Importing Time Data from Sundial into Paychex Flex



Step 1: Prepare the Time File

Export your time data from Sundial using the **Paychex Flex format**.


This format is CSV and automatically includes the following columns in the order shown:

Client ID, Worker ID, Org, Job Number, Pay Component, Rate, Rate Number, Hours, Units, Line Date, Amount, Check Seq Number, Override State, Override Local, Override Local Jurisdiction, Labor Assignment


Some of these columns may be blank depending on your setup. That's OK.

Step 3: Navigate to Payroll Import 

  1. From the Dashboard, click on 'Payroll'.
  2. Choose 'Import' or 'Payroll Data Import'.
  3. Select 'Time & Attendance Import' or 'Batch Import' depending on your account setup.

 

Step 4: Upload the File

 Click 'Browse' or 'Upload File'.

  1. Locate and select your Sundial-exported CSV file.
  2. Choose the appropriate import template (as defined in your Paychex setup).
  3. Click 'Import' or 'Submit'.

 

Step 5: Review and Confirm

After upload, review the data to ensure all hours are mapped correctly.
