Item fees are a great way to boost your revenue to help cover your costs. Item fees are applied to an item after setting it's price. For example, if you set your item fee to $1.00 across the board (simple fee), if you set the price of something to $4.99 your sticker price will be $5.99. Item fees can also be setup in price tiers (complex fees) with the fee depending on the price you set for an item.
Item fees are not payed by consignors and they are not shared with consignors, buyer's pay the fee when the item sells. When Rose reads your sales in from Square, the item fee is removed and the leftover is then split with your consignors according to the splits you have setup for them.
