How commissions are calculated
Smile calculates commission on the pre-tax value of a charge and raises commission only on the value of payments made against an invoice, not the total value of an invoice. For example, a $100 invoice that contains 10% GST was settled with a $70 cash payment and a $30 credit note. Smile raises commission on the pre-tax value of the $70 payment, that is, calculates the commission due on $63.
If you de-allocate a receipt from an invoice on which commission was paid, Smile recalculates the commission in the next billing run and lists any overpayments on the RCTI. The recalculation is known as clawback.
