What You Need To Know About Sales Commissions

Sales commissions can be a great way to motivate your team, reward performance and grow revenue. But in Australia, there are important legal rules around how you structure, document and pay commissions to employees or contractors.

If you’re thinking about introducing commissions, or you want to tidy up your current plan, this guide walks you through the key decisions, compliance traps and documents to have in place - so you can reward results without risking a legal headache.

What Are Sales Commissions And How Do They Work?

Sales commissions are variable payments tied to performance. They’re commonly calculated as a percentage of sales value, revenue collected, gross profit or a per-deal flat amount.

You can use commissions for internal employees (as part of their remuneration package) or with external sales agents and referrers. The structure should be clear, measurable and realistic - and legally compliant.

Common Commission Models

• Percentage of revenue: A set % of invoice value or cash received.
• Percentage of margin: A % of gross profit (often used where pricing varies).
• Tiered or accelerators: Higher % once targets or thresholds are hit.
• Flat fee per sale: A fixed amount per qualifying deal.
• Hybrid: A lower base salary plus commission and occasional bonuses.

Whatever model you choose, your plan should define when a commission is “earned” (for example, on contract signing, delivery, or once the customer pays), how returns/cancellations are handled, and any eligibility rules (probation, employment status, minimum performance standard).

Should You Pay Commission, Salary Or Both?

Many Australian businesses use a hybrid approach: a base salary (for stability and minimum entitlements) plus a commission (to drive performance). In many industries, this offers the best balance between motivation and fairness.

Salary Plus Commission

Pros: Predictable income for staff, easier to comply with minimum wage and award obligations, attractive to experienced sales talent.

Cons: Higher fixed costs for you than pure commission, and you still need a well-designed plan to drive results.

Commission-Only (Employees)

Commission-only arrangements are tightly regulated and not suitable in many cases. You still need to comply with modern awards or enterprise agreements (if they apply), and ensure minimum entitlements are met across a pay period or assessment period. If you’re considering this path, you’ll want explicit, compliant terms in an Employment Contract and a detailed commission plan.

External Agents, Referrers Or Contractors

Sometimes it makes sense to work with independent sales agents or referrers. In those cases, your relationship should be documented with a tailored Commission Agreement or Referral Agreement, and you’ll want to carefully consider whether they are truly a contractor and not an employee in substance.

Do Commission Plans Need To Comply With Australian Employment Law?

Yes. If the salesperson is your employee, your commission scheme sits on top of your Fair Work obligations. Even with contractors, other legal rules apply. Here are the main issues to get right.

Modern Awards And Minimum Entitlements

Many sales roles fall under a modern award (for example, retail, real estate or clerical awards). You need to check coverage and make sure your commission plan doesn’t undermine minimum entitlements - such as minimum rates, ordinary hours, overtime/penalty rates or allowances. A payroll review and regular award compliance check is essential if an award applies.

Salary Offsets And Guaranteed Minimums

Where you pay a base salary plus commission, be clear how the salary and variable pay interact. If you plan to offset certain payments, ensure your wording is legally sound - poorly drafted set-off provisions can be unenforceable. It’s worth understanding how set-off clauses work in Australia and getting tailored wording in your contracts.

Superannuation On Commissions

In most cases, commissions paid to employees form part of Ordinary Time Earnings (OTE), which means superannuation is payable. This can be a surprise if you’ve been budgeting commission only as cash cost. Build super into your plan and payroll processes from day one.

Leave, Overtime And Penalties

Employees still accrue annual and personal leave on their ordinary hours. If an award applies, overtime and penalty rates may also be relevant - your commission plan doesn’t replace those entitlements unless it’s structured and worded appropriately, with clear compliance.

Deductions, Clawbacks And Chargebacks

Be very careful with clawbacks (for example, if a customer cancels or defaults). The Fair Work Act’s section 324 restricts deductions from employee wages. If you want to recoup or adjust commissions after payment, you usually need the employee’s written authorisation and you must meet strict rules about whether the deduction is principally for the employee’s benefit. Many “chargeback” practices are risky without precise, compliant terms.

When Is A Commission “Earned”?

Define clear earning points: order execution, supply/delivery, invoice issuance, or customer payment. Also decide whether commissions are paid on booked revenue or cash collected - and how disputes or partial payments are handled. This clarity reduces arguments and supports consistent payroll treatment.

Transparency And Record-Keeping

Employees should be able to see how their commission is calculated, including rates, eligible products, territory rules, split deals and any adjustments. Keep accessible plan documents, monthly statements, and calculation workpapers. Good records will help you if a dispute arises and support audit or award compliance checks.

How To Structure A Commissions Policy Or Agreement

Whether you embed commission terms in your employment contract or create a standalone policy/plan, aim for a clear, complete and practical set of rules. A separate plan that’s incorporated by reference into the contract is common - it makes updates easier while preserving legal certainty.

Step 1: Define Objectives And Metrics

Choose what you want to incentivise: revenue, margin, product mix, new business vs retention, collections, or teamwork. Keep the metric simple, measurable and within the salesperson’s influence.

Step 2: Set Rates And Thresholds

Decide your base rate, tiers and accelerators, and whether there’s a cap. Make sure your economics work in best- and worst-case scenarios. If you cap commissions or apply clawbacks, say so plainly and consistently.

Step 3: Clarify Eligibility And Earning Events

State when commissions are earned and payable, probation eligibility, treatment during leave, and what happens on termination. Describe how returns, cancellations and non-payment are handled. If you run team splits or house accounts, explain those rules too.

Step 4: Document It Properly

For employees, include the commission plan in an Employment Contract and attach a detailed policy or schedule to avoid ambiguity. For external contractors or agents, use a tailored Commission Agreement that covers scope, exclusivity, territory, invoicing and GST, IP, confidentiality and termination.

Step 5: Review For Compliance

Check awards, superannuation, deductions and payment timing. Ensure set-off and clawback wording is legally sound. If in doubt, get experienced help and lock in compliant templates like an Employee Commission Agreement designed for Australian law.

Commission-Only, Contractors And External Agents: What’s Different?

Commission-only arrangements raise specific risks. Here’s what to consider if you’re stepping outside the salary-plus-commission model.

Commission-Only Employees

It’s not unlawful per se, but you must ensure the employee doesn’t fall below minimum entitlements over the relevant period (often a pay period, sometimes longer under a specific award or agreement). Many businesses set a guaranteed minimum or “safety net” to manage this risk. Always pair a robust plan with strong award and payroll controls.

Independent Contractors And Agents

Using independent salespeople can be flexible, but misclassification risk is real. If you control hours, methods, and provide core tools, a “contractor” may in fact be an employee in substance. In that case, you could face back pay, super and penalties.

If you genuinely use contractors, document the relationship with appropriate terms - scope, independence, GST and ABN requirements, insurance, confidentiality, IP ownership, and termination rights. A well-drafted Commission Agreement goes a long way to setting expectations and reducing disputes.

Transitioning Plans Or Changing Targets

If you update plans or targets, give reasonable notice and avoid retrospective changes. Explain why changes are made, provide transition rules and consider timing (e.g. implement from a new quarter). Inconsistent mid-period changes create mistrust and legal risk.

What Legal Documents Will I Need?

The right paperwork helps you stay compliant and avoid disputes. Most businesses introducing commissions should consider:

• Employment Contract: Sets base terms for employees, incorporating reference to the commission plan, confidentiality, IP and termination.
• Employee Commission Agreement: A tailored schedule or policy that sets out the commission formula, thresholds, eligibility, when earnings vest and how adjustments work.
• Commission Agreement (for agents/referrers): Covers scope, territory, exclusivity, rate, invoicing, GST, confidentiality, IP and termination.
• Incentive Policy: A supporting policy for bonuses, SPIFFs or contests - detail eligibility, periods, and how awards are verified and paid.
• Set-off clauses: Contract wording to properly offset above-award payments against award entitlements where lawful and appropriate.
• Confidentiality And IP Terms: Usually embedded in your employment or contractor agreements to protect customer lists, pricing and playbooks.
• Data And Privacy Settings: If your team uses CRM and customer data, ensure you have appropriate internal policies and external notices (e.g. a website Privacy Policy) and access controls.

Not every business needs every document, but most will need a core employment or contractor agreement plus a clear commission plan that’s reviewed regularly.

Common Pitfalls And How To Avoid Them

Commission schemes can fail not because of bad intent, but because of unclear rules or non-compliance. Here are the issues we see most often - and practical ways to prevent them.

1) Ambiguity Around When Commission Is Earned

Fix: Define the earning event and payout timing (e.g. “earned on cleared funds received” and “paid in the next monthly pay cycle”). Spell out how partial payments, write-offs and refunds are treated.

2) Unlawful Deductions And Chargebacks

Fix: Before any clawback, check section 324 and ensure you have an informed, written authorisation that meets the legal test. Consider deferring vesting until a deal is “safe” rather than recouping after payment - it’s cleaner and lower risk.

3) Underpaying Against Award Minimums

Fix: Regularly audit total earnings and roster patterns, run reconciliation checks, and stay on top of award compliance. If you use offsets, ensure the wording and payroll calculations actually work.

4) Missed Super On Commissions

Fix: Treat commissions as part of Ordinary Time Earnings (OTE) unless you have a clear, defensible exception - and set up your payroll system to calculate super correctly.

5) Territory, Split Deals And Disputes

Fix: Include a simple tie-breaker rule for conflicts (e.g. “first CRM registration wins”), define how split credits work, and state who decides on exceptions.

6) Changing Targets Mid-Period

Fix: Avoid retrospective changes. If necessary, communicate early, provide reasonable notice, and document changes in an updated plan attached to the employee’s agreement.

7) Contractor Misclassification

Fix: If your “contractor” looks and feels like an employee, reconsider or adjust the arrangement. Use proper contractor documentation and maintain independence in practice.

Key Takeaways

• Sales commissions can power growth, but they must sit on top of Australian employment law - check awards, minimum entitlements, super and deduction rules.
• Define clear earning events, payout timing, eligibility and adjustment rules to reduce disputes and payroll errors.
• If you plan to offset or claw back amounts, ensure your wording and processes align with the law (including set-off and Fair Work deduction rules).
• Document your plan properly with a compliant Employment Contract and an Employee Commission Agreement or, for external salespeople, a Commission Agreement.
• Review your plan regularly for award compliance and super treatment, and keep transparent records your team can understand.
• When in doubt, get tailored advice early - a small tweak to your plan now can save significant cost and disputes later.
