I thought I was billing about 70% of my working hours.
The real number was 41%.
I ran a simple experiment: I tracked every working hour for 60 days. Not just billable work. Everything. Client calls, proposals, admin, marketing, chasing invoices, fixing scope creep I should have charged for, social media, reading newsletters that somehow became two hours.
Here is what I found.
Where the hours actually went
- Billable client work: 41%
- Proposals and sales calls (mostly unpaid): 14%
- Admin and invoicing: 11%
- Context switching and recovery time: 9%
- Fixing things I should have charged for: 8%
- Marketing: 7%
- Everything else: 10%
I was working 45-50 hours a week and billing about 18-20 of them.
The things that surprised me
Context switching has a real cost. I knew this in theory. But seeing it as a block of time in my own data was different. Every time I jumped between a client project and a proposal and back again, I was losing 15-20 minutes of productive focus. Over a week it adds up to almost a full day.
"Fixing things I should have charged for" was the most painful category. These were bugs introduced by client-requested changes, scope creep I was too soft to push back on, and revisions beyond what the contract allowed. I was essentially giving away eight percent of my working time for free.
Proposals were eating more than I realized. I was writing detailed proposals for projects I won maybe 30% of the time. That math means roughly 70% of my proposal time was unpaid work to help clients evaluate their options.
What I changed
I introduced a paid discovery phase for projects above a certain value. Clients who are serious about working with you will pay for proper scoping. Clients who want free consulting will not.
I stopped writing detailed proposals for vague briefs. Now I require a 30-minute paid discovery call before I write anything detailed. This filters out time-wasters fast.
I blocked two focused work sessions per day and stopped checking messages during them. This alone recovered about an hour of productive time each day.
I got stricter about change orders. Not aggressive. Just clear.
60 days later
Billable percentage went from 41% to 58%. Same working hours. Different boundaries and systems.
The experiment cost me nothing except the discomfort of seeing the actual numbers.
