You set the markup. The retail is just math.

How we apply it on a shop

Retail = (wholesale + extras) × (1 + markup% / 100). If wholesale is $12.50, extras $1.75, and markup 40%, landed cost is $14.25 and retail is $19.95. Round how you like on the live site; this widget shows two decimals.

Bizzit Pro is $12/month for the hosted business and a custom domain, it is not a cut of these product prices. Visitor checkout, when you connect it, uses your payment account. Related: catalog fill, shipping calculator, pricing.
