A basic feature that’s often overlooked. Let your loyal customers advertise for you. Make it easy for active users to share listings with their social networks.

How to create your own online marketplace

Depending on the type of marketplace you want, you have a few options. You could code it yourself... if you have the technical knowledge. But be warned, an app like eBay is a big undertaking – it’s around 50 million lines of code.

Alternatively, you could hire a development team that does standalone marketplace software. It’ll likely run well. The issue is it’s expensive and takes a long time. All the design, coding and testing will be billed at their hourly rate. It adds up fast!
