Is Time Based Billing on the roadmap? We are keen to sell access packages based on time, for example, you can buy a month, a week a day etc?
Likely something Sonar will be able to work with you after v2 is released to the public.
We would love to see prepaid hour blocks supported, too. For example, a customer buys a block of 20 hours at a discounted rate and then we deduct from those hours as we do work for them.
