I've read a lot of interesting comments on here, but what is everyone's stand point on support. Do you offer free support? Do you charge? Do your clients ask for it? Obviously a change request is chargeable, but what about a bug? I used to do freelance work face to face, I made a nice chunk of money from it - but in the end the support I had to give was exhausting. Most of it was neither a bug to be fixed or a request requiring a change, often in fact the support query was completely unrelated to my freelance work. This is one problem with freelancing in general. At the start it is easy, fun, creative and you are printing money. However, the more clients you have, the more work you do and the more money you make, is counter balanced by the increase in support duties. I decided to join a software consultancy instead, doing roughly the same role as when I was freelancing. The only difference is, now I get paid a salary (which is a lot less) and our support team handle the support of clients. (Something which many clients actually are happy to pay a premium / service fee for). This said, I see how much money things cost clients compared to my salary (for my work) and get the temptation to just go freelance again. So HN freelancers, what is your standpoint on ongoing support?
