Starting a new QuickBooks Online file is where most setups quietly go wrong. A missed subsidiary ledger, a wrong date, or a messy opening balance equity account can haunt the books for years.

Using a "Get Great Guitars" practice scenario, this course walks you through a clean workflow for setting up a new QuickBooks Online 2026 company file. Instead of importing every customer, vendor, and transaction from a prior system (and inheriting all of its errors), you'll learn how to bring across only what you need — the balance sheet accounts as of the cutoff date, with full subsidiary ledger detail where it matters.

You'll work through each major account one at a time and watch how QuickBooks defaults to the right form for each one. The course also covers payroll setup decisions and sales tax configuration, then closes with a verification session to confirm everything ties out before you enter a single current-period transaction.

Who this course is for: Bookkeepers, accountants, accounting students, small business owners, and QuickBooks ProAdvisors setting up a new QuickBooks Online file or migrating from a prior system.
