Gusto Integration

From your

Applies to ,


When I Work integrates with Gusto (formerly ZenPayroll) to make managing employees and exporting payroll painless. The integration allows you to:

  • Sync employee names
  • Send timesheets from When I Work to Gusto
  • Send When I Work job positions and pay rates to Gusto
  • Send PTO and sick time from When I Work to Gusto


  • Your workplace must use Time Clock & Attendance to set up payroll integrations.
  • When I Work and Gusto use different methods to calculate overtime, which can cause discrepancies between the two systems.
  • To send paid time off (PTO) and sick hours from When I Work to Gusto, the Gusto Time Off Requests feature must be turned off.
  • When I Work holiday hours are not sent to Gusto. If your employees’ timesheets contain holiday hours, a message appears displaying the number of holiday hours that will be ignored.
  • The integration does not support contractors or salaried workers in Gusto.
  • If you have multiple Pay Schedules configured in Gusto, you can only sync one of them with When I Work.
  • The integration does not support multiple companies in Gusto. There can only be one company in your Gusto account.

Before you begin

Make sure all of your employees are fully onboarded in Gusto. If you attempt to export payroll before employees are onboarded, payroll export will fail and display an error:

Employees with ids <ID> ,<ID> are ineligible for this payroll

Setting up the Gusto integration

Step 1: Verify accounts

Before you get started you’ll want to double check a few things to make the integration works properly:

  1. Make sure you have a valid Gusto account. You can learn more about Gusto at their website.
  2. Make sure you have the Attendance feature enabled on your When I Work account.

Step 2: Check pay periods

Make sure your pay periods are the same in both Gusto and When I Work.

Viewing pay periods in Gusto

To view your pay periods in Gusto, click on the Company menu item on the left and look under the General Information section. If the pay periods are incorrect, you can modify your pay periods by clicking edit.


For more details on how to set up Pay Periods rules in Gusto visit their website.

Viewing pay periods in When I Work

To view your When I Work pay period dates, click Clock Attendance and view the pay period dates on the left.

If you haven’t yet set up your pay periods, the system will guide you through the process. If you need to modify your pay periods, you can adjust them in the Pay Period box, or go to your account settings and modify the way your pay periods are set up there.

Step 3: Set up employees

Make sure that your employees are set up properly in Gusto.

Match employees across Gusto and When I Work

  • If you currently have employees in both systems, make sure their email addresses, first names, and last names match (case sensitive). The integration will help you match names together, but this makes the process easier.
  • If you have employees in Gusto that aren’t in When I Work, the integration will sync them over to When I Work for you.
  • If you have employees in When I Work that aren’t in Gusto, you’ll need to manually add them to Gusto before syncing or the system will tell you that you need to add employees to Gusto.

Set up vacation and sick time

If your employees are able to use Paid Time Off (PTO) or Sick Pay, make sure that:

  • Vacation and sick pay rules set up in Gusto and applied to the employee in their employee details.
    If vacation and sick policies are not set up in Gusto, your sync will fail if there are sick or PTO hours in When I Work.
  • The Gusto Time Off Requests feature is turned off.
    PTO hours will not transfer if this feature is enabled in Gusto.
