Internal Controls
The Guardrails of Your Business
May 14, 2026
Welcome to part thirteen of our series, 40 Accounting Terms Every Business Owner Should Know. For service-based entrepreneurs—like the creative agencies, consultants, and specialized trade professionals we partner with—time isn’t just money; it is your primary inventory.
Unlike a retail store that can count the shirts on a rack, your "inventory" is the finite number of hours you and your team have each week. If you don't distinguish between Billable and Non-Billable hours, you might find yourself working 60 hours a week but only getting paid for 20. Let’s look at how to tell the difference and why this distinction is the key to your professional clarity.

Billable Hours: The Revenue Drivers
Billable Hours are the golden hours. These are the increments of time spent working directly on client projects that can be charged to the client. This is the time that directly increases your Revenue.
Examples include:
The Punchline: If the work is moving a specific client’s project toward the finish line, it’s billable. Every minute in this category should be captured with surgical precision.
Examples include:
- Deep Work: Writing code, designing graphics, or drafting strategy reports.
- Communication: Client meetings, consultations, and status update calls.
- Research: Project-specific research or competitive analysis for a client.
- Iterating: Revisions and edits requested by the client within the scope of work.
The Punchline: If the work is moving a specific client’s project toward the finish line, it’s billable. Every minute in this category should be captured with surgical precision.
Non-Billable Hours: The "Business of the Business"
Non-Billable Hours are the hours you spend on tasks that are necessary to keep the doors open but cannot be charged to a specific client. In accounting terms, these hours fall under your Operating Expenses (OPEX).
Examples include:
The Punchline: These hours are an investment in your business’s infrastructure, but they don’t produce an immediate paycheck. If these hours grow too large, they "starve" your billable capacity.
Examples include:
- Marketing & Sales: Networking, posting to social media, or pitching to new leads.
- Administrative Tasks: Organizing your digital files, checking general emails, or office maintenance.
- Growth: Professional development, taking a course, or attending a conference.
- Operations: Managing your own finances (unless you hire True North Bookkeeping, LLC to do it for you!).
The Punchline: These hours are an investment in your business’s infrastructure, but they don’t produce an immediate paycheck. If these hours grow too large, they "starve" your billable capacity.
The "Utilization Rate": Your Efficiency Scorecard
How do you know if you're actually running a business or just a very busy hobby? We look at your Utilization Rate:
(Billable Hours/Total Hours Worked) x 100 = Utilization Rate
(Billable Hours/Total Hours Worked) x 100 = Utilization Rate
- The "Low" Trap (Under 40%): You are spending too much time on "admin" or marketing that isn't converting. You might feel exhausted, but your P&L won't reflect the effort.
- The "Burnout" Zone (Over 90%): You are likely neglecting the long-term growth of your business. You have no time to innovate, market, or rest.
- The "Sweet Spot" (60%–80%): This allows for high revenue production while leaving room for the strategic thinking required of a CEO.
Why Accurate Tracking is a Form of "Internal Control"
At True North Bookkeeping, LLC, we see time tracking as more than just a timer; it’s a vital Internal Control.
The CEO Takeaway
You cannot manage what you do not measure. By separating these two types of hours, you gain a clear view of your Ground Truth—allowing you to spend less time "working" and more time "earning."
- No Leaky Faucets: We help ensure you never leave money on the table by forgetting to log that "quick" 15-minute client call.
- Project Profitability: If you quoted a flat fee for a project but spent 50 billable hours on it, was it actually profitable? Without tracking, you’re just guessing.
- Strategic Hiring: When your team’s billable capacity is consistently hitting 85%, that is your data-driven "Green Light" to hire more help.
