Consultants and professional service firms sell expertise rather than inventory, but their accounting is not necessarily simple. Revenue may be billed hourly, by milestone, on retainer or through fixed-fee engagements. Partners and employees may work across several clients, expenses may be reimbursable and cash receipts may lag behind work performed.
A useful accounting system should show not only total income and expenses but also the profitability and cash position of the underlying engagements.
Billing structure drives the accounting process
The first step is to define how revenue is earned and invoiced. Common arrangements include:
- Hourly or daily billing.
- Fixed-fee projects.
- Milestone-based billing.
- Monthly retainers.
- Success-based or contingent elements.
- Reimbursable client expenses.
The books should distinguish invoices issued, cash received, work completed but not yet billed, deposits and deferred amounts where relevant. This allows management to see whether revenue growth is being converted into invoices and collections.
Engagement profitability should be visible
A firm can be busy while earning inadequate margins. Time, contractor cost, travel and project-specific expenses should be linked to the relevant engagement wherever practical.
A monthly engagement report may show billed revenue, unbilled work, direct labour, subcontractor cost, reimbursable expenses and contribution margin. This helps the firm price future work, identify scope creep and decide which services or clients deserve greater focus.
Accounts receivable requires active management
Professional service firms often carry significant receivables because delivery occurs before collection. An ageing report should separate current, overdue and disputed invoices and identify the person responsible for follow-up.
Retainers, deposits and progress billing can reduce working-capital pressure, but the accounting should clearly distinguish amounts earned from amounts still held against future services.
GST/HST responsibilities depend on the services and revenue
Most consulting services supplied in Canada are taxable for GST/HST purposes. For most businesses, registration becomes mandatory when taxable revenues exceed the applicable small-supplier threshold. The place-of-supply and zero-rating rules may also matter where clients are located outside the province or outside Canada.
The invoice system should apply the correct tax treatment, and the GST/HST account should be reconciled to returns filed and payments made.
Business structure affects reporting and tax compliance
A sole proprietor generally reports business or professional income and expenses using Form T2125. An incorporated practice files a corporate tax return and must maintain separate corporate books, bank accounts and shareholder records.
Incorporation does not by itself determine whether a person is an employee or independent contractor, nor does it eliminate the need to review owner compensation, shareholder loans and personal expenses paid by the company.
Family trusts and professional-practice structures need separate records
Where shares of an incorporated practice or investment assets are held through a family trust, the trust should maintain records that are separate from the corporation and the individual practitioners. Dividends, capital gains, loans, allocations and distributions should be supported by resolutions, trust records and beneficiary information.
Where filing is required, the annual compliance may include Form T3RET, Schedule 15, T3 slips and the T3 Summary, in addition to the corporation’s T2 return and the practitioners’ personal returns. The structure should be reviewed annually because trust reporting exceptions and bare-trust rules are not static.
Common accounting issues in professional practices
- Personal and business expenses paid from the same account.
- Unrecorded work in progress or delayed billing.
- Client advances recorded directly as revenue.
- Reimbursable expenses included in overhead without recovery tracking.
- Contractor payments not reconciled to agreements or information slips.
- No visibility over profitability by client or engagement.
- GST/HST collected but not separated from operating cash.
A practical monthly reporting package
- Revenue billed and collected during the month.
- Unbilled work and upcoming milestones.
- Receivables ageing and collection actions.
- Direct cost and margin by engagement.
- Operating expense trends.
- Owner compensation and shareholder balances.
- GST/HST, payroll and income-tax provisions.
- Short-term cash forecast.
