Bands instead of a cliff
Each band pays its own rate on the revenue inside it. The curve bends upward gradually, so the incentive is smooth rather than concentrated at one threshold.
Show the band live
Tiers only change behaviour if reps can see which band they are in and what the next deal pays. That is what the Prowi app does.
Keep it to three
Three bands cover almost every case. Five bands is a spreadsheet, not an incentive.
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.
