Payroll Calculations

Manage Payroll Efficiently

ArboStar's "Calculations" section provides a powerful tool for efficient payroll processing, ensuring accurate and timely employee payments. Its user-friendly interface and robust functionality facilitate the tracking of employee hours, calculation of overtime pay, and generation of detailed pay stubs. This feature streamlines the process of updating employee information by eliminating the need for individual edits of each employee's pay rate or hours worked.

Navigate to "Personnel""Payroll""Calculations".

The list is filterable by time period. Users may navigate to previous or subsequent payroll periods using the directional arrows or select a specific period from the calendar. To access the desired time period from the calendar, click the "Date" field. From the calendar, you can select the time period or click "Today" to access the current payroll information.


Users can modify or input an employee's standard and overtime hours, as well as their hourly and overtime rates. Furthermore, expenses can be added. The salary will be calculated automatically based on these parameters.

To edit regular hours, hourly rates, overtime hours, or overtime rates, click on the value and input the new hours or rate in the corresponding fields.



The Add Expense feature allows you to log, categorize, and track expenses directly in the system. This helps maintain accurate financial records, streamline reporting, and ensure proper expense tracking for each job or project.

  • Date - Select the date of the expense. 

  • Select Payment - Choose the payment method used for the expense (e.g., Cash, Credit Card, Bank Transfer). This helps with bookkeeping and reconciliation later.

  • Tax - Select the applicable tax rate for the expense. The default system tax will be pre-selected but can be changed if needed.

  • Amount - Enter the total amount of the expense before tax (if tax is applied).

  • No TAX Expense - Check this box if the expense is not taxable. This will override the tax field and save the amount as tax-free.

  • Description - Provide a short description or note about the expense (e.g., "Fuel for truck," "Equipment repair"). This helps in reporting and identifying expense categories.

  • Expense File (Optional) - Upload a file or receipt image associated with the expense. This is useful for recordkeeping and proof of purchase. Click Choose File to attach a document or image from your device.


Once you've filled in all the info, hit the "Approve" button to save your changes and confirm the payroll. You can also select multiple employees at once by checking the box next to their names (or the one at the top to select everyone), then click "Approve Selected".

To undo any manual modifications, please select "Actions" and then choose "Cancel."
