# Book it and send it to an engineer

Put the job on an engineer's calendar in the planner and send it to their phone.

1. Open **Planner**. Your new job is in the **Unassigned** list.
2. Drag it onto an engineer at the time you want. Or select **Book** on the job and choose the date, time and engineer.
3. To put it on their phone straight away, tick **Send to the engineer's phone now**.
4. Select **Book**.

If the engineer is already busy, on leave, or missing a skill the job needs, Sustainable ERP shows the clash before you save. You can still book if you give a reason.

## Sending a whole day at once

Most offices book during the day and send everything for tomorrow in one go. On the planner, go to tomorrow and select **Dispatch day** on each engineer's row. Their visits appear in the app straight away.
