There are any competitors in sight?
the main competitor is just the old accounting system way of doing thins
Nope, I know that some others companies are thinking about triple entry accounting via the blockchain.
One example is Fizcal

Yeah, Fizcal seems interesting as well. I've not decided yet which one I'm going to invest. Fizcal says that Ethereum won't be scalable enough for their need, but this project is going to use Ethereum. Would love to know what are PayPie's developers thinking about this? I know blockchain will revolutionalize accounting and if most companies start putting their data to Ethereum chain, this might be a lot of traffic.
However, this project looks a bit more professional to me.
Like I said before in the ANN, but I don't think I had an answer, I think that the main argument of Paypie is the Credit Risk Algorithm to distinguish themselves from competitor like Fizcal. They really enhance the fact that with the blockchain they'll obtain the most accurate one possible.
And if we're talking about this, I don't know any competitor in the credit risk field using blockchain technology.
