Learn how to open QuickBooks Desktop and Online files, find your company data, and troubleshoot common opening errors for seamless access to your finances.

Opening your QuickBooks file should be a simple task, but different versions, file locations, and occasional errors can make it surprisingly difficult. Getting to your financial data quickly is the first step in any accounting task, whether you're a business owner checking daily sales or a CPA beginning a client engagement. This guide provides clear, step-by-step instructions for opening both QuickBooks Desktop and QuickBooks Online, finding your company file, and troubleshooting common issues you might encounter along the way.
QuickBooks Desktop is a locally installed software, which means you're dealing with two key components: the application itself and your company data file. Many user issues arise from confusing the two. The application is the program you install on your computer (the green ‘QB’ icon), while your company file is the separate file that holds all your financial data (typically ending in .qbw). You must first open the application to then open your company file, or you can open the file directly.
Here’s how to launch the QuickBooks Desktop application on your machine.
There are several common ways to start the QuickBooks Desktop program in Windows:
When you open the application without a specific company file, you will be greeted with a "No Company Open" window. This window is your hub for accessing or creating your business's financial records.
The process for Mac users is very similar:
Once the QuickBooks application is running, or if you prefer to open your data directly, you need to locate and open your company file. This is the file that contains all your invoices, bills, reports, and chart of accounts. These files always use the .qbw extension.
When you start QuickBooks Desktop without choosing a file, the "No Company Open" screen gives you several choices. To open your main data file, follow these steps:
C:\Users\Public\Documents\Intuit\QuickBooks\Company Files.If you know exactly where your company file is saved, you can skip opening the application first. Just navigate to the folder with your .qbw file and double-click it. Your computer's operating system will automatically identify the file type and launch the corresponding QuickBooks Desktop application to open it. This is often the fastest way to get to work if your files are organized.
If you already have a company file open and need to switch to another one, you don't have to close the program.
If you are setting up books for a new business, you'll need to create a new company file from scratch. It's a guided process that helps you establish your accounting foundation.

QuickBooks Online (QBO) operates entirely differently from its desktop counterpart. Because it's a cloud-based service, there is no .qbw file stored on your computer. Your data is housed securely on Intuit's servers, and you access it through the internet. This allows for access from any device, anywhere.
This is the primary way most people use QBO. It's simple and requires no installation.
For accountants and ProAdvisors with multiple clients, after signing in, you will be directed to your QuickBooks Online Accountant dashboard. From there, you can select which client's company file you wish to access.
For users who prefer a more dedicated experience outside of a busy browser, Intuit offers a desktop app for both Windows and Mac.
The app is essentially a specialized web browser built only for QBO. Its benefits include staying logged in more reliably, using keyboard shortcuts, and keeping your accounting separate from your other browser tabs, which helps maintain focus and improve workflow.
Even a straightforward process can run into trouble. Here are some of the most frequent issues and how to resolve them.
This happens to everyone at some point. Try these steps in order:
C:\Users\Public\Documents\Intuit\QuickBooks\Company Files.This error happens if you try to open a file—for example, one from a client or a newer computer—with an older version of QuickBooks Desktop. QuickBooks data files are not backward-compatible. You cannot open a 2024 file with QuickBooks 2022. The only solution is to open the file with the same version or a newer one.
These errors often signal file corruption, network issues, or problems with multi-user mode. Here are a few first steps:
If these steps don't work, you may need to restore from a backup file (a .qbb file), which is a "snapshot" of your company data that you can use to recover your main file.
Whether you use the local power of QuickBooks Desktop or the flexible access of QuickBooks Online, opening your account is the first step in managing your finances. By knowing where to find your files and apps, and understanding how to troubleshoot common hiccups, you can get to your financial data quickly and confidently.
