Flippa always recommends completing thorough due diligence before bidding on an auction.
While Flippa doesn't specifically require it, one of the best practices used by our top buyers is having a videocall and/or screen sharing with the other user.
Please note: Flippa users are not permitted to transfer email addresses or third-party account details publicly on listings.
You can also share screens to get a live walkthrough of how the site or app works, look at live financial and user traffic details and get a better idea of a user's veracity among other things. As with most things in life, your gut instinct is usually correct.
Three of the top technologies for video calls and screen sharing are Apple's FaceTime, Google's Hangouts, and Microsoft's Skype.
While Flippa can't offer technical support for these technologies, here are some quick links to help you get started:
