Hourly billing feels fair to everyone and quietly limits you. It ties income to hours available, punishes you for getting faster, and turns every conversation about value into a conversation about timesheets.
The three problems
- A hard ceiling: there are only so many billable hours, and the good ones are finite.
- Perverse incentive: the better you get, the fewer hours a job takes, the less you earn.
- Wrong conversation: the client scrutinizes your speed instead of your outcome.
There is also a psychological cost. Hourly makes clients hesitate before calling you, which is exactly backwards — you want to hear about problems early, not after they have grown.
When hourly is still correct
- Genuinely undefined work, where scope cannot be estimated honestly.
- Ongoing advisory where the value is availability rather than deliverables.
- Early in a new service line, while you learn how long things actually take.
Even then, track your effective hourly rate on fixed-price work — total fee divided by hours actually spent. That number, not your quoted rate, is what you actually earn, and it is the number to improve.
Try it
Take your last five projects and calculate the effective hourly rate for each. The spread will surprise you, and the best one usually points at what you should be selling more of.
