The following areas of the Booking/Invoice screen should be observed in particular.

Branch
Allows you to track jobs and assets across multiple depots.
Invoice Category
Allows you to categorise the job for filtering and reporting.
Delivery/Pickup Details > Zone
Use the Zone to automatically calculate delivery and service fees based on the local council area.
Mode
General rule of thumb, if it's a cash (pay up front customer), create as a new Invoice. If it's an account customer (pays final payment in arrears) then create as a new Booking.
Booked From
Enter the scheduled date the customer would like the hire asset delivered.
Booked To & TBA
Enter the estimated date the customer will be finished with the hire asset. Check the TBA box if the end date is unknown.
Hire Asset
Select a hire asset first. You need to track your hire assets and under which assets are on what job site.
Delivery Fee
Ensure you are charging the relevant delivery fee for the zone you are delivering to and the size of the hire assets being delivered.
Service Fee
Ensure the service fee is initially 0 Qty/Units. The quantity will automatically increase as scheduled onsite services are completed.
Unit & Quantity
Ensure the correct Unit and Qty/Unit is entered for all items. Unless you are charging out hire assets by the day or week, the Unit will normally be Each.
Price
Ensure the price is correct, taking note of whether the Invoice is in exclusive or inclusive tax mode.
