Before you begin the QuickBooks Online to Sage 50 conversion process, it’s important to understand which types of data you can transfer successfully. Most businesses can migrate master records and selected transaction data through CSV or Excel files.

Understanding these data categories helps you plan the migration process more effectively and avoid unexpected issues.

You can transfer the following master records from QuickBooks Online to Sage 50 through standard import files:
