How Much Does It Cost to Build a Marketplace App?
A two-sided marketplace — buyer and seller flows, listings, payments with splits, and reviews — runs €10,000–32,000 with a senior developer. Agencies charge €60,000–160,000. Marketplace complexity scales quickly; the payment split layer alone can double scope if underestimated.

Working with Dusko
I built and shipped a FlutterFlow template marketplace on the official FlutterFlow marketplace — a real two-sided platform with Stripe and Firebase. Marketplaces are complex; scoping them correctly at the start is the most valuable thing I bring.
