My job has no prep or wrap. Can I just use a flat day rate?

A hot budget or a scope-only bid is a plain list of positions: one quantity, one count and one rate each. Drag a General Cost Item into the budget from the sidebar Insert tab, and the line carries Amount, Days and Fee, with no phase split anywhere on it.

Add a flat line

Open the sidebar Insert tab, Cost Items sub-tab.
Drag the first card, General Cost Item, onto the budget. Its description reads Cost Item including fields for Amount, Days, and Fee.
Drop it on a Section header to land it first inside that Section, or on the row at the bottom of the Section that repeats its total to land it last.
Name the position and fill Amount, Days and Fee. The line total is the three multiplied together: two camera operators for five days at 600 comes to 6,000.

Bill a position by the week instead of the day

The middle column's heading is the unit control. Click Days above the middle field, search the picker (Search Unit), and choose Week, Month or Hour. The heading changes to the unit you picked and the count reads in that unit, so an editor on a weekly rate and a runner on a daily rate sit in the same budget with each number exactly as agreed.

The picker lists the units your workspace has switched on. If Week is missing, the Configure row at the bottom of the picker opens Settings then Units, where units are enabled for the whole workspace. Whoever administers the workspace switches a unit on once, and everyone sees it.

Good to know

Choose the line type as you build. A flat day-rate position starts from a General Cost Item, and a position with prep or wrap starts from a Production Cost Item.
Day counts take decimals, so a half day is 0.5.
Every line sits inside a Section. Drop it onto a Section header or the row at the bottom of one.
A flat line takes AddOns, labels and references like any other Cost Item.
