Built for the moment before you speak

Most reps do that math in their head, on the back of an envelope, or not at all. Those project exists to make that thirty seconds faster and more accurate - so the number you say out loud is one you trust.
List your open deals with their close probability and get a realistic, weighted forecast instead of an inflated raw total.
Work out your payout on a deal in flat-rate or tiered/accelerator plans. Enter the deal amount and your rate structure; see the exact commission and effective rate.
See what a proposed discount actually does to your margin - and the maximum discount you can offer before you breach your floor.
