How to round off the timings displayed on an invoice

To round off the timing displayed on an invoice to the nearest hour, go to Me (in the top right corner) - Business Settings - Billing - Check the box for Round off extra time of every duty while displaying on invoice - click on Save

If the duty slip has extra hours listed as 32:45 hrs, it will display the hour rounded off, which is 3300 hrs when the invoice is generated. Similarly, if the duty slip has extra hours listed as 3215 hrs, it will be rounded off and displayed as 3200hrs which is the nearest hour.
