Good idea! Doing the bit for the community. UI could do with a full overhaul if I'm honest. If you have a quick search across Dribbble, I'm sure there's a ton of epic designs that you could use to improve this.
Is there any kind of verification process a person has to go through to post a bill? What's to stop someone simply creating a random bill for $100 and faking a story? Maybe need some ID verification (I'm sure there's third party plugins/services that can do this). I think possibly every post should be approved by an admin before it goes live, for an added layer of security/to filter trolls.
Honestly, what's stopping the developer from just pocketing it themselves?
Potentially setting up a direct payment to the person via their payment choice? For example enforce a paypal recipient as the bill creator?
So, what we decided to do to keep everyone honest throughout the process is produce receipts for payments and give everyone access to them if that makes sense.
