What Types of Files Can Be Uploaded to QuickBooks

QuickBooks supports a variety of file types that make it easier for businesses to import data, reports, and transactions efficiently. Commonly supported formats include .QBO (bank feeds), .IIF (list and transaction data), .CSV (spreadsheet imports), and .QBB/.QBW (QuickBooks backup files). These files allow users to bring in data like invoices, expenses, payroll, and chart of accounts directly into QuickBooks.

However, managing multiple uploads from banks, payment systems, and CRMs can quickly become complex — especially when data formats don’t match or files fail to import correctly. That’s where QBIS Sync helps simplify your workflow.
