Billable vs Non-Billable Design Time Explained
Every hour your design team works costs money. But not every hour generates revenue. This comprehensive guide explains how to categorize billable vs non-billable design time, maximize profitability, and track the metrics that matter for creative agency success.
The Hidden Profitability Problem
Design agencies face a brutal reality: paying designers for 40 hours/week while only billing clients for 25-30 hours.
The Math:
Full-time designer salary: $75,000/year
Total comp (+ benefits, taxes): $95,000/year
Hours per year: 2,080 hours (52 weeks × 40 hours)
True hourly cost: $95,000 ÷ 2,080 = $45.67/hour
Billable hours per week: 28 hours (70% utilization)
Annual billable hours: 1,456 hours
Revenue required per hour: $95,000 ÷ 1,456 = $65.25/hour (just to break even)
To make 30% profit margin:
Required billing rate: $93.21/hour minimum
But you're probably charging: $125-150/hour
Actual profit IF you hit 70% utilization: $87,000-$123,000 per designer
The Problem: Many agencies run at 50-60% utilization, killing profitability.
Why This Happens:
- Don't track time accurately
- Don't distinguish billable vs non-billable
- Write off too much time without realizing it
- Scope creep eats billable hours
- Poor project estimates
- Inefficient processes
This article teaches you how to fix it.
Understanding Billable vs Non-Billable Time
Definitions
Billable Time: Work that directly benefits a specific client project and can be legitimately charged to that client.
Non-Billable Time: Work that benefits the agency, supports operations, or cannot be charged to clients.
The Gray Area: Some work falls in between and requires judgment. We'll cover these scenarios.
Why the Distinction Matters
For Profitability:
Scenario A: 60% Billable Utilization
Annual billable hours: 1,248 hours
Revenue @ $135/hour: $168,480
Cost: $95,000
Gross profit: $73,480 (44%)
Scenario B: 75% Billable Utilization
Annual billable hours: 1,560 hours
Revenue @ $135/hour: $210,600
Cost: $95,000
Gross profit: $115,600 (55%)
Difference: +$42,120 profit per designer
A 15 percentage point increase in utilization = 57% more profit.
For Pricing: If you don't know your true billable time, you can't price projects accurately:
❌ Project estimate based on 40 hours
Reality: 40 billable + 12 non-billable = 52 total hours
Result: Project is unprofitable
✓ Project estimate accounts for realistic utilization
Bid includes buffer for normal non-billable activities
Result: Project hits target margins
For Capacity Planning:
Can we take on a new 100-hour project?
Wrong calculation:
2 designers × 40 hours/week × 4 weeks = 320 hours available ✓
Right calculation:
2 designers × 28 billable hours/week × 4 weeks = 224 hours available
100-hour project + existing commitments = Overbooked ✗
Must account for non-billable time in capacity planning
What Counts as Billable Design Time

When to Bill for Typically Non-Billable Work
Some activities are usually non-billable but CAN be billable if:
Learning Client-Specific Tools:
❌ Generally non-billable: Learning Figma
✓ Billable: Learning client's proprietary design system
If client requires specific knowledge for their project,
that learning time can be included in project scope.
Travel Time:
❌ Non-billable: Commuting to your office
✓ Billable: Travel to client site for meetings/workshops
✓ Billable: Travel for on-site design work
Include in proposals: "Travel time billed at 50% rate"
Excessive Research:
❌ Non-billable: General industry research
✓ Billable: Deep-dive research specifically for client project
✓ Billable: If research is a defined project deliverable
Set expectations: "Up to X hours of research included"
What Counts as Non-Billable Design Time
Core Non-Billable Activities
1. Internal Team Meetings
✗ Weekly all-hands meetings
✗ Internal project planning (before client exists)
✗ Design team critiques (not client-specific)
✗ Administrative meetings
✗ Company town halls
Example: Friday design team critique
- Designers present work in progress
- Team provides feedback
- Helps quality but not billable to any specific client
- Coded as: Non-billable / Agency Operations
2. Sales and Business Development
✗ Initial sales calls with prospects
✗ Creating proposals and estimates
✗ Responding to RFPs
✗ Pitch presentations
✗ Networking events
✗ Conference attendance (unless client-sponsored)
Example: Prospect calls and proposal creation
- Discovery call: 1 hour (non-billable)
- Creating proposal: 3 hours (non-billable)
- Proposal presentation: 1 hour (non-billable)
Total: 5 non-billable hours
If you win the project, this is your customer acquisition cost.
If you lose, it's entirely written off.
3. Administrative Tasks
✗ Timesheet entry
✗ Expense reports
✗ Reading company emails
✗ Managing personal calendar
✗ Software updates
✗ General housekeeping
Example: Weekly administrative overhead
- Timesheet entry: 0.5 hours
- Email management: 1 hour
- Scheduling: 0.5 hours
Total: 2 non-billable hours per week (5% of time)
Necessary but not chargeable to clients
4. Training and Professional Development
✗ Learning new design tools
✗ Taking online courses
✗ Watching tutorials
✗ Reading design articles
✗ Skill development
✗ Team training sessions
Example: Designer learns new Figma features
- Tutorial watching: 2 hours (non-billable)
- Practice exercises: 2 hours (non-billable)
Benefits future client work but not specific to any project
5. Internal Projects and R&D
✗ Agency website design
✗ Internal tools development
✗ Marketing material creation
✗ Portfolio case study development
✗ Experimental design projects
✗ Agency branding updates
Example: Updating agency website
- All design and development time: Non-billable
- This is marketing investment, not client work
6. Rework Due to Errors
✗ Fixing mistakes you made
✗ Redoing work because you misunderstood
✗ Correcting technical errors
✗ Implementing missed requirements
Example: Designer uses wrong brand colors
- Original design: 3 hours (billable)
- Fixing color mistakes: 1.5 hours (non-billable)
Eat the cost of your own errors - don't bill clients
7. Excessive Revisions Beyond Scope
✗ Revision round 4+ (if contract includes only 2)
✗ Major direction changes after approval
✗ Client indecision leading to constant changes
✗ "While we're at it" scope creep
Example: Logo design includes 2 revision rounds
- Revisions 1-2: Billable (in scope)
- Revisions 3+: Non-billable (or renegotiate)
Options:
- Write off (non-billable)
- Stop work and renegotiate for additional rounds
- Include in scope next time with higher pricing
8. Downtime Between Projects
✗ Waiting for client feedback
✗ Waiting for next project to start
✗ Time between client assignments
✗ Bench time (no active projects)
Example: Designer completes Project A on Thursday
- Next project starts Monday
- Friday time: Non-billable downtime
Goal: Minimize through better project scheduling
Strategic Non-Billable Time
Some non-billable time is investment, not waste:
Portfolio Development:
Creating compelling case studies:
- Time spent: Non-billable
- Return: Wins more clients and higher rates
- Worth it: Yes
Budget: 5-10 hours per major project
Treat as marketing expense
Thought Leadership:
Writing articles, speaking, creating content:
- Time spent: Non-billable
- Return: Brand awareness, inbound leads
- Worth it: Yes
Budget: 2-4 hours per week for senior designers
Generates inbound business development
Process Improvement:
Building templates, improving workflows:
- Time spent: Non-billable today
- Return: Faster billable work tomorrow
- Worth it: Yes
Budget: 1-2 hours per week
Compounds efficiency over time
The Gray Area: When It's Not Clear
Scenario-Based Guidance
Scenario 1: Research and Inspiration
Question: Is looking at design inspiration billable?
It depends:
❌ Non-billable:
- General browsing of design sites
- Building personal inspiration library
- Staying current with design trends
✓ Billable:
- Researching specific client's industry
- Finding inspiration for active project
- Competitive analysis for client
- Limited to reasonable scope (2-3 hours max)
Best practice: Set research time limit in proposal
"Up to 3 hours of competitive research included"
Scenario 2: Concept Development
Question: Is exploring multiple concepts billable?
It depends:
❌ Non-billable:
- Creating 8 concepts when client only asked for 3
- Over-delivering because you're enjoying the work
- Experimenting beyond project requirements
✓ Billable:
- Creating agreed-upon number of concepts (e.g., 3 directions)
- Exploration explicitly scoped in contract
- Client-requested concept variations
Best practice: Define in proposal
"3 initial design directions, client selects 1 to refine"
Scenario 3: Internal Review Before Client Delivery
Question: Is internal QA and review billable?
Generally no, but...
❌ Non-billable:
- Internal creative director review
- Team critique before client presentation
- QA and error-checking
Why: These are quality control measures for YOUR benefit
Client shouldn't pay for you to check your own work
Exception: ✓ Billable if explicitly in scope
"Creative director oversight included: 10% of design time"
Add to project price, but don't line-item it
Scenario 4: Email Communication
Question: Is email time billable?
Use this framework:
✓ Billable email:
- Responding to client design questions
- Providing project updates
- Clarifying requirements
- Design decision explanations
Limit: Round to nearest 15 minutes, cap at reasonable amount
❌ Non-billable email:
- Scheduling/logistics
- Administrative coordination
- General check-ins
- "Thanks" or "Got it" responses
Too small to track
Scenario 5: Presentations and Prep
Question: Is presentation preparation billable?
Split it:
✓ Billable:
- Creating presentation deck with designs
- Organizing client-facing materials
- Preparing to explain design decisions
❌ Non-billable:
- Excessive rehearsal time
- Internal presentation reviews
- Creating overly elaborate presentations
Rule of thumb: Bill 50% of prep time for major presentations
1 hour meeting → 0.5 hours prep (billable)
Scenario 6: Project Management Time
Question: Is project management billable?
Yes, but cap it:
✓ Billable (within reason):
- Creating project timelines
- Status reporting to client
- Coordinating feedback
- Managing deliverables
Typical: 10-15% of total project hours
❌ Over-billing PM:
Don't charge 20 hours of PM for 40 hours of design work
Client will see this as padding
Include PM time in your hourly rate or flat project pricing
Scenario 7: Revisions vs. New Work
Question: Client asks for changes - revision or new work?
Framework:
✓ Revision (billable within rounds):
- Adjusting existing design elements
- Changing colors, fonts, layouts
- Refining approved direction
✓ New Work (billable as change order):
- Complete direction change
- Adding new pages/deliverables
- Expanding scope beyond original
Example:
Client: "Can we try a completely different approach?"
Response: "That would be a new concept beyond our revision rounds.
I can provide a quote for exploring that direction if you'd like."
Tracking Billable vs Non-Billable Time
Time Tracking Best Practices
Using Corcava's Time Tracking:
Step 1: Create Project Categories
Client Projects (Billable):
- Client A - Website Redesign
- Client B - Brand Identity
- Client C - Marketing Materials
Internal Projects (Non-Billable):
- Agency Operations
- Business Development
- Professional Development
- Internal Projects
- PTO/Vacation
Step 2: Track All Time
Designer's day:
9:00-9:30 AM → Email and admin (Non-billable: Agency Operations)
9:30-12:00 PM → Client A website design (Billable: Client A)
12:00-1:00 PM → Lunch (Not tracked)
1:00-2:00 PM → Internal team meeting (Non-billable: Agency Operations)
2:00-5:00 PM → Client B brand concepts (Billable: Client B)
5:00-5:30 PM → Proposal for prospect (Non-billable: Business Development)
Total tracked: 7.5 hours
Billable: 5.5 hours (73% utilization)
Non-billable: 2 hours (27%)
Step 3: Add Task-Level Detail
Time entry example:
Project: Client A - Website Redesign (Billable)
Task: Homepage Design
Description: "Created hero section with 3 layout variations"
Time: 2.5 hours
Billable: Yes
Date: November 10, 2025
Step 4: Review and Approve
Weekly time review process:
1. Designer submits timesheet
2. Project manager reviews billable hours
3. Flag questionable entries:
- "Is this really billable?"
- "This seems high for that task"
- "Was this in scope?"
4. Adjust as needed before invoicing
5. Discuss patterns with team
Time Entry Guidelines for Designers
Best Practices:
1. Track in Real-Time
❌ Don't: Try to remember at end of week
✓ Do: Track as you work or at end of each day
Result: 20-30% more accurate time data
2. Be Honest
❌ Don't: Round everything up or pad time
✓ Do: Record actual time worked
Result: Accurate project profitability data
3. Use Descriptive Task Names
❌ Bad: "Design work - 3 hours"
✓ Good: "Homepage hero section - 3 layout concepts - 3 hours"
Result: Client understands invoice, you can analyze time
4. Flag Uncertainty
If you're not sure whether time is billable:
- Track it
- Add note: "Verify if billable"
- Let project manager decide
Result: Consistent policy application
5. Separate Billable from Non-Billable
Working on Client A project but spend 30 min troubleshooting Figma:
Track as:
- 3 hours → Client A (billable)
- 0.5 hours → Agency Operations (non-billable: software issues)
Don't bill client for your software problems

Calculating Utilization Rates
The Formula
Billable Utilization Rate:
(Billable Hours ÷ Total Available Hours) × 100 = Utilization %
Example:
Billable Hours: 28 hours
Available Hours: 40 hours
Utilization: (28 ÷ 40) × 100 = 70%
What to Include in "Available Hours":
✓ Include:
- Regular work hours (typically 40/week)
- Overtime if expected to be billable
✗ Exclude:
- PTO/vacation days
- Sick days
- Holidays
- Unpaid leave
Adjusted calculation:
If designer takes 1 day off (8 hours):
Available hours: 32 (not 40)
Billable hours: 24
Utilization: (24 ÷ 32) × 100 = 75%
Target Utilization Rates
Industry Benchmarks:
EXCELLENT: 75-80% billable
- High project load
- Efficient workflows
- Minimal non-billable time
GOOD: 70-75% billable
- Healthy project pipeline
- Sustainable workload
- Standard non-billable activities
ACCEPTABLE: 65-70% billable
- Some downtime between projects
- More internal responsibilities
- Junior designers (more training time)
CONCERNING: 60-65% billable
- Insufficient project pipeline
- Too much non-billable work
- Process inefficiencies
PROBLEM: < 60% billable
- Not enough client work
- Excessive non-billable activities
- Agency is losing money on this person
By Role:
Junior Designer: 60-70%
- More learning and training time
- Less efficient than senior staff
- May support non-billable work
Mid-Level Designer: 70-75%
- Mostly client work
- Some mentoring junior staff
- Balanced workload
Senior Designer: 75-80%
- Primarily client-facing
- Efficient workflows
- Minimal non-billable drain
Creative Director: 50-60%
- Lots of oversight (non-billable)
- Business development
- Team management
- Less hands-on design
Account Manager: 65-75%
- Client communication (billable)
- Proposal writing (non-billable)
- Project coordination
What to Do About Low Utilization
If Team Member Under 65%:
Step 1: Diagnose the Problem
Run report: Where is non-billable time going?
Scenario A: Lots of "Downtime/No Project"
→ Problem: Not enough work
→ Solution: Sales/pipeline issue
Scenario B: Lots of "Internal Meetings"
→ Problem: Meeting overload
→ Solution: Reduce meeting time
Scenario C: Lots of "Rework/Revisions"
→ Problem: Quality or scope issues
→ Solution: Improve process or tighten scope
Scenario D: Lots of "Administrative"
→ Problem: Inefficient processes
→ Solution: Automate or delegate
Step 2: Take Corrective Action
For Pipeline Issues:
- Increase business development
- Adjust pricing to win more work
- Consider temp/contract work to fill gaps
For Process Issues:
- Identify and eliminate time-wasters
- Automate repetitive tasks
- Streamline approval processes
For Skill Issues:
- Provide training to increase speed
- Better project assignments
- Consider role adjustment
Step 3: Set Improvement Goals
Current: 62% utilization
30-day goal: 68% utilization
60-day goal: 72% utilization
90-day goal: 75% utilization
Weekly check-ins to track progress
Maximizing Billable Hours
Reducing Non-Billable Time
Strategy 1: Automate Administrative Tasks
Manual timesheet entry: 2 hours/week non-billable
Switch to [automatic time tracking](https://app.corcava.com/register): 0.25 hours/week
Time saved: 1.75 hours/week = 91 hours/year
Converted to billable at $135/hour = $12,285 extra revenue/year
Strategy 2: Reduce Internal Meetings
Current: 6 hours of meetings/week
Goal: 3 hours of meetings/week (50% reduction)
Time saved: 3 hours/week = 156 hours/year
Converted to billable at $135/hour = $21,060 extra revenue/year
How:
- Make meetings shorter (30 min instead of 60 min)
- Make meetings less frequent (biweekly instead of weekly)
- Invite fewer people (only who needs to be there)
- Cancel meetings that can be emails
Strategy 3: Improve Sales Efficiency
Current: 10 hours to create proposal, 40% win rate
Goal: 5 hours to create proposal (templates), 50% win rate
Time saved per proposal: 5 hours
Extra wins: +25% more projects closed
Result: Less time per proposal + more wins = better ROI on BD time
Strategy 4: Better Project Scoping
Problem: Vague scope leads to excessive free revisions
Solution: Detailed scope with limited revisions
Before:
- "Design homepage" (vague)
- Client requests 5 revision rounds
- 20 hours non-billable rework
After:
- "Design homepage with 2 revision rounds included"
- Round 3+ requires change order
- 5 hours non-billable rework (75% reduction)
Strategy 5: Template and Systematize
Create reusable templates for:
- Common design patterns
- Project proposals
- Client onboarding
- Design specifications
- Delivery documentation
Time saved: 2-4 hours per project
Over 20 projects/year = 40-80 hours saved
= $5,400-$10,800 extra billable revenue
Increasing Billable Opportunities
Strategy 1: Proactive Upsells
During project, identify additional needs:
"While designing your website, I noticed you need:
- Social media template suite
- Email newsletter templates
- Display ad templates
Would you like a proposal for these?"
Result: More billable work from existing happy clients
Strategy 2: Retainer Agreements
Convert project clients to monthly retainers:
One-off projects:
- Feast or famine revenue
- Lots of non-billable sales time
- High client acquisition cost
Retainers:
- Predictable billable hours
- Less non-billable sales time
- Higher lifetime value
See our [complete retainer management guide](/blog/design-retainer-management)
Strategy 3: Clear Hourly Tracking
Track billable time in visible increments:
15-minute minimum:
Small tasks add up:
- 5 min client email → Round to 15 min (billable 0.25 hr)
- 10 min file adjustment → Round to 15 min (billable 0.25 hr)
- 20 min status call → Round to 30 min (billable 0.5 hr)
Over a week, this captures 2-3 hours more billable time
that would otherwise be written off as "too small to track"
Strategy 4: Reduce Scope Creep
Client: "While we're at it, can you also..."
❌ Wrong response: "Sure!" (free work)
✓ Right response: "Absolutely! That would be a change order.
Let me send you a quick estimate."
Protect billable hours by:
- Defining scope clearly upfront
- Using change order process for additions
- Training team to recognize scope creep
- Educating clients on what's included
Agency-Wide Utilization Management
Setting Targets by Quarter
Example Agency (5 designers):
Q1 Target: 68% average utilization
- Project pipeline building
- Post-holiday slowdown

Handling Common Scenarios
Scenario: Client Questions Your Invoice
Client: "Why are you billing 45 hours when the project estimate was 40 hours?"
Wrong Response: "That's just how long it took."
Right Response: "Good question! Let me break it down:
- Original scope: Homepage design with 2 revision rounds (40 hours)
- Actual work:
- Initial design: 18 hours (as estimated)
- Revision round 1: 10 hours (as estimated)
- Revision round 2: 12 hours (as estimated)
- Additional revision round 3: 5 hours (not in original scope)
You requested a third revision round which added 5 hours. Would you like me to waive that for this project, or shall we adjust the scope on future projects to include 3 rounds?"
Key: Transparency + clear scope documentation
Scenario: Designer Consistently Over-Billing
Problem: Designer bills 38-40 hours/week when agency average is 28 hours.
Investigation Questions:
- Are they actually working more? (check deliverables)
- Are they padding time? (compare to task complexity)
- Are they less efficient? (compare to other designers)
- Are projects under-scoped? (check against estimates)
Possible Actions:
If over-working: Redistribute load, watch for burnout
If padding: Coaching on honest time tracking
If inefficient: Training or performance management
If under-scoped: Adjust future estimates
Scenario: Too Much Non-Billable Time
Problem: Agency running at 55% utilization (target: 70%).
Root Cause Analysis:
Step 1: Where is non-billable time going?
Run report by category:
Non-billable breakdown:
- Downtime/no projects: 18% (PROBLEM: not enough work)
- Internal meetings: 12% (normal)
- Administrative: 8% (high, target 5%)
- Business development: 7% (normal)
Step 2: Address biggest problem first
Issue: Not enough client work (18% downtime)
Actions:
- Increase business development efforts
- Lower prices temporarily to win more work
- Consider taking on contract/freelance projects to fill gaps
- Market more aggressively
Step 3: Address second problem
Issue: Too much admin time (8%)

Financial Impact of Utilization
The Profitability Math
Agency with 5 Designers:
SCENARIO A: 60% Utilization (Poor)
─────────────────────────────────────
Annual billable hours: 6,240 (5 × 2,080 × 60%)
Billing rate: $135/hour
Revenue: $842,400
Costs:
- Designer salaries: $475,000
- Overhead (50%): $237,500
Total costs: $712,500
Profit: $129,900 (15% margin) ⚠️
SCENARIO B: 70% Utilization (Good)
─────────────────────────────────────
Annual billable hours: 7,280 (5 × 2,080 × 70%)
Billing rate: $135/hour
Revenue: $982,800
Costs: $712,500 (same)
Profit: $270,300 (28% margin) ✓
SCENARIO C: 75% Utilization (Excellent)
─────────────────────────────────────
Annual billable hours: 7,800 (5 × 2,080 × 75%)
Billing rate: $135/hour
Revenue: $1,053,000
Costs: $712,500 (same)
Profit: $340,500 (32% margin) ✓✓
DIFFERENCE B → C:
+$70,200 profit (26% increase)
Just from 5 percentage points of utilization improvement
The Takeaway: Small improvements in utilization = massive profit impact.
Break-Even Utilization
What utilization do you NEED to break even?
Formula:
Break-even utilization = Total Costs ÷ (Billing Rate × Available Hours)
Example:
Total costs: $712,500
Billing rate: $135/hour
Available hours: 10,400 (5 designers × 2,080 hours)
Break-even = $712,500 ÷ ($135 × 10,400)
Break-even = $712,500 ÷ $1,404,000
Break-even = 50.7% utilization
Below 51% utilization = losing money
Above 51% utilization = profitable
Target 70%+ for healthy margins
