Define the business model that suits your multi-vendor business app

Commission model

This is the most viable business model among online marketplace platforms available on the internet. Here, the platform allows you to charge a commission on every transaction made on the marketplace; simple, when a buyer pays a seller for a particular product, the marketplace charges a certain amount as a fee. 

Marketplaces like Airbnb, Etsy, and Uber are using a commission business model for their business. 

Membership model

The membership model is another successful business model where the users of the marketplace platform are charged a fee to get access to the platform. This business model helps sellers find the value shoppers to save money on the transactions or find unique experiences. 

Listing fees

Creating a design and app screens

It is enough to render and design a few to explain and elaborate screen proceedings to go with – the goals, target audience, and functionality. All these are important to create a design concept. 

By default, every designer who closely works on the project should offer several styles to choose from. Once the design concept has been approved, the rest of the screens are rendered about it. 


Every marketplace-like complex app should start with the MVP – Minimum Viable Product. An MVP is a basic version of the application with only the core features to justify the need of the early customers and get feedback for future product development.
