Why does QBO calculate a daily rate of pay by the number of days in that particular month rather than an average of the number of days in the year?

Hi Valerie,

QBO will calculate the pay based on the average number of days in a year if the employee's pay type is Salary. You can check your employee's pay type and change it to salary.

If you're using the QuickBooks Advanced Payroll, you may have set up the pay rate to per day. Please check this out: https://intuit.me/2H0atHv

Let us know if you have additional questions with your payroll.
