I presume you mean investing your own funds through the online platform mentioned whom in turn provide you with the opportunities to invest in certain trade receivables.
I've done a few factoring transactions (not through this site) but direct with clients and my only advice would be, you are only as safe as the receivables financial health, and as this is somewhat an unknown, carries inherent risk.
I always prefer longer term relationships whereby you can setup say a fixed and floating charge over the company or some other realisable asset of comfort, and have a good chat with all parties involved and allow yourself time to conduct thorough due diligence.
That aside, it can be a good return, within a short space of time.
From memory I charged around 7% for the first 30 days then dropped to 3% for each 30 days thereafter, something like that.
I know nothing of the site link company, or how good or bad it is, maybe speak with a large factoring group first to get their take on it and the market generally, and expected returns.
