What are some suggested methods to bill clients for ongoing active software you've written for them?
I mean when they have an issue, do you tell them to call you, or email you and do you take care of the issue?
What if they have a list of things that are not functioning correctly (for various reasons beyond your control)
and you could fix the issues quickly, do you charge them?
Has any developer been setup on a retainer or consultant basis to handle issues? If so what are reasonable
rates to charge clients, monthly, weekly etc.?
How do you handle client charges for ongoing maintenance of the project?
How would you advise the client to handle this?
Thanks so much
