How to track billable hours effortlessly

If you’re a freelancer or a consultant, you know how important it is to track your billable hours. Billable hours are the time you spend working on a client’s project that you can charge for. Your billable hours directly affect your income and reputation.

But it’s not as simple as it sounds.

It involves considering factors like your rate, scope of work, and invoicing system. You also need to differentiate between billable and non-billable hours, which can be tricky.

Having a reliable system in place to track those hours makes the job far easier. It can help ensure accuracy and measures your personal productivity, making sure the effort you’re putting in is paying off.

What are billable hours?

A billable hour (or billable time) is the time you spend working on a client’s project that you can invoice. This includes time on tasks like coding, designing, writing, or any other work that contributes to the completion of a project.

Billable hours aren’t one-size-fits-all.  The type of freelancer or consultant you are, the nature of the project, and the agreed-upon rate all play a role in determining your billable time.

A clear (and ideally, written) agreement with your client about what does and does not fall under billable hours sets a solid foundation for everyone.

Why billable hours matter

Tracking billable hours provides a measure of productivity. By closely monitoring your billable time, you can better understand how you spend your time and identify areas for improvement.

Billable hours also directly impact your profitability. Accurately tracking billable hours ensures that all the work performed for a client is accounted for and invoiced. By eliminating discrepancies and underbilling, you capture the full value of your services, which means increased revenue for your business.

Lastly, billable time plays a role in client satisfaction. Transparently sharing your billable hours gives clients a clear understanding of where their money is going, which can build trust and foster long-term relationships.

Billable vs non-billable hours

So what makes up billable and non-billable hours? Non-billable hours are spent on activities that don’t directly relate to a client’s work. This might include time spent on administrative tasks, business development, or breaks. While these activities are essential for your business, they aren’t chargeable to a client.

It’s helpful to categorize your work day into these two types of tasks to manage your billable and non-billable hours effectively.

For instance, you might spend the morning on billable work, like designing a client’s website, and the afternoon on non-billable tasks, like replying to emails or working on your marketing strategy.

While non-billable hours are necessary to keep your business running, minimizing and optimizing these tasks as much as possible is important. Every hour spent on non-billable work is an hour you could have been earning revenue.

Here are five steps to implement to bill for your hours accurately.

Step 1: Set your rate

First, answer one key question: How much should you charge for your time?

To calculate your billing rate, you’ll want to consider your expenses, including rent or mortgage, utilities, groceries, and other day-to-day costs. And don’t forget about your desired profit margin. After all, you’re in this business to make money, right?

You’ll better understand your cost rate once you’ve added up your expenses. Then, it’s time to set your hourly rate. This rate should reflect your skills, experience, and market value. It’s all about balancing what you need to earn and what clients are willing to pay.

For example, let’s say you’re a freelance web developer who wants to charge $50 per hour for your services. Your cost rate is your total monthly expenses divided by the number of hours you work per month.

To calculate your cost rate, you first need to add up money going out each month:

  • Rent: $1200
  • Utilities: $350
  • Groceries: $300
  • Internet: $90
  • Software subscriptions: $125
  • Health insurance: $450
  • Gas: $120
  • Pets: $200
  • Funds set aside for savings: $500
  • Depending on where you live, you may need to account for taxes, services, and other government fees. We’re leaving that expense out for simplicity, but be sure to factor it in.

Your total monthly expenses are $3,335.

Now calculate the hours you work every month (or want to work). If you work 40 hours per week multiplied by four weeks, that’s 160 hours.

3335 / 160 = 20.84 (rounded to two decimal places).

Your cost rate at this point is $20.84 per hour. You must earn this minimum to cover your expenses and save money.

However, you also want to profit from your work, so you’ll need to add a profit margin to your cost rate. A common profit margin for freelancers is 20-30%. For this example, we’ll use 25% (or 0.25). You can multiply your cost rate by 1.25 to get your new hourly rate.

Your hourly rate would be $20.84 x 1.25 = $26.05.

how to calculate your hourly rate

For simplicity’s sake, let’s round up to $27/hour. Charging this rate should help you meet your living cost and make a profit. You can think about charging more if you have a lot of expertise and a strong portfolio. Consider your skills, background, and the going rate in your chosen market and field.

On the other hand, if you are new to the field and have less experience, you might want to charge less than $27 per hour to attract more clients and build your reputation (say $25/hour). Ultimately, it’s up to you to decide what your time is worth and what clients are willing to pay.

Step 2: Communicate clear terms with clients

Transparency is important in any working relationship, and it’s no different when it comes to chargeable time. Before diving into a project, ensure you have a clear agreement with your client. This agreement should cover your hourly rate, the invoicing schedule, payment terms, and the scope of work. Here’s a full breakdown of the essentials that any work agreement should include:

  • Your hourly rate: Ensure your rate is fair, competitive, and reflects your skills and experience.
  • The invoicing schedule: How often will you send invoices to your client? Will it be weekly, monthly, or after each milestone? Specify the frequency and the due date for each invoice.
  • The payment terms: How will your client pay you? Will it be by check, bank transfer, or online payment? Clarify the payment methods and the consequences of non-payment.
  • The scope of work: What are the deliverables and expectations for the project? What are the deadlines and the quality standards? How will you handle changes or revisions? Define the project’s scope and boundaries, and avoid scope creep.

To create and manage your agreements, you can use contract workflow tools like PandaDoc and DocuSign.

Step 3: Divide projects into subtasks

Successful project management starts by breaking the overall deliverable into subtasks — especially if you’re working on multiple projects simultaneously. Partitioning your workload allows you to track the time spent on each.

A robust tracking system should allow you to break down projects into subtasks and track multiple projects for each client. This level of granularity can help you understand where you spend your time and makes for more accurate client billing practices.

You should also record non-billable hours. This categorization helps in assessing productivity, profitability, and operational efficiency.

For instance, let’s say you are working on two projects for two different clients: A website redesign for Client A and a logo design for Client B.

Website redesign for Client A:

  •   Research and analysis
    • Gather client assets
    • Research market
    • Research competitors
    • Collect user data through analytics
  •   Wireframing and prototyping
  •   Coding and testing
    • Write code
    • Code review
    • Unit testing
    • Integration testing
  •   Deployment and maintenance

Logo design for Client B:

  •   Concept and sketching
    • Hand-draw initial designs.
    • Refine chosen sketches.
  •   Vectorizing and refining
    • Convert sketches to vector graphics.
    • Initial digital draft.
  •   Presentation and feedback
  •   Revision and delivery
    • Prepare final files (different formats/sizes).
    • Deliver to the client.

Having task management in place transforms large projects into manageable assignments. Using a time-tracking app will elevate your project management efficiency. This integration lets you meticulously monitor time spent on each subtask, project, and client, so you can know every minute is accounted for when you’re ready to invoice your client. Additionally, it offers insights into how your time is allocated, so you can identify areas for optimization.

Step 4: Invest in a reliable billable hours tracker
