Marketplace for the sale of physical (or virtual) products or services between two parties (BtoB, BtoC, CtoC), including a delivery management module. The platform can combine several business models, such as commission on each transaction or subscription.
Platform for renting physical goods or booking services between users (BtoB, BtoC, CtoC). This solution includes an advanced booking module for availability management, with the option of adopting a business model based on commission, subscription or a combination of the two.
A platform designed to facilitate contact between requesters and service providers. It lets users send requests, receive quotes or offers, and then, once a proposal has been selected, complete the transaction directly through the platform. A matching algorithm can be implemented to select the most suitable providers.
Classified ads site with no direct transaction management between users. Transactions take place outside the platform, but users can contact each other through the site. Monetisation options are available via subscriptions or paid promotion for advertisers.
A project that falls outside the standard scope — a bespoke matching algorithm, an ERP integration, a particular payment connector? We price it after a scoping meeting.
