A binary reward
Nothing at 99%, everything at 100%. That clarity is the strength and the weakness: it focuses attention on one number and it invites sandbagging around the threshold.
Pair it
On its own it rarely carries a plan. Combined with a flat rate or tiers it becomes the exclamation mark at the end of the period.
Budgeting
The cost is known in advance: bonus × number of reps who hit. Finance likes this model for exactly that reason.
In Prowi
Create the plan, pick the measurement point and period, set the rule, assign it to roles. From there every closed deal in your CRM is priced live, the rep sees it in the app, the manager approves, and finance exports the file. When data changes, the correction follows automatically.
