The Payability fee is based on gross sales.
Gross sales equal the amount the buyer has to pay for an order. Any negative amounts (fees, charges, refunds, etc) imposed by your marketplace will be deducted from your available balance as they come in. These are listed under Selling Platform Charges.
In the example below, you can see that we purchased $1,005.94 of gross sales which were added to the available balance. The 2% fee for this purchase was $20.12 which was then deducted from the available balance.
We understand that you may need a full fee report or a year-end summary for tax purposes. You can find this in your Reconciliation View > ‘Export Detailed View.’ The fee is displayed in column G of the report.
