Charging by the hour tells your clients that you mean business. Time is money and you’re keeping the meter running with every meeting and phone conference. No matter how many times I set limits on design iterations or halted work when clients didn’t respond in a timely manner, I learned (the hard way) that flat-fee bids gave clients license to extend projects well beyond reasonable deadlines. Yes, I had client work, but I wasn’t making any money on my projects and found it harder to line up future work with project milestones that slipped often.
I took a look at how I managed my projects. Communication with clients was always good and I provided changes to the work in a timely basis. I couldn’t figure out why so many of my projects were taking forever to complete. Cue Miriam Aarons.
