Everything here is written by our own accounting and ERP consulting team for U.S.-based small and mid-sized businesses (roughly $1M–$50M in revenue) evaluating their systems in 2026; not outside contributors guessing at what matters.

How to Enter Checks in QuickBooks Online, and When to Use Checks Instead of Enter Expenses

In this quick video I show you how to enter a check in QuickBooks Online (we used Advanced, but it will work for all QuickBooks Online editions). You will also learn when you would want to use the Write Checks function instead of the Enter Expenses function.

QuickBooks Payroll: Paying Employees for Supplemental Sick Leave (FFCRA)
