It's great to have you here in the Community, Yee-Man. Allow me to explain the differences in functionality between the QuickBooks Online (QBO) web and the app.

The QuickBooks Online app is designed to facilitate simpler recording for small businesses and individuals. Using the app version, you can use your mobile device to enter transactions, send invoices, and track expenses easier and faster. However, it’s important to note that while the app is convenient for basic tasks, there are advanced functions and features available in the QBO browser version that you cannot access through the app. These include generating detailed financial reports and customizing sales forms, which provide a more comprehensive overview of your business’s financial health.

Additionally, you can use the QBO app to review and update bank transactions to prevent errors and discrepancies that could affect your financial statements.
