ShareASale reports refunds differently to most other networks. Refunds are applied on the day the refund is created, not the original date of the transaction. By default Affluent shows refunds applied on the date of the transaction (not the date of the refund).
Affluent can, on an organisational level, apply a change that counts refunds on the date of the original transaction rather than how ShareASale reports them. If this change is applied the net numbers will not match ShareASale.
