On a Go Forward Basis

Dilbert comic strip -- Oct. 12, 2001. Pointed-headed Boss. "Anne, I'm going to task you with a deliverable." Anne L. Retentive. "GAAA!!! Task is not a verb!! My world is falling apart." Boss: "Tomorrow I'll ask her to timeline her project."

I've been working so hard, I'm about to have a Mariah Carey." Singer Usher.

I got this one recently:
"On a go forward basis, all outside, authorized expenses MUST be submitted and approved on the Monday before the previous quarters payable cut-off date".
How about:
"From now on, submit your expenses on time or we wont pay you for them".
