With Go Carrera Change Orders, all types of change orders can be initiated and accepted quickly and easily. A change order deduction is a deduct from an original Work Order item, an additional change order is an added cost to an original Work Order item, and a change order item is a new line item added to the Work Order. A change order can be initiated from a company or installer, and once the other party accepts the change order, the items can then be removed or added to the invoice. If a mistake was made on a change order, the party that initiated the change order may void it as needed. Once a change order is initiated, there is a 72-hour response period before it gets auto approved.
