When moving QuickBooks Desktop to Online, eligible data such as customers, vendors, chart of accounts, invoices, bills, payments, estimates, sales receipts, journal entries, inventory, attachments, and certain payroll information can transfer. However, some features and settings may change or require manual setup. Intuit notes that data transfer depends on the Desktop version, Online plan, and specific feature. Review transferred accounts, transactions, reports, payroll, and inventory after migration.
