Mastering Law Firm Billing in Canada: The Complete Guide for Lawyers
Law firm billing is the lifeblood of a law practice, with direct ramifications on client satisfaction and cash flow. But billing efficiency is something that many lawyers simply can’t wrap their heads around – the typical lawyer will bill only 3 out of an 8-hour workday, lost to non-billable activities such as administration of billing. For Canadian law practices, billing is not just receiving payment, but it must also be done in accordance with draconian law society rules and professional fee and trust account standards.
Understanding Law Firm Billing
The Importance of Efficient Billing
At its core, law firm billing is how legal professionals turn their work into revenue. A well-run billing process ensures your firm gets paid fully and on time for services rendered. Inefficient billing, on the other hand, can hurt cash flow and even client relationships. Billing problems like inconsistent invoices or delays not only frustrate clients but also lead to lost income for the firm. If a lawyer only bills a fraction of their working day, the firm is effectively leaving money on the table. Efficient billing practices help capture all billable time, minimize write-offs, and shorten the payment cycle – all crucial for a healthy law practice.
Common Billing Challenges for Lawyers
Lawyers in small and mid-sized firms often face several recurring billing challenges. One major issue is time leakage – not all hours worked end up being billed. This can happen due to poor time-tracking habits (e.g. waiting until the end of the week to recreate timesheets from memory and inevitably forgetting some tasks) or under reporting hours out of fear a bill will seem too high. Another challenge is the billing delay: when invoices go out long after the work is done. Slow billing can lead to clients questioning charges (since the work isn’t fresh in mind) and contributes to slower payments. Billing transparency is also a concern – clients may become unhappy if they receive bills that are vague or much larger than expected. This puts pressure on firms to be detailed and upfront about fees to avoid surprises. Additionally, many lawyers feel the administrative burden of billing tasks: preparing invoices, processing payments, and updating accounts can consume significant non-billable time, cutting into the firm’s profitability. Lastly, ensuring compliance with all billing-related regulations (like trust accounting rules or tax reporting) can be challenging without proper systems in place. In summary, while billing is critical, it comes with pitfalls – from lost time and revenue to ethical risks – that lawyers must proactively address.
Billing Models and Fee Arrangements
Hourly Billing
Hourly billing remains the most common fee arrangement for law firms in Canada and elsewhere. The lawyer charges an agreed hourly rate for time spent working on the client’s matter. Every task – phone calls, research, drafting documents, court appearances – is tracked in small increments (often 0.1 hours or 6-minute blocks) and totaled on the invoice. Hourly rates vary widely based on a lawyer’s experience, specialization, and regional market. Senior attorneys bill more per hour than junior lawyers, and big-city rates tend to be higher than small-town rates. The appeal of the hourly billing is its simplicity and the assurance that you are compensated for all the work done. However, it can make costs less predictable for clients, and it puts the onus on the lawyer to diligently record all billable hours. To justify hourly bills, it’s critical to keep detailed time entries describing the work – this shows clients the value they’re getting for the hours charged.
Flat and Fixed Fees
Flat fees (also called fixed fees) charge a single set amount for a specific service or phase of a case, regardless of the actual time spent. This model is commonly used for routine or well-defined legal tasks. For example, a lawyer might charge a flat fee for preparing a simple will or handling a residential real estate closing. Flat fees provide cost certainty for the client – the client knows upfront exactly what the service will cost. For the law firm, flat fees reward efficiency: if you complete the work quickly, you effectively earn a higher rate. But if the matter turns out more complicated than expected, a flat fee could under-compensate the lawyer. Therefore, setting an appropriate flat fee requires experience and a clear scope of work. Lawyers must still ensure any flat fee is reasonable for the work done (performed by professional rules). Flat fees work best for tasks that are predictable in scope, and they are less common in complex litigation or matters with unpredictable twists.
Contingency Fees
In a contingency fee arrangement, the lawyer’s fee is contingent upon the outcome – typically the lawyer takes an agreed percentage of any amount recovered for the client (through settlement or judgment). If the client gets nothing, the lawyer doesn’t charge a fee (though the client may still owe disbursements and taxes). Contingency fees are popular in personal injury and other litigation for clients who cannot afford to pay hourly fees upfront. They align the lawyer’s incentives with the client’s success and improve access to justice for those who might otherwise be unable to pursue a claim. However, because of the potential for very high fees in a big win, law societies impose strict rules on contingency arrangements. In Canada, all contingency fee agreements must be in writing and fully explained to the client. Many provinces also place limits on contingency rates for certain case types – for example, in British Columbia a contingency fee for a personal injury claim arising from a motor vehicle accident is capped at 33%, and some types of family law cases cannot be billed on contingency. These regulations protect clients from unfair deals. When making a contingency arrangement, it’s crucial to clearly explain how the fee will be calculated (and what expenses will be deducted) so the client understands their potential net recovery.
Retainers and Advance Payments
Most law firms request a retainer at the start of a new engagement. A retainer is an advance payment or deposit that the client pays into the lawyer’s trust account. The lawyer then bills their fees against that retainer as work is completed, essentially drawing down those funds to pay each invoice. The client may be asked to replenish the retainer if it becomes low during an ongoing matter, and any unused balance is returned at the end. Retainers ensure the lawyer has funds on hand and reduces the risk of non-payment. Retainers are especially common with hourly billing arrangements. For example, a lawyer might collect an initial retainer (say $5,000) and then bill time against it each month, asking the client to top it up as needed. It’s important to manage retainers in accordance with trust rules – retainer funds must be held in trust and only moved to the firm’s account once fees are earned (an invoice has been issued). Aside from retainers, other alternative fee arrangements are emerging. Some firms offer hybrid fees (a combination of flat and hourly, or a reduced hourly plus success bonus) or even subscription-style models for certain legal services. The key is to align the fee model with the type of matter and the client’s needs. Regardless of the how do lawyers bill model, clarity is paramount – the client should always understand how they will be charged.

Setting Billing Rates and Policies
Determining Your Fee Structure and Rates
Deciding how much to charge is a critical business decision for any law firm. There is no fixed “fee schedule” mandated in Canada (apart from legal aid or court tariffs), so firms must set their own rates based on market conditions and the value of their services. A good starting point is to research the going rates in your region and practice area – for example, what other lawyers of similar experience charge for similar work. This provides a market baseline. Next, consider your own credentials and efficiency: a seasoned specialist can justify higher rates than a newly called lawyer, and if you’ve invested in technology that lets you work faster, you might deliver the same outcome in fewer hours (which can warrant a higher hourly rate to reflect that value). Don’t forget to factor in your overhead costs (office rent, staff salaries, insurance, etc.) – your pricing must cover these to be sustainable. Many firms review their billing rates annually. Inflation and rising expenses mean you should periodically adjust rates rather than charging the same fees year after year. In recent years, some Canadian firms have modestly raised rates but still lag behind inflation, which can erode profitability. The goal is to set rates that reflect the quality and efficiency of your work while remaining competitive and fair to clients.
Billing Policies and Client Communication
Beyond the dollar amount of fees, law firms need clear policies on how billing is handled. Establish a written billing policy that covers when and how you bill, what you bill for, and the payment terms. For instance, decide on your billing frequency (monthly billing is a common cadence for ongoing matters) and payment due dates (e.g. “payment due within 30 days of invoice”). Determine whether you will charge interest on overdue accounts – if so, this must be stated upfront in the engagement agreement. It’s also wise to clarify what types of tasks or expenses will be billed. Commonly, how do lawyers bill for all the time spent on a client’s matter (calls, emails, travel time, etc.) unless otherwise agreed, but some firms choose to write off minor incidental tasks as a courtesy. Make these choices part of your internal policy so everyone in the firm bills consistently. Crucially, communicate all terms to the client at the outset. A comprehensive engagement letter or fee agreement should spell out the billing arrangement: the hourly rates or flat fee, any retainer requirements, how disbursements (expenses) will be charged, and the billing schedule. Getting the client’s informed consent to the fee structure in writing is not just best practice – it’s often an ethical requirement. Professional conduct rules in Canada demand that fees be reasonable and that clients be informed about how fees will be calculated. There should be no surprises or hidden charges. If a client later disputes a bill as too high, the onus will be on you as the lawyer to prove it was fair and agreed upon – another reason thorough documentation is critical. In summary, set your billing policies deliberately and communicate them clearly. This proactive approach builds trust with clients and prevents many billing issues before they arise.
Time Tracking and Billing Efficiency
Timekeeping Best Practices
The foundation of efficient billing is accurate and timely timekeeping. If you don’t capture the work you’ve done, you simply can’t be billed for it. Lawyers should develop disciplined habits for recording time. Some best practices include:
- Record time promptly: Enter your billable hours as soon as a task is completed (or in real time if possible). Waiting until the end of the day or week can lead to forgotten billables.
- Be descriptive: Write clear, specific descriptions for each time entry (e.g. “Researched case law on liability issue – 2.0h” rather than just “Research”). Detailed entries help demonstrate value to the client and jog your memory later.
- Review for accuracy: Before billing, double-check your timesheets for any errors in the hours recorded or typos in descriptions. Even small mistakes can raise client questions and undermine confidence.
Good timekeeping practices ensure you don’t lose revenue through oversight and provide the raw data for fair, transparent bills. Many law societies in Canada emphasize that proper “docketing” of time is one of the best management tools for a profitable practice. Even if you use alternative fees like flat rates, keeping time records is wise – they can justify your fee if it’s ever challenged and help you evaluate the profitability of flat-fee cases.
Boosting Utilization and Reducing Inefficiencies
Another key to billing more (without necessarily working more hours) is improving your utilization rate – the percentage of your workday that is spent on billable tasks. Studies have found that the average lawyer only bills around one-third of their available work hours to clients. The rest of the day is consumed by administrative work, business development, and other non-billable activities. This presents a huge opportunity: if you can convert even one additional hour per day into billable times (by working more efficiently or delegating non-billable tasks), you significantly increase revenue without extending your working hours. Begin by tracking your own utilization, realization, and collection of metrics. Utilization is how much of your available time gets billed, realization is how much of that billed time gets invoiced (after any write-downs or discounts), and collection is how much of the invoiced amounts are ultimately collected from clients. Many small firms see realization rates around 85–90% and collection rates around 90%.

If your firm’s metrics are below these benchmarks, you likely have room to capture more revenue by improving processes. To boost utilization, consider offloading or automating administrative chores – use support staff or technology so lawyers can spend more time on client work. Also, set realistic billing targets (e.g. a certain number of billable hours per week or month) and monitor progress. To improve realization, analyze why any time is being written off: are certain tasks routinely taking longer than expected, or are you giving unnecessary courtesy discounts? Identifying the causes can help you adjust how you scope and price work. To improve collection, ensure your invoices go out promptly and offer convenient payment options (more on that shortly). Continuously measuring these KPIs will spotlight bottlenecks in your billing workflow. With the right adjustments, law firms can significantly increase the share of their work that gets billed and paid – directly improving the bottom line.
Compliance and Ethical Billing Practices
Meeting Professional Standards
Lawyers must adhere to strict professional rules on fees. The overarching principle is that a fee must be fair and reasonable for the work done. Relevant factors include the time and effort required, the complexity and importance of the matter, the results obtained, and the lawyer’s experience. Equally important is full disclosure: you must clearly explain your fees and obtain the client’s agreement (ideally in writing) at the outset. There should be no surprise charges or undisclosed costs. If a client later challenges a bill as too high, it may be reviewed by a court assessment officer, and you will have to justify that the fee was reasonable and agreed upon. Being upfront and transparent from the start is the best way to avoid such disputes.
Trust Funds and Tax Obligations
One distinctive aspect of legal billing in Canada is the handling of client trust funds. When a client gives you money in advance – whether as a retainer for fees or to cover upcoming disbursements – those funds must be kept in a designated trust account and not comingled with the firm’s own money. You can only transfer such funds from a trust to your general account once you have rendered an invoice for work performed or expenses incurred. Strict trust accounting rules require detailed records of every trust deposit, withdrawal, and the remaining balance per client. Law firm billing software (like Runsensible) can help automate trust ledger management to ensure you don’t accidentally breach these rules. Another compliance element is taxes. Lawyers are required to apply federal/provincial sales tax to their fees in most cases. For example, a law firm in Ontario must add HST (13%) to its legal services charges and then remit those tax amounts to the government. Failing to charge the appropriate GST/HST or PST on your invoices not only shortchanges the tax authorities but can lead to penalties. Be sure your billing system calculates taxes correctly and that your invoices clearly separate fees, disbursements, and applicable taxes. Finally, be mindful of what expenses you bill as disbursements. You should only seek reimbursement for actual costs incurred on the client’s behalf (court filing fees, government charges, expert reports, courier, etc.), typically without any markup. It’s considered unethical to make a profit on disbursements. In short, a compliant billing practice means charging reasonable fees, documenting everything, safeguarding client monies in trust until earned, and following all tax and disclosure rules. This protects your clients and keeps your firm in good standing with regulators.
Improving Collections and Embracing Technology
Streamlining Client Payments
Even after you have billed for your work, the final step is getting the money in the door. Many law firms struggle with overdue invoices – over half of firms report regular late payments, and on average, only about 85–90% of billed fees are ultimately collected. How can you tighten that gap? A few practical strategies can make a big difference. Send invoices on a consistent schedule so clients know when to expect your bill. Make sure your bills are clear and easy to understand – clients are more likely to pay promptly if they see exactly what work was done and why it mattered. Also, they offer convenient payment options: many clients will pay faster if they can click a link to pay by credit card or e-transfer, rather than having to mail a cheque. You should also promptly follow up on overdue bills with polite reminder emails or calls. Often, a gentle nudge at 15 or 30 days past due will result in payment. If a client is having cash flow issues, you might offer a temporary payment plan or schedule of installments rather than letting the bill go unpaid. Lastly, maintaining a retainer for ongoing matters (and requiring it to be replenished when low) can ensure you always have funds on hand for fees, minimizing the risk of non-payment. By being proactive and client-friendly in your billing process, you’ll find far fewer payments dragging past their due dates.
Leveraging Legal Billing Technology
The administrative load of billing and collections can be drastically reduced by using the right software tools. In today’s market, legal practice management systems like Runsensible streamline the entire billing workflow. Instead of manually entering time on paper or spreadsheets, you can use built-in timers and digital timesheets that link directly to each client’s matter. Invoices can be generated with a few clicks, pulling in all your recorded time and expenses and calculating taxes automatically. This not only saves time but also minimizes mistakes (such as math errors or omitted billable entries). Modern billing software also facilitates faster payments. For example, Runsensible provides a secure client portal where clients can view invoices and pay online via credit card or bank transfer. By offering an intuitive online payment option, you remove friction and often get paid much sooner. A good legal billing system will also help with trust accounting compliance – for instance, when you bill against a trust retainer, the software can automatically deduct from the client’s trust balance and update the ledgers, preventing any accidental mishandling of trust funds. Automation is another major benefit: you can set up automatic invoice reminders for overdue accounts, schedule recurring billing for payment plans, and generate financial reports on demand. Finally, all your billing data is centralized and backed up, making it easy to track performance and spot trends. Embracing technology turns billing from a tedious chore into an efficient, integrated part of your practice. You’ll spend less time chasing invoices and more time on substantive legal work, and your clients will appreciate the convenience and professionalism that a modern billing system provides.

FAQs
How do lawyers bill their clients?
Most lawyers bill clients by the hour, meaning they charge a set rate for each hour of work on a case. Hourly billing is common because it’s straightforward and ensures you get paid for your time. However, depending on the matter, lawyers may also use alternative fee arrangements. For instance, some services (like a straightforward will or contract review) might be offered for a flat fee. In contingency cases (common in personal injury), the lawyer gets a percentage of the settlement or award – only if the case is successful.
What is the best billing model for a small law firm?
There isn’t a one-size-fits-all answer – the optimal billing model depends on your practice area and client needs. Small firms often use hourly billing because it’s straightforward and ensures you get paid for your work. That said, flat fees can be great for simple, predictable services where you can confidently set a price (clients love the certainty).
How can I increase my firm’s billable hours and efficiency?
Use a diligent time-tracking system so no billable task goes unrecorded – a timer or app helps you log time in real time and avoid forgetting work. Next, reduce the hours lost to non-billable chores: delegate administrative tasks or use automation (for instance, let software handle routine invoicing and scheduling). With better organization and smart use of technology, you can devote more of your day to billable client work.
What ethical rules govern legal billing in Canada?
In Canada, lawyers must follow their law society’s code of conduct regarding fees and billing. The overarching rule is that fees must be fair and reasonable for the services provided. All fee arrangements should be explained to the client in advance and agreed upon (ideally in a written retainer agreement).
How can I reduce late payments from clients?
Start by sending invoices on a consistent schedule so clients know when to expect your bill. Make sure your invoices are clear and detailed, which helps prevent disputes or confusion. Offering convenient payment options can also speed up collections – for example, allow clients to pay by credit card or online transfer, as these methods make it easy for them to pay immediately. It’s important to follow up on overdue bills promptly but politely (often a friendly reminder at 15 or 30 days overdue will do).
