balances transfer, which transaction details are lost, and how to plan the cutover.
When you convert a Peachtree company to QuickBooks, the core lists and opening balances carry over. That means your chart of accounts, customer list, vendor list, employee list, and item list all transfer. Opening account balances, trial balance figures, and historical balances for customers and vendors come across as well.
What does not carry over in full detail is the transaction history. Individual invoices, bills, checks, and journal entries from prior periods generally do not migrate line by line. Instead, QuickBooks receives summarized opening balances that represent where those historical transactions left each account. The result is a clean starting point, but not a period-by-period replay of your old books.
What you lose when the detail does not migrate
Once the conversion is complete, you will not be able to open a prior-year invoice inside QuickBooks and see the original line items, dates, and payment links as they appeared in Peachtree. The audit trail resets at your conversion date. If you need to report on prior-period detail, you keep the Peachtree company file accessible for reference and historical reporting.
This is the single biggest adjustment for teams switching over. Your day-to-day work happens in QuickBooks going forward. Your historical record stays in Peachtree, read-only, for lookbacks and reconciliations against old statements.
Choosing your cutover date
Most businesses convert at a natural break: the start of a fiscal year, the start of a quarter, or right after a year-end close. Converting at year-end is usually simplest because your balances are clean, your reconciliations are current, and you are not splitting a busy period across two systems.
If you convert mid-year, the opening balances QuickBooks receives need to reflect every transaction posted in Peachtree up to that exact date. That means finishing your month-end close in Peachtree before the conversion, so nothing is left half-posted.
What about Peachtree custom fields and job tracking?
Peachtree custom fields on customers, vendors, and items do not map directly into QuickBooks. QuickBooks has its own custom field structure, and the conversion does not automatically recreate your old fields. You will need to set those up again in QuickBooks after the data lands.
Job tracking works differently between the two products. Peachtree’s job costing structure does not translate into QuickBooks’ class tracking or project system on a one-to-one basis. If job reporting is central to how you operate, plan time after the conversion to rebuild your job setup and test a few reports before you rely on them.
Multi-user access and data file differences
Peachtree stores its data in a database file that multiple users access over a network. QuickBooks Desktop uses a company file (.qbw) with its own multi-user hosting model. The way you open, back up, and share the file changes after the conversion.
QuickBooks requires the database server manager to be running on the host machine, and each workstation needs the correct version of QuickBooks installed. If your team is used to simply opening a shared Peachtree folder, the QuickBooks setup will feel different. Budget time for the IT side, not just the accounting side.
When a direct conversion is not the right move
Some Peachtree companies have years of transaction history that the business needs to keep accessible inside the active file. If that is the case, a full conversion may not be the best fit. An alternative is to bring over only the lists and current-year opening balances, leaving the deep history in Peachtree for occasional reference.
Another scenario is a Peachtree file with data damage. If your company file has corruption, missing records, or reconciliation errors, converting that damage into QuickBooks just moves the problem. In that situation, repairing the Peachtree data first gives you a cleaner starting point.
Getting help with the conversion
A Peachtree-to-QuickBooks conversion involves more than running an export and import. The mapping between the two systems’ data structures is not something either vendor documents publicly, and a poorly mapped conversion can leave accounts out of balance or lists incomplete.
