Manual Commission Adjustment:
Using Manual commission adjustment you are able to enter a bulk figure to deduct from the total commission payment. This does not recalculate any previous commissions or commission tier calculations.
Automatic Clawback with Recalculated Commissions:
By marking an opportunity as a clawback the system will recalculate the commission payment for the period that the commission was originally paid in, including the tiers and adjust the current periods by the commission overpaid.
