Billable vs Non-Billable Hours: What to Charge For and Why It Matters
· 4 min read
Every freelancer and consultant works two kinds of hours: the ones clients pay for and the ones they don't. Understanding billable vs non-billable hours is about more than deciding what goes on an invoice. It shapes how you price your work, how you set expectations with clients, and whether your business is actually as profitable as it looks. This guide covers clear definitions, the gray areas, and a simple way to track both.
What counts as billable hours
Billable hours are time spent directly on client work that you've agreed to charge for. Typical examples:
- Design, writing, development, analysis, or other deliverable work
- Client meetings and calls about active projects
- Research specifically for a client's project
- Revisions within the agreed scope
- Project-specific travel, if your agreement says so
The key word is agreed. What's billable should be defined in your contract or proposal, not decided after the fact.
What counts as non-billable hours
Non-billable hours are time that keeps your business running but isn't charged to a specific client:
- Admin: email triage, bookkeeping, invoicing
- Sales and marketing: proposals, discovery calls, portfolio updates
- Learning new skills or tools
- Internal projects and your own website
- Fixing errors that were your fault
- Work you've chosen to give away as goodwill
Non-billable doesn't mean unimportant. Much of it is what brings in future billable work.
The gray areas
Some time lands in between, and handling it consistently matters more than any single rule. Here's how many freelancers approach common cases:
| Activity | Often treated as | Consider |
|---|---|---|
| Initial discovery call | Non-billable | Billable if it turns into paid strategy work |
| Quick client emails | Billable (batched) | Log a daily "communication" entry instead of tiny ones |
| Scope changes and extra revisions | Billable | Confirm in writing before doing the work |
| Onboarding a new client's tools | Depends | Spell it out in the proposal |
| Rework due to your mistake | Non-billable | Track it anyway to learn from it |
| Waiting on client feedback | Non-billable | Not work time unless you're on standby by agreement |
When in doubt, discuss it upfront. Clients rarely object to paying for work they expected; they object to surprises.
Billable vs non-billable hours: why track both
It's tempting to only track what you can bill. But tracking non-billable time too gives you data you can't get any other way.
Your real billable percentage. If you work 45 hours a week and bill 27, your utilization is 60%. That number is essential when calculating your freelance hourly rate.
Your effective hourly rate per client. Say you bill a client $100/hour for 20 hours a month, but spend another 8 non-billable hours on their endless emails and unpaid calls. Your effective rate for that client is $2,000 ÷ 28 hours ≈ $71/hour. That's useful information when renewing or repricing.
Better estimates. Knowing how much overhead each project generates helps you quote future work more accurately.
How to flag hours correctly
The simplest system is to track every hour against a client and project, then flag each entry as billable or non-billable. A few habits keep it clean:
- Decide at the time of entry. It's easier to flag an entry correctly when you log it than to remember a week later.
- Create an internal "client" for your own business. Put admin, marketing, and learning under it, all non-billable.
- Use clear descriptions. "Fixed layout bug I introduced" makes the non-billable reason obvious later.
- Review before invoicing. Scan the period for anything flagged incorrectly before you generate an invoice.

Improving your billable ratio
You'll never be 100% billable, and you shouldn't try. But you can nudge the ratio up:
- Batch admin into one block a day or week.
- Use templates for proposals and recurring emails.
- Charge for scope changes and extra revisions per your agreement.
- Consider a paid discovery or strategy session instead of long free calls.
- Automate invoicing so it takes minutes, not an afternoon.
FAQ
Should non-billable hours appear on an invoice?
Usually not. Some freelancers show non-billable work at $0 to demonstrate goodwill, but most keep invoices limited to billable time and keep non-billable hours for internal analysis.
What is a good billable utilization rate for a freelancer?
It varies a lot by field and business stage. Many solo freelancers find 50–75% realistic once sales and admin are counted. Track your own for a few months and use that as your baseline.
Is time spent on proposals billable?
Generally no, unless the client has agreed to pay for a paid scoping or planning phase.
Track both sides of your week
Knowing your billable vs non-billable hours turns a vague sense of "busy" into numbers you can act on. In ClockPaid, every time entry carries a billable flag, and only unbilled billable time goes onto invoices, so non-billable work stays in your reports without reaching the client. You can start free and see your real split within a few weeks. For more on building the habit, read how to track billable hours.
