How to Structure a Commission Only Sales Position: Legal Tips & Best Practices

Commission-only sales roles have become an increasingly popular way for UK businesses – from fast-paced startups to established companies – to drive sales performance and growth. If you’re thinking about introducing a commission-only sales position, you’re no doubt hoping to attract ambitious team members and reward results. Done right, this remuneration structure can help you scale your business and align incentives all round.

But as with any business decision, the setup isn’t just about motivating your future sales superstars. There are legal, practical, and strategic considerations to get right from day one to ensure your business is protected, your team are fairly compensated, and disputes are avoided down the track.

In this guide, we’ll break down what a commission-only sales position is, the main ways to structure these roles, the key legal issues every UK employer should know, and best practices for setting up effective (and compliant) commission-based pay. Whether you’re hiring your first rep or building out a bigger team, read on for all you need to know.

What Is a Commission Only Sales Position?

A commission-only sales position is one where an employee (or sometimes contractor) earns their income entirely from commissions – meaning payments based on measurable outcomes, usually the amount of sales they generate. There’s no regular base salary in these roles; every £ earned is a direct reward for making sales happen.

Why would businesses choose this option? The short answer: incentive. Commission-only structures mean higher earnings for higher performance, helping to motivate your team and keep them focused on your business goals. It also protects your cashflow, as you’re only paying out when your business is bringing in revenue.

However, while the upside for employers can be significant, commission-only positions are not without risk – both in terms of team motivation (especially during lean sales periods) and legal compliance. So, let’s break down the main types of commission pay and how to approach them safely.

How Do Commission-Based Payment Structures Work?

There’s no one-size-fits-all approach to commission pay. In fact, most businesses customise commission schemes to suit their industry, sales cycle, and the experience level of their team.

Here are the most common commission structures used in UK businesses:

• Salary Plus Commission: The safest option for employee stability. Staff receive a base wage (e.g. £25,000 per year) plus commission as a percentage of their sales. The commission can be a flat rate (e.g. 10% of each sale) or a tiered amount based on performance.
• Straight Commission (Commission Only): No base pay at all; the employee’s total remuneration is tied to sales results. For example, an agent might earn 20% of everything they sell, but nothing if there are no sales.
• Graduated or Tiered Commission: The commission rate varies based on performance, seniority, or targets. For example, a new starter earns 5% commission, while experienced staff earn 15% or have higher baseline targets.
• Team- or Company-Based Commission: Individual bonuses may be linked to collective performance, to encourage teamwork. For example, a sales team might split a bonus if the company’s targets are achieved.

Each option has its pros and cons when it comes to attracting sales talent, managing workforce risk, and budgeting. Importantly, what you choose also determines your legal obligations, especially regarding minimum wage law and employment rights.

What Legal Issues Should I Consider For a Commission Only Sales Position?

It’s crucial to get the legal side of commission-only roles right before you offer (or accept) such a job – the risks of getting this wrong can be significant, ranging from employment disputes to regulatory fines. Let’s break down the key issues:

Employment Status: Employee or Contractor?

First up: decide whether your commission-only salesperson is an employee (with full employment rights) or a contractor (with more autonomy, but fewer protections). This isn’t just a label you pick–UK employment law will look at the reality of the relationship, not just what your contract says.

If you’re treating someone as an employee (for example, you direct their hours and provide equipment), they’re likely entitled to statutory rights, such as paid holiday, minimum wage, and pension contributions.

True self-employed commission sales agents have more freedom: they choose how and when to work, often sell for multiple businesses, and provide their own equipment. However, trying to use commission-only ‘contractor’ labels to skirt employment law can get you into hot water, so seek advice if you’re unsure. For more details on these distinctions, see our article on Employee vs Contractor.

Minimum Wage Requirements

Perhaps the single biggest risk with straight commission roles is breaching minimum wage obligations. In the UK, all employees (and most workers) are legally entitled to earn at least the National Minimum Wage/National Living Wage for their age group.

This means that, if you have an employee on a commission-only contract, their total gross pay across their working hours must not fall below the legal minimum. You’ll need to keep careful records of hours worked and sales made to prove this.

If, in any pay period, their commission earnings don’t hit minimum wage, you must top them up. Failing to do so can result in back payments, fines, and legal action.

Tip: In low-volume or unpredictable sales environments, a salary-plus-commission model can help keep you compliant and attractive to new hires.

Making Commission Terms Contractually Clear

To protect both your business and your sales staff, it’s essential to document commission arrangements in a clear, professional employment contract or, if genuinely self-employed, in a contractor agreement. Don’t try to ‘wing it’ on an informal arrangement – vague promises of commission nearly always lead to dispute.

Your agreement should specify:

• Basis of commission: What triggers payment (sales closed, revenue received, contracts signed, etc.)
• Commission rate/structure: List the exact percentages, any thresholds, and tiers
• Timing of payment: When and how often commission is paid out (e.g. monthly, quarterly, after client payment received)
• What happens on termination: Is unpaid commission owed for deals in progress? Is there a clawback for cancelled sales?
• Any exclusions: Are certain products, territories, clients, or types of sale excluded from commission calculations?

Employees typically prefer commission schemes to be a contractual right, as this provides enforceable certainty. Employers may be tempted to leave commission policies as discretionary or set out in a staff handbook – but keep in mind this will make the role less attractive to top candidates.

We recommend always using a professionally-drafted commission agreement that covers all bases and is fair to both sides.

Transparency and Dispute Prevention

The best commission structures are those that are transparent, straightforward, and easy to understand on both sides. Ambiguous rules often lead to loss of motivation, complaints (especially if a commission payment is missed or miscalculated), or even tribunal claims.

If you’re considering a team-commission or tiered approach, be especially clear about who qualifies for what share and how performance is measured.

It's also a good idea to address scenarios such as returns/cancellations, and whether sales achieved during notice periods or soon after employment is terminated will still attract commission. Our employee commission agreement guide has more details on what to include.

Other Key Legal Requirements

Several broader rules also apply when structuring commission-only roles in the UK:

• Holiday Pay: Employees must still accrue holiday pay, even if 100% commission-based. Your records will need to show how holiday pay is calculated for fluctuating earnings.
• Equality Act 2010: Incentive pay schemes must not be discriminatory. That means no commission rules that (even indirectly) favour or disadvantage any group based on a protected characteristic (e.g. gender, race, disability).
• Statutory Paid Leave: Sick, parental and other statutory leave pay should be calculated based on average commission earnings as well as base pay (where applicable).
• Notice and Final Pay: Clearly explain what happens to outstanding commission if the employee resigns or is dismissed, and ensure any deductions or clawbacks comply with the Employment Rights Act 1996.

If you’re in a regulated industry (e.g. financial services), check for any additional requirements on pay structure.

Best Practices For Structuring a Commission Only Sales Position

Now that we’ve covered the "need-to-knows" for compliance and risk management, here are our top tips for putting a commission scheme into practice:

• Keep It Simple and Transparent: Make sure your rules are easy to understand and explain to every new hire.
• Benchmark Your Scheme: Research what similar businesses are offering. Uncompetitive commission rates or unrealistic targets will make attracting or retaining top sales talent hard.
• Tie Pay To What Matters To Your Business: Make sure performance metrics are truly aligned with your goals – do you want more customers, bigger contracts, higher profit products sold?
• Review Regularly: As your business grows, targets or rates may need to change. Communicate these adjustments in writing and with reasonable notice.
• Get The Contract Professionally Drafted: Avoid free templates – commission agreements need to be tailored to your business, and cover common disputes with clarity.
• Stay Compliant With Employment Law: Always double-check that your commission-only roles will meet minimum wage and holiday pay rules, especially as sales volume fluctuates.
• Communicate Clearly and Train Effectively: Set expectations early, support new staff, and make sure managers are confident explaining commission calculations.

What Else Should UK Employers Consider?

While commission-only structures can be powerful growth tools, they’re not right for every company or every stage of business. Factors to weigh up include:

• Sales Cycle Length: If your deals take months to close, straight commission can demoralise new hires who may go too long without pay.
• Team Culture: Commission-only roles often suit self-starters or experienced salespeople. Less experienced team members may need more support and job security.
• Cashflow and Admin: Tracking sales, managing pay disputes, and topping up minimum wage when needed can be admin-heavy – be sure you’re set up for this.

Depending on your growth plans, you may also want to ensure your commission structure fits within a wider business framework. For example, if you’re planning to build an online business or start a new venture, commission-only roles might need to be adapted for remote teams, marketplace sellers, or more complex incentive schemes.

Essential Documents For Commission Only Sales Positions

Getting your documentation right is not just best practice-it’s critical protection. At a minimum, you should have:

• Commission or Employee Agreement (tailored for sales roles with detailed commission clauses)
• Contractor Agreement (if using independent salespeople)
• Employee Commission Agreement (if the salesperson is an employee – spells out pay, commission, and status)
• Staff Handbook or Workplace Policy (to cover code of conduct, grievance policies, and commission rules in everyday language)

What If There’s A Dispute?

No matter how well you plan, commission disputes can still crop up – whether it’s about payment timing, targets, or what counts as a “completed sale.” That’s why crystal-clear contracts and written policies are your best friend.

If an issue can’t be resolved informally, follow your company’s written grievance procedure. Employees may then choose to raise a claim at an employment tribunal. Having robust, fair documentation on your side will be crucial in protecting your business if a dispute ever escalates.

Don’t be caught off guard – review your legal foundation and refresh arrangements as your business changes. Chatting to a legal expert can help spot risks before they become problems.
