If you are using Lab Fulfillment via the Pixieset Store, the Pixieset Application Fee you see in the dashboard is the Cost of Goods Sold that we forward to the printer (WHCC, ProDPI, Miller's, Mpix, or Loxley Colour).
If you add up the cost of the ordered prints and the shipping charges paid by your client this will equal the amount of the Pixieset Application Fee.
You can view a detailed breakdown of this amount in your Store dashboard at any time. To do this, go to the Store Dashboard, click on Orders, and then click View next to the Order you wish to review.
You can then click on the Cost of Goods total at the bottom of the Order detail page, in order to review the breakdown of all Cost of Goods charges. You'll be able to confirm that you have not been charged a Commission Fee since you are on the upgraded Account; the only Cost is the Lab's actual printing and shipping Costs.
