Professional sellers in a Marketplace
At the beginning of the process, I have benchmarked marketplaces and e-commerce solutions for inspiration.
To better understand user problems I created a set of personas (buyer + professional seller) based on available research and interviews conducted in the field.
Users can distinguish between professional and private ads. If in need for more details user can access a shop page to see shop information and other products offered by this seller.
Professional sellers can access a dashboard that shows the sales overall statistics over time as well as detailed information about performance of each posting separately.
