A fee model is a model via which you can automatically charge advertisers for the traffic and/or the conversions the partners in your platform are generating. How the advertiser will be billed (via invoice or deposit), depends on the billing mode you have selected for your advertiser. Please note that creating a fee model is only necessary when you have selected ‘postpayment direct’, ‘postpayment standard’, ‘prepayment’ or ‘self billing’ as a billing option. If you have selected ‘no billing’, you will find that it is not possible to create a fee model.

You can both deactivate and delete a fee model by changing its status. Make sure you are on the page with the overview of the fee models of the relevant advertiser and click on the icon next to model you want to change. Again, the main settings will be displayed, along with the status of the fee model. Just put it on ‘deactived’ ‘deactivated’ of ‘deleted’ and hit ‘save’ at the bottom of the panel.
