A change order is used on a recurring service when there are additional services needed while a vendor is onsite for a recurring visit. Should the vendor need to approve additional funds, they will submit a change order.
You will see this change order listed on your Worksmith homepage under the section Open Change Orders. Drop down this section and click on the recurring request that is listed. The status may be listed as Completed, but that's OK. You can still view the change order for the specific visit.
Once on the recurring service page, scroll down until you see a check box labeled Show jobs with open change orders and check the box. This will filter the recurring service visits to the one containing a change order. Click the right arrow to see a pop out of the details. On this pop out, there will be a link to View Open Change Order. From there, review the existing price and new price and select to approve or decline the change order.
