I'll probably get buried but, here's what I'm going to suggest. Don't deviate from the price too much. I'll tell you why. You're competing with pancakeapp, buggenie, bugify, redmine, bugkick, mantis, Zoho (on some level) and many more, including some of the cheaper hosted basecamp clones. And I'm already considering buying yours. Your pricing is great. And I appreciate what you're doing.
I wouldn't go more than $69 or $79 if you raise your prices at all. If you have future build plans you can always charge for the next version upgrade or specific enhancements. If you want this to be the product you work on and support, try to charge what you can to sustain yourself and grow, but you're going to turn off a bunch of freelancers at some $295 price point that people are suggesting on HN. Somebody said, "for businesses of any size the difference between $250 and $45 is negligible." Um no, These same people (thousands of comments worth) are royally pissed about the Adobe Cloud pricing and are looking for alternatives.
I wouldn't even consider it at $295 price and many others wouldn't either. Why? Because I can get a proven system for many months or permanently at that rate. And for the FOSS ones, I might even become a contributor or leverage the community for enhancements or plugins in those cases.
HN is full of people trying to charge more and a ton of them are going to fail or become irrelevant. Basically your product is for freelancers, not enterprise. That's a fact, luck of the draw, however you want to look at it. Enterprise might trickle in after enough freelancers are rocking your system. Enterprise use Mantis, and that's free. Why should they be turned off by a low price. You might even find small businesses you didn't think of using you product that will be more attracted to your price. There are other things you can do, like try to get bundled with something else, or offer installation service at a rate.
Sell it on your own if you can using Stripe or some other managed provider that isn't taking so much of a cut. Or don't sell it exclusively on codecanyon. you should be making the majority of the money, a lot more than half.
