Key takeaways
- Start from the cost of a delivered hour, including the hours nobody bills, and work upward to the fee.
- Fixed fees reward firms that scope tightly and deliver efficiently, and punish firms that do not.
- Retainers smooth cash and deepen relationships, but only when the scope inside them is written down.
- Scope creep is a pricing problem, so the change process belongs in the proposal, not in the argument afterwards.
Professional firms sell time and judgement, and both are hard to price. Most firms in BC start with an hourly rate borrowed from a competitor or a former employer, then add fixed fees and retainers as clients ask for them, without ever checking whether any of those arrangements make money.
We work with consultancies, agencies, engineering practices, law firms and design studios on exactly this question. The method has four parts: know what delivery costs, choose the pricing model that fits the work, protect scope, and measure realisation.
Know the cost of a delivered hour
Take the total cost of employing each fee earner for a year, including salary, employer payroll costs, benefits, software, training and a seat in the office. Divide by the hours that person can realistically bill after holidays, internal meetings, business development and administration. The result is the loaded cost per billable hour, and it is the floor under every rate you quote.
Then add the firm's overhead, which is the partners' non-billable time, administrative staff, rent, insurance, marketing and professional fees. Spread it across the firm's expected billable hours. Only after direct cost and overhead are covered does a fee produce profit. Ask your CPA for last year's figures by category so this is built on actuals.
Choose the model for the work, not the client
Hourly billing fits open-ended advisory work and disputes where the path cannot be known in advance. It protects the firm from scope risk and gives the client every incentive to limit the work. Fixed fees fit well-defined deliverables that you have done many times, such as a website build, a tax structure review alongside a client's accountant, or a standard valuation report. The firm takes the efficiency risk and keeps the reward.
Retainers fit ongoing, recurring work with a predictable rhythm, such as monthly reporting, ongoing marketing or an advisory seat. They smooth cash flow and make planning possible. The trap is a retainer whose scope was never written down, which drifts into unlimited access for a fixed price.
Price the fixed fee from the inside out
Estimate the hours by role for each stage of the engagement, multiply by loaded cost, add overhead recovery and the margin the firm has decided it needs. Then add a contingency for the surprises every project has. That is the floor. Above the floor, the fee can rise toward the value the client receives, and for work where the outcome is large relative to the effort, it should.
Write down the assumptions the price rests on, such as the number of review rounds, the data the client will provide and the decision dates. These assumptions become the basis for any change request.
Build the change process into the proposal
Scope creep is rarely malicious. The client asks a small question, the team answers it, and twenty small questions later the fixed fee has absorbed a week of unpaid work. The fix is a sentence in every proposal that explains how requests outside the written scope are handled, and a habit of raising them the same day rather than at the invoice.
Internally, track hours against every fixed fee and retainer weekly. When a project reaches the hours you budgeted and is not finished, that is the moment for a conversation with the client, not the end of the month.
Measure realisation and utilisation
Realisation is the fee you actually collected divided by the hours you worked at your standard rates. Utilisation is billable hours divided by available hours. A firm can be fully busy with poor realisation, which means it is giving work away, or have excellent realisation and low utilisation, which means it needs more clients, not higher rates. Both numbers belong on the weekly pack, by person and by service line.
Over a few quarters this data tells you which services to raise, which to fix and which to stop offering.
Mistakes that quietly erode fees
- Quoting the hourly rate the market seems to expect rather than the rate the cost structure requires
- Writing fixed fee proposals without an hours estimate behind them
- Retainers with no written scope and no monthly reconciliation of hours used
- Discounting the first engagement to win the client and never restoring the rate
- Senior people doing junior work at a senior cost and a junior price
