Sponsors approve proposals they can read before the meeting. This one page project proposal template leads with the amount and the decision wanted, then shows the baseline problem, the alternatives considered, a cost table with calculations, a spend chart, a contingency note and a month-by-month timeline with named owners.

The sample follows Kestrelby Group asking for £100,000 to cut invoice rework from 22% to 5%: 140 hours a month lost today, payback in 19 months, six months to deliver and 12% held as contingency. Replace the ask and amount first, then your own baseline figures, real alternatives including doing nothing, your quotes, and the approver and decision date.
