**Marlin GTX** enables structured job management from booking through to final invoicing using Work Orders.

Work Orders record customer, vehicle and product details and control the full job lifecycle, providing:

  • Permanent job records including parts, labour and timestamps
  • Stock allocation and availability control before invoicing

Work Orders can be added directly to bookings, by clicking the Work Order button at the bottom of the Business Planner booking screen.
