Good questions
Marketplace & Platform apps, answered.
Can the marketplace take a commission on each sale?
Yes. We build split payments so your platform takes its commission and sellers are paid out automatically.
Do you build the web platform as well as the app?
Yes. Our App + Platform package includes a web platform alongside your iPhone and Android apps, such as seller dashboards and an admin system.
How much does a marketplace cost?
Appro prices start from £2,495. Most marketplaces need our App + Platform package, from £8,495, scoped on a free call so you get a fixed price before we start.
Can we start small and grow?
Yes. Many founders launch a focused first version and add features as the marketplace grows.
Who owns the platform?
You do. You own the apps, the platform and the code.
