One of the biggest lessons I've learned as a VC in the past few years is that pricing really has to be aligned with and proportional to the value your product provides. If someone gets $100 of value per seat and you charge $15/seat, that's great. If you charge $15/seat for a product that creates value per gigabyte, people start gaming the system. E.g. they'll buy one seat for their company and ask that person to be the proxy user for your product. Or if you charge $10/GB and people get $20/GB of value of the first few gigabytes and then $5/GB of value after that, you're going to run into problems.
So figure out how users perceive and quantify your value to themselves, and then try to come up with a simple pricing scheme that captures 10-25% of that value. That way every time someone pays you $1, they get $4-$10 of value, and that's a no brainer purchase.
Getting pricing right has a huge ROI across the board. Good pricing improves margins, reduces sales friction, and creates happier customers.
