Ordentic charges a commission per order. There are no setup fees or fixed monthly costs for selling on Ordentic.
Your current commission rate is shown in Preferences under Commission & legal. The commission terms are also on Commission, Fees, and Payout Terms.
Commission is calculated on line subtotals excluding shipping and excluding VAT. Shipping is not included in commission. Your rate can be specific to your account, so use Preferences for the live rate rather than a fixed percentage in this article.
