> If you have a good client who regularly needs small tweaks, charge a monthly retainer instead of an hourly rate.

I like this idea, how does that work? I have worked with clients who would (after completion of project)contact me few times a month for minor tweaks which require less than 30-40mins of work and I am unable to bill them logically for it until it accumulates to actually charge them in total.
